启动类加@EnableAsync注解开启异步调用方法功能
在加@Async注解的异步方法里面调用如下代码上传神策数据
public void track(String distinctId,String eventName,Map<String,Object> properties) throws Exception{ final SensorsAnalytics sa = new SensorsAnalytics(new SensorsAnalytics.ConcurrentLoggingConsumer("D:\\myfolder\\sensors\\access.log")); sa.track(distinctId,true,eventName,properties); //程序结束前，停止神策分析SDK所有服务 sa.shutdown(); }
报错信息如下：

源码分析：
在如下代码处抛出异常信息“fail to write file.”
public boolean write(StringBuilder sb) { synchronized(this.lockStream) { FileLock lock = null; try { FileChannel channel = this.lockStream.getChannel(); lock = channel.lock(0L, 9223372036854775807L, false); this.outputStream.write(sb.toString().getBytes("UTF-8")); } catch (Exception var14) { throw new RuntimeException("fail to write file.", var14); } finally { if (lock != null) { try { lock.release(); } catch (IOException var13) { throw new RuntimeException("fail to release file lock.", var13); } } } return true; } }
!this.isOpen()为true，导致var20为null,(FileLock)var20异常，最后走finally代码块结束。
public FileLock lock(long var1, long var3, boolean var5) throws IOException { this.ensureOpen(); if (var5 && !this.readable) { throw new NonReadableChannelException(); } else if (!var5 && !this.writable) { throw new NonWritableChannelException(); } else { FileLockImpl var6 = new FileLockImpl(this, var1, var3, var5); FileLockTable var7 = this.fileLockTable(); var7.add(var6); boolean var8 = false; int var9 = -1; try { this.begin(); var9 = this.threads.add(); if (!this.isOpen()) { Object var20 = null; return (FileLock)var20; } int var10; do { var10 = this.nd.lock(this.fd, true, var1, var3, var5); } while(var10 == 2 && this.isOpen()); if (this.isOpen()) { if (var10 == 1) { assert var5; FileLockImpl var11 = new FileLockImpl(this, var1, var3, false); var7.replace(var6, var11); var6 = var11; } var8 = true; } } finally { if (!var8) { var7.remove(var6); } this.threads.remove(var9); try { this.end(var8); } catch (ClosedByInterruptException var18) { throw new FileLockInterruptionException(); } } return var6; } }
此问题不知是什么原因？？？？？？？
