标签:style   http   io   ar   color   os   使用   sp   java   

三. 分模块配置方法

     <inclue file=""></include>


XML


cheliang.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>
    
  <package name="cheliang" namespace="/cheliang" extends="struts-default">
       <action name="cheliang" class="com.java1234.action.CheLiangAction">
            <result name="success">${pageContext.request.contextPath}/success.jsp</result>
       </action>
 
  </package>

</struts>

zichan.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>
    
  <package name="zichan" namespace="/zichan" extends="struts-default">
       <action name="zichan" class="com.java1234.action.ZiChanAction">
            <result name="success">${pageContext.request.contextPath}/success.jsp</result>
       </action>
 
  </package>

</struts>

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>
    
  <include file="cheliang.xml"></include>
  <include file="zichan.xml"></include>

</struts>

action


CheLiangAction.java

package com.java1234.action;

import com.opensymphony.xwork2.ActionSupport;

public class CheLiangAction extends ActionSupport{

     /**
     *
     */
     private static final long serialVersionUID = 1L;

     @Override
     public String execute() throws Exception {
          System.out.println("执行了CheLiangAction Action的默认方法");
          return SUCCESS;
     }
}

ZiChanAction.java

package com.java1234.action;

import com.opensymphony.xwork2.ActionSupport;

public class ZiChanAction extends ActionSupport{

     /**
     *
     */
     private static final long serialVersionUID = 1L;

     @Override
     public String execute() throws Exception {
          System.out.println("执行了ZiChanAction Action的默认方法");
          return SUCCESS;
     }

}

四.  使用通配符


action


GradeAction.java

package com.java1234.action;

import com.opensymphony.xwork2.ActionSupport;

public class GradeAction extends ActionSupport{

     private String name;
    
    
     public String getName() {
          return name;
     }

     public void setName(String name) {
          this.name = name;
     }


     public String list()throws Exception{
          System.out.println("班级查找");
          name="班级查找";
          return SUCCESS;
     }
    
     public String add()throws Exception{
          System.out.println("班级添加");
          name="班级添加";
          return SUCCESS;
     }
    
     public String update()throws Exception{
          System.out.println("班级修改");
          name="班级修改";
          return SUCCESS;
     }

     

     public String delete()throws Exception{
          System.out.println("班级删除");
          name="班级删除";
          return SUCCESS;
     }

}

StudentAction.java

package com.java1234.action;

import com.opensymphony.xwork2.ActionSupport;

public class StudentAction extends ActionSupport{

     private String name;
   
     public String getName() {
          return name;
     }

     public void setName(String name) {
          this.name = name;
     }

     public String list()throws Exception{
          System.out.println("学生查找");
          name="学生查找";
          return SUCCESS;
     }
    
     public String add()throws Exception{
          System.out.println("学生添加");
          name="学生添加";
          return SUCCESS;
     }
    
     public String update()throws Exception{
          System.out.println("学生修改");
          name="学生修改";
          return SUCCESS;
     }
    
     public String delete()throws Exception{
          System.out.println("学生删除");
          name="学生删除";
          return SUCCESS;
     }     
}

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.enable.DynamicMethodInvocation" value="true" />
 
  <package name="manage" namespace="/" extends="struts-default">
      
       <!-- <action name="student_*" class="com.java1234.action.StudentAction" method="{1}">
            <result name="success">success.jsp</result>
       </action>

      
       <action name="grade_*" class="com.java1234.action.GradeAction" method="{1}">
            <result name="success">success.jsp</result>
       </action> -->
      
       <!-- <action name="*_*" class="com.java1234.action.{1}Action" method="{2}">
            <result name="success">success.jsp</result>
       </action> -->

      
       <action name="student" class="com.java1234.action.StudentAction">
            <result name="success">success.jsp</result>
       </action>
      
       <action name="grade" class="com.java1234.action.GradeAction">
            <result name="success">success.jsp</result>

       </action>
 
  </package>

</struts>

第六节.动态方法调用 

            <constant name="struts.enable.DynamicMethodInvocation" value="true" />

<a href="grade!update" target="_blank">班级信息修改</a>&nbsp;
<a href="grade!delete" target="_blank">班级信息删除</a>&nbsp;<br/>

</body>
</html>



第七节:  Action生命周期


Action


HelloAction

public class HelloAction extends ActionSupport{

     /**
     *
     */
     private static final long serialVersionUID = 1L;

     public HelloAction() {
          System.out.println(this);
     }

     @Override
     public String execute() throws Exception {
          // TODO Auto-generated method stub
          return SUCCESS;
     }
    
}

struts.xml

<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    
 
  <package name="manage" namespace="/" extends="struts-default">
      
       <action name="hello" class="com.java1234.action.HelloAction">
            <result name="success">success.jsp</result>
       </action>
  </package>

</struts>

注意:每次请求都会创建action实例,Spring默认是单例
