SimpleFormController提交表单流程如下：

login.jsp

<form action="login" method="post">
用户名：<input type="text" name="username"/></br>
密码：<input type="password" name="password"/></br>
<input type="submit" value="提交">
</form>

<form action="login" method="post">
	用户名：<input type="text" name="username"/></br>
	密码：<input type="password" name="password"/></br>
	<input type="submit" value="提交">
</form>

springMVC.xml

<bean name="/login" class="com.itmyhome.Login">
<property name="successView" value="success"/>
</bean>
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>

<!-- 处理器 -->
<bean name="/login" class="com.itmyhome.Login">
	<!-- 返回处理成功页面  success.jsp -->
	<property name="successView" value="success"/>
</bean>

<!-- HandlerMapping -->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<!-- HandlerAdapter -->
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>

<!-- 定义跳转的文件的前后缀 -->
<bean id="viewResolver"
	class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/" />  <!-- 默认放在WebRoot下 -->
	<property name="suffix" value=".jsp" /> 
</bean>
