SSM整合，直接抄，项目起不来算我输

SSM整合，直接抄，项目起不来算我输 哪些人适合

快速搭建SSM环境知道其中原理，或者不深究原理的对版本的追求不是非最新不可的 1、项目结构

2、从上往下直接COPY 2-1、类文件

com.test.ssm.controller.StudentController

package com.test.ssm.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("getStudent")
public class StudentController{
    @RequestMapping("student")
    public String toStudent() {
        return "student"; //转到是哪个 视图文件 --》对应的就是student.jsp
    }
}

com.test.ssm.mapper.StudentMapper

package com.test.ssm.mapper;

import com.test.ssm.pojo.Student;
import org.apache.ibatis.annotations.Param;

public interface StudentMapper {
    Student getStudent(@Param("id") Integer id);
}

com.test.ssm.pojo.Student

package com.test.ssm.pojo;

import lombok.Data;
@Data
public class Student {
    private Integer id;
    private String name;
    private Integer age;
}

2-2、resources下的配置文件

mybatis/mapper/StudentMapper.xml

    
		select * from student where id = #{id}
	

mybatis/mybatis-config.xml

spring/applicationContext.xml

spring/applicationContext-mybatis.xml

spring/applicationContext-service.xml

spring/springmvc-servlet.xml

jdbc.properties(直接在resources下面)

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/jack
jdbc.username=root
jdbc.password=root

log4j.properties(直接在resources下面;没有解决最近爆出来的漏洞的，就是自己搭的小demo)

log4j.rootLogger=INFO,A1
log4j.logger.org.apache=INFO
log4j.appender.A1.Target=System.err
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%n

2-3、webapp下面的

/WEB-INF/views/student.jsp

    
        ID
        用户名
        姓名
        年龄
        生日
        创建日期
        更新日期
    

/WEB-INF/web.xml

    ssm_integrate


    
    
        org.springframework.web.context.ContextLoaderListener
    
    
        contextConfigLocation
        classpath:spring/applicationContext*.xml
    
    
    
        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF8
        
    
    
        encodingFilter
        /*
    

    
    
        springmvc
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:spring/springmvc-servlet.xml
        
        1
    

    
        springmvc
        /
    

    
        index.jsp
    

webapp下面的index.jsp

<%--WEB-INF下的资源不能通过URL直接访问，需要Controller转发，所以index.jsp放外面--%>

    Hello World

3、工程的pom文件

4、最后补一个测试

com.test.ssm.mapper.StudentMapperTest

package com.test.ssm.mapper;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring/applicationContext.xml",
        "classpath:spring/applicationContext-mybatis.xml" })
public class StudentMapperTest {
@Autowired
private StudentMapper studentMapper;
    @Test
    public void getStudent() {
        System.out.println(studentMapper.getStudent(1));
    }
}

5、SQL语句

studen表（我的url配置的是jack数据库下，请自行创建在对应的库）

CREATE TABLE `student` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `age` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4;

插入数据

insert into student (name,age) values ('张三',18);
