SimpleFormController提交表单流程例如以下：

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=http://www.mamicode.com/"提交">>
springMVC.xml
<!-- 处理器 -->
<bean name="/login" class="com.itmyhome.Login">
	<!-- 返回处理成功页面  success.jsp -->
	<property name="successView" value=http://www.mamicode.com/"success"/>>
UserModel.java
public class UserModel {
	private String username;
	private String password;

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}
}

Login.java
import org.springframework.web.servlet.mvc.SimpleFormController;

public class Login extends SimpleFormController {
	public Login() {
		setCommandClass(UserModel.class);// 设置命令对象实现类
		setCommandName("user");// 设置命令对象的名字
	}
	//下面内容省略
	/*protected Object formBackingObject(HttpServletRequest request) throws Exception { 
		return null;
	} 
	protected Map referenceData(HttpServletRequest request) throws Exception { 
		return null;
	}*/
	public void doSubmitAction(Object obj) throws Exception {
		UserModel user = (UserModel) obj;
		System.out.println(user);
	}
}

success.jsp
