Spring中AbstractCommandController控制器
定义继承AbstractCommandController的控制器，实现数据的自动封装
Controller
[java]
package com.hsit.controller;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.config.CustomEditorConfigurer;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.validation.BindException;
import org.springframework.web.bind.ServletRequestDataBinder;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;
import com.hsit.pojo.UserInfo;
public class UserInfoController extends AbstractCommandController {
@Override
protected ModelAndView handle(HttpServletRequest request,
HttpServletResponse response, Object command, BindException errors)
throws Exception {
// TODO Auto-generated method stub
UserInfo user = (UserInfo) command;
System.out.println(user);
return null;
}
}
JavaBean
[java]
package com.hsit.pojo;
import java.util.Date;
public class UserInfo {
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;
}
@Override
public String toString() {
return "username=" + username + ",password=" + password;
}
}

<form action="Login.do" method="post">
用户名：<input type="text" name="username" size="20"/><br>
账 号：<input type="password" name="password" size="20"><br>
<!--name名字一定要和UserInfo的属性名一样，才能正确封装-->
<input type="submit" value="提交">
</form>

配置如下

<!-- 配置处理器映射采用SimpleUrlHandlerMapping -->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<!-- props底下的prop标签内填写的key都是符合转发条件的url值，之后跟的是bean的ID，
如果输入的url值与key值中的url匹配，则执行对应beanID绑定的Controller -->
<props>
<prop key="go.do">go</prop>
<prop key="test.do">test</prop>
<prop key="goLogin.do">goLogin</prop>
<prop key="Login.do">Login</prop>
</props>

</bean>
<!-- 配置视图解释器 -->
<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass" val
补充：软件开发 , Java ,
