搭建spring+springmvc+mybatis+maven框架

项目结构：
这里写图片描述

配置文件：
database.properties（与数据库连接）

--sqlserver数据库--
jdbc.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbc.url=jdbc:sqlserver://ip地址：端口号;DatabaseName=数据库名称
jdbc.username=用户名
jdbc.password=密码

--MySQL数据库--
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://ip地址：端口号/数据库名称?useUnicode=true&amp&characterEncoding=utf-8
jdbc.username=用户名
jdbc.password=密码

介绍：
pojo 实体类 ：与数据库相关联

//（当没有构造函数时，默认有无参构造，当有有参构造函数时，默认没有无参构造函数，需要加上无参构造函数，否则，使用无参构造函数是报错）
package com.mb.pojo;
public class User {
private int id;
private String name;
//无参构造
public User() {
super();
}
//有参构造
public User(int id, String name) {
super();
this.id = id;
this.name = name;
}
}

repository接口：与mapper.xml里的方法关联，有一个@Param注解

package com.mb.repository;

import java.util.List;

import org.apache.ibatis.annotations.Param;

import com.mb.pojo.User;

public interface UserRepository {
List<User> getList(@Param("id") int id);
}

service 接口
例子：

package com.mb.service;

import java.util.List;
import com.mb.pojo.User;
public interface UserService {
    List<User> getList(int id);
}

serviceimpl 实现类：实现service接口中所以接口，有一个 @Service
例子：

package com.mb.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.mb.pojo.User;
import com.mb.repository.UserRepository;
import com.mb.service.UserService;
@Service
public class UserServiceImpl implements UserService{
    @Resource
    private UserRepository ur;

    public List<User> getList(int id) {
        return ur.getList(id);
    }

}

mapper :用来写SQL语句和相关的判断
例子：

<?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">
<!--namespace 是repository接口路径-->
<mapper namespace="com.mb.repository.UserRepository">
    <!--id 是接口名称  resultType 是返回类型--!>
    <select id="GetDicListAll" resultType="com.mb.pojo.AppCode">
        SELECT * FROM User  where id=#{id}
    </select>
</mapper>

controller ：与前台交互的类

package com.mb.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import com.google.gson.Gson;
import com.mb.pojo.User;
import com.mb.service.UserService;

@Controller
public class UserController {
    @Resource
    private UserService u;
    //前台调用getList的地址
