大家好，我在使用 Struts 2 Annotated Actions 时遇到问题

在我的pom.xml我有：

<!-- STRUTS2 annotation -->
<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-convention-plugin</artifactId>
    <version>2.3.16.3</version>
</dependency>

<!-- STRUTS2 SPRING integration -->
<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-spring-plugin</artifactId>
    <version>2.3.15.1</version>
</dependency>

在我的web.xml：

<filter>
  <filter-name>struts2</filter-name>
    <filter-class>com.agiletec.apsadmin.system.dispatcher.StrutsPrepareAndExecuteFilter</filter-class>
      <init-param>
      <param-name>struts.devMode</param-name>
      <param-value>true</param-value>        
      </init-param>
      <init-param>
      <param-name>struts.objectFactory</param-name>
      <param-value>spring</param-value>        
      </init-param>        
<init-param>
    <param-name>actionPackages</param-name>
    <param-value>it.aicof.projects.openMED.aps.internalservlet.actions</param-value>
</init-param>          
</filter>  
  
<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/do/*</url-pattern>
</filter-mapping>
<filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/struts/*</url-pattern>
</filter-mapping>

我有两个动作类：

@Namespace("/budget")
@SuppressWarnings("serial")
public class BudgetAction extends BaseAction {
    
    @Action(value = "/start", results = { @Result(name = "success", location = "/WEB-INF/openmed/aps/jsp/internalservlet/budget/budget.jsp") })
    public String start(){
.......


@Namespace("/upload")
@SuppressWarnings("serial")
public class UploadAction extends BaseAction {

    @Action(value = "/init", results = {
        @Result(name = "success", location = "/WEB-INF/openmed/aps/jsp/internalservlet/upload/upload.jsp")})
    public String init() {
        .....

如果我调用第一个http://localhost:8080/openMED/do/budget/start.action一切正常，但是当我调用第二个时，http://localhost:8080/openMED/do/upload/init.action我会收到此错误

 There is no Action mapped for namespace [/do] and action name [init] associated with context path [/openMED]. - [unknown location]

怎么了？两个类的配置方式相同。

根据错误信息

2014-07-18 15:49:15,454 - 错误 - 调度程序 - 处理请求期间发生异常：没有为命名空间 [/do] 映射的操作和与上下文路径 [/openMED] 关联的操作名称 [init]。- [未知位置]。

您已使用 url/openMED/do/upload/init.action但您的操作已映射到命名空间/upload。命名空间是从上下文路径到操作名称的路径。您可以找到有关命名空间配置的更多信息。您还可以查看此示例以更好地理解命名空间的概念。

您应该更改操作映射

@Namespace("/do/upload")
@SuppressWarnings("serial")
public class UploadAction extends BaseAction {

@Action(value = "init", results = {@Result(name = "success", location = "/WEB-INF/openmed/aps/jsp/internalservlet/upload/upload.jsp")})
public String init() {
