java - JBOSS 上的 apache cxf 客户端的 Web 服务请求 (>8KB) 失败 - HTTP 响应 '411: Length Required'

Question

Web 应用程序正在使用 apache cxf 客户端向远程 Web 服务发送请求。

当此 Web 应用程序部署在 Tomcat 上时，一切正常。

当此Web应用程序部署在JBOSS上并且主体(信封)大小大于8 KB时，请求发送失败；生成以下错误:

HTTP 流模式似乎已切换为分块。

What do you think of this first assumption?

在apache cxf官方文档中可以发现，可以提供一个spring配置文件来改变cxf客户端的行为。

What is the configuration file content?

Answer 1

I answer to my own question, because after additional tests, the configuration described below worked for me.

首先，该错误可能是由于cxf客户端自动切换到分块传输模式而产生的；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，然后成功发送信封大小大于 8 KB 的请求。

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

• https://cxf.apache.org/docs/client-http-transport-including-ssl-support.html
• https://cxf.apache.org/docs/configuration.html

无需更改java客户端的代码行。

- 1- cxf配置文件

创建cxf.xml spring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 批处理或脚本文件，以便将此系统属性添加到 java 命令中。

该值是指向cxf.xml文件的URL，Windows示例如下:

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

There is below an example for Linux/UNIX:

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

- 3-重新启动JBOSS

- 4- 测试

- 5- 忽略发送请求时生成的 WARNING 消息

我认为http://cxf.apache.org/transports/http/configuration的NamespaceHandler应该找到 XML 模式命名空间，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

Anyway, the webservice request is successfuly sent !!
