有人用Spring 4.2实现了EhCache 3(不使用Spring启动).如果是这样,实施该步骤的步骤是什么？

问题是spring-context-support(添加了Spring的缓存注释)要求Ehcache的CacheManager在这个类路径上：net.sf.ehcache.CacheManager

但是,在Ehcache 3中,CacheManager类驻留在另一个类路径上：org.ehcache.CacheManager.

因此,基本上spring-context-support不支持Ehcache 3.你必须直接使用JSR-107注释,而不是Spring提供的注释.

如果有人实现了这个组合,请给你ehcache.xml和spring配置以供参考.

解决方法:

Ehcache 3通过JSR-107使用.这是一个例子.

你的pom.xml：

<dependencies>
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>4.2.9.RELEASE</version>
  </dependency>
  <dependency>
    <groupId>org.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>3.5.0</version>
  </dependency>
  <dependency>
    <groupId>javax.cache</groupId>
    <artifactId>cache-api</artifactId>
    <version>1.1.0</version>
  </dependency>

你的ehcache.xml(在类路径的根目录下)：

<?xml version="1.0" encoding="UTF-8"?>
<config
    xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
    xmlns:jsr107='http://www.ehcache.org/v3/jsr107'
    xmlns='http://www.ehcache.org/v3'
    xsi:schemaLocation="
        http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.4.xsd
        http://www.ehcache.org/v3/jsr107 http://www.ehcache.org/schema/ehcache-107-ext-3.4.xsd">

  <service>
    <jsr107:defaults enable-management="false" enable-statistics="true"/>
  </service>

  <cache alias="cache">
    <resources>
      <heap unit="entries">2000</heap>
    </resources>
  </cache>
</config>

使用缓存的示例应用程序：

import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.jcache.JCacheCacheManager;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.net.URISyntaxException;

import javax.cache.Caching;

@EnableCaching
@Configuration
public class App {

    private static int value = 0;

    @Bean
    public CacheManager cacheManager() throws URISyntaxException {
        return new JCacheCacheManager(Caching.getCachingProvider().getCacheManager(
            getClass().getResource("/ehcache.xml").toURI(),
            getClass().getClassLoader()
        ));
    }

    public static void main( String[] args ) {
        ApplicationContext context = new AnnotationConfigApplicationContext(App.class);

        App app = context.getBean(App.class);
        System.out.println(app.incValue());
        System.out.println(app.incValue()); // still return 0
    }

    @Cacheable("cache")
    public int incValue() {
        return value++;
    }

}
