xml：配置缓存名字

    <!--timeToLiveSeconds 当缓存存活n秒后销毁 -->
    <!-- 缓存配置
        name:缓存名称。
        maxElementsInMemory：缓存最大个数。
        eternal:对象是否永久有效，一但设置了，timeout将不起作用。
        timeToIdleSeconds：设置对象在失效前的允许闲置时间（单位：秒）。仅当eternal=false对象不是永久有效时使用，可选属性，默认值是0，也就是可闲置时间无穷大。
        timeToLiveSeconds：设置对象在失效前允许存活时间（单位：秒）。最大时间介于创建时间和失效时间之间。仅当eternal=false对象不是永久有效时使用，默认是0.，也就是对象存活时间无穷大。
        overflowToDisk：当内存中对象数量达到maxElementsInMemory时，Ehcache将会对象写到磁盘中。 diskSpoolBufferSizeMB：这个参数设置DiskStore（磁盘缓存）的缓存区大小。默认是30MB。每个Cache都应该有自己的一个缓冲区。
        maxElementsOnDisk：硬盘最大缓存个数。
        diskPersistent：是否缓存虚拟机重启期数据 Whether the disk
        store persists between restarts of the Virtual Machine. The default value
        is false.
        diskExpiryThreadIntervalSeconds：磁盘失效线程运行时间间隔，默认是120秒。
        memoryStoreEvictionPolicy：当达到maxElementsInMemory限制时，Ehcache将会根据指定的策略去清理内存。默认策略是
LRU（最近最少使用）。你可以设置为FIFO（先进先出）或是LFU（较少使用）。
        clearOnFlush：内存数量最大时是否清除。 -->

3 代码中使用

ps controller层调用方法，如果缓存中查到数据则不进入方法直接返回数据

参考代码

package com.cloud.cloudClient02.Service;

import com.cloud.cloudClient02.controller.CurrentScript;
import org.springframework.cache.annotation.CacheConfig;
import org.springframework.cache.annotation.CacheEvict;
import org.springframework.cache.annotation.CachePut;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Repository;

import java.util.HashMap;
import java.util.Map;

@Repository
@CacheConfig(cacheNames="scripts")
public class CacheDaoImpl {

    @Cacheable(key="#user.getId()")
    public CurrentScript save(CurrentScript user) {
        System.out.println("save()被执行了....");
        return user;
    }



    @Cacheable(key="#userId")
    public CurrentScript select(String userId) {
        System.out.println("select()执行了=============");

         return new CurrentScript();
    }

    /*@CachePut(key="#user.getId()")
    public CurrentScript update(CurrentScript user) {
        System.out.println("update()执行了=============");
        map.put(user.getId(), user);
        return user;
    }

    @CacheEvict(key="#user.getId()")
    public boolean delete(CurrentScript user) {
        System.out.println("delete()执行了=============");
        map.remove(user.getId());
        return true;
    }

    @CacheEvict(allEntries=true,value= {"MyTest","MM"})
    public void deleteAll() {
        map.clear();
    }

    @Cacheable(value="scripts")
    public String selectFromOtherCache() {
        System.out.println("其他缓存");
        return "来自缓存";
    }
*/
   /* @Cacheable(allEntries=true)
    public String selectAll() {

        return
    }*/
}
