构建后目录结果如下：

struts2 和struts1有很大的不同，它的核心特征是所有的实现都是通过interceptors(拦截器)，“value stack” (值栈)，OGNL(表达式语言)，以及包含了很多的注解使框架使用起来更简单。

下面一步一步构建学习Struts2。

工具：

1： Maven  Apache Maven 3.0.4

2:    JDK 1.7.0_10

3:     Eclipse4.2

4:     apache-tomcat-6.0.35

首先通过Maven构建一个Web项目。

Maven构建web项目的命令如下：

 

[plain] view plaincopyprint?
  1. mvn archetype:generate -DgroupId={project-packaging} -DartifactId={project-name} -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false  
mvn archetype:generate -DgroupId={project-packaging} -DartifactId={project-name} -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

然后构建我们的项目，首先进入到项目放置的位置：

 

然后执行构建命令：如下：

 

[plain] view plaincopyprint?

  2. le -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

构建成功后，生成的web项目的目录结构为：

 

|-src
   |---main
   |-----resources
   |-----webapp
   |-------index.jsp
   |-------WEB-INF
   |---------web.xml
   |-pom.xml

然后把需要引入的jar包在pom.xml中进行配置。

配置后的pom.xml文件如下：

配置pom.xml后，下一步需要导入到eclipse中，如果导入到eclispe中需要对项目进行转换，

 

转换为eclipse项目的命令  mvn  eclipse:eclipse -Dwtpversion=2.0  

如果运行以上命令首先需要进入到pom.xml的文件目录下：

运行结果如下：

执行以上命令就是通过maven下载相应的依赖jar包，然后生成了一下文件：

.classpath

.project

.setting

以上三个文件夹是执行mvn eclipse:eclipse -Dwtpversion=2.0命令得到的。

这里有一个问题，现在没有弄明白，导入到eclipse中后发现没有src/main/java目录，打开生成的.classpath文件在第一行加上

 

[plain] view plaincopyprint?
  1. <classpathentry kind="src" path="src/main/java" including="**/*.java"/>  
<classpathentry kind="src" path="src/main/java" including="**/*.java"/>

然后在相应的目录下创建java的文件夹即可；

 

加上这句话后.classpath文件的内容如下：

 

[plain] view plaincopyprint?
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <classpath>  
  3.   <classpathentry kind="src" path="src/main/java" including="**/*.java"/>

</classpath>

然后导入到eclipse中即可，导入后 的目录结构为：

如果把项目部署到tomcat上的时候，会出现 Tomcat version 6.0 only supports J2EE 1.2, 1.3, 1.4, and Java EE 5 Web modules

这个问题，解决方法；

找到路径E:\workspace\Struts2Example\.settings下面的org.eclipse.wst.common.project.facet.core文件

修改 <installed facet="jst.web" version="3.0"/> 为  <installed facet="jst.web" version="2.4"/> 即可；

修改后的文件为：

 

[plain] view plaincopyprint?
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <faceted-project>  
  3.   <fixed facet="jst.java"/>  
  4.   <fixed facet="jst.web"/>  
  5.   <installed facet="jst.web" version="2.4"/>  
  6.   <installed facet="jst.java" version="1.7"/>  
  7. </faceted-project>  
<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="jst.java"/>
  <fixed facet="jst.web"/>
  <installed facet="jst.web" version="2.4"/>
  <installed facet="jst.java" version="1.7"/>
</faceted-project>

然后再次进行部署就没有问题了。

 

首先创建：UserAction类：

 

[java] view plaincopyprint?
  1. package com.topwqp.action;  
  2.   
  3. public class UserAction {  
  4.     private String username;  
  5.   
  6.     public String getUsername() {  
  7.         return username;  
  8.     }  
  9.   
  10.     public void setUsername(String username) {  
  11.         this.username = username;  
  12.     }  
  13.       
  14.     public  String execute(){  
  15.         return "SUCCESS";  
  16.     }  
  17.   
  18. }  
package com.topwqp.action;

public class UserAction {
	private String username;

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}
	
	public  String execute(){
		return "SUCCESS";
	}

}

UserAction类很简单，不需要实现什么借口，或者继承什么类的， execute()方法是默认执行的方法，返回 SUCCESS是为了进行跳转转向。

 

login.jsp如下： 用到了struts2的标签库

 

