 </project>

3.application.properties编写

 # 驱动配置信息
 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
 spring.datasource.url = jdbc:mysql://127.0.0.1:3306/springbootdb
 spring.datasource.username = root
 spring.datasource.password = root
 spring.datasource.driverClassName = com.mysql.jdbc.Driver

 # mybatis
 mybatis.type-aliases-package=com.goku.demo.model
 mybatis.mapper-locations=classpath:mapping/**/*.xml

4.mybatis.generator代码生成器

generatorConfig.xml修改具体表内容

         <!-- !!!! Table Configurations !!!! -->
         <table tableName="user_" domainObjectName="User" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
                enableUpdateByExample="false"/>

执行代码生成

 查看生成代码 model,mapper,mapping

5.service层

UserService接口类编写

 package com.goku.demo.service;

 import com.goku.demo.model.UserWithBLOBs;

 /**
  * Created by nbfujx on 2017-12-01.
  */
 public interface UserService {
     UserWithBLOBs selectByPrimaryKey(String id);
 }

UserServiceImpl接口实现类编写

 package com.goku.demo.service.impl;

 import com.goku.demo.mapper.UserMapper;
 import com.goku.demo.model.UserWithBLOBs;
 import com.goku.demo.service.UserService;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.stereotype.Service;

 /**
  * Created by nbfujx on 2017-12-01.
  */
 @Service("UserService_one")
 public class UserServiceImpl implements UserService {

     @Autowired
     UserMapper userMapper;

     @Override
     public UserWithBLOBs selectByPrimaryKey(String id) {
         return userMapper.selectByPrimaryKey(id);
     }
 }

6.controller层

UserController接口类编写

 package com.goku.demo.controller;

 import com.goku.demo.model.UserWithBLOBs;

 /**
  * Created by nbfujx on 2017-12-01.
  */
 public interface UserController {
     UserWithBLOBs selectByPrimaryKey(String id);
 }

UserControllerImpl接口实现类编写

 package com.goku.demo.controller.impl;

 import com.goku.demo.controller.UserController;
 import com.goku.demo.model.UserWithBLOBs;
 import com.goku.demo.service.UserService;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.beans.factory.annotation.Qualifier;
 import org.springframework.web.bind.annotation.PathVariable;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.bind.annotation.RequestParam;
 import org.springframework.web.bind.annotation.RestController;

 /**
  * Created by nbfujx on 2017-12-01.
  */
 @RestController
 @RequestMapping("/User")
 public class UserControllerImpl implements UserController {

     @Autowired
     @Qualifier("UserService_one")
     UserService userservice;

     @Override
     @RequestMapping("/{id}")
     public UserWithBLOBs selectByPrimaryKey(@PathVariable String id) {
         return userservice.selectByPrimaryKey(id);
     }
 }

7.Application启动类编写

 package com.goku.demo;

 import org.mybatis.spring.annotation.MapperScan;
 import org.springframework.boot.SpringApplication;
 import org.springframework.boot.autoconfigure.SpringBootApplication;
 import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
 import org.springframework.boot.web.servlet.ServletComponentScan;

 /**
  * Created by nbfujx on 2017/11/20.
  */
 // Spring Boot 应用的标识
 @SpringBootApplication
 @ServletComponentScan
 @MapperScan(basePackages="com.goku.demo.mapper")
 public class DemoApplication {

     public static void main(String[] args) {
         // 程序启动入口
         // 启动嵌入式的 Tomcat 并初始化 Spring 环境及其各 Spring 组件
         SpringApplication.run(DemoApplication.class,args);
     }
 }
