springboot中自己封装jedisUtil (原创)

springboot中自己封装jedisUtil ，操作redis

1、pom.xml引入

<dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>3.1.0</version>
    </dependency>

2、JedisProperties属性类

@Getter
@Setter
public class JedisProperties {

    private String address="redis://localhost:6379/0";

    private int  maxTotal =20;
    private int  maxIdle=5 ;
    private int  minIdle=5 ;
    private long  maxWailMillis=10000L ;
    private boolean  testOnBorrow=false;
    private boolean  testOnReturn=false;

}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
@EnableConfigurationProperties(JedisProperties.class)
public class JedisConfig {
    @Autowired
    private JedisProperties jedisProperties;

    @Bean
    public JedisUtil jedisUtil(){
        JedisUtil jedisUtil=new JedisUtil();
        jedisUtil.setJedisProperties(jedisProperties);
        return jedisUtil;
    }

}

4、JedisUtil 工具bean

import lombok.Getter;
import lombok.Setter;
import lombok.extern.slf4j.Slf4j;
import redis.clients.jedis.JedisPoolConfig;
import redis.clients.jedis.JedisShardInfo;
import redis.clients.jedis.ShardedJedis;
import redis.clients.jedis.ShardedJedisPool;

import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import java.io.*;
import java.util.LinkedList;
import java.util.List;


@Slf4j
public class JedisUtil {

    @Getter
    @Setter  //spring容器注入
    private JedisProperties jedisProperties;

    //内部初始化
    private ShardedJedisPool shardedJedisPool;

    @PostConstruct
    public void  init(){
        JedisPoolConfig config = new JedisPoolConfig();

        config.setMaxTotal(jedisProperties.getMaxTotal());
        config.setMaxIdle(jedisProperties.getMaxIdle());
        config.setMinIdle(jedisProperties.getMinIdle());
        config.setMaxWaitMillis(jedisProperties.getMaxWailMillis());
        config.setTestOnBorrow(jedisProperties.isTestOnBorrow());
        config.setTestOnReturn(jedisProperties.isTestOnReturn());

        // JedisShardInfo List
        String address  =jedisProperties.getAddress();
        List<JedisShardInfo> jedisShardInfos = new LinkedList<JedisShardInfo>();
        String[] addressArr = address.split(",");
        for (String addr: addressArr) {
            JedisShardInfo sharedInfo = new JedisShardInfo(addr);

            jedisShardInfos.add(sharedInfo);
        }

        shardedJedisPool = new ShardedJedisPool(config, jedisShardInfos);
    }

    @PreDestroy
    public void destroy(){
        if(shardedJedisPool!=null){
            shardedJedisPool.close();
        }
    }

    private ShardedJedis  getInstance(){
        return shardedJedisPool.getResource();
    }

5、springboot测试类 

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

    @Autowired
    private JedisUtil jedisUtil;

    @Test
    public void test1(){
        jedisUtil.setStringValueEx("key1","helloworld",3600);
        String value =jedisUtil.getStringValue("key1");
        System.out.println(value);
    }
    @Test
    public void test2(){
        User user=new User();
        user.setId(1);
        user.setBirthday("1999-09-09");
        user.setName("张三");
        user.setSex(1);
        user.setRemark("备注");

        jedisUtil.setObjectValueEx("zhangsan",user,3600);

        User zs=(User) jedisUtil.getObjectValue("zhangsan");
        System.out.println(zs);

    }
}
