1、项目介绍
利用Spring MVC控制器，返回网页和json.
2、新建Maven工程
3、配置pom.xml
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
4.0.0
com.nextgame
hellospring
war
0.0.1-SNAPSHOT
hellospring Maven Webapp
http://maven.apache.org
4.0.5.RELEASE
junit
junit
3.8.1
test
org.springframework
spring-core
${spring.version}
org.springframework
spring-web
${spring.version}
org.springframework
spring-webmvc
${spring.version}
hellospring
4、HelloSpring控制器
①导入servlet-api
从Tomcat的lib目录中导入servlet-api.jar②导入json-lib
（注：①②可以通过pom.xml添加依赖，请无视我手动导入的笨办法- -）③源码
package com.nextgame.web;
import java.io.IOException;
import net.sf.json.*;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import javax.servlet.http.*;
@Controller
public class HelloController {
@RequestMapping("/view")
//返回网页 public String hello(@RequestParam(value="hello", required=false, defaultValue="World") String name, Model model) { model.addAttribute("hello", name); return "helloworld"; }@RequestMapping("/json")//返回json public void json(HttpServletRequest req,HttpServletResponse res) throws IOException {JSONObject obj = new JSONObject();obj.put("msg", "hello spring");obj.put("copyright", "wang hao");res.getWriter().print(obj); }}
5、网页
在WEB-INF目录下新建views目录，在views目录下新建hello world.jsp<%@ page language="java" cOntentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>
Hello:${name}
6、配置Spring servlet
①命名规则：xxx-servlet.xml,这里命名为：dispatcher-servlet.xml
②配置
xmlns:cOntext="http://www.springframework.org/schema/context"
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-3.0.xsd">
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
/WEB-INF/views/
.jsp
7、配置web.xml
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
Archetype Created Web Application
dispatcher
org.springframework.web.servlet.DispatcherServlet
1
dispatcher
/
contextConfigLocation
/WEB-INF/dispatcher-servlet.xml
org.springframework.web.context.ContextLoaderListener
8、run as server
http://localhost:8080/hellospring/view
(囧：EL表达式请略过。。。)
http://localhost:8080/hellospring/json
