sentinel是阿里巴巴的服务保护框架，可以限流、熔断等。
但是我在系统中引入sentinel包后系统就报错：

2022-07-27 17:17:05.410  WARN 20124 --- [           main] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.alibaba.cloud.sentinel.custom.SentinelAutoConfiguration': Unsatisfied dependency expressed through field 'properties'; nested exception is org.springframework.boot.context.properties.ConfigurationPropertiesBindException: Error creating bean with name 'spring.cloud.sentinel-com.alibaba.cloud.sentinel.SentinelProperties': Could not bind properties to 'SentinelProperties' : prefix=spring.cloud.sentinel, ignoreInvalidFields=false, ignoreUnknownFields=true; nested exception is javax.validation.NoProviderFoundException: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

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

我用了一天的时间参找到错误。
因为我的系统中使用swagger规范文档插件，以及knife4j界面加强工具。
其中knife4j架包与sentinel冲突

<!--    knife4j 接口文档界面显示加强    -->
        <dependency>
            <groupId>com.github.xiaoymin</groupId>
            <artifactId>knife4j-spring-boot-starter</artifactId>
            <version>${knife4j.version}</version>
            <!-- 去除validation-api -->
            <exclusions>
                <exclusion>
                    <groupId>javax.validation</groupId>
                    <artifactId>validation-api</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

之后就可以了
