struts的初步使用

目标：

一：struts的配置

二：struts的动态方法调用

三：struts的传参

四：struts与tomcat的集成

一：struts的配置

第一步：导依赖（pom.xml）

首先在左侧菜单栏右键

 然后点击Maven Project,再点击Next

  继续Next

  然后Catalog选择Internal,Filter选择最后一个，然后继续Next

 然后Group Id为包名，Artifact Id为项目名，然后Finish

 

 

 然后这一步还需要将jar包改为1.8

修改pom.xml

  4.0.0
  com.lj
  Lj_hibernate
  war
  0.0.1-SNAPSHOT
  Lj_hibernate Maven Webapp
  http://maven.apache.org
  
   
			javax.servlet
			javax.servlet-api
			4.0.1
			provided
		
  
  
    Lj_hibernate
    
    
				org.apache.maven.plugins
				maven-compiler-plugin
				3.7.0
				
					1.8
					1.8
					UTF-8
				
			
    
  

 右键项目找到Poperties 

 点击Project Facets,将Java改为1.8

 两个方法都是修改jar，将Dynamic Web Module改为3.1，然后点击黄色条里面的链接

将Content directory改为src/mainwebapp就可以了

 

 然后添加依赖

依赖：

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

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  4.0.0
  com.lj
  T269_struts
  war
  0.0.1-SNAPSHOT
  T269_struts Maven Webapp
  http://maven.apache.org
 
   
            javax.servlet
            javax.servlet-api
            4.0.1
            provided
        
        
            org.apache.struts
            struts2-core
            2.5.13
        
 
 
    T269_struts
   
   
                org.apache.maven.plugins
                maven-compiler-plugin
                3.7.0
                
                    1.8
                    1.8
                    UTF-8
                
            
   
 

 

第二步：做配置（配置过滤器）

首先找到web.xml

修改成：

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

 注意：maven项目的结构

 第三步：框架配置文件

将（struts-base.xml、struts-sy.xml、struts.xml）放入src/main/resources中

 struts-base.xml

	
	
	
	
	
 
	
		regex:.*
	

  struts-sy.xml

 struts.xml

第四步：开发写web层

首先创建一个web层（Demo1Action）

package com.lj.one.web;
 
import com.opensymphony.xwork2.ActionSupport;
 
public class Demo1Action extends ActionSupport{
	public String add() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("add方法、、、");
		return "bookEdit";
	}
	public String del() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("del方法、、、");
		return "bookEdit";
	}
	public String edit() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("edit方法、、、");
		return "bookEdit";
	}
 
}

然后创建两个页面

bookEdit

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







成功界面
 

demo1

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







	struts动态方法调用
	新增

	修改

	删除

然后写配置

	
	
		
			/bookEdit.jsp
		
	

 使用{2}方法

	
	
		
			/{2}.jsp
		
	

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







	struts动态方法调用
	新增

	修改

	删除

	新增

结果：

这个时候前三个点击就会报错了，因为后面那里没有改为第二种方法

三：struts的传参

 1：ModelDriver接口传参

 新建一个实体类

package com.lj.one.entity;
 
public class User {
	private String uid;
	private String uname;
	public String getUid() {
		return uid;
	}
	public void setUid(String uid) {
		this.uid = uid;
	}
	public String getUname() {
		return uname;
	}
	public void setUname(String uname) {
		this.uname = uname;
	}
	@Override
	public String toString() {
		return "User [uid=" + uid + ", uname=" + uname + "]";
	}
	
 
}

实现模型驱动接口

package com.lj.one.web;
 
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.lj.one.entity.User;
 
public class Demo1Action extends ActionSupport implements ModelDriven{
	private User user1=new User();
	
	public String add() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("add方法、、、");
		return "bookEdit";
	}
	public String del() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("del方法、、、");
		return "bookEdit";
	}
	public String edit() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("edit方法、、、");
		return "bookEdit";
	}
	public String list() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("list方法、、、");
		System.out.println(user1);
		return "bookEdit";
	}
	@Override
	public User getModel() {
		// TODO Auto-generated method stub
		return user1;
	}
 
}

demo1.jsp

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







	struts动态方法调用
	新增

	修改

	删除

	新增

	struts的传参
	ModelDriver接口传参

	set属性传参

	通过对象属性传参

运行结果：

 

 

二：set属性传参

在子控制器新建一个sex

package com.lj.one.web;
 
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.lj.one.entity.User;
 
public class Demo1Action extends ActionSupport implements ModelDriven{
	private User user1=new User();
	private String sex;
	
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String add() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("add方法、、、");
		return "bookEdit";
	}
	public String del() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("del方法、、、");
		return "bookEdit";
	}
	public String edit() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("edit方法、、、");
		return "bookEdit";
	}
	public String list() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("list方法、、、");
		System.out.println(user1);
		System.out.println(sex);
		return "bookEdit";
	}
	@Override
	public User getModel() {
		// TODO Auto-generated method stub
		return user1;
	}
 
}

demo1.xml

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







	struts动态方法调用
	新增

	修改

	删除

	新增

	struts的传参
	ModelDriver接口传参

	set属性传参

	通过对象属性传参

结果展示：

 

三：通过对象属性传参

新建一个对象

package com.lj.one.web;
 
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.lj.one.entity.User;
 
public class Demo1Action extends ActionSupport implements ModelDriven{
	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 {
		// TODO Auto-generated method stub
		System.out.println("add方法、、、");
		return "bookEdit";
	}
	public String del() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("del方法、、、");
		return "bookEdit";
	}
	public String edit() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("edit方法、、、");
		return "bookEdit";
	}
	public String list() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("list方法、、、");
//		System.out.println(user1);
		System.out.println(sex);
		System.out.println(user2);
		return "bookEdit";
	}
	@Override
	public User getModel() {
		// TODO Auto-generated method stub
		return user1;
	}
 
}

demo1.xml

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







	struts动态方法调用
	新增

	修改

	删除

	新增

	struts的传参
	ModelDriver接口传参

	set属性传参

	通过对象属性传参

结果展示： 

四： struts与tomcat的集成

 

然后在bookEdit中调用

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







成功界面
${age}

方法二：

实现ServletRequestAware,ServletResponseAware接口

package com.lj.one.web;
 
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.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.lj.one.entity.User;
 
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 {
		// TODO Auto-generated method stub
		System.out.println("add方法、、、");
		return "bookEdit";
	}
	public String del() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("del方法、、、");
		return "bookEdit";
	}
	public String edit() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("edit方法、、、");
		return "bookEdit";
	}
	public String list() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("list方法、、、");
//		System.out.println(user1);
		System.out.println(sex);
		System.out.println(user2);
		HttpServletRequest request = ServletActionContext.getRequest();
		request.setAttribute("age", 12);
		req.setAttribute("hobby", "xp");
		return "bookEdit";
	}
	@Override
	public User getModel() {
		// TODO Auto-generated method stub
		return user1;
	}
	@Override
	public void setServletResponse(HttpServletResponse response) {
		// TODO Auto-generated method stub
		this.resp=response;
	}
	@Override
	public void setServletRequest(HttpServletRequest request) {
		// TODO Auto-generated method stub
		this.req=request;
	}
 
}
