后端

1、创建springboot项目2.6.13

2、pom依赖

 <!-- web -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>

            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

3.yml

server:
  port: 9999

spring:
  datasource:
    username: root
    password: 123456
    url: jdbc:mysql://localhost:3306/xdb?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT
  redis:
    port: 6379
    host: localhost

logging:
  level:
    com.zhu: debug

2、Mybatis-plus代码生成

1.编写代码生成器

package com.zhu;

import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

import java.util.Collections;

public class CodeGenerator {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/xdb?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT";
        String username = "root";
        String password = "123456";
        String moduleName = "sys";
        String mapperLocation = "E:\\Intellij IDEA\\项目\\x-admin\\src\\main\\resources\\mapper\\"+ moduleName;
        String tables = "x_user,x_menu,x_role,x_role_menu,x_user_role";
        FastAutoGenerator.create(url, username, password)
                .globalConfig(builder -> {
                    builder.author("zhutieyang") // 设置作者
                            //.enableSwagger() // 开启 swagger 模式
                            .fileOverride() // 覆盖已生成文件
                            .outputDir("E:\\Intellij IDEA\\项目\\x-admin\\src\\main\\java"); // 指定输出目录
                })
                .packageConfig(builder -> {
                    builder.parent("com.zhu") // 设置父包名
                            .moduleName(moduleName) // 设置父包模块名
                            .pathInfo(Collections.singletonMap(OutputFile.xml, mapperLocation)); // 设置mapperXml生成路径
                })
                .strategyConfig(builder -> {
                    builder.addInclude(tables) // 设置需要生成的表名
                            .addTablePrefix("x_"); // 设置过滤表前缀
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
}

2、启动类加注解

因为自动生成的时候没有@mapper

3、测试

3、公共响应类

package com.zhu.common;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Result<T> {
    private Integer code;
    private String message;
    private T  data;

    public static <T> Result<T> success(){
        return new Result<>(20000,"success",null);
    }

    public static <T> Result<T> success(T data){
        return new Result<>(20000,"success",data);
    }

    public static <T> Result<T> success(T data,String message){
        return new Result<>(20000,message,data);
    }

    public static <T> Result<T> success(String message){
        return new Result<>(20000,message,null);
    }
    public static<T>  Result<T> fail(){
        return new Result<>(20001,"fail",null);
    }

    public static<T>  Result<T> fail(Integer code){
        return new Result<>(code,"fail",null);
    }

    public static<T>  Result<T> fail(Integer code, String message){
        return new Result<>(code,message,null);
    }

    public static<T>  Result<T> fail( String message){
        return new Result<>(20001,message,null);
    }

}


4.登录相关接口

4.1、登录

controller

@PostMapping("/login")
    public Result<Map<String,Object>> login(@RequestBody User user){

        Map<String,Object>  data = userService.login(user);
        if(data !=null){
            return Result.success(data);
        }

        return Result.fail(20002,"用户名或密码错误");

    }

service

package com.zhu.sys.service.impl;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.zhu.config.MyRedisConfig;
import com.zhu.sys.entity.User;
import com.zhu.sys.mapper.UserMapper;
import com.zhu.sys.service.IUserService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.omg.CORBA.TIMEOUT;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

import java.util.HashMap;
import java.util.Map;
import java.util.UUID;
import java.util.concurrent.TimeUnit;

/**
 * <p>
 *  服务实现类
 * </p>
 *
 * @author zhutieyang
 * @since 2024-04-06
 */
@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService {

    @Autowired
    private RedisTemplate redisTemplate;


    @Override
    public Map<String, Object> login(User user) {
        // 根据用户名和密码去查询
        LambdaQueryWrapper<User> wrapper = new LambdaQueryWrapper<>();
        wrapper.eq(User::getUsername,user.getUsername());
        wrapper.eq(User::getPassword,user.getPassword());
        User loginUser = this.baseMapper.selectOne(wrapper);

        // 结果不为空，则生成token,并将用户信息存入redis
        if(loginUser !=null){
            // 暂时用UUID,终极方案是jwt
           String key ="user:"+ UUID.randomUUID();

           // 存入redis
            loginUser.setPassword(null);
            redisTemplate.opsForValue().set(key,loginUser,30, TimeUnit.MINUTES);

