刚学Struts2，访问index.jsp页面正常，访问login.jsp页面就报错

我用的是通配符的方式访问，输入
http://localhost:8088/TestStruts/TestStruts_index.action时可以跳转到index.jsp页面，
但输入http://localhost:8088/TestStruts/TestStruts_login.action时，
就报There is no Action mapped for namespace [/] and action name [TestStruts_login] associated with context path [/TestStruts].

struts.xml代码如下：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"

"http://struts.apache.org/dtds/struts-2.5.dtd">

<constant name="struts.action.extension" value="do,action"></constant>

<constant name="struts.serve.static.browserCache" value="false"></constant>

<constant name="struts.configuration.xml.reload" value="true"></constant>

<constant name="struts.devMode" value="true"></constant>

<constant name="struts.enable.DynamicMethodInvocation" value="false"></constant>


<package name="default" namespace="/" extends="struts-default">
    <action name="*_*" method="{2}" class="com.test.action.{1}" >
        <result name="login">/login.jsp</result>
        <result name="index">/{2}.jsp</result>
    </action>


</package>

麻烦大神解惑~

问题已解决，应该是Struts2版本问题，把原来的

加上一句strict-method-invocation="false"，就可以了

谢谢楼上的解答，虽然还没看^_^

struts2好像由于安全问题用的不多了，不过学习框架入门还是很有必要的

struts2异常java.lang.NoSuchMethodException: com.struts.action.UserAction.create(): 原来用的struts2.0版本，运行项目没有问题。后来换了struts2.2.1版本后，只要访问Action，都会出现 java.lang.NoSuchMethodException: com.struts.action.UserAction.create()类似的错误，就是说Action中找不到create这个方法。 struts.xml [code="xml"] <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <include file="defaults.xml"></include> <package name="struts.action.user" namespace="/user" extends="struts-default"> <interceptors> <interceptor name="loginInterceptor" class="com.innoact.struts.interceptor.LoginInterceptor"> </interceptor> </interceptors> <action name="user_*" class="com.innoact.struts.action.UserAction" method="{1}"> <interceptor-ref name="loginInterceptor"> <param name="excludeMethods">login,register</param> <param name="includeMethods">update</param> </interceptor-ref> <interceptor-ref name="defaultStack"></interceptor-ref> <result name="success">/main.jsp</result> <result name="login">/index.jsp</result> </action> </package> </struts> [/code] 我设定的是方法拦截，所以当进入user_update.action的时候，没有问题，因为它可以进入拦截器。但是我没有拦截login和register方法，进入这两个方法时就会出错。说找不到create方法。我Action里面没有这个方法，肯定找不到。而且继承的ActionSupport的里面也没有这个方法，只有excute方法。不知道为什么struts会非要找这个create方法！后来上网查了半天，人家说去掉<include file="defaults.xml"></include>这部分就可以。 defaults.xml [code="xml"] <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="defaults" extends="struts-default"> <global-results> <result name="error">/error.jsp</result> </global-results> <global-exception-mappings> <exception-mapping exception="java.lang.NullPointerException" result="error" /> <exception-mapping exception="java.lang.Exception" result="error" /> </global-exception-mappings> </package> </struts> [/code] 试了下，果然奏效。但是用原来struts2.0的版本没有这样的问题啊！不知道为什么，哪位高人来解释下，感激不尽！最好能带 struts的源代码分析下！还有struts2.0和2.1之后的地方，有哪些区别？ Oh My God!现在又不行了。不知道是不是我刚才手动加的create方法没去掉，现在又报这个错误，蛋疼啊！高手速来解答！感激不尽啊！

struts2.5.8动态方法调用使用通配符无效: 我在使用struts2.5.8时，在jsp页面中： ```jsp <s:form namespace="/zzw" action="login"> <s:textfield name="username" key="username"/> <s:textfield name="password" key="password"/> <s:submit key="login" action="login_login"/> <s:submit key="register" action="login_register"/> </s:form> ``` 在struts.xml中： ```xml <constant name="struts.enable.DynamicMethodInvocation" value="false"/> <package name="zzw" extends="struts-default" namespace="/zzw" strict-method-invocation="false"> <global-allowed-methods>regex:.*</global-allowed-methods> <action name="login_*" class="com.zzw.action.LoginAction"> <result name="success">/result.jsp</result> </action> </package> ``` 结果是点击jsp页面的登录/注册页面，跳转到了LoginAction，但没有调用相应的方法（login或register），求大神帮下忙，谢谢！

使用Struts2配置国际化的问题,请大家帮忙.谢谢.: 我在使用Struts2配置国际化的问题时, 在jsp页面使用 <h2><s:text name="wmbmm.login.username"/></h2> 引用国际化文件的key. 然后再src的目录下,配置了struts.properties属性文件中配置了. struts.custom.i18n.resources=globalMessages 在项目的src目录下, 配置了 globalMessages_en_US.properties wmbmm.login.username=UserName wmbmm.login.password=PassWord globalMessages_zh_CN.properties wmbmm.login.username=\u7528\u6237\u540D wmbmm.login.password=\u5BC6\u7801 重启服务器,打开浏览器访问的时候,就报下面这个错误!请问还需要配置什么吗? 严重: Servlet.service() for servlet jsp threw exception The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter.

