使用JBOSS上的apache cxf客户端的Web服务请求(> 8KB)失败 - HTTP响应' 411:需要长度'

Web应用程序正在使用apache cxf客户端向远程Web服务发送请求。

在Tomcat上部署此Web应用程序时,一切正常。

当在JBOSS上部署此Web应用程序并且正文(包络)的大小大于8 KB时,请求无法发送;产生了以下错误:

HTTP流模式似乎已切换为 chunked

  

您如何看待这第一个假设?

可以在官方的apache cxf文档中找到可以提供spring配置文件以更改cxf客户端行为。

  

配置文件内容是什么?

1 个答案:

答案 0 :(得分:1)

  

我回答了我自己的问题,因为经过额外的测试后,下面描述的配置对我有用。

首先,可能是因为cxf客户端自动切换到分块传输模式而产生错误;实际上,此答案中描述的配置更改会强制cxf客户端不使用分块,然后请求成功发送,信封大小大于8 KB。

根据官方的cxf apache文档,可以使用Spring配置文件更改cxf客户端行为:

无需更改java客户端的代码行。

- 1- cxf配置文件

创建 cxf.xml 弹簧配置文件:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="
http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <http-conf:conduit name="*.http-conduit">
        <http-conf:client AllowChunking="false"/>
    </http-conf:conduit>
</beans>

- 2- cxf.config.file.url java系统属性

编辑JBOSS批处理文件或脚本文件,以便将此系统属性添加到java命令。

值是指向cxf.xml文件的URL,windows示例如下所示:

-Dcxf.config.file.url=file:/C:/JBoss-7.1.1.Final/standalone/configuration/cxf.xml
  

以下是Linux / UNIX的示例:

-Dcxf.config.file.url=file:///home/jay/as/JBoss-7.1.1.Final/standalone/configuration/cxf.xml

- 3-重启JBOSS

- 4-测试

- 5-忽略发送请求时生成的WARNING消息

我认为应该找到http://cxf.apache.org/transports/http/configuration XML架构命名空间的 NamespaceHandler ,因为下面有这个jar:

C:/JBoss-7.1.1.Final/modules/org/apache/cxf/main/cxf-rt-transports-http-2.4.6.jar
  

无论如何,网络服务请求已成功发送!!