            // 返回数据
            Map<String, Object> data = new HashMap<>();
            data.put("token",key);
            return data;
        }


        return null;
    }
}

4.1.2、整合redis

1.pom

<!-- redis -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2.yml

spring:
  redis:
    host: localhost
    port: 6379

3.配置类

package com.zhu.config;


import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonTypeInfo;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.MapperFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.jsontype.impl.LaissezFaireSubTypeValidator;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.stereotype.Controller;

import javax.annotation.Resource;
import java.text.SimpleDateFormat;
import java.util.TimeZone;

@Configuration
public class MyRedisConfig {

    @Resource
    private RedisConnectionFactory factory;

    @Bean
    public RedisTemplate redisTemplate(){
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);

        redisTemplate.setKeySerializer(new StringRedisSerializer());

        Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer<Object>(Object.class);
        redisTemplate.setValueSerializer(serializer);

        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
        om.setTimeZone(TimeZone.getDefault());
        om.configure(MapperFeature.USE_ANNOTATIONS, false);
        om.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        om.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
        om.activateDefaultTyping(LaissezFaireSubTypeValidator.instance ,ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
        om.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        serializer.setObjectMapper(om);



        return redisTemplate;
    }
}

4.2、获取用户信息

controller

@GetMapping("/info")
    public Result<?> getUserInfo(@Param("token") String token){
        Map<String,Object> data = userService.getUserInfo(token);
        if(data != null){
            return Result.success(data);
        }
        return Result.fail(20003,"用户信息获取失败");
    }

service

public Map<String, Object> getUserInfo(String token) {
    // 从redis查询token
    Object obj = redisTemplate.opsForValue().get(token);
    // 反序列化
    User user = JSON.parseObject(JSON.toJSONString(obj),User.class);
    if(user != null){
        Map<String, Object> data =  new HashMap<>();
        data.put("name",user.getUsername());
        data.put("avatar",user.getAvatar());
        List<String> roleList = this.getBaseMapper().getRoleNamesByUserId(user.getId());
        data.put("roles", roleList);
        return data;
    }
    return null;
}

mapper.xml

<select id="getRoleNamesByUserId" parameterType="Integer" resultType="String">
    SELECT
    b.role_name
    FROM x_user_role a,x_role b
    WHERE a.`user_id` = #{userId}
    AND a.`role_id` = b.`role_id`
</select>

4.3、注销

controller

@PostMapping("/logout")
public Result<?> logout(@RequestHeader("X-Token") String token){
    userService.logout(token);
    return Result.success("注销成功");
}

service

public void logout(String token) {
    redisTemplate.delete(token);
}

5、跨域处理

记得打开redis

package com.zhu.config;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@Configuration
public class MyCorsConfig {

    @Bean
    public CorsFilter corsFilter(){
        //添加CORS配置信息
        CorsConfiguration configuration = new CorsConfiguration();
        //允许的域,不要写*，否则cookie就无法使用了
        configuration.addAllowedOrigin("http://localhost:8888");//这里填写请求的前端服务器

        //是否发送Cookie信息
        configuration.setAllowCredentials(true);
        //允许的请求方式
        configuration.addAllowedMethod("*");

        // 4）允许的头信息
        configuration.addAllowedHeader("*");


        // 添加映射路径，我们拦截一切请求
        UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource = new UrlBasedCorsConfigurationSource();
        urlBasedCorsConfigurationSource.registerCorsConfiguration("/**",configuration);

        //返回新的CorsFilter
        return new CorsFilter(urlBasedCorsConfigurationSource);

    }
}

6、用户管理接口

6.1、查询用户列表

1、controller

 @GetMapping("/list")
    public Result<Map<String,Object>> getUserList(@RequestParam(value = "username",required = false) String username,
                                              @RequestParam(value = "phone",required = false) String phone,
                                              @RequestParam(value = "pageNo") Long pageNo,
                                              @RequestParam(value = "pageSize") Long pageSize){

        LambdaQueryWrapper<User> wrapper = new LambdaQueryWrapper<>();
        wrapper.eq(StringUtils.hasLength(username),User::getUsername,username);
        wrapper.eq(StringUtils.hasLength(phone),User::getPhone,phone);

        Page<User> page = new Page<>(pageNo,pageSize);
        userService.page(page,wrapper);

        Map<String,Object> data = new HashMap<>();
        data.put("total",page.getTotal());
        data.put("rows",page.getRecords());

        return Result.success(data);

2、分页拦截器

@Configuration
public class MpConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }
}
