Spring Cloud整合Redis

项目需要使用Redis来做缓存,研究了一下如何将其与Spring Boot整合。网上的demo要么就是太过于庞大,要么就是版本过于陈旧,配置时候会有各种坑。因此自己在踩过了各种坑之后,写一个小demo来记录下:

1.项目结构:

2.pom的依赖配置:

本人使用的Spring Boot是2.0.4.RELEASE版本的:

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

添加redis的依赖:

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

添加common-pool2的依赖:

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
            <version>2.0</version>
        </dependency>

我在这里尝试过不加version,让springboot自己选择最合适的版本,结果会报错。参考别人的例子,选择2.0版本,没有问题。

3.修改application.yml:

这里的host填写自己redis的IP,timeout别设置为0,否则运行会报错

spring:
  redis:
    host: 
    port: 6379
    lettuce:
      pool:
        max-wait: 100000
        max-idle: 10
        max-active: 100
    timeout: 5000

3.编写dao层:

package com.hg.redis;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Repository;

import java.util.concurrent.TimeUnit;

/**

 */
@Repository
public class RedisDao {
    @Autowired
    private StringRedisTemplate template;

    public void setKey(String key, String value) {
        ValueOperations<String, String> ops = template.opsForValue();
        ops.set(key, value);
    }

    public String getValue(String key) {
        ValueOperations<String, String> ops = this.template.opsForValue();
        return ops.get(key);
    }
}

4.修改测试启动类:

package com.hg.redis;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisApplicationTests {

	@Test
	public void contextLoads() {
	}

}

5.编写一个测试类:

package com.hg.redis;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;


/**
 * @Description:
 * @Author: jiangfan
 * @CreateTime 2018/9/27 上午10:26
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootRedisApplicationTests {
    public static Logger logger = LoggerFactory.getLogger(SpringbootRedisApplicationTests.class);

    @Test
    public void contextLoads(){}

    @Autowired
    RedisDao redisDao;

    @Test
    public void testRedis() {
        redisDao.setKey("name","jerry");
        redisDao.setKey("age","11");
        logger.info(redisDao.getValue("name"));
        logger.info(redisDao.getValue("age"));
    }
}

6.运行测试类:
