Snack3 3.1.10的新特性及应用

<dependency> <groupId>org.noear</groupId> <artifactId>snack3</artifactId> <version>3.1.10</version> </dependency>

（一）增加特性：Feature.StringJsonToNode

//注意：data 的值是个 string String json = "{id:1,name:'x', data:'{user_id:6}'}"; ONode oNode = ONode.loadStr(json, Feature.StringJsonToNode); int user_id = oNode.get("data").get("user_id").getInt(); //或用Jsonpath: int user_id = oNode.select("data.user_id").getInt(); //assert user_id == 6;

（二）增加接口：ONode::fillObj()，ONode::fillStr()

String json = "{id:1,name:'x', data:{user_id:6,icon:'fa1',type:2}}"; ONode oNode = ONode.loadStr(json); //用新的 Json string 填充 data 的内容 oNode.get("data").fillStr("{user_id:8,mobile:'123'}"); int user_id = oNode.get("data").get("user_id").getInt(); //assert user_id == 8;

（三）增强接口：ONode::set(key, obj)，ONode::val(obj)

List<Object> list = new ArrayList<>(); list.add(1); list.add("a"); Map<String,Object> map = new LinkedHashMap<>(); map.put("k1",1); map.put("k2","a"); ONode oNode = new ONode(); oNode.set("map", map); oNode.set("list",list); oNode.get("list2").val(list);
