spring boot 整合 FastDFS

原文链接： https://blog.csdn.net/ityqing/article/details/81384740

1.引入依赖

    com.github.tobato
    fastdfs-client
    1.26.2

2.引入FastDFS

@SpringBootApplication
@Import(FdfsClientConfig.class)
// 解决jmx重复注册bean的问题
@EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)
public class ApiApplication {

	public static void main(String[] args) {
		SpringApplication.run(ApiApplication.class, args);
	}

对的，只需要一行注解 @Import(FdfsClientConfig.class)就可以拥有带有连接池的FastDFS Java客户端了。

如果不加 spring.jmx.enabled=false 和 @EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING) 启动项目时会报异常: 
 

org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [FdfsConnectionPool [maxTotal=50, blockWhenExhausted=true, maxWaitMillis=100, lifo=true, fairness=false, testOnCreate=false, testOnBorrow=false, testOnReturn=false, testWhileIdle=true, timeBetweenEvictionRunsMillis=60000, numTestsPerEvictionRun=-1, minEvictableIdleTimeMillis=180000, softMinEvictableIdleTimeMillis=-1, evictionPolicy=org.apache.commons.pool2.impl.DefaultEvictionPolicy@1a05ff8e, closeLock=java.lang.Object@251e2f4a, closed=false, evictionLock=java.lang.Object@1abea1ed, evictor=org.apache.commons.pool2.impl.BaseGenericObjectPool$Evictor@6f5288c5, evictionIterator=null, factoryClassLoader=java.lang.ref.WeakReference@5a9ef32e, oname=org.apache.commons.pool2:type=GenericKeyedObjectPool,name=pool, creationStackTrace=java.lang.Exception

推荐使用 : @EnableMBeanExport(registration = RegistrationPolicy.IGNORE_EXISTING)

 

3.在application.yml当中配置Fdfs相关参数

# ===================================================================
# 分布式文件系统FDFS配置
# ===================================================================
fdfs:
  so-timeout: 1501
  connect-timeout: 601 
  thumb-image:             #缩略图生成参数
    width: 150
    height: 150
  tracker-list:            #TrackerList参数,支持多个
    - 192.168.1.105:22122
    - 192.168.1.106:22122
