**1.pom.xml配置依赖包**

<dependency>
        <groupId>net.sf.ehcache</groupId>
        <artifactId>ehcache</artifactId>
        <version>2.8.3</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
    </dependency>

**2.在resources根目录下添加ehcache.xml配置文件**

<?xml version="1.0" encoding="UTF-8"?>
    <ehcache>
          
        <diskStore path="java.io.tmpdir" />
        
        <defaultCache maxElementsInMemory="500" eternal="false" timeToIdleSeconds="300" timeToLiveSeconds="1200"  overflowToDisk="true" />
        
        <cache name="cachePool" maxElementsInMemory="10000" eternal="false" timeToLiveSeconds="36000"  timeToIdleSeconds="3600" overflowToDisk="false" />
    </ehcache>

**3.配置缓存管理器**

import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.cache.ehcache.EhCacheCacheManager;
    import org.springframework.cache.ehcache.EhCacheManagerFactoryBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.core.io.ClassPathResource;
    
    @Configuration
    @EnableCaching//标注启动缓存
    public class CacheConfig {
    	
        @Bean
        public EhCacheCacheManager ehCacheCacheManager(EhCacheManagerFactoryBean bean){
            return new EhCacheCacheManager (bean.getObject());
        }
    
        @Bean
        public EhCacheManagerFactoryBean ehCacheManagerFactoryBean(){
            EhCacheManagerFactoryBean cacheManagerFactoryBean = new EhCacheManagerFactoryBean();
            cacheManagerFactoryBean.setConfigLocation (new ClassPathResource ("ehcache.xml"));
            cacheManagerFactoryBean.setShared (true);
            return cacheManagerFactoryBean;
        }
    }

**4.测试**

import net.sf.ehcache.Cache;
    import net.sf.ehcache.CacheManager;
    import net.sf.ehcache.Element;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class TestController {
    	
    	@Autowired
    	private CacheManager cacheManager;
    
    	@RequestMapping("/test")
    	public void test(Model model) {
    		Cache cache = cacheManager.getCache("cachePool");
    		//添加缓存
    		Element element = new Element("xm", "测试"); 
    		cache.put(element);
    		//查询缓存
    		element = cache.get("xm");  
    		System.out.println("查询缓存："+(element == null ? null : element.getObjectValue()));
    		//移除缓存
    		cache.remove("xm"); 
    		element = cache.get("xm");  
    		System.out.println("移除缓存："+(element == null ? null : element.getObjectValue()));
    	}
    	
    }
