快速搭建SpringMVC4.0
快速搭建SpringMVC4.0
Spring MVC属于SpringFrameWork的后续产品，已经融合在Spring Web Flow里面。Spring 框架提供了构建 Web 应用程序的全功能 MVC 模块。使用 Spring 可插入的 MVC 架构，从而在使用Spring进行WEB开发时，可以选择使用Spring的SpringMVC框架或集成其他MVC开发框架，如Struts1，Struts2等。
接下来就为搭建搭建一个简单的MVC4.0
准备环境: jdk 1.7，tomcat7.0
新建项目: 新建Maven工程，在Archetype类型中，选择“maven-archetype-webapp”。

新建Controller类:
@Controller
public class HomeController {
@RequestMapping(value="/home")
public ModelAndView goHome(){
Map<String ,String> map = new HashMap<String, String>();
map.put("userName", "MVC4.1!");
return new ModelAndView("/view",map);
}
}
创建乱码处理类：
public class UTF8StringHttpMessageConverter extends AbstractHttpMessageConverter<String> {
public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");
private final List availableCharsets;
private boolean writeAcceptCharset = true;
public UTF8StringHttpMessageConverter() {
super(new MediaType("text", "plain", DEFAULT_CHARSET), MediaType.ALL);
this.availableCharsets = new ArrayList(Charset.availableCharsets().values());
}
/**
* Indicates whether the {@code Accept-Charset} should be written to any outgoing request.
* Default is {@code true}.
*/
public void setWriteAcceptCharset(boolean writeAcceptCharset) {
this.writeAcceptCharset = writeAcceptCharset;
}
@Override
public boolean supports(Class clazz) {
return String.class.equals(clazz);
}
@SuppressWarnings("rawtypes")
@Override
protected String readInternal(Class clazz, HttpInputMessage inputMessage) throws IOException {
Charset charset = getContentTypeCharset(inputMessage.getHeaders().getContentType());
return FileCopyUtils.copyToString(new InputStreamReader(inputMessage.getBody(), charset));
}
@Override
protected Long getContentLength(String s, MediaType contentType) {
Charset charset = getContentTypeCharset(contentType);
try {
return (long) s.getBytes(charset.name()).length;
}
catch (UnsupportedEncodingException ex) {
// should not occur
throw new InternalError(ex.getMessage());
}
}
@Override
protected void writeInternal(String s, HttpOutputMessage outputMessage) throws IOException {
if (writeAcceptCharset) {
outputMessage.getHeaders().setAcceptCharset(getAcceptedCharsets());
}
Charset charset = getContentTypeCharset(outputMessage.getHeaders().getContentType());
FileCopyUtils.copy(s, new OutputStreamWriter(outputMessage.getBody(), charset));
}
/**
* Return the list of supported {@link Charset}.
*
* By default, returns {@link Charset#availableCharsets()}. Can be overridden in subclasses.
*
* @return the list of accepted charsets
*/
protected List getAcceptedCharsets() {
return this.availableCharsets;
}
private Charset getContentTypeCharset(MediaType contentType) {
if (contentType != null && contentType.getCharSet() != null) {
return contentType.getCharSet();
}
else {
return DEFAULT_CHARSET;
}
}
} 创建/WEB-INF/views/view.jsp，用来展现数据:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Hellotitle>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
head>
<body>
hello ${userName }<br>
body>
html>启动项目访问对应的url就能看到页面上出现“hello MVC4.1!”的字样，说明你的springMVC4.1已经搭建完毕了！
