memcached的简单使用

因工作项目本身就安装了memcached，需要安装的请自行百度

需要额外引入的依赖

<dependency>
<groupId>net.spy</groupId>
<artifactId>spymemcached</artifactId>
<version>2.12.2</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>

1.启动类

package com.memcached.test;

import java.io.IOException;
import java.net.InetSocketAddress;

import javax.annotation.Resource;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.memcached.test.Demo.MemcacheSource;

import net.spy.memcached.MemcachedClient;

@SpringBootApplication
public class MemcacheApplication implements CommandLineRunner{
    @Resource
    private  MemcacheSource memcacheSource;

    private MemcachedClient client = null;
    public static void main(String[] args) {
        SpringApplication.run(MemcacheApplication.class, args);
    }

    @Override
    public void run(String... args) throws Exception {
        try {
            client = new MemcachedClient(new InetSocketAddress(memcacheSource.getIp(),memcacheSource.getPort()));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public MemcachedClient getClient() {
        return client;
    }
    
}

2.加载ip端口

package com.memcached.test.Demo;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "memcache")//意思会以 memcache.* 为开通将对应的配置文件加载到属性中
public class MemcacheSource {

    private String ip;

    private int port;

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }
}

3.测试memcached的启动类

package com.memcached.test;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import net.spy.memcached.MemcachedClient;

@RunWith(SpringRunner.class)
@SpringBootTest
public class MemcacheApplicationTests {
    @Resource
    public MemcacheApplication memcachedRunner;

    @Test
    public void testSetGet()  {
    MemcachedClient memcachedClient = memcachedRunner.getClient();
    memcachedClient.set("asd",1000,"123");
    System.out.println(""+memcachedClient.get("asd").toString());
  } 

}

resources下建一个application.properties

#缓存配置

memcache.ip=127.0.0.1

memcache.port=11211

配置类会自行读取该配置
