Java中SpringBoot与2.SpringBoot整合Mybatis的实例

一、创建Springboot的配置文件：application.properties，并添加MyBatis依赖

SpringApplication 会从 application.properties 文件中加载配置信息，下面是添加Spring配置信息的文件目录顺序：

当前目录中

一个 classpath 包下的 /config 目录中

classpath 根目录中

　大家根据自己习惯来即可。

（1）application.properties 文件配置如下：

spring.datasource.driver-class-name=com.mysql.jdbc.Driverspring.datasource.url=jdbc:mysql://127.0.0.1/testspring.datasource.username=rootspring.datasource.password=root

（2）添加 MyBatis 以及 MYSQL

        <!-- SpringBoot - MyBatis -->        <dependency>            <groupId>org.mybatis.spring.boot</groupId>            <artifactId>mybatis-spring-boot-starter</artifactId>            <version>1.2.0</version>        </dependency>        <!-- Mysql -->        <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>        </dependency>

二、创建POJO、Mapper、Service 以及 Controler

（1）User.java

package org.rcddup.app.domain;public class User {    private Long id;    private String name;    private Short age;    private Short status;    public Long getId() {        return id;    }        public void setId(Long id) {            this.id = id;    }        public String getName() {            return name;    }        public void setName(String name) {            this.name = name;    }        public Short getAge() {            return age;    }        public void setAge(Short age) {            this.age = age;    }        public Short getStatus() {            return status;    }        public void setStatus(Short status) {            this.status = status;    }}

（2）UserMapper.java

package org.rcddup.app.dao;import java.util.List;import org.apache.ibatis.annotations.Mapper;import org.apache.ibatis.annotations.Select;import org.rcddup.app.domain.User;@Mapperpublic interface UserMapper {        @Select("select id, name, age, status from user")    List<User> listUser();        @Select("select id, name, age, status from user where id=#{id}")    User getUserById(Long id);    }

（3）IUserService.java

package org.rcddup.app.service;import java.util.List;import org.rcddup.app.domain.User;public interface IUserService {        List<User> listUser();        User getUserById(Long id);    }

（4）UserService.java

package org.rcddup.app.service.impl;import java.util.List;import org.rcddup.app.dao.UserMapper;import org.rcddup.app.domain.User;import org.rcddup.app.service.IUserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;@Servicepublic class UserService implements IUserService{        @Autowired        private UserMapper userMapper;        @Override        public List<User> listUser() {            return userMapper.listUser();    }    @Override        public User getUserById(Long id) {            return userMapper.getUserById(id);    }    }

（5）UserController.java

package org.rcddup.app.web.controller;import java.util.List;import org.rcddup.app.domain.User;import org.rcddup.app.service.IUserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("/user")public class UserController {        @Autowired        private IUserService userService;        @RequestMapping("/list")        public List<User> list() {            return userService.listUser();    }        @RequestMapping("/get")        public User list(Long id) {            return userService.getUserById(id);    }    }

　　重新启动 App.java

　　输入：http://localhost:8080/user/get?id=1

　　输入：http://localhost:8080/user/list

　　到此，SpringBoot整合Mybatis就成功了。
