springcontext.xml配置

<!-- 应用spring-cache注解功能 -->
    <cache:annotation-driven cache-manager="cacheManager" />  
    <!-- 配置ehcache管理器-->
    <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">

EhCacheUtils工具类
at com.ssm.common.utils.EhCacheUtils.(EhCacheUtils.java:13)
指
private static CacheManager cacheManager = ((CacheManager)SpringContextHolder.getBean("cacheManager"));

public class EhCacheUtils {

    private static CacheManager cacheManager = ((CacheManager)SpringContextHolder.getBean("cacheManager"));

    private static final String SYS_CACHE = "sysCache";

    public static Object get(String key) {
        return get(SYS_CACHE, key);
    }

    public static void put(String key, Object value) {
        put(SYS_CACHE, key, value);
    }

方法

    @Test
    public void testEhCache(){
        EhCacheUtils.put("user", "张三");     
        System.out.println(EhCacheUtils.get("user"));
    }

pom.xml 包都在

请问解决了吗
