org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [SftpPool [maxTotal=8, blockWhenExhausted=true, maxWaitMillis=-1, lifo=true, fairness=false, testOnCreate=false, testOnBorrow=false, testOnReturn=false, testWhileIdle=false, timeBetweenEvictionRunsMillis=-1, numTestsPerEvictionRun=3, minEvictableIdleTimeMillis=1800000, softMinEvictableIdleTimeMillis=-1, evictionPolicy=org.apache.commons.pool2.impl.DefaultEvictionPolicy@131c0b6f, closeLock=java.lang.Object@7f030c72, closed=false, evictionLock=java.lang.Object@68d8ae27, evictor=null, evictionIterator=null, factoryClassLoader=java.lang.ref.WeakReference@18513c23, oname=org.apache.commons.pool2:type=GenericObjectPool,name=pool, creationStackTrace=java.lang.Exception

SftConfig 修改如下：

@Configuration
@EnableConfigurationProperties(SftpProperties.class)
public class SftpConfig {
    // 工厂
    @Bean
    public SftpFactory sftpFactory(SftpProperties properties) {
        return new SftpFactory(properties);
    }

    // 连接池
    @Bean
    public SftpPool sftpPool(SftpFactory sftpFactory) {
        GenericObjectPoolConfig poolConfig = sftpFactory.getProperties().getPool();
        poolConfig.setJmxEnabled(false);
        return new SftpPool(sftpFactory);
    }

    // 辅助类
    @Bean
    public SftpUtil sftpUtil(SftpPool sftpPool) {
        return new SftpUtil(sftpPool);
    }
}
