第二步、配置application.yml和application-dev.yml文件
spring:
profiles:
active: dev
server:
port: 80
spring:
datasource:
url: jdbc:mysql://localhost:3306/db?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
mybatis:
mapper-locations: classpath:mapper/*Mapper.xml
type-aliases-package: com.kyy.springboot.mybatis.entity
logging:
level:
com:
kyy:
springboot:
mybatis:
mapper: debug
第三步、创建entity、mapper、service、controller文件
package com.kyy.springboot.mybatis.entity;
/**
* Auth: zhouhongliang
* Date:2019/8/4
*/
public class AuthUser {
private Long userSid;
private String userCode;
private String userName;
public Long getUserSid() {
return userSid;
}
public void setUserSid(Long userSid) {
this.userSid = userSid;
}
public String getUserCode() {
return userCode;
}
public void setUserCode(String userCode) {
this.userCode = userCode;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
package com.kyy.springboot.mybatis.mapper;
import com.kyy.springboot.mybatis.entity.AuthUser;
import org.springframework.stereotype.Repository;
/**
* Auth: zhouhongliang
* Date:2019/8/4
*/
@Repository
public interface AuthUserMapper {
public AuthUser selectAuthUser(Long userSid);
}
package com.kyy.springboot.mybatis.service;
import com.kyy.springboot.mybatis.entity.AuthUser;
import com.kyy.springboot.mybatis.mapper.AuthUserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* Auth: zhouhongliang
* Date:2019/8/4
*/
@Service
public class AuthUserService {
@Autowired
private AuthUserMapper authUserMapper;
public AuthUser getAuthUser(Long userSid){
return authUserMapper.selectAuthUser(userSid);
}
}
package com.kyy.springboot.mybatis.controller;
import com.kyy.springboot.mybatis.entity.AuthUser;
import com.kyy.springboot.mybatis.service.AuthUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* Auth: zhouhongliang
* Date:2019/8/4
*/
@RestController
public class AuthUserController {
@Autowired
private AuthUserService authUserService;
@RequestMapping("/findAuthUser/{userSid}")
public AuthUser findAuthUser(@PathVariable Long userSid){
return authUserService.getAuthUser(userSid);
}
}
USER_SID,USER_CODE,USER_NAME
第四步、创建启动类
package com.kyy.springboot.mybatis;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Auth: zhouhongliang
* Date:2019/8/4
*/
@SpringBootApplication
@MapperScan(basePackages = {"com.kyy.springboot.mybatis.mapper"})
public class ApplicationStart {
public static void main(String[] args) {
SpringApplication.run(ApplicationStart.class,args);
}
}
第五步、启动项目,访问http://localhost/findAuthUser/1003
输出:{"userSid":1003,"userCode":"10000128","userName":"管理员"}
