IntelliJ IDEA开发工具插件GsonFormat插件安装使用

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 {


    /**
     * acIdttbPressFilterConfEntities : []

可以看到确实将id替换成了newId，这个插件在一些特定场合还是比较实用的，大家觉得如何呢
