Struts 2 +梅文 + Struts 2 Rest 插件帮助

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"?>

</project>

web.xml和struts.xml如下：

web.xml:

<web-app id="starter" version="2.4" 
         xmlns="http://java.sun.com/xml/ns/j2ee"

         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

        <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>

现在我有包org.apache。 struts2.rest.example 和类 OrdersController.java （取自 struts2-rest-showcase 示例）； 运行 mvn jetty:run 并点击 url: http://localhost: 8080/tutorial/orders/ 导致错误 404；

我做错了什么？

Answer 1

好吧，伙计们，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=action

将它们注释掉，XML 就会有效（您调查故事的其余部分）
