Jboss eap升级到7.2使用Jersey的问题

最近升级Jboss的时候遇到了一个问题，我们使用jersey提供web服务的，然后客户端也是使用Jersey-Client调用后台服务的，但是在jboss从6.4 升级到7.2 之后遇到了一个错误：

Caused by: com.oocl.csc.frm.soa.proxy.exception.FWProxyException: javax.ws.rs.ProcessingException: RESTEASY003145: Unable to find a MessageBodyReader of content-type text/html;charset=UTF-8 and type class java.lang.String

从错误信息中可以看到这是从resteasy报出的问题，而不是我们预想的使用jersey-client来读取response。之前在jboss-eap-6.4中我们为了禁用resteasy，在web.xml添加了这些config：

    <context-param>
        <param-name>resteasy.scan</param-name>
        <param-value>false</param-value>
    </context-param>
    <context-param>
        <param-name>resteasy.scan.providers</param-name>
        <param-value>false</param-value>
    </context-param>
    <context-param>
        <param-name>resteasy.scan.resources</param-name>
        <param-value>false</param-value>
    </context-param>

看起来这些配置没有将所有的resteasy模块都禁用掉，客户端还是使用了Resteasy，后来查了一下文档，如果想在jboss-eap-7中完全禁用resteasy需要在jboss-deployment-structure.xml中添加一下配置：

 <exclusions>
          <module name="javaee.api" />
          <module name="javax.ws.rs.api"/>
          <module name="org.jboss.resteasy.resteasy-jaxrs" />
</exclusions>

其中前面两个modulejavaee.api和javax.ws.rs.api是必须要加的，需要将jboss中的javaeemodule都禁用到，如果只是排除org.jboss.resteasy.resteasy-jaxrs好像并不会完全禁用掉resteasy.
