【JAVAWEB学习笔记】springmvc环境搭建

2015-02-16 11:09 239 查看
之前未曾真正做过java web相关的项目，最新学习了一下spring mvc框架

1.导入jar包



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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>

servlet-name 指定mapping的xml文件。要求文件的名字是springmvc-servlet.xml。

配置springmvc-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc" 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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 启动注解驱动的Spring MVC功能，注册请求url和注解POJO类方法的映射 -->
<mvc:annotation-driven />
<!-- 启动包扫描功能，以便注册带有@Controller、@Service、@repository、@Component等注解的类成为spring的bean -->
<context:component-scan base-package="str.controller" />
<!-- 对模型视图名称的解析，在请求时模型视图名称添加前后缀 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/page/"
p:suffix=".jsp" />
</beans>

3.编写Controller类
package str.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class MyController {
@RequestMapping(value = "/")
public String hello(){

return "index";
}

}


4.编写jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="<span style="font-family: Arial, Helvetica, sans-serif;">utf-8</span><span style="font-family: Arial, Helvetica, sans-serif;">"%></span>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=<span style="font-family: Arial, Helvetica, sans-serif;">utf-8</span><span style="font-family: Arial, Helvetica, sans-serif;">"></span>
<title>Insert title here</title>
</head>
<body>
<h1>hello</h1>
</body>
</html>




最后访问 127.0.0.1:8080/SpringMvc/

这个只是自己学习的笔记，不值得参考。
