Gson解析java嵌套类的属性及其属性值，将java类转成java字符串数组，API接口写属性有用

import com.google.gson.Gson; import com.google.gson.GsonBuilder; Gson gson = new GsonBuilder().serializeNulls().enableComplexMapKeySerialization().disableHtmlEscaping().create(); PictrueConditionVo pictrueConditionVo=new PictrueConditionVo(); List<PictureTemplate> pictureTemplates=new ArrayList<>(); pictureTemplates.add(new PictureTemplate()); pictrueConditionVo.setPictureTemplates(pictureTemplates); Picture label=new Picture(); PictureDivReport pictureDivReport=new PictureDivReport(); pictrueConditionVo.setLabel(label); /**分析标签层级**/ List<PictureDiv> tags = new ArrayList<>(); tags.add(new PictureDiv()); /**分析标签层级条件与tags数量要一致**/ List<ParentLogicalOperatorConditionPictrueVo> conditions=new ArrayList<>(); conditions.add(new ParentLogicalOperatorConditionPictrueVo()); pictrueConditionVo.setConditions(conditions); pictrueConditionVo.setPictureDivReport(pictureDivReport); String json = gson.toJson(pictrueConditionVo); System.out.println(json);

样列数据
