class="header-anchor" href="#分析问题原因" aria-hidden="true">#</a> 分析问题原因</h3><p>查询静态变量的需求通常来源于需要监控或调试应用程序中某些全局状态的变化。静态变量由于其生命周期与类相同,常用于保存程序运行过程中的共享信息,因此了解其值对于诊断问题是很有帮助的。</p><h3 id="具体步骤" tabindex="-1"><a class="header-anchor" href="#具体步骤" aria-hidden="true">#</a> 具体步骤</h3><h4 id="使用-ognl-命令" tabindex="-1"><a class="header-anchor" href="#使用-ognl-命令" aria-hidden="true">#</a> 使用 <code>ognl</code> 命令</h4><ol><li><p><strong>查看静态变量</strong>:首先,你需要知道想要查询的静态变量所在的全限定类名及变量名。然后,使用 <code>ognl</code> 命令可以直接获取静态变量的值。例如,如果想查看 <code>com.example.MyClass</code> 中名为 <code>myStaticVar</code> 的静态变量,命令如下:</p><div class="language-text ext-text line-numbers-mode"><pre class="language-text"><code>ognl &#39;@com.example.MyClass@myStaticVar&#39;
</code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div></div></div><p>这个命令会打印出该静态变量的当前值。</p></li></ol><h4 id="使用-watch-命令-可选-适用于动态监控" tabindex="-1"><a class="header-anchor" href="#使用-watch-命令-可选-适用于动态监控" aria-hidden="true">#</a> 使用 <code>watch</code> 命令(可选,适用于动态监控)</h4><ol start="2"><li><p><strong>动态跟踪变化</strong>:如果你想在每次该静态变量被修改时都得到通知,可以使用 <code>watch</code> 命令。这不仅会显示当前值,还会在值发生改变时触发并打印相关信息。命令格式如下:</p><div class="language-text ext-text line-numbers-mode"><pre class="language-text"><code>watch com.example.MyClass myStaticVar &quot;{params,returnObj,throwExp -&gt; printf(&#39;myStaticVar updated to: %s\\n&#39;, returnObj)}&quot;
</code></pre><div class="line-numbers" aria-hidden="true"><div class="line-number"></div></div></div><p>这个命令会在 <code>myStaticVar</code> 变化时执行指定的脚本,这里简单地打印出更新后的值。</p></li></ol><h3 id="解释" tabindex="-1"><a class="header-anchor" href="#解释" aria-hidden="true">#</a> 解释</h3><ul><li><code>ognl</code> 命令允许你直接访问和操作Java对象包括静态变量。通过表达式 <code>@类名@变量名</code>,你可以直接读取静态变量的值。</li><li><code>watch</code> 命令则更进一步,它能在每次方法调用前后或变量更改时执行一段脚本,非常适合于动态监控变量的变化情况,为调试提供了强大的灵活性。</li></ul><p>请注意这些操作都需要你的应用正在运行并且已经通过Arthas成功attach到了目标Java进程中。</p><h3 id="结论" tabindex="-1"><a class="header-anchor" href="#结论" aria-hidden="true">#</a> 结论</h3><p>尽管提供的知识内容没有直接包含查询静态变量的方法但基于Arthas的功能我们可以通过上述步骤有效地查询和监控Java应用中的静态变量。如果你有更具体的问题或上述步骤未能解决你的问题请提供更多信息或描述更具体的情景。</p><!----><h2 id="参考链接" tabindex="-1"><a class="header-anchor" href="#参考链接" aria-hidden="true">#</a> 参考链接 </h2><p>*专家经验利用Arthas排查NoSuchMethodError</p><p>*专家经验Arthas 快速启动</p><p>*专家经验arthas 你好</p><!----><h2 id="答疑服务说明" tabindex="-1"><a class="header-anchor" href="#答疑服务说明" aria-hidden="true">#</a> <!----></h2><p>本内容经由技术专家审阅的用户问答的镜像生成,我们提供了<!---->,在<!---->。您也可以访问 : <a href="https://answer.opensource.alibaba.com/docs/intro" target="_blank" rel="noopener noreferrer">全局专家答疑<span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewbox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">在新窗口打开</span></span></a> 。 咨询其他产品的的问题</p><h3 id="反馈" tabindex="-1"><a class="header-anchor" href="#反馈" aria-hidden="true">#</a> 反馈</h3><p>如问答有错漏,欢迎点:<a href="https://ai.nacos.io/user/feedbackByEnhancerGradePOJOID?enhancerGradePOJOId=16087" target="_blank" rel="noopener noreferrer">差评<span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewbox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">在新窗口打开</span></span></a>给我们反馈。</p></div><!--[--><!--]--></div><footer class="page-meta right-menu-padding" data-v-fdd717e0><div class="meta-item edit-link"><a class="external-link meta-item-label" href="https://github.com/alibaba/arthas/edit/master/site/docs/doc/expert/user-question-history15726.md" rel="noopener noreferrer" target="_blank" aria-label="在 GitHub 上编辑此页"><!--[--><!--]--><span>在 GitHub 上编辑此页</span><span><svg class="external-link-icon" xmlns="http://www.w3.org/2000/svg" aria-hidden="true" focusable="false" x="0px" y="0px" viewbox="0 0 100 100" width="15" height="15"><path fill="currentColor" d="M18.8,85.1h56l0,0c2.2,0,4-1.8,4-4v-32h-8v28h-48v-48h28v-8h-32l0,0c-2.2,0-4,1.8-4,4v56C14.8,83.3,16.6,85.1,18.8,85.1z"></path><polygon fill="currentColor" points="45.7,48.7 51.3,54.3 77.2,28.5 77.2,37.2 85.2,37.2 85.2,14.9 62.8,14.9 62.8,22.9 71.5,22.9"></polygon></svg><span class="external-link-icon-sr-only">在新窗口打开</span></span><!--[--><!--]--></a></div><div class="meta-item last-updated"><span class="meta-item-label">Last Updated: </span><!----></div><div class="meta-item contributors"><span class="meta-item-label">贡献者: </span><span class="meta-item-info"><!--[--><!--[--><span class="contributor" title="email: answeropensource@alibabacloud.com">answeropensource</span><!--[-->, <!--]--><!--]--><!--[--><span class="contributor" title="email: hengyunabc@users.noreply.github.com">hengyunabc</span><!----><!--]--><!--]--></span></div></footer><nav class="page-nav right-menu-padding" data-v-fdd717e0><p class="inner"><span class="prev"><a href="/doc/expert/user-question-history13522.html" class="" aria-label="Connect to telnet server error: 127.0.0.1 3658"><!--[--><!--]--> Connect to telnet server error: 127.0.0.1 3658 <!--[--><!--]--></a></span><span class="next"><a href="/doc/expert/user-question-history15740.html" class="" aria-label="arthas 分析内存身高的方法"><!--[--><!--]--> arthas 分析内存身高的方法 <!--[--><!--]--></a></span></p></nav><!--[--><!--]--></main><!--]--></div><!----><!--]--></div>
