怎么搭建springmvc和mybatis

SpringMVC+MyBatis+Freemarker 简单框架搭建（一）

一、开发环境：

Eclipse、Tomcat、SVN等请参见如下的帖子，很详细了。

http://www.iteye.com/topic/982182

svn和maven插件的安装：

1、先安装gef插件

地址：http://download.eclipse.org/tools/gef/updates/interim/

2、安装svn插件

地址：http://subclipse.tigris.org/update_1.6.x

3、maven插件

m2eclipse-core Update 地址： http://m2eclipse.sonatype.org/sites/m2e

m2eclipse-extras Update 地市： http://m2eclipse.sonatype.org/sites/m2e-extras

4、安装可能出现的问题

直接在线安装maven2 会出现依赖插件找不到的问题，无法安装。必须先安装gef 插件后才能安 装m2eclipse-core 插件，然而安装m2eclipse-extras 插件又依赖subclipse 插件。所以，三个插 件的正确的安装顺序是：gef插件 》subclipse插件 》m2eclipse插件

二、web.xml 和 applicationContext.xml 配置

1、web.xml文件配置：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

version="2.5">

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext.xml</param-value>

</context-param>

<!-- Spring MVC 配置 -->

<servlet>

<servlet-name>springServlet</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:contextConfigLocation-springService.xml</param-value>

</init-param>

<load-on-startup>0</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>springServlet</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<!-- 事件监听器 -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- shiro 权限控制的过滤器 -->

<!-- Spring 刷新Introspector防止内存泄露 -->

<listener>

<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>

</listener>

<!-- session超时定义,单位为分钟 -->

<session-config>

<session-timeout>20</session-timeout>

</session-config>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

<!-- 设置servlet编码开始 -->

<filter>

<filter-name>Set Character Encoding</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>GB2312</param-value>

</init-param>

<init-param>

<param-name>forceEncoding</param-name>

<param-value>true</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>Set Character Encoding</filter-name>

<url-pattern>/</url-pattern>

</filter-mapping>

<!-- 设置servlet编码结束 -->

<display-name>Archetype Created Web Application</display-name>

</web-app>

<context-param>节点和<listener>节点是web项目启动时最先读取的两个节点，所以这两个节点里面所配置的内容是web项目启动时最先加载的部分。

<context-param>节点中配置的applicationContext.xml里面主要是数据库的配置信息，以及事务等等

<listener>节点配置的是web请求的监听器

2、applicationContext.xml 内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"

xmlns:p="http://www.springframework.org/schema/p"

xsi:schemaLocation="

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd

">

<!-- 自动注解除Controller以外的Component -->

<context:component-scan base-package="com.weiluo.example">

<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

</context:component-scan>

<!-- 此配置可以让我们以${xxx}的形式来读取property.properties里面的信息 -->

<!-- <context:property-placeholder/>-->

<bean id="propertyConfigurer"

class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="locations">

<list>

<value>classpath:jdbc.properties</value>

</list>

</property>

</bean>

<!-- 配置数据源 -->

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

<property name="driverClassName" value="${jdbc.driver}"></property>

<property name="url"

value="${jdbc.url}"></property>

<property name="username" value="${jdbc.username}"></property>

<property name="password" value="${jdbc.password}"></property>

<!-- Connection Pooling Info -->

<property name="maxActive" value="${dbcp.maxActive}" />

<property name="maxIdle" value="${dbcp.maxIdle}" />

<property name="defaultAutoCommit" value="false" />

<!-- 连接Idle一个小时后超时 -->

<property name="timeBetweenEvictionRunsMillis" value="360000" />

<property name="minEvictableIdleTimeMillis" value="360000" />

</bean>

<!-- 配置SessionFactory -->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"

p:dataSource-ref = "dataSource"

p:configLocation = "classpath:sqlMapConfig.xml" />

<!-- 采用spring与mybatis整合的第二种方法 -->

<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">

<constructor-arg index="0" ref="sqlSessionFactory" />

</bean>

<!-- 配置事务管理器 -->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"

p:dataSource-ref = "dataSource" />

<!-- MapperScanner配置，自动搜索mapper里面的对象，并注入 -->

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"

p:basePackage = "com.weiluo.example.entity" />

<!-- 启动Spring注解事务 -->

<tx:annotation-driven/>

</beans>

3、web.xml中的<servlet>节点配置的是与请求处理相关的一些内容，主要是 url路由处理器，视图解析器，等等，如下：

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="

http://www.springframework.org/schema/util

http://www.springframework.org/schema/util/spring-util-3.1.xsd

http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.1.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">

