400 Bad Request The request sent by the client was syntactically incorrect ().

项目中一直出现400错误，后面搜索下，发现如下内容。

SpringMVC报错信息为The request sent by the client was syntactically incorrect ()

在数据绑定的时候一定要主意Controller方法中的参数名和jsp页面里的参数名字是否一致或者按照绑定的规范来写，如果不一致，可能回报如下错误： The request sent by the client was syntactically incorrect ().

从字面上理解是：客户端发送的请求语法错误。实际就是springmvc无法实现数据绑定。 

<input type="text" class="Wdate" id="start_date" name="start_date" value="${data.s_start_date}" 

修改也如下内容，就解决了

<input type="text" class="Wdate" id="s_start_date" name="s_start_date" value="${data.s_start_date}"
