使用Spring MVC3框架时，可能会遇到这个问题，请求后台没有任何响应，页面显示

让人很莫名其妙。

The request sent by the client was syntactically incorrect 说的意思是：由客户端发送的请求是语法上是不正确的。但还是不明白哪里出了问题，

我的URL[http://localhost:8080/mmsys/field/list.do?date=][http_localhost_8080_mmsys_field_list.do_date]2015-06-07,真看不出那个参数出错了，实在没办法我把spring日志级别调整到debug级别,终于找出原因了：

[DEBUG][2013/07/28 12:19:10,561]
    [org.springframework.web.servlet.mvc.annotation.ResponseStatusExceptionResolver] - Resolving exception from handler [com.xdtech.cloudsearch.module.config.index.action.FieldAction@44b46c4c]: 
    org.springframework.beans.TypeMismatchException:<span style="color:#ff6666;"> Failed to convert value of type 'java.lang.String' to required type 'java.util.Date'; nested exception is org.springframework.core.convert.ConversionFailedException: Unable to convert value "23-05-2013" from type 'java.lang.String' to type 'java.util.Date'; nested exception is java.lang.IllegalArgumentException
    </span>

Spring在转换日期出错了，翻看了一下spring-framework-reference.pdf找到下面这几行代码,加到自己的Action里，问题解决了：

@InitBinder
    	public void initBinder(WebDataBinder binder) {
    		SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    		dateFormat.setLenient(false);
    		binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false));
    	}
