今天给大家介绍一款很实用的GsonFormat插件，GsonFormat插件能够将我们的json格式数据生成对应的实体类，层级关系通过内部类来嵌套，这个工具有时候是很实用的，例如以前公司在对接第三方接口的时候，他们通常提供的入参形式是json形式，但是对于java来说，我们为了方便赋值和接收三方的值，要将其转成对象，所以这个时候我们就需要创建一个对象，但是如果json参数比较多，很容易出错，这个工具就用到了，完美解决我们的机械操作问题。下面来介绍如何安装以及如何使用。
安装插件
和安装其他插件方式相同，Mac在Preferences ->》plugins
输入GsonFormat，如下图所示，点击Install
?下载后点击OK，会提示重启，点击重新启动则可。
使用方式
?先构造一个正确JSON格式数据，如下
{
?? ?"acIdttbPressFilterConfEntities": [],
?? ?"acIdttbPressNodeConfEntityList": [{
?? ??? ?"acComTransRuleDefnEntity": {
?? ??? ??? ?"acComTransRuleDetailEntityList": [{
?? ??? ??? ??? ?"detailSort": 1,
?? ??? ??? ??? ?"effectiveTime": -9223372036854776000,
?? ??? ??? ??? ?"exeConditionExps": "",
?? ??? ??? ??? ?"expirationTime": 9223372036854776000,
?? ??? ??? ??? ?"ruleDefnId": 529,
?? ??? ??? ??? ?"targetPath": ""
?? ??? ??? ?}, {
?? ??? ??? ??? ?"detailSort": 2,
?? ??? ??? ??? ?"effectiveTime": -9223372036854776000,
?? ??? ??? ??? ?"exeConditionExps": "",
?? ??? ??? ??? ?"expirationTime": 9223372036854776000,
?? ??? ??? ??? ?"ruleDefnId": 529,
?? ??? ??? ??? ?"targetPath": "",
?? ??? ??? ??? ?"targetValueExps": ""
?? ??? ??? ?}],
?? ??? ??? ?"effectiveTime": -9223372036854776000,
?? ??? ??? ?"expirationTime": 9223372036854776000,
?? ??? ??? ?"id": 529
?? ??? ?},
?? ??? ?"comTransRuleDefnId": 529,
?? ??? ?"effectiveTime": -9223372036854776000,
?? ??? ?"expirationTime": 9223372036854776000,
?? ??? ?"id": 1240,
?? ??? ?"nodeType": "common_transfer_rule",
?? ??? ?"pressId": 361,
?? ??? ?"stdBillOper": "",
?? ??? ?"stdBillType": ""
?? ?}],
?? ?"id": 361,
?? ?"pressColId": 0,
?? ?"pressToNormalFunctionBean": "",
?? ?"runInStyles": 2,
?? ?"taskId": 0
}?
新建一个类：CurrentRecognised，该插件有快捷键，Mac是option + s 即可弹出下面框，但是如果你本身工具已经存在该快捷键，那么可以该快捷键会失效，这种情况下，要通过在该类中，右键，在弹出的对话框中选择Generate，选择点击后会弹出GET、SET等，我们选择GsonFormat，如下图
?
?Format
将我们提前准备好的JSON数据，复制到框中，在对话框的右上角，还可以进行格式化
?Setting
?在右下角有个Setting按钮，点开后，弹出如下对话框
默认情况下Convert Library 选项是Other ，生成的对象是get set形式，我们可以选择其他选项，例如Lombok，那么会将生成的对象带有Lombok的形式，代码看起来比较整洁，其他选项大家自己体验吧，功能还是有一些的。点击Ok后
我们能修改字段类型、映射后的字段名称，例如我们将 第一个字段id 修改成newId，点击OK后，生成的代码如下
@NoArgsConstructor
@Data
public class CurrentRecognised {
/**
