1.新建web project
2.右键项目,给项目添加spring框架如图,不需要勾选任何一个选项。
3.在WebRoot/WEB-INF目录下添加web.xml内容如下:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<!--configure the setting of springmvcDispatcherServlet and configure the mapping-->
<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:springmvc-servlet.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>
</web-app>
servlet模块添加了springmvc的调度器,如果需要改springmvc的配置文件的名字,可以更改springmvc-servlet.xml这个名字为指定名字。
servlet-mapping连接了这个servlet,并能够定义url-pattern,一般使用/而不是/*。
4.在src目录下添加springmvc-servlet.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:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
<!-- scan the package and the sub package -->
<context:component-scan base-package="com.controller"/>
<!-- don't handle the static resource -->
<mvc:default-servlet-handler />
<!-- if you use annotation you must configure following setting -->
<mvc:annotation-driven />
<!-- configure the InternalResourceViewResolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>
base-package指定你的controller所在的包,prefix和suffix分别指定了view所在的位置和后缀,这个配置文件连接了controller和view。
5.新建controller,所在包应为springmvc-servlet.xml中指定的base-package
结构如下:
内容如下:
package com.controller; import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping; @Controller
@RequestMapping("/Hello")
public class HelloController {
@RequestMapping("/hello")
public String hello(){
return "hello";
}
}
6.新建view,所在位置应为springmvc-servlet.xml中的prefix,后缀为指定后缀,名称与controller中返回的字符串相同。
内容自拟。
至此,一个springmvc的hello world项目配置完毕。
