Spring Boot集成Redis

这是一个Springboot项目中整合Redis的示例。

1.引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
</dependency>

2.Spring配置文件

application.yml内容如下：

spring:
  redis:
    host: 178.128.150.98 # Redis服务器地址
    database: 0 # Redis数据库索引（默认为0）
    port: 6379 # Redis服务器连接端口
    password: 4spaces.org # Redis服务器连接密码（默认为空）
    timeout: 1000ms # 连接超时时间
    lettuce:
      pool:
        max-active: 8
        max-wait: -1
        max-idle: 8
        min-idle: 0

3.新建配置类

package com.ddmit.redis.config;

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();
            }
        };
    }
}

4.Springboot单元测试

package com.ddmit.redis;

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.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;

import javax.annotation.Resource;

@SpringBootTest
class RedisApplicationTests {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    @Autowired
    private RedisTemplate redisTemplate;

    @Resource(name = "stringRedisTemplate")
    private ValueOperations<String, String> sops;

    @Test
    public void test() throws Exception {
        stringRedisTemplate.opsForValue().set("aaa", "111");
        System.out.println(stringRedisTemplate.opsForValue().get("aaa"));
        System.out.println(sops.get("aaa"));
    }
}
