springmvc初步配置
- 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>
