1使用maven構建一war工程

在pom.xml中配置tomcat外掛

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>yirenbaomanagerweb</artifactId>
  <packaging>war</packaging>
  
  <build>  
    <pluginManagement>  
        <plugins>  
            <!-- 配置Tomcat外掛 -->  
            <plugin>  
                <groupId>org.apache.tomcat.maven</groupId>  
                <artifactId>tomcat7-maven-plugin</artifactId>  
                <version>2.2</version>  
                <configuration>  
                    <port>8085</port>  
                    <path>/</path>  
                </configuration>  
            </plugin>  
        </plugins>  
    </pluginManagement>  
  </build>  
</project>

	<servlet-mapping>

	</servlet-mapping>
</web-app>
 

接下來還需要一個spring-MVC配置檔案和一個Controller,加一個目標頁面

spring-MVC.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-4.3.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">

	<context:component-scan base-package="com.qx"></context:component-scan>
	
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- <property name="prefix" value="/"></property> -->
		<property name="suffix" value=".jsp"></property>
	</bean>
	
	<!-- 配置resource標籤,此標籤內部的地址不會被攔截 -->
	<mvc:resources location="/css/" mapping="/css/**"></mvc:resources>
	<mvc:resources location="/script/" mapping="/script/**"></mvc:resources>
	<mvc:resources location="/images/" mapping="/images/**"></mvc:resources>

	<mvc:annotation-driven></mvc:annotation-driven>
</beans>
 

package com.qx.manager.controller;

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

@Controller
public class PageController {

	/**
	 * 返回值 字串,如果沒有加 responsebody註解,則代表返回值是一個頁面的名字
	 * 如果以/開頭,代表是自根路徑開始找這個頁面
	 * 如果不是/開頭,它是自瀏覽器最後一個/開始替換掉後面的內容
	 * 如果是以redirect開頭,代表是重定向,重定向這樣寫只能重定向到專案內部的頁面
	 * 如果想要重定向到另外網站的頁面,需要在地址前面新增http://  也就是目標頁面的全路徑
	 * 
	 * @param page
	 * @return
	 */
	@RequestMapping("/page/{page}") //把這個請求引數page取出來的值{page}當做引數傳到getPage方法中賦給形參page
	public String getPage(@PathVariable("page") String page){
		return "/"+page;
	}
}

再在webapp下寫一個頁面hehe.jsp

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

呵呵噠
<script type="text/javascript">

</script>

使用rest風格,在位址列中輸入請求地址:  localhost:8085/page/hehe 時,  可以看到服務端給瀏覽器返回了一個頁面就是咱們的hehe.jsp

雖然我在hehe.jsp頁面中沒有寫<html>,<head>,<body>等標籤,但當瀏覽器解析的時候你一定會發現這些標籤一個都沒少.全都有
