springmvc 配置01

springmvc请求流程与struts比较

 

1.添加包

com.springsource.org.aopalliance-1.0.0.jar
com.springsource.org.apache.commons.logging-1.1.1.jar
spring-aop-3.2.2.jar
spring-aspects-3.2.2.jar
spring-beans-3.2.2.jar
spring-context-3.2.2.jar
spring-context-support-3.2.2.jar
spring-core-3.2.2.jar
spring-expression-3.2.2.jar
spring-web-3.2.2.jar
spring-webmvc-3.2.2.jar

  <dependencies>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
    </dependency>

    <dependency>
        <groupId>org.aopalliance</groupId>
        <artifactId>com.springsource.org.aopalliance</artifactId>
        <version>1.0.0</version>
    </dependency>

    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>com.springsource.org.apache.commons.logging</artifactId>
        <version>1.1.1</version>
    </dependency>

     <!-- 添加spring依赖 -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aop</artifactId>
        <version>4.3.5.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
        <version>4.3.5.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>

    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.3.5.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>4.3.5.RELEASE</version>
    </dependency>

  </dependencies>

2.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>springmvc</display-name>

  <servlet>
        <servlet-name>action</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>action</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3.在src/main/resources 配置 spring-mvc.xml 名字要与web.xml中的 classpath:后面的保持一致就可以了

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">

<!--     handdlerMapping 如果没有写 默认是 BeanNameUrlHandlerMapping -->
<!--         映射分为3种，BeanNameUrlHandlerMapping、simpleUrlHandlerMapping、controllerClassNameHandlerMapping -->
<!--     property name="order" value="1" 用于排序哪种优先级高，数字越小优先级越高 -->
    <!-- 处理器映射 -->
    <!-- BeanNameUrl处理器映射 -->
    <bean id="beanNameUrlHandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">
        <property name="order" value="1"/>
    </bean>
    <!-- SimpleUrl处理器映射， 多个不同的url转到同个action请求的情况 -->
    <bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/hi.action">hc</prop>
                <prop key="/a.action">hc</prop>
                <prop key="/b.action">hc</prop>
                <prop key="/c.action">hc</prop>
            </props>
        </property>
        <property name="order" value="0"/>
    </bean>
    <!-- ControllerClassName处理器映射 -->
<!--     根据类名请求url，类名要小写，切记 -->
    <bean id="controllerClassNameHandlerMapping" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping">
        <property name="order" value="2"/>
    </bean>

    <!-- 控制器 -->
    <bean id="hc" name="/hi.action" class="com.shanheyongmu.controller.HomeController"/>
    <bean id="personCommandController" class="com.shanheyongmu.controller.PersonCommandController"/>
    <bean id="personFormController" class="com.shanheyongmu.controller.PersonFormController">
        <!-- 表单视图 -->
        <property name="formView" value="jPersonCreate"/>
        <!-- 成功视图 -->
        <property name="successView" value="index"/>
    </bean>
    <bean id="myWizardController" class="com.shanheyongmu.controller.MyWizardController">
        <property name="pages">
            <list>
                <value>wizard/jPersonBaseInfo</value>
                <value>wizard/jPersonEduInfo</value>
                <value>wizard/jPersonWorkInfo</value>
            </list>
        </property>
    </bean>

    <!-- 内部资源视图解析器  prefix + logicName + suffix /WEB-INF/jsps/ + index + .jsp-->
<!--     用于解析在controller 中return  ModelAndView中的视图名的拼凑 -->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 前缀 -->
        <property name="prefix" value="/WEB-INF/jsps/"/>
        <!-- 后缀 -->
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

4.HomeController.java

package com.shanheyongmu.controller;

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

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class HomeController extends AbstractController {

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest request,
            HttpServletResponse response) throws Exception {

        System.out.println("hello" + request.getContextPath() + request.getServletPath());

        return new ModelAndView("index");
    }

}

5 . index.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<html>
  <head>
    <title>My JSP 'index.jsp' starting page</title>
  </head>

  <body>

    This is my JSP page. spring MVC<br>
  </body>
</html>

spring-mvc.xml中包含3种handdlerMapping的配置 选择一种适合的
