Spring boot SpringBoot:System.loadLibrary运行两次

我有Spring Boot应用程序版本1.5.3.发布

在主类中，我调用System.loadLibrary：

@SpringBootApplication
@EnableScheduling
public class BlaApplication {

  static {
      System.out.println("xxxxxxxxxxxxxxxxxx Loading Lib");
      System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
  }

  public static void main(String[] args) {

    SpringApplication.run(BlaApplication.class, args);
  }
}

当应用程序启动时，System.loadLibrary被调用两次：

xxxxxxxxxxxxxxxxxx Loading Lib

11:10:51.771 [main] DEBUG org.springframework.boot.devtools.settings.DevToolsSettings - Excluded patterns for restart : [/spring-boot-starter/target/classes/, /spring-boot-autoconfigure/target/classes/, /spring-boot-starter-[\w-]+/, /spring-boot/target/classes/, /spring-boot-actuator/target/classes/, /spring-boot-devtools/target/classes/]

为什么要调用两次？

解决方案是将System.loadLibrary（Core.NATIVE\u LIBRARY\u NAME）在其自己的配置类中：

@Configuration
public class LibLoading {
    static {
       System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    }
}

Java异常处理–未满足LinkError

static {

     try {
            // Attempt to load library.
            System.loadLibrary("XXXXXX"); 
        } catch (UnsatisfiedLinkError error) {
            // Output expected UnsatisfiedLinkErrors.
        } catch (Error | Exception error) {
            // Output unexpected Errors and Exceptions.
        }
}

可能还有另一个类在运行时加载库。如果删除此加载，库是否已加载？但问题是，此特定静态块会运行两次-如果我将logger置于System.loadLibrary（…）之上，我会在控制台中获得2个日志如果删除System.loadLibrary（…），lib根本没有加载到app中，任何对OpenCV的调用都会失败，我猜这是因为为

BlaApplication

创建了类代理。导致两个不同的类具有相同的静态块，因此被初始化两次。如何避免这种情况？
