解决jdk升级17、21后，fastdfs报because "this.trackerLocator" is null错误

将fastdfs依赖修改为如下即可：

<dependency>
     <groupId>com.github.tobato</groupId>
     <artifactId>fastdfs-client</artifactId>
     <version>1.27.2</version>
     <exclusions>
         <exclusion>
               <groupId>org.slf4j</groupId>
               <artifactId>slf4j-api</artifactId>
         </exclusion>
         <exclusion>
               <groupId>org.slf4j</groupId>
               <artifactId>jcl-over-slf4j</artifactId>
          </exclusion>
          <exclusion>
              <groupId>ch.qos.logback</groupId>
              <artifactId>logback-classic</artifactId>
          </exclusion>
          <exclusion>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-logging</artifactId>
          </exclusion>
    </exclusions>
</dependency>
<dependency>
   <groupId>javax.annotation</groupId>
