本工具主要是对两个JsonSchema字符串进行比较，入参是两个jsonshema的字符串，一定是jsonschema而不是对象的json字符串，具体可以看例子
工具类代码如下： `public class JsonSchemaUtil {
/**
* @Author
* @Description 比较target与origin的不同
* @Date 上午11:31 2022/2/21
* @Param [origin, target]
* @return void
**/
public static JsonCompareResult compare(String origin,String target){

StringBuilder defect = new StringBuilder();
StringBuilder change = new StringBuilder();
// 多出来
StringBuilder extra = new StringBuilder();
JSONObject originObj = JSONObject.parseObject(origin);
JSONObject targetObj = JSONObject.parseObject(target);
// 解析原始json
JSONObject jsonObject = originObj.getJSONObject("properties");
// 解析对比json
JSONObject targetJsonObject = targetObj.getJSONObject("properties");
if(targetJsonObject == null && jsonObject != null){
change.append("对象数据类型改变，新版本为空");
}else if(targetJsonObject != null && jsonObject == null){
change.append("对象数据类型改变，原版本为空");
}else {
for (Map.Entry entry : jsonObject.entrySet()) {
String key = (String) entry.getKey();
JSONObject valueObject = JSONObject.parseObject(entry.getValue().toString());
String type = valueObject.getString("type");
if (targetJsonObject.get(key) == null) {

continue;
}

if (!type.equals(targetType)) {
change.append("参数key=").append(key).append("类型发生变化，从").append(type).append("改变为")
.append(targetType).append(";");
}
// 如果都是对象
else if ("object".equals(type)) {
JsonCompareResult compare = compare(valueObject.toJSONString(), targetObject.toJSONString());
merge(defect,change,extra,compare,key);
}
// 如果都是数组

private String extra;
public String getDefect() {
return defect;
}
public void setDefect(String defect) {
this.defect = defect;

public void setChange(String change) {
this.change = change;
}
public String getExtra() {
