我正在使用Glassfish 4.0和Eclipse Luna 4.4.0并下载了最新的struts2库。我已经将所有struts2 jar添加到项目中,只是为了确定。我创建了一个动态Web项目。这是我的 web.xml 文件:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
<display-name>Struts2Starter</display-name>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

<param-value>org.demian.javabrains.action</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
这是我的 struts.xml 文件:
<?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.devMode" value="true" />
<package name="basicstruts2" extends="struts-default">
<action name="getTutorial" class="org.demian.javabrains.action.TutorialAction" method="execute">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>
这是我的 TutorialAction.java :
package org.demian.javabrains.action;
import java.util.Date;
import com.opensymphony.xwork2.ActionSupport;
public class TutorialAction extends ActionSupport {
private static final long serialVersionUID = 1L;
public String execute() throws Exception {
System.out.println("Hello from execute!");
Date d = new Date();
long milliseconds = d.getTime();
if (milliseconds % 2 == 0)
return SUCCESS;
else
return ERROR;
}
}
我创建的其他2个页面是简单的.jsp
页面:success.jsp
和error.jsp
,两者都在主目录中。如果我输入此网址:http://localhost:8080/Struts2Starter/success.jsp
,我会获得成功页面,这意味着Glassfish正在运行,但如果我输入此网址:http://localhost:8080/Struts2Starter/getTutorial.action
我总是收到http错误404.我按照此页面上的说明操作:struts2 documentation。谁能告诉我我做错了什么?
我尝试通过插入此链接
来使用struts2-config-browser-plugin
调试应用程序
<a href="<s:url action="index" namespace="config-browser" />">Launch the configuration browser</a>
进入我的success.jsp
页面,如下所示:http://struts.apache.org/release/2.2.x/docs/debugging-struts.html。当我点击链接时,它会给出另一个404错误。我不明白。这就像Struts2根本不起作用。这是启动服务器时的日志:https://dl.dropboxusercontent.com/u/27349592/glassfish_server_startup.txt
我安装了Tomcat 8.0.11,这是我启动服务器时收到的错误消息:https://dl.dropboxusercontent.com/u/27349592/tomcat8_server_startup.txt
答案 0 :(得分:1)
我终于成功了!我做的第一件事就是删除我所包含的所有罐子,只添加我需要的罐子。以下是我加入的罐子:https://dl.dropboxusercontent.com/u/27349592/2014-09-05%2022_36_58-Preferences%20%28Filtered%29.png
在此之后,我在属性中配置了库 - &gt;部署项目组装:https://dl.dropboxusercontent.com/u/27349592/2014-09-05%2022_37_29-Properties%20for%20Struts2Tutorial.png

</struts>
我仍然不知道究竟是什么问题,但我想这可能是因为struts2库中存在依赖关系。
