Android studio 插件之 GsonFormat (自动生成javabean)
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.
