问题描述

我在NetBeans 7.2.1中在struts 2.3.16上尝试我的第一个应用程序。它在输入URL时显示以下错误 - http：// localhost：8080 / TestStruts / Test.action （有一个 Test.jsp page）。

 警告：找不到操作或结果：/TestStruts/Test.action 
没有与上下文路径[/ TestStruts]相关联的名称空间[/]和操作名称[Test]映射的操作。 -  [未知位置]

当URL从 .action 更改为 .jsp c $ c>像 http：// localhost：8080 / TestStruts / Test.jsp ，它会显示以下警告。

  Dec 22，2013 9:00:44 PM org.apache.struts2.components.ServletUrlRenderer warn 
警告：找不到指定操作的配置：'test'in namespace：'/ TestStruts'。表单操作默认为'action'属性的文字值。 
 org.apache.struts2.components.ServletUrlRenderer warn 
警告：没有为指定的操作找到配置：'test'in namespace：'/ TestStruts'。表单操作默认为'action'属性的文字值。

我缺少什么？

解决方案

因为 / TestStruts 是部署您的应用程序的上下文路径。它与包中的命名空间具有相同的路径。尝试

  http：// localhost：8080 / TestStruts / TestStruts / test.action

当URLS从struts标签呈现时，它试图找到一个相应的动作配置。如果没有找到配置，则发出警告。


I'm trying my first application on struts 2.3.16 in NetBeans 7.2.1. It shows the following error on entering a URL - http://localhost:8080/TestStruts/Test.action (There is a Test.jsp page).

The Test.jsp page:

<s:form namespace="/TestStruts" action="test">
    <table border="0" class="">
            <tr>

                <td>
                    <s:textfield id="name" name="name" label="Enter your name"/>
                </td>
            </tr>
            <tr>
                <td>
                    <s:textfield id="email" name="email" label="Enter your email"/>
                </td>
            </tr>
            <tr>
                <td></td>
                <td><s:submit value="Submit"/></td>
            </tr>
    </table>            

</s:form>

The action class:

package actions;
import com.opensymphony.xwork2.ActionSupport;

public final class TestAction extends ActionSupport
{
    private static final String SUCCESS = "success";
    private String name;
    private String email;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String execute() throws Exception
    {
        System.out.println("name = "+name);
        System.out.println("email = "+email);
        return SUCCESS;
    }
}

The strtus.xml file:

In addition to jar files of Spring, I have added the following jar files to the classpath.

  • commons-beanutils-1.8.0.jar
  • commons-chain-1.2.jar
  • commons-collections-3.1.jar
  • commons-digester-2.0.jar
  • commons-fileupload-1.3.jar
  • commons-io-2.2.jar
  • commons-lang3-3.1.jar

  • commons-validator-1.3.1.jar
  • freemarker-2.3.19.jar
  • javassist-3.11.0.GA.jar
  • ognl-3.0.6.jar
  • struts2-core-2.3.16.jar
  • struts2-spring-plugin-2.3.16.jar
  • xwork-core-2.3.16.jar

When the URL is changed to .jsp from .action like http://localhost:8080/TestStruts/Test.jsp, it shows the following warnings.

Dec 22, 2013 9:00:44 PM org.apache.struts2.components.ServletUrlRenderer warn
WARNING: No configuration found for the specified action: 'test' in namespace: '/TestStruts'. Form action defaulting to 'action' attribute's literal value.
Dec 22, 2013 9:00:45 PM org.apache.struts2.components.ServletUrlRenderer warn
WARNING: No configuration found for the specified action: 'test' in namespace: '/TestStruts'. Form action defaulting to 'action' attribute's literal value.

What am I missing?

解决方案

Because /TestStruts is a context path at which deployed your application. It has the same path as namespace in your package. Try

http://localhost:8080/TestStruts/TestStruts/test.action

When URls is rendering from the struts tags it's trying to find a corresponding action configuration. If there's no config found the warning is issued.
