##序在使用jodconverter进行pdf转换的时候，按默认的配置，请求量一上来就报错"org.jodconverter.office.OfficeException: No office manager available."

##异常

##源码 ###参数 jodconverter-core-4.0.0-RELEASE-sources.jar!/org/jodconverter/office/DefaultOfficeManagerBuilder.java

final int numInstances =        connectionProtocol == OfficeConnectionProtocol.PIPE ? pipeNames.length : portNumbers.length;    final UnoUrl[] unoUrls = new UnoUrl[numInstances];    for (int i = 0; i < numInstances; i++) {      unoUrls[i] =          (connectionProtocol == OfficeConnectionProtocol.PIPE)              ? UnoUrlUtils.pipe(pipeNames[i])              : UnoUrlUtils.socket(portNumbers[i]);    }

###构造器

/** Constructs a new instance of the class with the specified settings. */  public ProcessPoolOfficeManager(      final UnoUrl[] unoUrls,      final File officeHome,      final File workingDir,      final ProcessManager processManager,      final String[] runAsArgs,      final File templateProfileDir,      final long retryTimeout,      final long retryInterval,      final boolean killExistingProcess,      final long taskQueueTimeout,      final long taskExecutionTimeout,      final int maxTasksPerProcess) {    this.taskQueueTimeout = taskQueueTimeout;    pool = new ArrayBlockingQueue<>(unoUrls.length);    pooledManagers = new PooledOfficeManager[unoUrls.length];    for (int i = 0; i < unoUrls.length; i++) {      final PooledOfficeManagerSettings settings =          new PooledOfficeManagerSettings(unoUrls[i], officeHome, workingDir, processManager);      settings.setRunAsArgs(runAsArgs);      settings.setTemplateProfileDir(templateProfileDir);      settings.setRetryTimeout(retryTimeout);      settings.setRetryInterval(retryInterval);      settings.setKillExistingProcess(killExistingProcess);      settings.setTaskExecutionTimeout(taskExecutionTimeout);      settings.setMaxTasksPerProcess(maxTasksPerProcess);      pooledManagers[i] = new PooledOfficeManager(settings);    }    logger.debug(        "ProcessManager implementation is '{}'", processManager.getClass().getSimpleName());  }

##解决

jodconverter:  enabled: true  portNumbers: 2002,2003,2004,2005,2006  maxTasksPerProcess: 1000  taskQueueTimeout: 30

通过设置多个port，可以启动多个office 通过设置maxTasksPerProcess，可以增加队列容量
