spring boot redis session

1. pom.xml

这里 spring parent的版本 2.1.5会报错 2.1.0和2.1.4经过测试正常

2.config

开启redis session

import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
 
@Configuration
@EnableRedisHttpSession
public class RedisSessionConfig {
}

3. application.yml

spring:
  session:
    store-type: redis
    timeout: 3600s
    redis:
      flush-mode: on_save
      namespace: spring:session
  redis:
    host: localhost
    port:
    timeout: 5000ms

4 测试类

package com.smile.shiroclient.controller;
 
import com.smile.shiroclient.model.User;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
import javax.servlet.http.HttpSession;
import java.util.UUID;
 
@RestController
public class UserController {
 
    @RequestMapping("/getUser")
    @Cacheable(value="user-key")
    public User getUser() {
        User user=new User("aa@126.com", "aa", "aa123456", "aa","123");
        System.out.println("若下面没出现“无缓存的时候调用”字样且能打印出数据表示测试成功");
        return user;
    }
 
    @RequestMapping("/uid")
    String uid(HttpSession session) {
        UUID uid = (UUID) session.getAttribute("uid");
        if (uid == null) {
            uid = UUID.randomUUID();
        }
        session.setAttribute("uid", uid);
        return session.getId();
    }
}

到这里session 已经存到redis中, user 还未放入redis

5. 开启查询缓存(将user放入redis)

import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
import java.lang.reflect.Method;
 
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport{
 
    @Bean
    public KeyGenerator keyGenerator() {
        return new KeyGenerator() {
            @Override
            public Object generate(Object target, Method method, Object... params) {
                StringBuilder sb = new StringBuilder();
                sb.append(target.getClass().getName());
                sb.append(method.getName());
                for (Object obj : params) {
                    sb.append(obj.toString());
                }
                return sb.toString();
            }
        };
    }
}
