Spring 4.3.5文档原文如下:

## 9.1 Introduction ##

**JSR-303/JSR-349 Bean Validation**

Spring Framework 4.0 supports Bean Validation 1.0 (JSR-303) and Bean Validation 1.1 (JSR-349) in terms of setup support, also adapting it to Spring’s `Validator` interface.

An application can choose to enable Bean Validation once globally, as described in [Section 9.8, “Spring Validation”][Section_9.8_ _Spring Validation], and use it exclusively for all validation needs.

An application can also register additional Spring `Validator` instances per `DataBinder` instance, as described in [Section 9.8.3, “Configuring a DataBinder”][Section_9.8.3_ _Configuring a DataBinder]. This may be useful for plugging in validation logic without the use of annotations.

Spring 4.x不需要在配置文件中配置Bean Validation验证,默认支持Bean Validation 1.1

所以只需要在pom.xml里添加依赖，在需要验证的属性上配置 annotation注解,在 Controller控制器中配置@Valid，最后通过检测BindingResult  hasErrors()方法验证是否通过
