Question

我是struts 2的新手，当你运行hello word例子时我得到了这个错误 HTTP状态404 - 没有映射名称空间/操作名称登录的操作。我把jsp页面放在wepapp / pages文件夹中，我该如何解决呢？

   @ResultPath(value="/")
   public class HelloController extends ActionSupport{

/**
 * 
 */
private static final long serialVersionUID = 1L;
private String name;

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
    @Action(value="/Login",results={@Result(name="success",location="pages/login.jsp")})
public String execute()throws Exception
{
    return "success";
}
   }

的web.xml

 <filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
 </filter>

 <filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
  </filter-mapping>

和这个pom文件

Answer 1

您必须在网址中调用操作名称：

http://localhost:<your-port>/Login.action

同时将操作名称更改为：

@Action(value="Login" ....

Answer 2

您的过滤器已弃用。从Struts 2.1.3开始，you need to change从FilterDispatcher到StrutsPrepareAndExecuteFilter。

迁移到至少2.3.16也是很好的，以避免多年来发现和修补的安全问题。

2.1很老了......

Answer 3

我解决了它，我必须在打包的命名操作中添加HelloController类，因为struts 2扫描位于打包名为“struts，struts2，action或actions”的带注释的类

Struts 2你好的话
