  • 将json转换为数据结构体

    主要用到的依赖:(划重点:这个依赖需要加jdk版本号,不加的话用不了,且目前最高是jdk15)

    (ps: 用于json与其他类型格式转换,JSONObject, JSONArray等来自这个包)

        <!-- https://mvnrepository.com/artifact/net.sf.json-lib/json-lib -->
        <dependency>
            <groupId>net.sf.json-lib</groupId>
            <artifactId>json-lib</artifactId>
            <version>2.4</version>
            <classifier>jdk15</classifier>
        </dependency>

    核心代码:

    package cn.ucmed.pangu.lib;
    
    import net.sf.json.JSONArray;
    import net.sf.json.JSONObject;
    import org.apache.commons.collections.CollectionUtils;
    
    import java.util.ArrayList;
    import java.util.Iterator;
    import java.util.List;
    
    public class ConvertTool {
    
        public static List<BaseNode> analysisRequestJson(Object json) {
            List<BaseNode> baseNodeList = new ArrayList<>();
            NodeContainer nodeContainer = new NodeContainer(null, null, null, null);
            if (json instanceof JSONArray) {
                JSONArray jsonArray = (JSONArray) json;
                jsonArray.forEach(j -> analysisRequestJson(j));
            } else if (json instanceof JSONObject) {
                JSONObject jsonObject = (JSONObject) json;
                Iterator iterator = jsonObject.keys();
                while (iterator.hasNext()) {
                    String key = iterator.next().toString();
                    Object o = ((JSONObject) json).get(key);
                    if (o instanceof JSONArray) {
                        JSONArray jsonArray = (JSONArray) o;
                        analysisRequestJson(jsonArray);
                    } else if (o instanceof JSONObject) {
                        List<BaseNode> list = analysisRequestJson((JSONObject) o);
                        nodeContainer = new NodeContainer(key, null, list);
                    } else {
                        baseNodeList.add(new NodeLeafConstant(key, o.toString(), o.getClass().getTypeName().replace("java.lang.", "")));
                    }
                }
                if (CollectionUtils.isNotEmpty(nodeContainer.nodeList)) {
                    baseNodeList.add(nodeContainer);
                }
            }
            return baseNodeList;
        }
    }
