<summary type="html">&lt;p&gt;springboot 自动装配调用链&lt;/p&gt;
&lt;p&gt;springboot 相比 spring能更方便开发人员上手，比较重要的一点就是自动装配，大致来看下这个逻辑&lt;/p&gt;
&lt;pre class=&quot;line-numbers language-java&quot; data-language=&quot;java&quot;&gt;&lt;code class=&quot;language-java&quot;&gt;&lt;span class=&quot;token keyword&quot;&gt;public&lt;/span&gt; &lt;span class=&quot;token keyword&quot;&gt;static&lt;/span&gt; &lt;span class=&quot;token keyword&quot;&gt;void&lt;/span&gt; &lt;span class=&quot;token function&quot;&gt;main&lt;/span&gt;&lt;span class=&quot;token punctuation&quot;&gt;(&lt;/span&gt;&lt;span class=&quot;token class-name&quot;&gt;String&lt;/span&gt;&lt;span class=&quot;token punctuation&quot;&gt;[&lt;/span&gt;&lt;span class=&quot;token punctuation&quot;&gt;]&lt;/span&gt; args&lt;span class=&quot;token punctuation&quot;&gt;)&lt;/span&gt; &lt;span class=&quot;token punctuation&quot;&gt;&amp;#123;&lt;/span&gt;

&lt;span class=&quot;token punctuation&quot;&gt;&amp;#125;&lt;/span&gt;
&lt;span class=&quot;token comment&quot;&gt;/**
