1、创建项目，导入Jar包
2、直接上代码，注释很详细（SET操作）
package com.jiayuan.memcacheTest;
import java.net.InetSocketAddress;
import java.util.concurrent.Future;
import net.spy.memcached.MemcachedClient;
public class MemcacheTest {
@SuppressWarnings("rawtypes")
public static void main(String[] args) {
try{
// 本地连接 Memcached 服务
MemcachedClient mcc = new MemcachedClient(new InetSocketAddress("127.0.0.1", 11211));
System.out.println("Connection to server sucessful.");
// 存储数据
Future fo = mcc.set("Wenhy", 900, "Free Education");
// 查看存储状态
System.out.println("set status:" + fo.get());
// 输出值
System.out.println("wenhy value in cache - " + mcc.get("Wenhy"));
// 关闭连接
mcc.shutdown();
}catch(Exception ex){
System.out.println( ex.getMessage() );
}
}
}
3、Add操作
@SuppressWarnings("rawtypes")
private static void addMemcache(MemcachedClient mcc) throws Exception {
// 添加数据
Future fo = mcc.set("Wenhy", 900, "Free Education");
// 打印状态
System.out.println("set status:" + fo.get());
// 输出
System.out.println("wenhy value in cache - " + mcc.get("Wenhy"));
// 添加
Future fo1 = mcc.add("Wenhy", 900, "memcached");
// 打印状态
System.out.println("add status:" + fo1.get());
// 添加新key
Future fo2 = mcc.add("Wenhy123", 900, "All Free Compilers");
// 打印状态
System.out.println("add status:" + fo2.get());
// 输出
System.out.println("Wenhy123 value in cache - " + mcc.get("Wenhy123"));
// 关闭连接
mcc.shutdown();
}
public static void main(String[] args) {
try{
// 本地连接 Memcached 服务
MemcachedClient mcc = new MemcachedClient(new InetSocketAddress("127.0.0.1", 11211));
System.out.println("Connection to server sucessful.");
//SET操作
//MemcacheTest.setMemcache(mcc);
//Add操作
MemcacheTest.addMemcache(mcc);
}catch(Exception ex){
System.out.println( ex.getMessage() );
}
}
4、replace 操作实例
@SuppressWarnings("rawtypes")
private static void replaceMemcache(MemcachedClient mcc) throws Exception {
// 添加第一个 key=》value 对
Future fo = mcc.set("Wenhy", 900, "Free Education");
// 输出执行 add 方法后的状态
System.out.println("add status:" + fo.get());
// 获取键对应的值
System.out.println("Wenhy value in cache - " + mcc.get("Wenhy"));
// 添加新的 key
fo = mcc.replace("Wenhy", 900, "Largest Tutorials' Library");
// 输出执行 replace 方法后的状态
System.out.println("replace status:" + fo.get());
// 获取键对应的值
System.out.println("Wenhy value in cache - " + mcc.get("Wenhy"));
// 关闭连接
mcc.shutdown();
}
public static void main(String[] args) {
try{
// 本地连接 Memcached 服务
MemcachedClient mcc = new MemcachedClient(new InetSocketAddress("127.0.0.1", 11211));
System.out.println("Connection to server sucessful.");
//SET操作
//MemcacheTest.setMemcache(mcc);
//Add操作
//MemcacheTest.addMemcache(mcc);
//replace 操作实例
MemcacheTest.replaceMemcache(mcc);
}catch(Exception ex){
System.out.println( ex.getMessage() );
}
}
5、append 操作实例
@SuppressWarnings("rawtypes")
private static void appendMemcache(MemcachedClient mcc) throws Exception {
// 添加数据
Future fo = mcc.set("Wenhy", 900, "Free Education");
// 输出执行 set 方法后的状态
System.out.println("set status:" + fo.get());
// 获取键对应的值
System.out.println("Wenhy value in cache - " + mcc.get("Wenhy"));
// 对存在的key进行数据添加操作
Future fo1 = mcc.append(900, "Wenhy", " for All");
// 输出执行 set 方法后的状态
System.out.println("append status:" + fo1.get());
// 获取键对应的值
System.out.println("Wenhy value in cache - " + mcc.get("Wenhy"));
// 关闭连接
mcc.shutdown();
}
public static void main(String[] args) {
try{
// 本地连接 Memcached 服务
MemcachedClient mcc = new MemcachedClient(new InetSocketAddress("127.0.0.1", 11211));
System.out.println("Connection to server sucessful.");
//SET操作
//MemcacheTest.setMemcache(mcc);
//Add操作
//MemcacheTest.addMemcache(mcc);
//replace 操作实例
//MemcacheTest.replaceMemcache(mcc);
//append 操作实例
MemcacheTest.appendMemcache(mcc);
}catch(Exception ex){
System.out.println( ex.getMessage() );
}
}
结果：
1 set status:true
2 Wenhy value in cache - Free Education
3 append status:true
4 Wenhy value in cache - Free Education for All
备注： prepend 操作实例不做介绍，和append相反，在前面追加
7、delete 操作实例
@SuppressWarnings("rawtypes")
private static void deleteMemcache(MemcachedClient mcc) throws Exception {
// 添加数据
Future fo = mcc.set("Wenhy", 900, "World's largest online tutorials library");
// 输出执行 set 方法后的状态
System.out.println("set status:" + fo.get());
// 获取键对应的值
System.out.println("Wenhy value in cache - " + mcc.get("Wenhy"));
// 对存在的key进行数据添加操作
Future fo1 = mcc.delete("Wenhy");
// 输出执行 delete 方法后的状态
System.out.println("delete status:" + fo1.get());
// 获取键对应的值
System.out.println("Wenhy value in cache - " + mcc.get("Wenhy"));
// 关闭连接
mcc.shutdown();
}
public static void main(String[] args) {
try{
// 本地连接 Memcached 服务
MemcachedClient mcc = new MemcachedClient(new InetSocketAddress("127.0.0.1", 11211));
System.out.println("Connection to server sucessful.");
//SET操作
//MemcacheTest.setMemcache(mcc);
//Add操作
//MemcacheTest.addMemcache(mcc);
//replace 操作实例
//MemcacheTest.replaceMemcache(mcc);
//append 操作实例
//MemcacheTest.appendMemcache(mcc);
//delete操作
MemcacheTest.deleteMemcache(mcc);
}catch(Exception ex){
System.out.println( ex.getMessage() );
}
}
结果：
1 set status:true 2 Wenhy value in cache - World's largest online tutorials library 3 delete status:true 4 Wenhy value in cache - null
总结：以上就是Memcache与java之间调用的全部内容，Java 连接 Memcached 服务比较简单，主要熟悉使用增加、追加、替换、删除等操作。
