我正在将我们现有的spring boot 1.5应用升级到Spring boot 2.0。该应用程序还利用了Spring Integration xmls。Ehcache组件在尝试执行此操作时出现问题。当尝试将GET调用的响应添加到缓存时，它抛出了一个异常：

路径为[]的上下文中servlet dispatcherServlet的

Servlet.service()引发异常[请求处理失败；嵌套异常是消息处理程序中出现org.springframework.messaging.MessageHandlingException:错误；嵌套异常是net.sf.ehcache.CacheException:当配置copyOnRead或copyOnWrite时，存储区将只接受可序列化的值、failedMessage=GenericMessage payload={}、headers={http_requestMethod=GET .....]有根本原因

org.springframework.integration.support.MessageBuilder :java.io.NotSerializableException

在Spring Boot1.5中，它工作得很好，插入到缓存中的值(XML Response)是GenericMessage类型的。下面是整个堆栈跟踪：

我是否需要显式强制转换响应才能使其正常工作？

我拥有的CacheInterceptor实现：

代码语言：javascript
复制
    private MethodInterceptor createGatewayInterceptor(String cacheName) {
    CacheInterceptor interceptor = new CacheInterceptor();
    interceptor.setCacheManager(cacheManager());
    NameMatchCacheOperationSource source = new NameMatchCacheOperationSource();
    CacheableOperation.Builder operationBuilder = new CacheableOperation.Builder();
    operationBuilder.setCacheName(cacheName);
    source.addCacheMethod("handle*Message", Collections.singleton(operationBuilder.build()));
    interceptor.setCacheOperationSources(source);
    interceptor.setKeyGenerator((target, method, params) -> ((Message) params[0]).getHeaders().get(HEADER_CACHEKEY));
    return interceptor;
}

DSL缓存实现：

代码语言：javascript
复制
    adviceChain.add(eternalCacheAdvice);
    adviceChain.add(genericMessageAdvice);
    handler.setAdviceChain(adviceChain);
    return handler;

@Bean
public MethodInterceptor cacheAdvice() {
    return createGatewayInterceptor(TWENTY_FOUR_HOUR_CACHE);
}

@Bean
public MethodInterceptor eternalCacheAdvice() {
    return createGatewayInterceptor(ETERNAL_CACHE);
}

@Bean
public MethodInterceptor genericMessageAdvice(){
    return invocation -> ((MessageBuilder<?>) invocation.proceed()).build();
}
@Bean
public MethodInterceptor genericXMLMessageAdvice(){
    return invocation -> ((MessageBuilder<?>) invocation.proceed()).build();
}

XML通知链：

代码语言：javascript
复制
        <int-http:request-handler-advice-chain>
            <ref bean="genericXMLMessageAdvice" />
            <ref bean="cacheAdvice" />
        </int-http:request-handler-advice-chain>

对于一些内部优化，许多开箱即用的Spring Integration组件现在在生成回复之前返回一个MessageBuilder。这是用额外的报头丰富目标回复消息所必需的。

看起来像是CacheInterceptor执行了invocation.proceed()，广告尝试将结果用于缓存。

考虑在配置的CacheInterceptor之前再添加一个MethodInterceptor，实现方式如下：

代码语言：javascript
复制
invocation -> ((MessageBuilder<?>) invocation.proceed()).build()

因此，您的CacheInterceptor将像以前一样获得预期的GenericMessage<?>。

顺便说一句，我们有一个关于缓存这个caching集成的PR：https://github.com/spring-projects/spring-integration/pull/2105。请随时在那里分享您的经验，这样它可能会推动开箱即用的支持。
