lombok @Accessors用法

chain的中文含义是链式的，设置为true，则setter方法返回当前对象。如下

<span style="color: #008080;"> 1</span> <span style="color: #000000;">@Data
</span><span style="color: #008080;"> 2</span> @Accessors(chain = <span style="color: #0000ff;">true</span><span style="color: #000000;">)
</span><span style="color: #008080;"> 3</span> <span style="color: #0000ff;">public</span> <span style="color: #0000ff;">class</span><span style="color: #000000;"> User {
</span><span style="color: #008080;"> 4</span>     <span style="color: #0000ff;">private</span><span style="color: #000000;"> Long id;
</span><span style="color: #008080;"> 5</span>     <span style="color: #0000ff;">private</span><span style="color: #000000;"> String name;
</span><span style="color: #008080;"> 6</span>     
<span style="color: #008080;"> 7</span>     <span style="color: #008000;">//</span><span style="color: #008000;"> 生成的setter方法如下，方法体略</span>
<span style="color: #008080;"> 8</span>     <span style="color: #0000ff;">public</span><span style="color: #000000;"> User setId(Long id) {}
</span><span style="color: #008080;"> 9</span>     <span style="color: #0000ff;">public</span><span style="color: #000000;"> User setName(String name) {}
</span><span style="color: #008080;">10</span> }

prefix

prefix的中文含义是前缀，用于生成getter和setter方法的字段名会忽视指定前缀（遵守驼峰命名）。如下

<span style="color: #008080;"> 1</span> <span style="color: #000000;">@Data
</span><span style="color: #008080;"> 2</span> @Accessors(prefix = "p"<span style="color: #000000;">)
</span><span style="color: #008080;"> 3</span> <span style="color: #0000ff;">class</span><span style="color: #000000;"> User {
</span><span style="color: #008080;"> 4</span>     <span style="color: #0000ff;">private</span><span style="color: #000000;"> Long pId;
</span><span style="color: #008080;"> 5</span>     <span style="color: #0000ff;">private</span><span style="color: #000000;"> String pName;
</span><span style="color: #008080;"> 6</span>     
<span style="color: #008080;"> 7</span>     <span style="color: #008000;">//</span><span style="color: #008000;"> 生成的getter和setter方法如下，方法体略</span>
<span style="color: #008080;"> 8</span>     <span style="color: #0000ff;">public</span><span style="color: #000000;"> Long getId() {}
</span><span style="color: #008080;"> 9</span>     <span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> setId(Long id) {}
</span><span style="color: #008080;">10</span>     <span style="color: #0000ff;">public</span><span style="color: #000000;"> String getName() {}
</span><span style="color: #008080;">11</span>     <span style="color: #0000ff;">public</span> <span style="color: #0000ff;">void</span><span style="color: #000000;"> setName(String name) {}
</span><span style="color: #008080;">12</span> }
