maven项目的结构

一、配置struts

1.相关jar依赖

2、web.xml配置

3、框架配置文件配置（三个）

二、动态方法调用

 第二种方法

三、传参

1、Modeldrier接口传参

2、set方法传参

3、通过对象属性传参

运行结果

 四、Struts与Tomcat的集成

方法：实现接口

运行结果

maven项目的结构

 src 

   main

       java 写代码的地方

       resources 放配置的地方

       wabapp  放页面的地方

   test

        java 写测试代码的地方

        resources 放测试代码对应配置的地方

一、配置struts

1.相关jar依赖

            org.apache.struts
            struts2-core
            2.5.13
        
 
 
        
            javax.servlet
            javax.servlet-api
            4.0.1
            provided
        

2、web.xml配置

  Archetype Created Web Application
  
    struts
    org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
  

   struts
   *.action

3、框架配置文件配置（三个）

struts-base.xml   

	
	
	
	
	

	
		regex:.*
	

struts.xml 

struts-sy.xml 里面做配置

	
	
	
	 
	  /bookEdit.jsp
	 
	 
	

二、动态方法调用

在struts-sy.xml 里面做配置

 

	  /bookEdit.jsp
	 

Demo1Action

package com.hpw.one.web;

import javax.servlet.ServletRequest;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

import com.hpw.one.entity.User;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class Demo1Action extends ActionSupport implements ModelDriven{
	

public String add() throws Exception {
	System.out.println("add方法...");
	return "bookEdit";
}

public String del() throws Exception {
	System.out.println("del方法...");
	return "bookEdit";
}

public String edit() throws Exception {
	System.out.println("edit方法...");
	return "bookEdit";
}

public User getModel() {
	return user1;
}


}

demo1.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>







struts的动态方法调用
新增

修改

删除

 第二种方法

在struts-sy.xml 里面做配置

    
	
 
	  /{2}.jsp

demo1.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>







struts的动态方法调用
删除

三、传参

1、Modeldrier接口传参

2、set方法传参

3、通过对象属性传参

package com.hpw.one.web;

import javax.servlet.ServletRequest;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

import com.hpw.one.entity.User;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class Demo1Action extends ActionSupport implements ModelDriven,ServletRequestAware,ServletResponseAware{
	
	private HttpServletRequest req;
	private HttpServletResponse resp;
	private User user1 = new User();
	private String sex;
	private User user2;
	
public User getUser1() {
		return user1;
	}

	public void setUser1(User user1) {
		this.user1 = user1;
	}

	public User getUser2() {
		return user2;
	}

	public void setUser2(User user2) {
		this.user2 = user2;
	}

public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

public String add() throws Exception {
	System.out.println("add方法...");
	return "bookEdit";
}

public String del() throws Exception {
	System.out.println("del方法...");
	return "bookEdit";
}

public String edit() throws Exception {
	System.out.println("edit方法...");
	return "bookEdit";
}

public String list() throws Exception {
	System.out.println("list方法...");
	System.out.println(user1);
	System.out.println(user2);
	System.out.println(sex);
	HttpServletRequest request = ServletActionContext.getRequest();
	request.setAttribute("age", 12);
	req.setAttribute("hobby", "ccc");
	return "bookEdit";
}

public User getModel() {
	return user1;
}

@Override
public void setServletResponse(HttpServletResponse arg0) {
   this.resp = arg0;	
}

@Override
public void setServletRequest(HttpServletRequest arg0) {
	this.req = arg0;
	
}



}

 

运行结果

Modeldrier接口传参

 

set方法传参

 通过对象属性传参

 四、Struts与Tomcat的集成

方法：实现接口

① Demo1Action 继承ActionSupport 实现ModelDriven,ServletRequestAware,ServletResponseAware
②重写ServletRequestAware,ServletResponseAware方法
 

package com.hpw.one.web;

import javax.servlet.ServletRequest;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

import com.hpw.one.entity.User;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class Demo1Action extends ActionSupport implements ModelDriven,ServletRequestAware,ServletResponseAware{
	
	private HttpServletRequest req;
	private HttpServletResponse resp;
	private User user1 = new User();
	private String sex;
	private User user2;
	
public User getUser1() {
		return user1;
	}

	public void setUser1(User user1) {
		this.user1 = user1;
	}

	public User getUser2() {
		return user2;
	}

	public void setUser2(User user2) {
		this.user2 = user2;
	}

public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

public String list() throws Exception {
	System.out.println("list方法...");
	System.out.println(user1);
	System.out.println(user2);
	System.out.println(sex);
	HttpServletRequest request = ServletActionContext.getRequest();
	request.setAttribute("age", 12);
	req.setAttribute("hobby", "ccc");
	return "bookEdit";
}

public User getModel() {
	return user1;
}

@Override
public void setServletResponse(HttpServletResponse arg0) {
   this.resp = arg0;	
}

@Override
public void setServletRequest(HttpServletRequest arg0) {
	this.req = arg0;
	
}



}

bookEdit.jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>







成功界面----------------
${age }
${hobby }

运行结果

到这里就结束了，欢迎大佬指点
