</table><p>这里重点要说明的是观察表达式，观察表达式的构成主要由 ognl 表达式组成，所以你可以这样写<code class="docutils literal notranslate"><span class="pre">"{params,returnObj}"</span></code>，只要是一个合法的 ognl 表达式，都能被正常支持。</p>
|
|
|
<p>观察的维度也比较多，主要体现在参数 <code class="docutils literal notranslate"><span class="pre">advice</span></code> 的数据结构上。<code class="docutils literal notranslate"><span class="pre">Advice</span></code> 参数最主要是封装了通知节点的所有信息。请参考<a class="reference internal" href="advice-class.html"><span class="doc">表达式核心变量</span></a>中关于该节点的描述。</p>

<p><strong>特别说明</strong>：</p>
|

<ul class="simple">

<li>watch 命令定义了4个观察事件点，即 <code class="docutils literal notranslate"><span class="pre">-b</span></code> 方法调用前，<code class="docutils literal notranslate"><span class="pre">-e</span></code> 方法异常后，<code class="docutils literal notranslate"><span class="pre">-s</span></code> 方法返回后，<code class="docutils literal notranslate"><span class="pre">-f</span></code> 方法结束后</li>
|
|
|
<li>4个观察事件点 <code class="docutils literal notranslate"><span class="pre">-b</span></code>、<code class="docutils literal notranslate"><span class="pre">-e</span></code>、<code class="docutils literal notranslate"><span class="pre">-s</span></code> 默认关闭，<code class="docutils literal notranslate"><span class="pre">-f</span></code> 默认打开，当指定观察点被打开后，在相应事件点会对观察表达式进行求值并输出</li>
|
|
|
<li>这里要注意<code class="docutils literal notranslate"><span class="pre">方法入参</span></code>和<code class="docutils literal notranslate"><span class="pre">方法出参</span></code>的区别，有可能在中间被修改导致前后不一致，除了 <code class="docutils literal notranslate"><span class="pre">-b</span></code> 事件点 <code class="docutils literal notranslate"><span class="pre">params</span></code> 代表方法入参外，其余事件都代表方法出参</li>
|
|
|
<li>当使用 <code class="docutils literal notranslate"><span class="pre">-b</span></code> 时，由于观察事件点是在方法调用前，此时返回值或异常均不存在</li>
