How to quickly build Java Bean objects from JSON

When docking with a third party, the JSON time parameter fields that are returned to us are very common, so it's certainly going to take a while for us to create javabean manually, so we can use JSON to automatically generate JavaBean tools, here's a brief introduction to IntelliJ idea Plug-in Gsonformat in the.

1. What is Gsonformat

Converts the JSON data format into a Java Bean object's as plug-in.

2. Shortcut key ctrl+alt+s, or settings-->plugins-and input Gsonformat install Plugins

After installation, restart IntelliJ idea.

Now generate a corresponding bean from the following JSON string.

{    "Success":true,    "msg":"Success",    "ErrorCode":20000,    "Data":{        "Roomid":123,        "isnew":true    }}

First you need a new class file (first to create an empty class, nothing),

Copy the JSON you want to parse.

Then Alt+insert pops up the following screen

Formatting JSON

can set

Generated as follows:

 Public classResponsevo {/*** success:true * msg: Success * errorcode:20000 * data: {"Roomid": 123, "IsNew": true}*/    Private Booleansuccess; PrivateString msg; Private intErrorCode; PrivateDatabean data;  Public Booleanissuccess () {returnsuccess; }     Public voidSetsuccess (Booleansuccess) {         This. Success =success; }     PublicString getmsg () {returnmsg; }     Public voidsetmsg (String msg) { This. msg =msg; }     Public intGetErrorCode () {returnErrorCode; }     Public voidSeterrorcode (intErrorCode) {         This. ErrorCode =ErrorCode; }     PublicDatabean GetData () {returndata; }     Public voidsetData (Databean data) { This. data =data; }     Public Static classDatabean {/*** roomid:123 * isnew:true*/        Private intRoomid; Private Booleanisnew;  Public intGetroomid () {returnRoomid; }         Public voidSetroomid (intRoomid) {             This. Roomid =Roomid; }         Public Booleanisisnew () {returnisnew; }         Public voidSetisnew (Booleanisnew) {             This. isnew =isnew; }    }}
