環(huán)境信息

-購買操作系統(tǒng)選擇centos7（7的任何一個(gè)版本都可以）括饶，如果選錯(cuò)了可以在阿里云管理面板的-更多--云盤和鏡像--更換操作系統(tǒng)株茶。

在阿里云購買ecs-購買后機(jī)器網(wǎng)卡環(huán)境：
公網(wǎng)IP-8.134.80.143、內(nèi)網(wǎng)IP-172.30.40.95

設(shè)置阿里云端口映射：

開放1個(gè)端口
11211：memcached調(diào)用端口
配置入口-->安全組-->配置規(guī)則
點(diǎn)擊手動(dòng)添加图焰，添加11211端口

開始安裝

memcached 安裝比較簡單启盛，直接yum安裝完成。

yum -y install memcached

啟動(dòng)memcached

(停止直接kill掉進(jìn)程)

memcached -d -u root -l 0.0.0.0 -p 11211 -m 128

SpringBoot接入調(diào)用

引用

pom文件引入

<!--memcached-->
      <dependency>
            <groupId>com.googlecode.xmemcached</groupId>
            <artifactId>xmemcached</artifactId>
            <version>2.4.5</version>
        </dependency>

配置文件application.yaml 的memcached參數(shù)

內(nèi)容（8.134.80.143是阿里云公網(wǎng)IP）：

memcache:
  server: 8.134.80.143:11211
  poolSize: 20
  sanitizeKeys: false
  opTimeout: 3000

創(chuàng)建memcached操作和測(cè)試類

屬性類-MemcachedProperties：

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

@Component
@ConfigurationProperties(prefix = "memcache")
public class MemcachedProperties {

    private String server;

    private int poolSize;

    private boolean sanitizeKeys;

    private int opTimeout;

    public String getServer() {
        return server;
    }

    public void setServer(String server) {
        this.server = server;
    }

    public int getPoolSize() {
        return poolSize;
    }

    public void setPoolSize(int poolSize) {
        this.poolSize = poolSize;
    }

    public boolean isSanitizeKeys() {
        return sanitizeKeys;
    }

    public void setSanitizeKeys(boolean sanitizeKeys) {
        this.sanitizeKeys = sanitizeKeys;
    }

    public int getOpTimeout() {
        return opTimeout;
    }

    public void setOpTimeout(int opTimeout) {
        this.opTimeout = opTimeout;
    }
}

初始化注入實(shí)現(xiàn)類-MemcacheConfig：

import net.rubyeye.xmemcached.MemcachedClient;
import net.rubyeye.xmemcached.MemcachedClientBuilder;
import net.rubyeye.xmemcached.XMemcachedClientBuilder;
import net.rubyeye.xmemcached.command.BinaryCommandFactory;
import net.rubyeye.xmemcached.impl.KetamaMemcachedSessionLocator;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

@Component
public class MemcacheConfig {
    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private MemcachedProperties memcachedProperties;

    //構(gòu)建builder
    @Bean
    public MemcachedClientBuilder getXMBuilder(){
        MemcachedClientBuilder memcachedClientBuilder = null;
        try {
            String server =memcachedProperties.getServer();
            memcachedClientBuilder= new XMemcachedClientBuilder(server);
            memcachedClientBuilder.setFailureMode(false);
            memcachedClientBuilder.setSanitizeKeys(memcachedProperties.isSanitizeKeys());
            memcachedClientBuilder.setConnectionPoolSize(memcachedProperties.getPoolSize());
            memcachedClientBuilder.setCommandFactory(new BinaryCommandFactory());
            memcachedClientBuilder.setOpTimeout(memcachedProperties.getOpTimeout());
            memcachedClientBuilder.setSessionLocator(new KetamaMemcachedSessionLocator());
            return  memcachedClientBuilder;
        }catch (Exception e){
            e.printStackTrace();
        }
        return null;
    }

    @Bean
    public MemcachedClient getXMClient(MemcachedClientBuilder builder){
        MemcachedClient client = null;
        try {
            client = builder.build();
            logger.info("MemcachedClient 創(chuàng)建成功 ");
            return client;
        }catch (Exception e){
            e.printStackTrace();
        }
        return null;
    }


}

memcached的controller測(cè)試類-MemcacheController：

import lombok.extern.slf4j.Slf4j;
import net.rubyeye.xmemcached.MemcachedClient;
import net.rubyeye.xmemcached.exception.MemcachedException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.concurrent.TimeoutException;

@Slf4j
@RestController
public class MemcacheController {

    @Autowired
    private MemcachedClient memCachedClient;

    private int cacheTime = 3600*4 ;
    @RequestMapping("cacheSend")
    public String send(String key,String info){
        log.info(info);
        try {
            memCachedClient.set(key, cacheTime, info);
        } catch (TimeoutException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (MemcachedException e) {
            e.printStackTrace();
        }
        return "cache成功";
    }

    @RequestMapping("cacheGet")
    public String get(String key){
        String info = "";
        try {
             info = memCachedClient.get(key);
        } catch (TimeoutException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (MemcachedException e) {
            e.printStackTrace();
        }
        return info;
    }
}
