Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

无法创建配置，因为找不到bean验证提供程序。添加一个提供者像Hibernate Validator（RI）到您的类路径。

这个错误是不影响项目运行的。是因为我修改了日志输出级别才看到这个错误，不然的话都看不到这个错误。

解决方法：

解决这个问题首先要了解一些概念！

JSRs: Java Specification Requests 即Java规范要求
它是Java标准化组织（Java Community Process）提交给sun的java开发草案。
对于实时应用都有对应的JSR，比如现在几乎不用的EJB，以前都有对应的JSR，它是一种对应应用的开发标准草案。即它都是对应现在的每个Java应用的，是一些工业标准。

JSR 303 - Bean Validation

JSR 303 – Bean Validation 是一个数据验证的规范，2009 年 11 月确定最终方案。2009 年 12 月 Java EE 6 发布，Bean Validation 作为一个重要特性被包含其中。本文将对 Bean Validation 的主要功能进行介绍，并通过一些示例来演示如何在 Java 开发过程正确的使用 Bean Validation。

关于 Bean Validation

在任何时候，当你要处理一个应用程序的业务逻辑，数据校验是你必须要考虑和面对的事情。应用程序必须通过某种手段来确保输入进来的数据从语义上来讲是正确的。在通常的情况下，应用程序是分层的，不同的层由不同的开发人员来完成。很多时候同样的数据验证逻辑会出现在不同的层，这样就会导致代码冗余和一些管理的问题，比如说语义的一致性等。为了避免这样的情况发生，最好是将验证逻辑与相应的域模型进行绑定。

Bean Validation 为 JavaBean 验证定义了相应的元数据模型和 API。缺省的元数据是 Java Annotations，通过使用 XML 可以对原有的元数据信息进行覆盖和扩展。在应用程序中，通过使用 Bean Validation 或是你自己定义的 constraint，例如 @NotNull, @Max, @ZipCode，就可以确保数据模型（JavaBean）的正确性。constraint 可以附加到字段，getter 方法，类或者接口上面。对于一些特定的需求，用户可以很容易的开发定制化的 constraint。Bean Validation 是一个运行时的数据验证框架，在验证之后验证的错误信息会被马上返回。

下载 JSR 303 – Bean Validation 规范 http://jcp.org/en/jsr/detail?id=303

Hibernate Validator 是 Bean Validation 的参考实现 . Hibernate Validator 提供了 JSR 303 规范中所有内置 constraint 的实现，除此之外还有一些附加的 constraint。如果想了解更多有关 Hibernate Validator 的信息，请查看 http://www.hibernate.org/subprojects/validator.html

参考IBM的一篇不错的文章：https://www.ibm.com/developerworks/cn/java/j-lo-jsr303/

添加jsr303-validation包或者添加maven包的依赖

<dependency>
<groupId>org.apache.bval</groupId>
<artifactId>bval-jsr303</artifactId>
<version>0.5</version>
</dependency>

我的项目：Spring 4.0.2 Maven 项目

所以我添加了包依赖，更新项目，重新启动，却出现了新的错误，出错不要紧，影响项目的正常运行和使用了。
