本demo只是对SSM框架进行整合搭建的一个demo，并不包含其他的功能，只供ssm框架整合借鉴。
先对spring和springMVC框架进行整合- 导入pom依赖

- web.xml文件配置dispatcherServlet和字符过滤器

- 建立springmvc.xml文件
<context:component-scan base-package="com.demo.ssm.controller"/>
<mvc:annotation-driven/>
<bean id="view" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
bean>
<mvc:default-servlet-handler>mvc:default-servlet-handler>
<mvc:resources mapping="/images/**" location="/images/"/>
<mvc:resources mapping="/css/**" location="/css/"/>
<mvc:resources mapping="/js/**" location="/js/"/>
-
建立各个package，完整demo结构如图所示
-
在controller中编写test方法测试springMVC是否能够正常运行
@Controller
@RequestMapping("/admin")
public class AdminController {
@Autowired
private AdminService adminService;
@GetMapping("/getOneAdmin")
public String test(Model model) {
Admin admin = adminService.getOneAdmin();
System.out.println(JSON.toJSONString(admin));
model.addAttribute("admin", admin);
return "t";
}
}
index.jsp文件内容
<body>
<a href="${pageContext.request.contextPath}/admin/getOneAdmin">测试a>
body>
t.jsp文件内容
<body>
这里是测试界面...
body>
到此为止，部署tomcat之后能够正常从index.jsp页面跳转到t.jsp页面，说明springMVC搭建成功。
如果页面跳转时出现404页面找不到
在Project Structure下Artifacts中选择项目 ->WEB-INF，在这个文件夹下新建lib文件夹，然后点击+号然后选择所有的library文件并保存，重启服务器即可
建立applicationContext.xml文件配置mybatis相关的内容
<context:property-placeholder location="classpath:db.properties"/>
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="initialSize" value="5"/>
<property name="minIdle" value="5"/>
<property name="maxActive" value="20"/>
<property name="maxWait" value="60000"/>
bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="typeAliasesPackage" value="com.demo.ssm.pojo">property>
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
bean>
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.demo.ssm.dao"/>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
bean>
<context:component-scan base-package="com.demo.ssm">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
context:component-scan>
<bean id="tx" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
bean>
<tx:annotation-driven transaction-manager="tx"/>
接下来在service和dao层分别编写一个getOneAdmin方法测试是否能够成功从数据库查询到数据
AdminMapper内容
public interface AdminMapper {
Admin getOneAdmin();
}
AdminMapper.xml内容
<mapper namespace="com.demo.ssm.dao.AdminMapper">
<select id="getOneAdmin" resultType="com.demo.ssm.pojo.Admin">
SELECT * FROM admin LIMIT 1;
select>
mapper>
AdminService内容
public interface AdminService {
Admin getOneAdmin();
}
AdminServiceImpl内容
@Service("adminService")
public class AdminServiceImpl implements AdminService {
@Autowired
private AdminMapper adminMapper;
@Override
public Admin getOneAdmin() {
System.out.println("test......");
return adminMapper.getOneAdmin();
}
}
db_library.sql文件内容
Navicat MySQL Data Transfer
Source Server : localhost
Source Server Version : 50729
Source Host : localhost:3306
Source Database : db_library
Target Server Type : MYSQL
Target Server Version : 50729
File Encoding : 65001

*/
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for `admin`
-- ----------------------------
DROP TABLE IF EXISTS `admin`;
CREATE TABLE `admin` (
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT 'id',
`username` varchar(20) DEFAULT NULL COMMENT '用户名',
`password` varchar(20) DEFAULT NULL COMMENT '密码',
`adminType` int(11) DEFAULT NULL COMMENT '管理员类型',
PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='管理员';
-- ----------------------------
-- Records of admin
-- ----------------------------
INSERT INTO `admin` VALUES ('1', 'admin', '12345', '1');
INSERT INTO `admin` VALUES ('2', 'test', '12345', '0');
到这里SSM框架整合就完成啦，运行服务器即可测试是否整合成功，后续的功能代码可以在此demo的基础上进行编写。
自己学习的ssm整合的 *** 作，实 *** 了一遍能够正常运行，若小伙伴发现了其他的问题也可以留言交流，共同进步！
