概述

相信大家在做开发的过程中都写过非常多的javabean ,非常多情况下 都是一个列表数据就是一个单独的javabean。假设大家自己敲的话费时费力 还非常easy敲错。

今天给大家推荐一个插件 GsonFormat  这个插件就是能够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。

大家能够找找有没有。

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具体步骤 Android Studio插件之sexy editor（设置AS背景） 大家 仅仅须要将那篇博客中介绍的插件名称换成GsonFormat

依照那个步骤下载好 插件。记得下载安装好后要重新启动哦。

第二步  自己主动生成bean

以下我们介绍怎么通过这个插件将服务端返回的json自己主动生成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... 假设你已经安装成功好插件会弹出以下这个框

选择GsonFormat会弹出以下这个框

将服务端接返回的json 粘贴到这个里面 点击ok

粘贴完毕后 点击ok会弹出例如以下图所看到的的选择 字段界面

这个界面是让你自己选择 保留哪些字段。可能有的字段不须要 就把前面的对勾去掉就能够了。最后点击ok。大功告成。

贴上json字符串和自己主动生成出的bean代码.