[java] view plaincopyprint?
  1. <%@ page contentType="text/html; charset=UTF-8"%>  
  2. <%@ taglib prefix="s" uri="/struts-tags"%>  
  3. <html>  
  4. <head></head>  
  5. <body>  
  6.     <h1>Struts 2 Hello World Example</h1>  
  7.    
  8.     <s:form action="Welcome">  
  9.         <s:textfield name="username" label="Username" />  
  10.         <s:password name="password" label="Password" />  
  11.         <s:submit />  
  12.     </s:form>  
  13.    
  14. </body>  
  15. </html>  
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head></head>
<body>
    <h1>Struts 2 Hello World Example</h1>
 
    <s:form action="Welcome">
        <s:textfield name="username" label="Username" />
        <s:password name="password" label="Password" />
        <s:submit />
    </s:form>
 
</body>
</html>

 

 

welcome.jsp内容如下： 

 

[java] view plaincopyprint?
  1. <%@ page contentType="text/html; charset=UTF-8"%>  
  2. <%@ taglib prefix="s" uri="/struts-tags"%>  
  3. <html>  
  4. <head></head>  
  5. <body>  
  6.     <h1>Struts 2 Hello World Example</h1>  
  7.    
  8.     <h4>  
  9.         Hello  
  10.         <s:property value="username" />  
  11.     </h4>  
  12.    
  13. </body>  
  14. </html>  
<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head></head>
<body>
    <h1>Struts 2 Hello World Example</h1>
 
    <h4>
        Hello
        <s:property value="username" />
    </h4>
 
</body>
</html>

tomcat容器去加载web.xml文件，web.xml文件内容如下：

 

 

[html] view plaincopyprint?
  1. <!DOCTYPE web-app PUBLIC  
  2.  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"  
  3.  "http://java.sun.com/dtd/web-app_2_3.dtd" >  
  4.    
  5. <web-app>  
  6.     <display-name>Struts 2 Web Application</display-name>  
  7.    
  8.     <filter>  
  9.         <filter-name>struts2</filter-name>  
  10.         <filter-class>  
  11.                 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter  
  12.                 </filter-class>  
  13.     </filter>  
  14.    
  15.     <filter-mapping>  
  16.         <filter-name>struts2</filter-name>  
  17.         <url-pattern>/*</url-pattern>  
  18.     </filter-mapping>  
  19. </web-app>  
<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
 
<web-app>
    <display-name>Struts 2 Web Application</display-name>
 
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>
                org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
                </filter-class>
    </filter>
 
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

web.xml回去加载struts.xml文件，其中配置了拦截的通配符路径。

 

struts.xml文件的内容如下：

其中package的name属性不起其他作用，仅仅是一个标记，namespace属性有重要作用，对应于webapp/user 这个目录的命名空间，所以当访问

http://localhost:8080/Struts2Example/user/Login.action时  就是访问对应的http://localhost:8080/Struts2Example/user/pages/login.jsp

两个访问效果是一样的。

 

 

[html] view plaincopyprint?
  1. <?xml version="1.0" encoding="UTF-8" ?>  
  2. <!DOCTYPE struts PUBLIC  
  3. "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  
  4. "http://struts.apache.org/dtds/struts-2.0.dtd">  
  5.    
  6. <struts>  
  7.    
  8.     <package name="user" namespace="/user" extends="struts-default">  
  9.         <action name="Login">  
  10.             <result>pages/login.jsp</result>  
  11.         </action>  
  12.         <action name="Welcome" class="com.topwqp.action.UserAction">  
  13.             <result name="SUCCESS">pages/welcome.jsp</result>  
  14.         </action>  
  15.     </package>  
  16.    
  17. </struts>  
<?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>
 
    <package name="user" namespace="/user" extends="struts-default">
        <action name="Login">
            <result>pages/login.jsp</result>
        </action>
        <action name="Welcome" class="com.topwqp.action.UserAction">
            <result name="SUCCESS">pages/welcome.jsp</result>
        </action>
    </package>
 
</struts>

 

 

PS 如果是struts1 实现这个直接跳转的功能 代码如下：

 

[html] view plaincopyprint?
  1. <action  
  2.         path="/Login"  
  3.         type="org.apache.struts.actions.ForwardAction"  
  4.         parameter="/pages/login.jsp"/>  
	<action
			path="/Login"
			type="org.apache.struts.actions.ForwardAction"
			parameter="/pages/login.jsp"/>

跳转后如果提交就会提交到Welcome对应的action

 

路径为：http://localhost:8080/Struts2Example/user/Welcome.action

 

struts2的命名空间(namespace)对于模块化开发有很好的作用。

访问如下：

点击提交后页面挑战如下：