<!-- url映射拦截器 -->

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">

<property name="order" value="1" />

</bean>

<!-- 配置数据格式转换器 -->

<bean

class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

<property name="messageConverters">

<list>

<ref bean="jsonHttpMessageConverter" />

</list>

</property>

</bean>

<bean id="jsonHttpMessageConverter"

class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

</bean>

<!-- 开启controller注解支持 -->

<!-- 注：如果base-package=cn.javass 则注解事务不起作用 TODO 读源码 -->

<context:component-scan base-package="com.weiluo.example.controller">

<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

</context:component-scan>

<!-- 因为web-inf目录下面的静态资源文件是不能直接通过目录过去的，所以需要特殊声明-->

<mvc:resources location="/static/" mapping="/static/**" />

<!-- 视图解析器 -->

<bean id="viewResolver"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

<property name="cache" value="true" />

<property name="prefix" value="" />

<property name="suffix" value=".html" />

<property name="exposeSpringMacroHelpers" value="true" />

<property name="exposeRequestAttributes" value="true" />

<property name="exposeSessionAttributes" value="true" />

<property name="requestContextAttribute" value="rc" />

<property name="contentType" value="text/htmlcharset=GB2312" />

<property name="order" value="0"/>

</bean>

<!-- 自定义的freemarker标签 -->

<bean id="blockDirective"

class="com.weiluo.example.freemarker.directive.BlockDirective" />

<bean id="extendsDirective"

class="com.weiluo.example.freemarker.directive.ExtendsDirective" />

<bean id="overrideDirective"

class="com.weiluo.example.freemarker.directive.OverrideDirective" />

<bean id="superDirective"

class="com.weiluo.example.freemarker.directive.SuperDirective" />

<!-- freemarker的配置项 -->

<bean id="freemarkerConfig"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">

<property name="templateLoaderPath" value="/WEB-INF/views/" />

<property name="freemarkerSettings">

<props>

<prop key="template_update_delay">5</prop>

<prop key="defaultEncoding">GB2312</prop>

<prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>

<prop key="date_format">yyyy-MM-dd</prop>

<prop key="time_format">HH:mm:ss</prop>

<prop key="number_format">0.######</prop>

<prop key="whitespace_stripping">true</prop>

</props>

</property>

<property name="freemarkerVariables">

<map>

<entry key="extends" value-ref="extendsDirective"></entry>

<entry key="override" value-ref="overrideDirective"></entry>

<entry key="block" value-ref="blockDirective"></entry>

<entry key="super" value-ref="superDirective"></entry>

</map>

</property>

</bean>

</beans>

4、另外，一些常常变化的信息习惯于存放在application.properties文件里面，如：

#oracle version database setting

database=sqlserver

#jdbc.driver=oracle.jdbc.driver.OracleDriver

jdbc.driver=net.sourceforge.jtds.jdbc.Driver

#jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:jtds:sqlserver://127.0.0.1:1433databaseName=SpringMyBatisExample

#jdbc.url=jdbc:mysql://localhost:3306/springmvcdemo

jdbc.username=sa

jdbc.password=sasa

#dbcp settings

dbcp.maxIdle=5

dbcp.maxActive=20

到这里，一个spring mvc的基本框架就已经搭建起来了。

后续再完成数据库mybatis的配置以及freemarker的配置。

SpringMVC+MyBatis+Freemarker 简单框架搭建（一）

一、开发环境：

Eclipse、Tomcat、SVN等请参见如下的帖子，很详细了。

http://www.iteye.com/topic/982182

svn和maven插件的安装：

1、先安装gef插件

地址：http://download.eclipse.org/tools/gef/updates/interim/

2、安装svn插件

地址：http://subclipse.tigris.org/update_1.6.x

3、maven插件

m2eclipse-core Update 地址： http://m2eclipse.sonatype.org/sites/m2e

m2eclipse-extras Update 地市： http://m2eclipse.sonatype.org/sites/m2e-extras

4、安装可能出现的问题

直接在线安装maven2 会出现依赖插件找不到的问题，无法安装。必须先安装gef 插件后才能安 装m2eclipse-core 插件，然而安装m2eclipse-extras 插件又依赖subclipse 插件。所以，三个插 件的正确的安装顺序是：gef插件 》subclipse插件 》m2eclipse插件

二、web.xml 和 applicationContext.xml 配置

1、web.xml文件配置：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

version="2.5">

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext.xml</param-value>

</context-param>

<!-- Spring MVC 配置 -->

<servlet>

<servlet-name>springServlet</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:contextConfigLocation-springService.xml</param-value>

</init-param>

<load-on-startup>0</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>springServlet</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<!-- 事件监听器 -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- shiro 权限控制的过滤器 -->

<!-- Spring 刷新Introspector防止内存泄露 -->

<listener>

<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>

</listener>

<!-- session超时定义,单位为分钟 -->

<session-config>

<session-timeout>20</session-timeout>

</session-config>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

<!-- 设置servlet编码开始 -->

<filter>

<filter-name>Set Character Encoding</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>GB2312</param-value>

</init-param>

<init-param>

<param-name>forceEncoding</param-name>

<param-value>true</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>Set Character Encoding</filter-name>

<url-pattern>/</url-pattern>

</filter-mapping>

<!-- 设置servlet编码结束 -->

<display-name>Archetype Created Web Application</display-name>

</web-app>

<context-param>节点和<listener>节点是web项目启动时最先读取的两个节点，所以这两个节点里面所配置的内容是web项目启动时最先加载的部分。

