Spring框架:执行Spring Boot后出现Bean验证Api错误

Question

大家好，我是使用Spring框架的新手，我试着遵循那里网站上的指南

pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<name>Spring Boot Tutorial</name>
<description>A simple tutorial for spring boot</description>

 <!-- Inherit defaults from Spring Boot -->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.7.RELEASE</version>
</parent>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>


<properties>
    <java.version>1.8</java.version>
</properties>

​

我在src/ Application.java /java中创建了如下代码。

Application.java

package Application.com;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

但是当我运行应用程序时，我得到了这个错误

***************************
APPLICATION FAILED TO START
***************************

Description:

The Bean Validation API is on the classpath but no implementation could be found

Action:

Add an implementation, such as Hibernate Validator, to the classpath

我使用的是spring环境工具套件，这里有什么问题吗？谢谢

我删除了.m2/repository，然后使用1.5.7.RELEASE重新构建，然后启动应用程序。我认为从Maven主路径读取jar文件时可能存在一些冗余问题。
