package com.example.demo.entity;import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import lombok.AllArgsConstructor;
import lombok.Data;import java.sql.Timestamp;Data
AllArgsConstructor
public class User {TableId(value id,type IdType.AUTO)private Integer id;private String username;private String password;private String nickname;private String email;private Timestamp add_time;private Integer disabled;}UserService接口中我们需要添加一个方法 PageUser getPage(PageUser page, QueryWrapperUser queryWrapper);UserServiceImple实现类中实现这个方法 这个方法主要用来实现分页 Autowiredprivate UserMapper userMapper;Overridepublic PageUser getPage(PageUser page, QueryWrapperUser queryWrapper) {return userMapper.selectPage(page,queryWrapper);}UserMapper类和 我们平时写的mapper类一样没有区别 在config包下添加Mybatis-plus分页插件
package com.example.demo.config;import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.OptimisticLockerInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;Configuration
public class MyBatisPlusConfig {Beanpublic MybatisPlusInterceptor mybatisPlusInterceptor() {MybatisPlusInterceptor interceptor new MybatisPlusInterceptor();// 向MyBatis-Plus的过滤器链中添加分页拦截器需要设置数据库类型主要用于分页方言interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
// interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));// 添加乐观锁拦截器interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());return interceptor;}
}UserController控制器类
package com.example.demo.controller;import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.example.demo.entity.User;
import com.example.demo.service.UserService;
import com.example.demo.util.Res;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.web.bind.annotation.*;import java.sql.Timestamp;
import java.util.Date;RestController
RequestMapping(/user)
public class UserController{Autowiredprivate UserService userService;PostMapping(/add)public ResUser add (RequestBody User user){//判断用户是否存在QueryWrapperUser queryWrapper new QueryWrapper();queryWrapper.eq(username,user.getUsername());User u userService.getOne(queryWrapper);if(u!null){return Res.error(用户已存在);}//设置添加时间Timestamp timestamp new Timestamp(new Date().getTime());user.setAdd_time(timestamp);//加密密码BCryptPasswordEncoder bCryptPasswordEncoder new BCryptPasswordEncoder();String hash_password bCryptPasswordEncoder.encode(user.getPassword());user.setPassword(hash_password);boolean res userService.save(user);if(!res){return Res.error(添加失败);}return Res.success(添加用户成功,user);}PostMapping(/edit)public ResUser edit(RequestBody User user){boolean res userService.updateById(user);if(!res){return Res.error(编辑用户信息失败);}return Res.success(编辑用户信息成功,user);}DeleteMapping(/delete/{id})public ResObject delete(PathVariable int id){boolean res userService.removeById(id);if(!res){return Res.error(删除失败);}return Res.success(删除成功,id);}GetMapping(/getid/{id})public ResUser getId(PathVariable int id){User user userService.getById(id);if(user!null){return Res.success(获取数据成功,user);}return Res.error(获取数据失败);}GetMapping(/page)public ResObject page(RequestParam(defaultValue 1) int page,RequestParam(defaultValue 10) int pageSize,RequestParam(defaultValue ) String username,RequestParam(defaultValue ) String nickname){PageUser userPage new Page(page,pageSize);QueryWrapperUser queryWrapper new QueryWrapper();queryWrapper.like(username,username).or().like(nickname,nickname);return Res.success(获取数据成功,userService.getPage(userPage,queryWrapper));}PostMapping(/disabled)public ResObject disabledById(RequestBody User user){boolean res userService.updateById(user);if(res){return Res.success(禁用成功,user);}return Res.error(禁用失败);}PostMapping(/enable)public ResObject enableById(RequestBody User user){boolean res userService.updateById(user);if(res){return Res.success(启用成功,user);}return Res.error(启用失败);}
}在UserController控制器中Res是我们自己封装的返回类
package com.example.demo.util;import lombok.Data;
import org.springframework.stereotype.Component;Data
public class ResT {private Integer code;private String msg;private T data;public static T ResT success(String msg,T data){ResT res new ResT();res.code 200;res.msg msg;res.data data;return res;}public static T ResT error(String msg){ResT res new ResT();res.code 400;res.msg msg;res.data null;return res;}
}配置跨域请求 在config包下配置
package com.example.demo.config;import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
Configuration
public class CorsConfig implements WebMvcConfigurer {Overridepublic void addCorsMappings(CorsRegistry registry) {registry.addMapping(/**)
// .allowedOrigins(*).allowedOriginPatterns(*).allowedMethods(GET, HEAD, POST, PUT, DELETE, OPTIONS).allowCredentials(true).maxAge(3600).allowedHeaders(*).exposedHeaders(*);}
}前端
依赖 dependencies: {axios: ^1.6.4,element-plus: ^2.4.4,pinia: ^2.1.7,sass: ^1.69.7,vue: ^3.3.11,vue-router: ^4.2.5},这里我给axios添加了一个baseUrl可以根据我们自己的需要添加请求头
import axios from axiosconst http axios.create({baseURL:http://127.0.0.1:8000,timeout:5000

后端使用mybatis-plus分页记得添加分页插件 记得配置跨域请求文件 springboot3.2.1 搭配的mybatis-plus 要使用3.5.5其他的会报错
