Question

您好我是Struts 2和所有Java Web开发的新手，我使用maven创建了一个基本的struts2应用程序，然后添加了struts2-rest-plugin来构建我的项目;这是pom.xml：

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

      <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>

       </configuration>
      </plugin>
     </plugins>
    </build>
</project>

web.xml和struts.xml如下：

的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="starter" version="2.4" 
         xmlns="http://java.sun.com/xml/ns/j2ee" 
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

 </context-param>

 <!-- Filters -->

    <!-- Welcome file lists -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.jsp</welcome-file>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

</web-app>

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>

 <constant name="struts.convention.action.suffix" value="Controller"/>
 <constant name="struts.convention.action.mapAllMatches" value="true"/>
 <constant name="struts.convention.default.parent.package" value="rest-default"/>
 <constant name="struts.convention.package.locators" value="example"/>

</struts>

现在我有一个包org.apache.struts2.rest.example的包OrdersController.java（取自struts2-rest-showcase示例）; 正在运行mvn jetty：运行并点击网址： http://localhost:8080/tutorial/orders/ 会导致错误404;

我在做什么？

好的家伙我发现了问题; maven默认生成一个struts.properties文件，这两行很麻烦：

struts.mapper.class = org.apache.struts2.dispatcher.mapper.DefaultActionMapper struts.action.extension =动作

评论它们并且XML将是有效的（你调查故事的其余部分）
