Java 例外情况：；处理程序没有适配器。您的处理程序是否实现了像控制器这样受支持的接口；,java,spring,hibernate,jsp,hibernate-validator,Java,Spring,Hibernate,Jsp,Hibernate Validator,我试图使用Spring和Hibernate验证JSP中的一个简单表单。JSP页面Temp.JSP如下所示（web.xml中的url pttern是*.htm）应该在其中处理验证的Controller类如下（我使用的是SimpleFormController）在DispatcherServlet中，我添加了以下内容 <bean id="tempService" class="usebeans.TempServiceImpl" /> <bean name="/Temp.htm"

我试图使用Spring和Hibernate验证JSP中的一个简单表单。JSP页面Temp.JSP如下所示（web.xml中的url pttern是

*.htm

）

应该在其中处理验证的

Controller

类如下（我使用的是

SimpleFormController

）

在DispatcherServlet中，我添加了以下内容

<bean id="tempService" class="usebeans.TempServiceImpl" />
<bean name="/Temp.htm" class="controller.Temp" p:tempService-ref="tempService" p:formView="Temp" p:successView="Temp" />

下面是

TempServiceImpl

类

package usebeans;

import validators.ValidationForm;

final public class TempServiceImpl implements TempService
{
    public void add(ValidationForm validationForm)
    {
        System.out.println("Message");
    }
}

尽管类

TempServiceImpl

实现了

TempService

接口，但我得到了以下异常

编辑：

尽管我遵循了解释，但问题仍然存在，我得到了与上面提到的相同的异常。我在这里缺少什么配置设置。它可能位于

dispatcherservlet.xml

文件中。整个

dispatcherservlet.xml

文件如下所示

使用哪个版本的spring？spring版本是

3.0.2

是否确实要使用

ControllerClassNameHandlerMapping

？您可以删除这个bean并重试一次吗？@Arun，应该删除哪个bean？

bean。然后它抛出一个新的异常

java.lang.IllegalStateException:BindingResult和作为请求属性可用的bean名称“validationForm”的普通目标对象都不表示该命令对象对控制器不可用。（JSP页面没有绑定到ValidationForm
类）。我完全按照您提到的那样修改了Temp控制器类，但不幸的是，它引发了与前面注释中提到的相同的异常。答案可能非常接近。我没有使用jsp。。。所以我认为我不能帮你解决绑定错误问题。。。但是你可以参考这个链接来看看它是如何实现的。如果你能通过带注释的spring mvc来简化spring编程…我们可以使spring配置更好。。。我现在有一些时间限制。。。我将尝试进行这些更改，稍后与您分享。。。
