第一次使用idea整合ssm
common parent 是父包
edu-api:用于提供给安卓json数据
edu-model:放置pojo类
edu-dao:依赖model,放置和数据库之间的数据操作类
edu-service:依赖dao,具体业务类
edu-manager:控制器,依赖service,只有这个工程是web工程

编写web.xml 加入前端控制器等配置

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
基本框架搭好了
接下来测试一下看看能不能跑起来
编写一个用来测试的pojo类
public class User {
private int id;
private String userName;
private String password;
写mapper接口
package com.ch.edu.mapper.baseMapper;
public interface baseMapper<T> {
public T findByID(Integer id);
public T findByUUID(String uuid);
public void deleteByID(Integer id);
public void deleteByUUID(String uuid);
public void update(T t);
public void insert(T t);
}
public interface UserMapper extends baseMapper<User> {
}
写mapper.xml文件
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.ch.edu.mapper.UserMapper">
<resultMap id="user" type="com.ch.edu.model.User">
<id property="id" column="id"></id>
<result property="userName" column="user_name"/>
<result property="password" column="password"/>
</resultMap>
<select id="findByID" parameterType="int" resultMap="user">
select * from user where id=#{id}
</select>
</mapper>
写service接口以及实现类(在实现类上写service注释)
@Service("userService")
@Transactional
public class UserServiceImpl extends baseServiceImpl<User> implements UserService{
@Override
public User findByID(Integer id) {
System.out.println(userMapper);
return userMapper.findByID(id);
}
写一个简单的测试用的controller
@Controller
@RequestMapping("user")
public class UserController {
@Autowired
UserService userService;
@RequestMapping("login")
public String login(){
System.out.println(userService);
System.out.println("******");
return "login";
}
@RequestMapping("test")
public String test(){
System.out.println(userService);
System.out.println(userService.findByID(1).getUserName());
return null;
}
}
