使用java.lang.Process从php代码读取属性

Question

我正在使用java.lang.Process运行PHP代码，我想从PHP代码返回一个值，所以我可以从Process获取它，我该怎么做？

这是我正在使用的代码：

public void callPhpListener(String handler, String logFile, String messageId) throws Exception {
try {
  LOGGER.info("Calling PHP executore with message id:" + messageId);
  // LOGGER.info("Handler:" + handler + ", logFile:" + logFile + ", message id:" + messageId);
  Process exec = Runtime.getRuntime().exec(
      new String[] {"/bin/bash", "-c",
        "php " + handler + " " + messageId +
          " >> " + logFile + "  2>&1"});
  exec.waitFor();
  int exitValue = exec.exitValue();
  LOGGER.info("exit value is " + exitValue);
  if(exitValue != 0) {
      throw new Exception("Processed with error");
  }
    LOGGER.info("Done processing message with id:" + messageId);
  } catch (Exception e) {
    LOGGER.error(e.getMessage());
    throw new Exception();
  }

}
