集成sprnigboot

pom

<!-- https://mvnrepository.com/artifact/net.spy/spymemcached -->
<dependency>

application.properties

memcache.ip=127.0.0.1
memcache.port=11211

添加一个MemcacheConfig配置类读取主机端口并构造一个MemcachedClient。

import java.io.IOException;
import java.net.InetSocketAddress;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import net.spy.memcached.MemcachedClient;

@Configuration
public class MemcacheConfig {

    @Value("${memcache.ip}")
    private String ip;

    @Value("${memcache.port}")
    private int port;


    @Bean
    public MemcachedClient getClient() {
        MemcachedClient memcachedClient = null;
        try {
            memcachedClient  = new MemcachedClient(new InetSocketAddress(ip, port));
        } catch (IOException e) {
            e.printStackTrace();
        }
        return memcachedClient;
    }
}

编写一个业务控制器，通过MemcachedClient实现对缓存的设置和读取。

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import net.spy.memcached.MemcachedClient;
import net.spy.memcached.internal.OperationFuture;


@RestController
public class MemcacheController {
    private Logger logger = LoggerFactory.getLogger(getClass());
    @Autowired
    private MemcachedClient memcachedClient;

    @GetMapping("/info")
    public String memcacheGetValue() throws InterruptedException {
        // 取出缓存
        Object value = memcachedClient.get("userName");
        logger.info("取出缓存 "+value);
        return "取出的值  "+value;
    }

    @GetMapping("/save")
    public String saveValue(@RequestParam String userName) throws InterruptedException {
        // 放入缓存, 过期时间为5000，单位为毫秒
        OperationFuture<Boolean> flag = memcachedClient.set("userName", 5000, userName);
        return "保存成功";
    }
}
