概述

相信大家在做开发的过程中都写过很多的javabean ,很多情况下都是一个列表数据就是一个单独的javabean，如果大家自己敲的话费时费力还很容易敲错。

今天给大家推荐一个插件 GsonFormat ?这个插件就是可以让我们直接将服务端返回的json转化为实体类，Android studio和idea都有， eclipse我没有试过。大家可以找找有没有。

操作步骤

第一步 ?下载插件

下载插件的过程我前面有一篇博客已经有详细步骤??Android Studio插件之sexy editor（设置AS背景）?大家只需要将那篇博客中介绍的插件名称换成GsonFormat

按照那个步骤下载好插件。记得下载安装好后要重启哦。

第二步 ?自动生成bean

下面我们介绍怎么通过这个插件将服务端返回的json自动生成javabean

首先 ?我们要建一个空的java类，然后在空白出点击鼠标右键 ?选择 Generate... 如果你已经成功安装好插件会弹出下面这个框

选择GsonFormat会弹出下面这个框

将服务端接返回的json 粘贴到这个里面点击ok

?粘贴完成后点击ok会弹出如下图所示的选择字段界面

这个界面是让你自己选择保留哪些字段，可能有的字段不需要就把前面的对勾去掉就可以了。最后点击ok，大功告成。

贴上json字符串和自动生成出的bean代码.
