springboot集成redis

首先引入依赖

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

在yml中引入redis数据库

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/big_event
    username: root
    password: 1234
  data:
    redis:
      host: localhost
      port: 6379


mybatis:
  configuration:
    map-underscore-to-camel-case: true #开启下划线驼峰命名之间的转换

测试代码

package com.di.bigevent;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;

import java.util.concurrent.TimeUnit;

@SpringBootTest//如果在这个测试类上添加了这个注解，那么将来单元测试方法执行前，会先初始化spring容器
public class RedisTest {


    @Autowired
    private StringRedisTemplate stringRedisTemplate;
    @Test
    public void testSet(){

        //往redis中存储一个键值对 StringRedisTemplate
        ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
        operations.set("username","zhangsan");
        operations.set("id","1",15, TimeUnit.SECONDS);
    }

    @Test
    public void testGet(){
        //从redis中获取键值对
        ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
        System.out.println(operations.get("username"));
    }
}

令牌主动失效

• 把令牌存到redis中
• 拦截器Intercepter中，同时验证自带的token和redis中的taken

首先在usercontroller中

 @Autowired
    private StringRedisTemplate stringRedisTemplate;

//把token存到redis中
            ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
            operations.set(token,token,1, TimeUnit.HOURS);

从拦截器中添加验证redis中token的步骤

@Autowired
    private StringRedisTemplate stringRedisTemplate;


//从redis中获取相同的token
            ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
            String redisToken = operations.get(token);
            if(redisToken==null)
            {
                //token已经失效了
                throw new RuntimeException();
            }

在修改密码的controller中，添加参数

@RequestHeader("Authorization") String token

修改密码后，删除redis中的token

//删除redis中对应的token
        ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
        operations.getOperations().delete(token);
