一，struts的配置
????????导入jar包也就是maven的pom.xml
pom.xml
? ?
导入相关的依赖 会自动出现这些jar包
????????web.xml配置中央控制器也就是过滤器
<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>Archetype Created Web Application</display-name>
?? ?<filter>
?? ??? ?<filter-name>struts</filter-name>
?? ??? ?<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
?? ?</filter>?? ?<filter-mapping>
?? ??? ?<filter-name>struts</filter-name>
?? ??? ?<url-pattern>*.action</url-pattern>
?? ?</filter-mapping>
</web-app>
?
?
? ? ? 写子控制器继承ActionSupport
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
?? ?"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
?? ?"http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
?? ?<!-- 引入struts的默认配置 -->
?? ?<include file="struts-default.xml"></include>
?? ?<!-- 对struts框架的基本配置 -->
?? ?<include file="struts-base.xml"></include>
?? ?<!-- 项目涉及到模块，分文件管理 -->
?? ?<include file="struts-sy.xml"></include>
</struts>
http://locahost:8080/mvc/xxx.action?methodName=list;
http://locahost:8080/mvc/order/xxx.action
http://locahost:8080/mvc/book/xxx.action
二，struts的动态方法调用
子控制器
?配置
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
?? ?"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
?? ?"http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>{1}只的是调用第一个方法
?? ?<package name="sy" extends="base" namespace="/sy">
?? ??? ?<action name="/demo1_*" class="com.hmf.one.web.Demo1Action" method="{1}">
?? ??? ??? ?<result name="bookEdit">/bookEdit.jsp</result>
?? ??? ?</action>
?? ?</package>
</struts>
jsp
效果?
?
?
三，struts的传参
自定义mvc ：
????????Modeldriver接口传参
struts：
????????①Modeldriver接口传参
public class Demo1Action extends ActionSupport implements ModelDriven<User>{
?? ?
private User user1=new User();public String list() throws Exception {
?? ??? ?System.out.println("list方法");
?? ??? ?System.out.println(user1);
?? ??? ?return "bookEdit";
?? ?}?
?? ?public User getModel() {
?? ??? ?return user1;
?? ?}}
实体类?
<h2>struts传参</h2>
?? ?<a href="${pageContext.request.contextPath }/sy/demo1_list.action?uid=001&&uname=zs">Modeldriver接口传参</a><br>
?
效果
?
?
? ? ? ? ②set传参
?? ?private String sex;
?? ?public String getSex() {
?? ??? ?return sex;
?? ?}System.out.println(sex);
?? ?<a href="${pageContext.request.contextPath }/sy/demo1_list.action?sex=nv">set传参</a><br>
效果
?
? ? ? ? ③通过对象属性传参
?? ?private User user2;
?? ?<a href="${pageContext.request.contextPath }/sy/demo1_list.action?user1.uid=002&&user2.uname=hmf">对象属性传参</a><br>
效果
四，struts与tomcat的集成
方法一：
?
效果
?方法二：
子控制器
package com.hmf.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.hmf.one.entity.User;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;public class Demo1Action extends ActionSupport implements ModelDriven<User>,ServletRequestAware,ServletResponseAware{
?? ?private HttpServletResponse resp;
?? ?private HttpServletRequest req;
?? ?
?? ?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 edit() throws Exception {
?? ??? ?System.out.println("edit方法");
?? ??? ?return "bookEdit";
?? ?}
?? ?
?? ?public String del() throws Exception {
?? ??? ?System.out.println("del方法");
?? ??? ?return "bookEdit";
?? ?}
?? ?
?? ?public String list() throws Exception {
?? ??? ?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", 18);
?? ??? ?req.setAttribute("hobby", "唱歌");
?? ??? ?return "bookEdit";
?? ?}
?? ?
?? ?public User getModel() {
?? ??? ?return user1;
?? ?}?? ?public void setServletResponse(HttpServletResponse response) {
?? ??? ?this.resp=response;
?? ?}?? ?public void setServletRequest(HttpServletRequest request) {
?? ??? ?this.req=request;
?? ?}
}
