Spring MVC的3.1例外：一个错误/ BindingResult参数预期模型属性参数后，立即

我升级到春天3.1.1.RELEASE，现在我得到以下方法例外：

@RequestMapping(method = RequestMethod.POST, params = "_finish")
public ModelAndView doPostFinish(@PathVariable("runEnvironmentName") RunEnvironment pEnvironment, @ModelAttribute("command") JobSpecNewCommand pCommand, BindingResult pErrors) 
{
...
}

抛出以下异常：

java.lang.IllegalStateException: An Errors/BindingResult argument is expected 
to be immediately after the model attribute argument in the controller method 
signature: 

java.lang.IllegalStateException: An Errors/BindingResult argument is expected to be immediately after the model attribute argument in the controller method signature: public org.springframework.web.servlet.ModelAndView de.wwag.infra.oocsd.projectAdmin.fe.natures.hudson.jobspecs.RunEnvJobSpecNewController.doPostFinish(de.wwag.infra.oocsd.projectAdmin.common.domain.RunEnvironment,de.wwag.infra.oocsd.projectAdmin.fe.natures.hudson.jobspecs.JobSpecNewCommand,org.springframework.validation.BindingResult)
    at org.springframework.web.method.annotation.ErrorsMethodArgumentResolver.resolveArgument(ErrorsMethodArgumentResolver.java:62) ...

正如你所看到的方法签名是符合市场预期。该BindingResult参数模型属性后声明。

在同一类中的以下方法声明：

@ModelAttribute("otherJobSpecs")
public List<JobReference> modelOtherJobSpecs(@PathVariable("runEnvironmentName") RunEnvironment pEnvironment, @ModelAttribute("command") JobSpecNewCommand pCommand) 
{
...
}

当我从类中删除的方法，一切正常。

有任何想法吗？

Answer 1:

这是一个在春天有个错误，我报告说，它： SPR-9378 。

Answer 2:

读春错误SPR-9378，你必须删除从@ModelAttribute方法的模型变量：

@ModelAttribute
public void populateModel(Model model) { //this method haven't Libro Object
    model.addAttribute(Genero.values());
    model.addAttribute(EstadoLibro.values());
}

@RequestMapping(method=RequestMethod.POST)
public String grabarLibro(@Validated @ModelAttribute Libro libro, BindingResult result) {
   ...
}

它为我工作。
