配置数据库
server:
port: 8099
spring:
datasource:
username: root
password: 11111
url: jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
driver-class-name: com.mysql.jdbc.Driver
## 该配置节点为独立的节点，如果将这个配置放在spring的节点下，会导致配置无法被识别
mybatis:
mapper-locations: classpath:mapping/*.xml #注意：一定要对应mapper映射xml文件的所在路径
type-aliases-package: com.fff.entity # 注意：对应实体类的路径
数据库新增User表
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`rowguid` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '唯一标识',
`username` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '用户姓名',
`loginid` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '用户登录名',
`password` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '用户登录密码',

PRIMARY KEY (`rowguid`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
SET FOREIGN_KEY_CHECKS = 1;
新增用户实体
package com.fff.entity;
import java.util.Date;
/**
* 描述： 用户实体
*/
public class User {
String rowguid;
String username;
String loginid;
String password;
String phone;
Date lastlogintime;
String enabled;
public User() {
}
public User(String rowguid, String username, String loginid, String password, String phone, Date lastlogintime, String enabled) {
this.rowguid = rowguid;
this.username = username;
this.loginid = loginid;
this.password = password;
this.phone = phone;
this.lastlogintime = lastlogintime;
this.enabled = enabled;
}
public String getRowguid() {
return rowguid;
}
public void setRowguid(String rowguid) {
this.rowguid = rowguid;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getLoginid() {
return loginid;
}
public void setLoginid(String loginid) {
this.loginid = loginid;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public Date getLastlogintime() {
return lastlogintime;
}
public void setLastlogintime(Date lastlogintime) {
this.lastlogintime = lastlogintime;
}
public String getEnabled() {
return enabled;
}
public void setEnabled(String enabled) {
this.enabled = enabled;
}
}
新增用户Mapper接口
package com.fff.mapper;
import com.fff.entity.User;
import org.apache.ibatis.annotations.*;
import org.springframework.stereotype.Component;
import java.util.List;
/**
* 描述： 用户Mapper
*/
@Mapper
public interface UserMapper {
/**
* 新增一个用户
* @param user
* @return
*/
@Insert("insert into user values (#{rowguid}, #{username}, #{loginid}, #{password}, #{phone}, #{lastlogintime}, #{enabled})")
int addNewUser(User user);
/**
* 删除一个用户
* @param rowguid
* @return
*/
@Delete("delete from user where rowguid=#{rowguid}")
int removeUserByGuid(String rowguid);
/**
* 修改用户密码
* @param user
* @return
*/
@Update("update user set password=#{password} where rowguid=#{rowguid}")
int updateUserInfo(User user);
/**
* 根据用户Guid查询一个用户
* @param rowguid
* @return
*/
@Select("select * from user where rowguid=#{rowguid}")
User findUserByGuid(String rowguid);
/**
* 查询所有用户
* @return
*/
@Select("select * from user")
List<User> findAllUsers();
}
新增用户Service
接口
package com.fff.service.api;
import com.fff.entity.User;
import java.util.List;
/**
* 描述： 用户service接口
*/
public interface IUserService {
/**
* 新增一个用户
* @param user
* @return
*/
int addNewUser(User user);
/**
* 删除一个用户
* @param rowguid
* @return
*/
int removeUserByGuid(String rowguid);
/**
* 修改用户密码
* @param user
* @return
*/
int updateUserInfo(User user);
/**
* 根据用户Guid查询一个用户
* @param rowguid
* @return
*/
User findUserByGuid(String rowguid);
/**
* 查询所有用户
* @return
*/
List<User> findAllUsers();
}
实现类
package com.fff.service.impl;
import com.fff.entity.User;
import com.fff.mapper.UserMapper;
import com.fff.service.api.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
* 描述： 用户service实现类
*/
@Service
public class UserService implements IUserService {
@Autowired
private UserMapper userMapper;
@Override
public int addNewUser(User user) {
return userMapper.addNewUser(user);
}
@Override
public int removeUserByGuid(String rowguid) {
return userMapper.removeUserByGuid(rowguid);
}
@Override
public int updateUserInfo(User user) {
return userMapper.updateUserInfo(user);
}
@Override
public User findUserByGuid(String rowguid) {
return userMapper.findUserByGuid(rowguid);
}
@Override
public List<User> findAllUsers() {
return userMapper.findAllUsers();
}
}
Controller调用Service
package com.fff.controller;
import com.fff.entity.User;
import com.fff.service.api.IUserService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Date;
import java.util.UUID;
/**
* 测试Controller
*/
@RestController
@RequestMapping("/test")
public class TestController {
private static final Logger logger = LoggerFactory.getLogger(TestController.class);
@Autowired
private IUserService userService;
@RequestMapping(value = "/test", method = RequestMethod.GET)
public String test(){
User user = new User();
user.setRowguid(UUID.randomUUID().toString());
user.setUsername("Faep");
user.setLoginid("Faep");
user.setPassword("11111");
user.setLastlogintime(new Date());
user.setPhone("18888888888");
user.setEnabled("1");
userService.addNewUser(user);
logger.info(LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")) + "-接口被调用");
return "新增用户成功！";
}
}
启动类添加mapper扫描
package com.fff.application;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
/**
* 描述： SpringBoot启动类
*/
@SpringBootApplication
@ComponentScan(basePackages = {"com.faep"})
@MapperScan(basePackages = {"com.faep.mapper"})
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