<context-param>节点中配置的applicationContext.xml里面主要是数据库的配置信息，以及事务等等

<listener>节点配置的是web请求的监听器

2、applicationContext.xml 内容如下：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

">

<!-- 自动注解除Controller以外的Component -->

<context:component-scan base-package="com.weiluo.example">

<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

</context:component-scan>

<!-- 此配置可以让我们以${xxx}的形式来读取property.properties里面的信息 -->

<!-- <context:property-placeholder/>-->

<bean id="propertyConfigurer"

</bean>

<!-- 配置数据源 -->

<!-- 连接Idle一个小时后超时 -->

<property name="timeBetweenEvictionRunsMillis" value="360000" />

<property name="minEvictableIdleTimeMillis" value="360000" />

</bean>

<!-- 配置SessionFactory -->

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"

p:dataSource-ref = "dataSource"

p:configLocation = "classpath:sqlMapConfig.xml" />

<!-- 采用spring与mybatis整合的第二种方法 -->

<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">

<constructor-arg index="0" ref="sqlSessionFactory" />

</bean>

<!-- 配置事务管理器 -->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"

p:dataSource-ref = "dataSource" />

<!-- MapperScanner配置，自动搜索mapper里面的对象，并注入 -->

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"

p:basePackage = "com.weiluo.example.entity" />

<!-- 启动Spring注解事务 -->

<tx:annotation-driven/>

</beans>

3、web.xml中的<servlet>节点配置的是与请求处理相关的一些内容，主要是 url路由处理器，视图解析器，等等，如下：

<beans xmlns="http://www.springframework.org/schema/beans"

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.1.xsd

http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">

<!-- url映射拦截器 -->

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">

<property name="order" value="1" />

</bean>

<!-- 配置数据格式转换器 -->

<bean

class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

<property name="messageConverters">

<list>

<ref bean="jsonHttpMessageConverter" />

</list>

</property>

</bean>

<bean id="jsonHttpMessageConverter"

class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

</bean>

<!-- 开启controller注解支持 -->

<!-- 注：如果base-package=cn.javass 则注解事务不起作用 TODO 读源码 -->

<context:component-scan base-package="com.weiluo.example.controller">

<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>

</context:component-scan>

<!-- 因为web-inf目录下面的静态资源文件是不能直接通过目录过去的，所以需要特殊声明-->

<mvc:resources location="/static/" mapping="/static/**" />

<!-- 视图解析器 -->

<bean id="viewResolver"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

<property name="cache" value="true" />

<property name="prefix" value="" />

<property name="suffix" value=".html" />

<property name="exposeSpringMacroHelpers" value="true" />

<property name="exposeRequestAttributes" value="true" />

<property name="exposeSessionAttributes" value="true" />

<property name="requestContextAttribute" value="rc" />

<property name="contentType" value="text/htmlcharset=GB2312" />

<property name="order" value="0"/>

</bean>

<!-- 自定义的freemarker标签 -->

<bean id="blockDirective"

class="com.weiluo.example.freemarker.directive.BlockDirective" />

<bean id="extendsDirective"

class="com.weiluo.example.freemarker.directive.ExtendsDirective" />

<bean id="overrideDirective"

class="com.weiluo.example.freemarker.directive.OverrideDirective" />

<bean id="superDirective"

class="com.weiluo.example.freemarker.directive.SuperDirective" />

<!-- freemarker的配置项 -->

<bean id="freemarkerConfig"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">

<property name="templateLoaderPath" value="/WEB-INF/views/" />

<property name="freemarkerSettings">

<props>

<entry key="block" value-ref="blockDirective"></entry>

<entry key="super" value-ref="superDirective"></entry>

</map>

</property>

</bean>

</beans>

4、另外，一些常常变化的信息习惯于存放在application.properties文件里面，如：

#oracle version database setting

database=sqlserver

#jdbc.driver=oracle.jdbc.driver.OracleDriver

jdbc.driver=net.sourceforge.jtds.jdbc.Driver

#jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:jtds:sqlserver://127.0.0.1:1433databaseName=SpringMyBatisExample

#jdbc.url=jdbc:mysql://localhost:3306/springmvcdemo

jdbc.username=sa

jdbc.password=sasa

#dbcp settings

dbcp.maxIdle=5

dbcp.maxActive=20

到这里，一个spring mvc的基本框架就已经搭建起来了。

后续再完成数据库mybatis的配置以及freemarker的配置。

去买个阿里或者腾讯云主机,基础配置的一个月也就几十块钱.这相当于你自己的一台电脑. 你可以在上面安装tomcat mysql 并将你的项目部署上去,就像你在自己电脑上中部署的一样. 完成这些工作后.你可以购买一个域名.然后将域名和你的云主机绑定.这样就可以在互联网上使用你的项目了.淘宝上买的空间有的可能不支持jsp的部署.
