springmvc初步配置

1. 导包/添加依赖：

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-aop</artifactId>

<version>4.0.2.RELEASE</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-beans</artifactId>

<version>4.0.2.RELEASE</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-context</artifactId>

<version>4.2.2.RELEASE</version>

<type>pom.lastUpdated</type>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-core</artifactId>

<version>4.0.2.RELEASE</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-tx</artifactId>

<version>4.0.2.RELEASE</version>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-webmvc</artifactId>

<version>4.0.2.RELEASE</version>

</dependency>

2.web.xml文件配置

<!-- 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:spring-mvc.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.上面配置里面classpath:spring-mvc.xml，所以去创建一个spring-mvc.xml文件

注意位置是直属resources

里面配置

<!-- 启用spring mvc 注解 -->

<context:annotation-config/>

<!-- 配置扫描controller包 -->

<context:component-scan base-package="test.tt.controller.*" />

<!-- 完成请求和注解POJO的映射 -->

<bean  class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->

<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver"

p:prefix="/WEB-INF/views/" p:suffix=".jsp" />

4.根据位置创建包和类，来自这里

<context:component-scan base-package="test.tt.controller.*" />

5.创建返回的页面

页面位置来自：p:prefix="/WEB-INF/views/"

页面类型/后缀：p:suffix=".jsp"

页面名称：return new ModelAndView("test")这个返回的字符串；

6.修改欢迎界面，

7.启动测试

8.乱码解决：在index界面加上，这里是网页读取信息，没走拦截器，web.xml不管用

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

pageEncoding="UTF-8"%>

9.点击超链

ps:如果出现一个no fondPage 和no mapping的错误，就把web.xml的协议头换下

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"></web-app>
