	 */

	public ModelAndView showHello(){
		//创建模型和视图对象
		ModelAndView mv = new ModelAndView();
		//设置数据

	}

<form action="${pageContext.request.contextPath}/receiveInt.do">
		<input type="text" name="id" id="id" >
		<input type="submit" value="提交表单" >
</form>

	/**
	 * 需求:接受int类型参数
	 * springmvc参数封装方法:

	 */
	@RequestMapping("receiveInt")
	public String receiveInt(int id){
		System.out.println(id);

		return "success/success";
	}

	 */
	@RequestMapping("receiveBoolean")
	public String receiveBoolean(boolean flag){
		System.out.println(flag);
		//封装成功
		return "success/success";
	}

④、接收String类型参数（中文乱码的解决）

<form action="${pageContext.request.contextPath}/receiveStr.do">
		姓名：<input type="text" name="username" id="username" >		
		<br><input type="submit" value="提交表单" >
</form>

@RequestMapping("receiveStr")
	public String receiveStr(String username){
		System.out.println(username);
		//封装成功
		return "success/success";
	}

@RequestMapping("receiveStr")
	public String receiveStr(String username){
		try {
			username=new String(username.getBytes("iso8859-1"), "utf-8");
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		System.out.println(username);
		
		//封装成功
		return "success/success";
	}

<form action="${pageContext.request.contextPath}/receiveArray.do" method="post" >
		<input type="checkbox" name="ids" value="1" >篮球		
		<br><input type="checkbox" name="ids" value="2" >足球
		<br><input type="checkbox" name="ids" value="3" >乒乓球
		<br><input type="submit" value="提交表单" >
</form>

/**
	 * 接收数组参数类型
	 * 批量删除
	 */
	@RequestMapping("receiveArray")
	public String receiveArray(Integer[] ids){
		System.out.println(Arrays.toString(ids));
		//封装成功
		return "success/success";
	}

⑥、pojo类型传递（Date类型的格式）

<form action="${pageContext.request.contextPath}/receiveUser.do" method="post" >
		 姓名:<input type="text" name="username" id="username">
		 <br>性别:<input type="text" name="sex" id="sex">
		 <br>年龄:<input type="text" name="age" id="age">
		 <br>生日:<input type="text" name="birthday" id="birthday">
		 <br>地址:<input type="text" name="address" id="address"> 
		<br><input type="submit" value="提交表单" >
</form>

/**
	 * 需求:接受pojo类型参数
	 */
	@RequestMapping("receiveUser")
	public String receiveUser(User user){
		System.out.println(user);
		//封装成功
		return "success/success";
	}

      u默认的Date格式为1998/02/02

<form action="${pageContext.request.contextPath}/receiveVo.do" method="post" >
		 姓名:<input type="text" name="user.username" id="username">
		 <br>性别:<input type="text" name="user.sex" id="sex">
		 <br>年龄:<input type="text" name="user.age" id="age">
		 <br>生日:<input type="text" name="user.birthday" id="birthday">
		 <br>地址:<input type="text" name="user.address" id="address"> 
		<br><input type="submit" value="提交表单" >
</form>

<form action="${pageContext.request.contextPath}/receiveList.do" method="post" >
			 姓名:<input type="text" name="uList[0].username" id="username">
		 <br>地址:<input type="text" name="uList[0].address" id="address"> 
		 <br>姓名:<input type="text" name="uList[1].username" id="username">
		 <br>地址:<input type="text" name="uList[1].address" id="address"> 
		 
		<br><input type="submit" value="提交表单" >
	</form>

	/**
	 * 需求：时间类型参数，如果和当前系统时间类型不匹配，传递不成功
	 * 解决方案：使用注解
	 */
	@InitBinder
	public void dateRegister(WebDataBinder binder){//true表示可以为空
		binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true));
	}
