在可执行 java命令的情况下查找过程如下:</p>
<p>
执行which java</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_653716">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain"></code><code class="bash comments"># which java</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">/usr/bin/java</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
执行ls -lrt /usr/bin/java</p>
<div class="jb51code">

<div class="syntaxhighlighterjava" id="highlighter_499005">
<div class="toolbar">

由上可知java的路径为: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.144-0.b01.el7_4.x86_64,进入该路径查看文件如下:</p>
<div class="jb51code">
