SimpleFormController提交表单流程例如以下：

**login.jsp**

**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>

**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);
    	}
    }
