maven搭建WEB项目4 - 添加springmvc

    1、添加springmvc的依赖，在pom.xml中添加
   

<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-webmvc</artifactId>
		</dependency>
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-core-asl</artifactId>
		</dependency>
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-mapper-asl</artifactId>
		</dependency>
		<dependency>
			<groupId>org.codehaus.jackson</groupId>
			<artifactId>jackson-jaxrs</artifactId>
		</dependency>

    2、在web.xml中注册springmvc
   

<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:applicationContext-web.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

    3、配置springmvc
    在classpath中添加applicationContext-web.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
	   http://www.springframework.org/schema/context 
	   http://www.springframework.org/schema/context/spring-context-3.0.xsd  
	   http://www.springframework.org/schema/mvc 
	   http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 
	   http://www.springframework.org/schema/tx 
	   http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 
	   http://www.springframework.org/schema/util 
	   http://www.springframework.org/schema/util/spring-util-3.0.xsd">

	<!-- Spring 3.0 configuration -->
	<mvc:annotation-driven />

	<!-- Allows for mapping the DispatcherServlet to "/" by forwarding staticresource requests to the container's default Servlet -->
	<mvc:default-servlet-handler />

	<mvc:view-controller path="/" view-name="index" />

	<!-- 总错误处理-->
	<bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
		<property name="defaultErrorView">
			<value>/error/error</value>
		</property>
		<property name="defaultStatusCode">
			<value>500</value>
		</property>
		<property name="warnLogCategory">
			<value>org.springframework.web.servlet.handler.SimpleMappingExceptionResolver
			</value>
		</property>
	</bean>

	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp"></property>
	</bean>

	<context:component-scan base-package="pine.web.controller"/>
	
</beans>

    4、编写Controller类

@Controller
@RequestMapping("home")
public class HomeController {
	
	@RequestMapping("load")
	public String load() {
		return "home";
	}

}

    5、编写JSP
    在WEB-INF下添加jsp文件夹，并在jsp文件夹中新增一个home.jsp

    6、修改SS的FORM-LOGIN配置

<form-login login-page="/login.jsp"
			authentication-failure-url="/login.jsp?error=true"
			default-target-url="/home/load" always-use-default-target="true" />
		<logout logout-success-url="/login.jsp" />

    其中default-target-url意思是登陆成功后指向的URL，记得去掉http标签中的auto-config="true"的配置项，这样系统在登陆之后就直接会直接转向/home/load这个路径，经由springmvc，将指向/WEB-INF/jsp/home.jsp页面

    7、测试一下

    经过多次修改之后整个的项目的目录结构如下
