The key statement of your stack trace is:
堆栈跟踪的关键语句是：
java.lang.AbstractMethodError: org.hibernate.validator.internal.engine.ConfigurationImpl.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider;
java.lang.AbstractMethodError: org.hibernate.validator.internal.engine.ConfigurationImpl.getDefaultParameterNameProvider()Ljavax/validation/ParameterNameProvider;
This answerseems also to apply to your problem description/exception message: You have a conflicting javax.validationversion!
此答案似乎也适用于您的问题描述/异常消息：您的javax.validation版本有冲突！
Hint:I prefer Netbeans' "Graph View" (of a pom editor) for identification & elimination of dependency conflicts (especially after some version upgrade). The "pure-maven-way" would be:
提示：我更喜欢 Netbeans 的“图形视图”（pom 编辑器的）用于识别和消除依赖冲突（尤其是在某些版本升级之后）。“纯行家方式”将是：
mvn dependency:tree -Dverbose -Dincludes=javax.validation

for my case, it was due to the spring mvc version from spring boot starter web not compatible with spring data. and the exception could be really tricky, where there are two constructors for AbstractMethodError, while the first one is default without any parameter. So depends on the implementation, if they throw exception using first constructor, would require a lot hard work for debugging.
就我而言，这是由于 spring boot starter web 中的 spring mvc 版本与 spring 数据不兼容。并且异常可能非常棘手，其中 AbstractMethodError 有两个构造函数，而第一个是没有任何参数的默认构造函数。所以取决于实现，如果他们使用第一个构造函数抛出异常，将需要大量的调试工作。

add hibernate validation dependency, I have used only Simple validation config.
添加休眠验证依赖项，我只使用了简单验证配置。
import org.springframework.validation.Validator;
Other Imports
@Configuration
@EnableWebMvc
@ComponentScan(basePackages= {"com.app"})
public class WebMvcConfig implements WebMvcConfigurer {
..........
@Override
public Validator getValidator() {
LocalValidatorFactoryBean validator = new LocalValidatorFactoryBean();
validator.setValidationMessageSource(messageSource());
return validator;
}
}
Pom.xml
xml文件
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>2.0.1.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.2.4.Final</version>
</dependency>
Conclusion:hibernate dependencies required.
结论：需要休眠依赖项。
