视图解析

视图解析器	描述
FreeMarkViewResolver	将视图解析为FreeMarker模板
InternalResourceViewResolver	将视图解析为Web应用的内部资源(*.jsp)
VelocityViewResolver	将视图解析为Velocity布局,Velocity模板

InternalResourceViewResolver

@Bean
	public ViewResolver viewResolver(){
		InternalResourceViewResolver resourceViewResolver=new InternalResourceViewResolver();
		resourceViewResolver.setPrefix("/WEB-INF/views/");
		resourceViewResolver.setSuffix(".jsp");
		//加入Spring标签支持
		resourceViewResolver.setViewClass(org.springframework.web.servlet.view.JstlView.class);
		resourceViewResolver.setExposeContextBeansAsAttributes(true);
		return resourceViewResolver;
	}

SpringForm标签库

<%@ taglib uri="http://www.springframework.org/tags/form" prefix="sf" %>
<!--commandName 已经被Spring去掉了 新特性是modelAttribute-->
<sf:form method="post" modelAttribute="spitter">
	Fist Name: <sf:input path="firstName"></sf:input> <br/>
	<span  id="firstNameError">	<sf:errors path="firstName"/></span>
	Last Name: <sf:input path="lastName"></sf:input> <br/>
	email: <sf:input path="email"></sf:input> <br/>
	username: <sf:input path="username"></sf:input> <br/>
	password: <sf:input path="password"></sf:input> <br/>
	<input type="submit" value="Register">
</sf:form

Spring通用标签库

<%@ taglib uri="http://www.springframework.org/tags" prefix="s" %>
<!--可以让url携带参数 javaScriptEscape属性为true可以在js中使用-->
<s:url href="/spittles/{username}" var="spittlesUrl" javaScriptEscape="true">
<s:param name="max" value="60">
<s:param name="count" value="20">
<s:param name="username" value="wz">
</s:url>
<!--转义html-->
<s:escapeBody javaScriptEscape="true"><h1>Hello</h1></s:escapeBody>

JSP标签	描述
<s:escapeBody>	将标签中的内容进行HTML或JavaScript转义
<s:eval>	计算符合Spring表达式语言（SpEl）