struts2 result的jsp页面如何规定width和height？: struts2 result的jsp页面如何规定width和height？比如我的struts.xml中定义了下面这段 [code="java"] action name="xxx" class="xxxAction"> <result name="input">/index.jsp</result> <result name="error">/error.jsp</result> <result name="success">/message.jsp</result> </action> [/code] 当xxxAction return success后，IE浏览器弹出了message.jsp页面我如何设定弹出的IE页面的属性，像toolbar=no这样的设置? 我知道js中的window.open()第三个参数就能实现弹出窗口的属性设置，比如toolbar=no。但是在struts2架构下该在哪里写下toolbar=no这行代码? 我们再来看一下struts2的"运行轨迹" index.html中定义 <s:form action="login" target="_blank"> <s:submit value="登录" /> </s:form> 当我点击登录后执行loginAction.java中的excute() 然后excute()返回了"success" 考虑到我在struts.xml中配置了 <action name="login" class="loginAction"> <result name="success">/message.jsp</result> </action> 所以浏览器弹出了一个新的窗口我想解决的就是如何让这个新弹出的窗口上没有菜单栏和地址栏

struts2表单验证 jsp页面显示不了错误信息: 目前正在用struts2创建项目为了减小代码的耦合度使bean类更纯粹点在表单验证这一块我另外写了一个类然后用模型驱动（ModelDriven）再重写validate方法 [code="java"] package com.pp.action.login; import com.opensymphony.xwork2.ActionSupport; import com.opensymphony.xwork2.ModelDriven; import com.pp.bean.Login; public class myvalidation extends ActionSupport implements ModelDriven<Login> { private Login login = new Login(); private String mailname; private String username; private String password; public Login getModel() { return login; } @Override public void validate() { // System.out.println("validate"); // mailname = login.getMailname().trim(); // username = login.getUsername().trim(); // password = login.getPassword().trim(); // System.out.println("mail"+mailname); // System.out.println("username---"+username); // System.out.println("password---"+password); if(login.getMailname().equals("")) { this.addFieldError("mailname","mail name should not be blank!"); System.out.println("mail validate"); //this.addActionError("mailname should not be blank!"); } if(login.getMailname().length()<1) { this.addFieldError("mailname","length error"); System.out.println("mail length validate"); //this.addActionError("length error"); } if(login.getUsername().equals("") || login.getUsername().length()<6 || login.getUsername().length()>12) { this.addFieldError("username","username should not be blank!"); System.out.println("username validate"); //this.addActionError("username should bot be blank"); } if(login.getPassword().equals("")) { this.addFieldError("password","fill your password"); System.out.println("password validate"); //this.addActionError("fill your password"); } } @Override public String execute() throws Exception { return SUCCESS; } } [/code] 后台都有显示mail validate username validate等输出信息说明有进入判断条件但是在JSP页面就是显示不出来错误信息 reg.jsp页面在form表单之前也有加FieldError的标签： [code="java"] <body> <s:fielderror></s:fielderror> <s:form action="login2">  <s:textfield name="mailname" label="邮箱"></s:textfield> <s:textfield name="username" label="用户名"></s:textfield> <s:textfield name="password" label="密码"/> <s:submit name="submit" ></s:submit> </s:form> <br> </body> [/code] acton如下，用的是login2来处理表单： [code="java"] <include file="struts-default.xml" /> <package name="tutorial" extends="struts-default"> <action name="login" class="com.pp.action.login.checklogin"> <result name="success">success.jsp</result> <result name="error">error.jsp</result> <result name="login">login.jsp</result> </action> <action name="login2" class="com.pp.action.login.myvalidation"> <result>success.jsp</result> <result name="input">reg.jsp</result> </action> </package>  </struts> [/code] 到底是什么问题希望各位帮忙看下非常感谢。。。 [b]问题补充：[/b] Login类是另外写的然后为用模型驱动ModelDriven<Login> 其中有个getModel()方法重载Login的javaBean类首先我想说 struts2的表单验证是不是有两种：一是直接override validate方法；二是直接对Action处理类配置xml文件不是吗 [b]问题补充：[/b] wocsok (中级程序员)说得不对既然是使用ModelDriven，它的作用就像是在Myvalidation里面写了Login类的getXX和setXX方法作用是一样的。我的问题是在原先的Login里面的validate()方法没注释掉，然后两个validate()方法冲突了，只要把Login里面的validate注释掉就OK了

struts2.1整合spring2.5后使用fileUpload的文件上传: struts2.1单独使用fileUpload没有问题，可以正常使用。但是整合了spring2.5.6之后，就出现了一个让我匪夷所思的问题。问题是这样：整合后，再上传文件，如果符合fileUpload的要求，那么上传没问题。但是，如果文件上传的类型或者文件的大小不符合要求，那么本次上传失败。这也没问题。问题是，在失败之后，我刷新页面，上传一个符合要求的文件，还是显示上传失败的信息。而且文件的确上传失败了，后台也不走action了，感觉被fileUpload直接拦截了，并且拦截器，获得的还是以前那个失败的信息。这个我就晕了。有谁知道这个问题产生的原因是什么吗？请告知！谢谢！以下是我使用的代码: web.xml <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app> applicationContext.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <bean id="upload" class="cn.sure.action.UploadAction"> </bean> </beans> struts.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="struts2" extends="struts-default"> <action name="upload" class="upload"> <result name="input">/upload.jsp</result> <result name="success">/index.jsp</result> <param name="savePath">/upload</param> <interceptor-ref name="fileUpload"> <param name="maximumSize">204800</param> </interceptor-ref> <interceptor-ref name="defaultStack"></interceptor-ref> </action> </package> </struts> UploadAction.java package cn.sure.action;
