我在pom.xml中添加了下一个依赖项：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
</dependency>
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
因为我想在homeController中使用@Valid和BindingResult：
@RequestMapping(value = "/admin/productInventory/addProduct", method = RequestMethod.POST)
public String addProductPost(@Valid @ModelAttribute("productss") Product product, BindingResult result, HttpServletRequest request) {
if (result.hasErrors()) {
return "addProduct";
}
productDao.addProduct(product);
MultipartFile productImage = product.getProductImage();
String rootDirectory = request.getSession().getServletContext().getRealPath("/");
path = Paths.get(rootDirectory + "\\WEB-INF\\resources\\images\\" + product.getProductId() + ".png");
if (productImage != null & !productImage.isEmpty()) {
try {
productImage.transferTo(new File(path.toString()));
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException("Product image saving failed", e);
}
}
return "redirect:/admin/productInventory";
}
我得到以下错误：

有人可以告诉我问题是什么吗？ （我首先在pom.xml中将另一个版本添加到Hibernate Validator中......我不知道这是不是问题 - 我过去有一个类似的版本，并且有两个版本的重复导入，但是现在我已经看过了那里不是重复的）。我认为代码是正确的，问题在于依赖关系...如果我评论这部分（依赖关系，来自Model类的验证以及来自Controller的@Valid和BindingResult）代码工作正常......
尝试删除以下依赖项，然后尝试maven：clean build。
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
上面的依赖关系已经通过hibernate-validator包含导入了。
您确定产品的型号属性名称中有两个's'吗？
@ModelAttribute（“产品”）
