根据这个问题的推荐，我试图在我的问题上添加另一个版本的hibernate-validator POM但错误仍然存​​在。

As per recomendation on this issue i have tried to add another version of hibernate-validator on my POM but error persist.

推荐答案

已解决

出于某种原因，人工制造spring-boot-starter -web为hibernate-validator添加了一个依赖项，因此spring期待我配置一个验证器依赖项。

For some reason artefact spring-boot-starter-web added a dependency to hibernate-validator, therefore spring was expecting me to configure a validator dependency.

我删除了依赖项，在我的pom.xml中添加了一个排除项。

I have remove that dependency adding an exclusion to my pom.xml.

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-validator</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

我添加了更多依赖项，包括JPA，它仍然正常工作。

I have added more dependencies including JPA and It is still working fine.
