Question

When starting the springboot service, the service reports an error. The specific error information is as follows:

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

reason:

Dependency in POM

<dependency>
            <groupId>org.hibernate.validator</groupId>
            <artifactId>hibernate-validator</artifactId>
            <version>7.0.0.Final</version>
        </dependency>

And

<dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
            <version>2.2.6.RELEASE</version>
        </dependency>

Conflict.

Solution:

The dependency is deleted because it is not used in the service

<dependency>
            <groupId>org.hibernate.validator</groupId>
            <artifactId>hibernate-validator</artifactId>
            <version>7.0.0.Final</version>
        </dependency>

Restart the service normally.
