问题：

使用分布式terracotta ehcache运行spring boot代码时出现异常

庄高谊
2023-03-14

我已经创建了一个使用分布式ehcache的spring boot项目。我下载并运行terracotta服务器，配置在tc-config.xml中。服务器在本地主机9510上成功运行。以下是我的ehcache。xml，它位于spring boot项目的类路径中

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="ehcache.xsd">
    <terracottaConfig url="localhost:9510"/>
    <cache name="ticketsCache" maxEntriesLocalHeap="1000">
        <terracotta consistency="eventual"/>
    </cache>
</ehcache>

以下是我的maven依赖。

下面是我尝试创建缓存管理器的代码，以便在我的应用程序中使用它

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.CacheManager;
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.core.io.ClassPathResource;

@SpringBootApplication
@EnableCaching
public class TicketBookingManagementApplication {

    public TicketBookingManagementApplication() {

    }
    @Bean
    public CacheManager cacheManager() {
        return new EhCacheCacheManager(ehCacheCacheManager().getObject());
    }
     @Bean
        public EhCacheManagerFactoryBean ehCacheCacheManager() {
            EhCacheManagerFactoryBean cmfb = new EhCacheManagerFactoryBean();
            cmfb.setConfigLocation(new ClassPathResource("ehcache.xml"));
            cmfb.setShared(true);
            return cmfb;
        }
    public static void main(String[] args) {
        SpringApplication.run(TicketBookingManagementApplication.class, args);
    }

}

但我得到的例外如下

在你的pom中使用下面的maven依赖性.xml

 <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>4.3.4.RELEASE</version>
    </dependency>

另外，请确保您使用版本4.3.4。不要使用5.0.6它对我不起作用。

您的版本不匹配：

  • 您的XML和Spring集成与Ehache2. x相关
  • 您的Ehcache依赖项是Ehcache 3. x坐标

您需要选择一个，因为Ehcache 2和3互不兼容。

如果你想使用埃卡什 2.x，请注释掉埃卡什 3 的依赖项，并使用埃卡什 2 的依赖项。

如果您想使用Ehcache3.x，请将SpringEhcache集成替换为SpringJCache集成，并更新XML以使用EhcCache3格式。
