springboot和mybatis整合

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/yxz_test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
server.port=8888
server.context-path=/home
mybatis.config=classpath:mybatis-config.xml

@SpringBootApplication
@Controller
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}

}

public interface UserinfoMapper{
@Select("SELECT * FROM USERINFO WHERE ID=#{ID}")
UserInfo getById(@Param("ID") String ID);

@Insert("INSERT INTO USERINFO(id,userName,birthday) VALUES(#{id},#{userName},#{birthday})")
void saveUser(UserInfo userInfo);

@Update("UPDATE USERINFO SET USERNAME=#{newName} WHERE ID=#{ID}")
void updateUser(@Param("ID") String ID, @Param("newName") String newName);

@Delete("DELETE FROM USERINFO WHERE ID=#{ID}")
void deleteUser(@Param("ID") String ID);
}

@Transactional
@Service("userService")
public class UserServiceImpl implements IUserService{
@Autowired
private UserinfoMapper userinfoMapper;

public void saveUser(UserInfo userInfo) {
userinfoMapper.saveUser(userInfo);;
}
}

七. 创建接口类调用service方法,使用http地址请求

@RestController
@RequestMapping("/yxz/")
public class SaveUser{

@Autowired
private IUserService userService;

@RequestMapping(value="saveUser",method=RequestMethod.POST)
public void saveUser(@RequestBody String requst){
String decode=null;
try {
decode=URLDecoder.decode(requst, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
System.err.println("解码出错");
}
UserInfo userInfo=JSON.parseObject(decode, UserInfo.class);
userService.saveUser(userInfo);
}
}

八. 创建test类进行测试是否连接成功

public class Test {
public static void main(String[] args) {
saveUser();
}

public static void saveUser(){
Map<String, Object> map = new HashMap<String, Object>();
map.put("id", "007");
map.put("userName", "测试员");
map.put("birthday", new Date());
String reqUrl="http://127.0.0.1:8888/home/yxz/saveUser";
HttpUtils.sendPost(reqUrl, JSON.toJSONString(map));
//HttpRequestProxy.doPost(reqUrl, map);
System.out.println("user save successfully");
}
}

注意事项:

1. springboot启动直接启动刚才创建的启动类就可以启动

2. mapper类可以使用注解,也可以使用官方推荐的xml映射

3. 此方法适用于开发rest接口类,可以快速搭建项目,调试打通与否
