3.application.properties编写
1 # 驱动配置信息 2 spring.datasource.type=com.alibaba.druid.pool.DruidDataSource 3 spring.datasource.url = jdbc:mysql://127.0.0.1:3306/springbootdb 4 spring.datasource.username = root 5 spring.datasource.password = root 6 spring.datasource.driverClassName = com.mysql.jdbc.Driver 7 8 # mybatis 9 mybatis.type-aliases-package=com.goku.demo.model 10 mybatis.mapper-locations=classpath:mapping/**/*.xml
4.mybatis.generator代码生成器
generatorConfig.xml修改具体表内容github
1 <!-- !!!! Table Configurations !!!! --> 2 <table tableName="user_" domainObjectName="User" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" 3 enableUpdateByExample="false"/>
执行代码生成web
查看生成代码 model,mapper,mappingspring
5.service层
UserService接口类编写sql
1 package com.goku.demo.service; 2 3 import com.goku.demo.model.UserWithBLOBs; 4 5 /** 6 * Created by nbfujx on 2017-12-01. 7 */ 8 public interface UserService { 9 UserWithBLOBs selectByPrimaryKey(String id); 10 }
UserServiceImpl接口实现类编写数据库
1 package com.goku.demo.service.impl; 2 3 import com.goku.demo.mapper.UserMapper; 4 import com.goku.demo.model.UserWithBLOBs; 5 import com.goku.demo.service.UserService; 6 import org.springframework.beans.factory.annotation.Autowired; 7 import org.springframework.stereotype.Service; 8 9 /** 10 * Created by nbfujx on 2017-12-01. 11 */ 12 @Service("UserService_one") 13 public class UserServiceImpl implements UserService { 14 15 @Autowired 16 UserMapper userMapper; 17 18 @Override 19 public UserWithBLOBs selectByPrimaryKey(String id) { 20 return userMapper.selectByPrimaryKey(id); 21 } 22 }
6.controller层
UserController接口类编写apache
1 package com.goku.demo.controller; 2 3 import com.goku.demo.model.UserWithBLOBs; 4 5 /** 6 * Created by nbfujx on 2017-12-01. 7 */ 8 public interface UserController { 9 UserWithBLOBs selectByPrimaryKey(String id); 10 }
UserControllerImpl接口实现类编写springboot
1 package com.goku.demo.controller.impl; 2 3 import com.goku.demo.controller.UserController; 4 import com.goku.demo.model.UserWithBLOBs; 5 import com.goku.demo.service.UserService; 6 import org.springframework.beans.factory.annotation.Autowired; 7 import org.springframework.beans.factory.annotation.Qualifier; 8 import org.springframework.web.bind.annotation.PathVariable; 9 import org.springframework.web.bind.annotation.RequestMapping; 10 import org.springframework.web.bind.annotation.RequestParam; 11 import org.springframework.web.bind.annotation.RestController; 12 13 /** 14 * Created by nbfujx on 2017-12-01. 15 */ 16 @RestController 17 @RequestMapping("/User") 18 public class UserControllerImpl implements UserController { 19 20 @Autowired 21 @Qualifier("UserService_one") 22 UserService userservice; 23 24 @Override 25 @RequestMapping("/{id}") 26 public UserWithBLOBs selectByPrimaryKey(@PathVariable String id) { 27 return userservice.selectByPrimaryKey(id); 28 } 29 }
7.Application启动类编写
1 package com.goku.demo; 2 3 import org.mybatis.spring.annotation.MapperScan; 4 import org.springframework.boot.SpringApplication; 5 import org.springframework.boot.autoconfigure.SpringBootApplication; 6 import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; 7 import org.springframework.boot.web.servlet.ServletComponentScan; 8 9 /** 10 * Created by nbfujx on 2017/11/20. 11 */ 12 // Spring Boot 应用的标识 13 @SpringBootApplication 14 @ServletComponentScan 15 @MapperScan(basePackages="com.goku.demo.mapper") 16 public class DemoApplication { 17 18 public static void main(String[] args) { 19 // 程序启动入口 20 // 启动嵌入式的 Tomcat 并初始化 Spring 环境及其各 Spring 组件 21 SpringApplication.run(DemoApplication.class,args); 22 } 23 }
