Errror提交客户端发送一个表单请求是语法不正确的弹簧DAO

起初有没有鉴定被命名为骆驼案件和下划线一些bean属性的问题。所以我删除了这些并重新生成了实体类。尽管现在已解决该问题，但在提交以下表单时，它会提供HTTP状态400错误“客户端发送的请求在语法上不正确”。虽然也有类似的问题，我找不到我的答案。Errror提交客户端发送一个表单请求是语法不正确的弹簧DAO

在区级

你有Adazone场。在JSP页面中你逝去的不是对象，而是一个Integer值，即=“$ {} result.adaid”

你能不能做以下修改，让我知道，如果这些为你工作。 在JSP页面传递一个对象，而不是一个整数

<c:forEach items="${adas}" var="result"> 
    <form:option value="${result}">${result.adaname}</form:option> 
</c:forEach>

然后，你必须声明两个转换器

public class IntegerToAdazone implements Converter<Integer, Adazone > { 

    @Override 
    public Adazone convert(Integer source) { 
     Adazone a = new Adazone(source); 
     return a; 
    } 

} 

public class AdazoneToInteger implements Converter<Adazone, Integer> { 

    @Override 
    public Integer convert(Adazone source) { 
     return source.getId(); 
    } 

}

然后你必须配置的转换服务。看看Spring文档http://docs.spring.io/spring/docs/current/spring-framework-reference/html/validation.html（9.5.5配置ConversionService）

默认ConversionService可以字符串，数字， 枚举，集合，地图和其他常见的类型之间的转换。为了补充或者 用您自己的自定义转换器覆盖默认转换器，请设置 转换器属性。属性值可以实现 Converter，ConverterFactory或GenericConverter接口中的任意一个。

<bean id="conversionService" 
     class="org.springframework.context.support.ConversionServiceFactoryBean"> 
    <property name="converters"> 
     <set> 
      <bean class="example.IntegerToAdazone"/> 
      <bean class="example.AdazoneToInteger"/> 
     </set> 
    </property> 
</bean>

更改包以上（实施例）作为合适的。 希望这会有所帮助
