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

springmvc数据绑定出的错

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。
查看一下你传的参数是不是有date类型等Springmvc不支持参数绑定的类型，需自己绑定

date时间类型绑定 String-->date

String--> date 时间格式

 1 package com.online.util;
 2
 3 import java.text.ParseException;
 4 import java.text.SimpleDateFormat;
 5 import java.util.Date;
 6 import java.util.Locale;
 7
 8 import org.springframework.format.Formatter;
 9
10 public class DateFormatter implements Formatter<Date>{
11
12
13     public String print(Date object, Locale locale) {
14         return null;
15     }
16
17     public Date parse(String text, Locale locale) throws ParseException {
18         SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
19         Date date = null;
20         try {
21             date = format.parse(text);
22         } catch (Exception e) {
23             format = new SimpleDateFormat("yyyy-MM-dd");
24             date = format.parse(text);
25         }
26         return date;
27     }
28 }

在Spring的applicationContext.xml中注入这个类

1 <!-- 时间类型转换 -->
2     <bean id="conversionService"
3         class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
4         <property name="formatters">
5             <set>
6                 <bean class="com.online.util.DateFormatter"></bean>
7             </set>
8         </property>
9     </bean>

在Springmvc.xml中使用 mvc:annotation-driven注解配置

1 <mvc:annotation-driven conversion-service="conversionService"/>

这样就是现了string-->date类型的转换
