JSONObject将json字符串转成java嵌套对象

java测试嵌套对象的转换

String jsonData="{"id":null,"createUser":10017,"createTime":"2022-08-16T09:18:08.000+08:00","updateUser":10017,"updateTime":"2022-08-16T09:18:18.000+08:00","tenantId":0,"dataVersion":null,"dataState":"1","optContext":null,"flag":1,"pageModel":null,"pageMap":null,"permissionDeptId":10001,"permissionDeptIdList":null,"hasPermission":true,"filterPermission":true,"indexStdId":2000,"indexName":"测试指标","enName":"ssss","indexExpression":"jjj","indexStatus":3,"remark":null,"indexStdFieldList":[{"id":null,"createUser":10017,"createTime":"2022-08-16T09:18:08.000+08:00","updateUser":10017,"updateTime":"2022-08-16T09:18:08.000+08:00","tenantId":0,"dataVersion":null,"dataState":"1","optContext":null,"flag":1,"pageModel":null,"pageMap":null,"permissionDeptId":10001,"permissionDeptIdList":null,"hasPermission":true,"filterPermission":true,"indexStdFieldId":82,"indexStdId":2000,"fieldName":"kkk","cnName":"kkk","fieldDesc":"kkk","orderNum":1,"remark":null,"newRecord":true,"valid":true}],"relatedDimensionId":null,"createUserName":null,"relatedDimensionCount":null,"newRecord":true,"valid":true}";
JSONObject jsonObject = JSONObject.parseObject(jsonData);
转json数组

IndexStd indexStd = JSONObject.toJavaObject(jsonObject, IndexStd.class);
转java对象

System.out.println(indexStd.getIndexName());
