在单元测试中遇到静态类和方法时，EasyMock无法处理。本文介绍了如何利用PowerMock进行模拟，首先在pom.xml添加PowerMock依赖，然后展示了调用memecached服务器静态方法的场景，接着描述了一个使用了该静态方法的类，最后说明如何通过PowerMock为这个类的单元测试模拟静态方法。

在写单元测试时总会碰到一些静态类和静态方法，EasyMock无法处理这些方法，所以我们需要使用PowerMock。

1、在pom.xml中添加powermock的依赖

<dependency>
	<groupId>org.powermock</groupId>
	<artifactId>powermock-api-easymock</artifactId>
	<version>1.5.1</version>
	<scope>test</scope>
</dependency>
<dependency>
	<groupId>org.powermock</groupId>
	<artifactId>powermock-module-junit4</artifactId>
	<version>1.5.1</version>
	<scope>test</scope>
</dependency>

2、访问memecached服务器的静态方法类

package com.example.common;

import java.io.IOException;
import java.util.concurrent.TimeoutException;

import net.rubyeye.xmemcached.MemcachedClient;
import net.rubyeye.xmemcached.MemcachedClientBuilder;
import net.rubyeye.xmemcached.XMemcachedClientBuilder;
import net.rubyeye.xmemcached.exception.MemcachedException;
import net.rubyeye.xmemcached.utils.AddrUtil;

public class XMemcacheClient {

    protected static MemcachedClient connectMem() throws IOException {
        String memURL = SysProperties.MEMCACHED_SERVER + ":" + SysProperties.MEMCACHED_PORT;
        MemcachedClientBuilder builder = new XMemcachedClientBuilder(AddrUtil.getAddresses(memURL));
        MemcachedClient memcachedClient = builder.build();
        return memcachedClient;
    }

    protected static void close(MemcachedClient memcachedClient) throws IOException {
        if (memcachedClient != null) {
            memcachedClient.shutdown();
        }
    }

    public static boolean set(String key, int exp, Object o) throws IOException, TimeoutException, InterruptedException, MemcachedException {
        MemcachedClient memcachedClient = null;
        try {
            memcachedClient = connectMem();
            return memcachedClient.set(key, exp, o);
        } finally {
            close(memcachedClient);
        }
    }

    public static Object get(String key) throws IOException, TimeoutException, InterruptedException, MemcachedException {
        MemcachedClient memcachedCl
