href="#状态码"><span>状态码</span></a></h2><p>从 0.10 版本开始 IoTDB 引入了<strong>状态码</strong>这一概念。例如，因为 IoTDB 需要在写入数据之前首先注册时间序列，一种可能的解决方案是：</p><div class="language-text line-numbers-mode" data-ext="text" data-title="text"><pre class="language-text"><code>try {
    writeData();
} catch (SQLException e) {
  // the most case is that the time series does not exist
  if (e.getMessage().contains(&quot;exist&quot;)) {
      //However, using the content of the error message is not so efficient
      registerTimeSeries();
      //write data once again
      writeData();
  }
}

</code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div><div class="line-number"></div><div class="line-number"></div><div class="line-number"></div><div

class="line-number"></div><div class="line-number"></div></div></div><p>利用状态码，我们就可以不必写诸如<code>if (e.getErrorMessage().contains(&quot;exist&quot;))</code>的代码，只需要使用<code>e.getStatusType().getCode() == TSStatusCode.TIME_SERIES_NOT_EXIST_ERROR.getStatusCode()</code>。</p><p>这里是状态码和相对应信息的列表：</p><table><thead><tr><th style="text-align:left;">状态码</th><th style="text-align:left;">状态类型</th><th

的异常类。通过将错误信息统一提取到异常类中，并为所有异常添加不同的错误代码，从而当捕获到异常并引发更高级别的异常时，错误代码将保留并传递，以便用户了解详细的错误原因。<br> 除此之外，我们添加了一个基础异常类“ProcessException”，由所有异常扩展。</p></blockquote></div><!--[--><!----><!--]--><footer
