Struts2未找到操作错误

我正在将我的应用程序服务器从Jboss 4.2迁移到7.1。我在Struts配置中遇到以下错误。在struts.xml中定义的操作正在调用，Action程序包中的操作未被调用。我也发布我的Action，struts.xml和堆栈跟踪。Struts2未找到操作错误

我Struts.xml：

<constant name="struts.convention.action.packages" value="com.infotech.project.web.action" /> 
<constant name="struts.convention.package.locators" value="actions,action" /> 


<constant name="struts.convention.result.path" value="/WEB-INF/jsp" /> 

<constant name="struts.convention.default.parent.package" value="project" /> 


<package name="default" namespace="/" extends="struts-default,json-default" /> 
<constant name="struts.devMode" value="true" /> 

<package name="project" 
    extends="struts-default,json-default,jfreechart-default, jasperreports-default" 
    namespace="/"> 
      <!-- more action names goes here --> 
    </package>

我LoginAction.java：

package com.infotech.project.web.action; 

import com.opensymphony.xwork2.ActionContext; 
import com.opensymphony.xwork2.ActionSupport; 

@SuppressWarnings("serial") 
@Result(type="json") 
public class LoginAction extends ActionSupport implements SessionAware { 


@SuppressWarnings("unchecked") 
@SkipValidation 
@Action(value = "/loginValidate", results = { @Result(name = "success", params = {"ignoreHierarchy","false"}) }) 
public String validateUserLogin() { 
    // validation code goes here 
} 
    }

更新到2.3.4的Struts后：

@SkipValidation批注可能非常有用，而不是定义允许从验证中排除某些方法的自定义拦截器堆栈。 –

BTW'com.lntinfotech.virtuoso.web.action.DttjoinAction'没有在配置中提及。而noclassdeffound exceprion意味着这个动作不存在，并且你的配置错误。 –

com.lntinfotech.virtuoso.web.action是包含我所有Action类的Action Package。 xwork-core 2.3.4无法识别导致Action未定义错误的Action类。任何方案？ –

我认为这个问题可能来自于你在同一个命名空间有两个包。尝试删除一个包，或更改其中之一的命名空间（也许是第一个，也就是空）

编辑：

这是Bug WW-3662: (Struts2) convention-plugin not work in jboss-7.0.0

正如你可以看到，它在最新版本中得到解决。

因此，如果您需要迁移到JBoss 7，您需要迁移到Struts 2.3.3或更高版本。

希望帮助

不，我试图通过删除默认包以及更改默认包的命名空间都dint工作:( –

是的，我将我的struts版本升级到2.3.4，之后，我得到的类未定义error.I更新问题与新的堆栈跟踪 –

现在可能是由于同一个库的多个版本在您的项目上...仔细检查它 –

使用@Namespace("/")为您的操作。并使用@Action(value = "loginValidate"，以便您可以从动作映射中找到您的操作。如果仍然没有帮助尝试删除

<constant name="struts.convention.action.packages" value="com.infotech.project.web.action" /> 
<constant name="struts.convention.package.locators" value="actions,action" /> 


<constant name="struts.convention.result.path" value="/WEB-INF/jsp" />

编辑：

如果使用Convention插件，为什么你有在struts.xml中包。从XML中删除所有重复的配置。使用@ParentPackage("default")或

<constant name="struts.convention.default.parent.package" value="default"/>

我试过所有的建议力量工作.. –

@Kabilan看到我的编辑，并尝试这种建议。 –

ur solutions dint工作。反正谢谢你提出一些答案.. –

关注罗马C'S指令和下面的行添加到您的struts.xml

<constant name="struts.convention.package.locators.basePackage" value="com.infotech.project.web.action"/>

我建议使用的配置，浏览器插件，以确保您调用之前注释的行动成功加载他们。
