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());
