我的程序用 spring + struts + mybatis 写成，在 tomcat 7.x 上可正常执行，因为开发完成，要部署到 JBoss AS 7.1，结果可以部署的上去，但是要 enable 时，会出现如下错误:

10:17:41,978 WARN [org.jboss.as.ee] (MSC service thread 1-7) JBAS011006: Not installing optional component org.springframework.http.server.ServletServerHttpAsyncRequestControl due to exception: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011054: Could not find default constructor for class org.springframework.http.server.ServletServerHttpAsyncRequestControl

请问这是什么原因呢？

基本上JBOSS上，要部属SPRING需要要设定档上做一些手脚

目前找到的解决办法，好像是要在 META-INF 下，增加一个名为 jboss-deployment-structure.xml 的档案，内容如下:

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
        <deployment>
            <dependencies>
                <module name="org.apache.commons.logging"/>
                <module name="org.springframework" >
                    <imports>
                        <include path="META-INF**"/>
                        <include path="org**"/>
                    </imports>
                </module>
            </dependencies>
        </deployment>
</jboss-deployment-structure>

结果还是会有错，如下: ╮（﹀＿﹀）╭

22:38:35,326 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC00001: Failed to start service jboss.module.service."deployment.xxx.war".main: org.jboss.msc.service.StartException in service jboss.module.service."deployment.xxx.war".main: Failed to load module: deployment.xxx.war:main

at org.jboss.as.server.moduleservice.ModuleLoadService.start(ModuleLoadService.java:91) [jboss-as-server-7.1.1.Final.jar:7.1.1.Final] 

你放错地方了，是放在WEB-INF里面

下面内容仅供参考，因为LOG机制改用slf4j，还有好像用JPA机制，细部请根据自己的项目调整

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
  <deployment>
    <exclude-subsystems>
      <subsystem name="jpa" />
    </exclude-subsystems>
    <exclusions>
      <module name="org.slf4j" />
        </exclusions>
  </deployment>
</jboss-deployment-structure>
