[英]Compare two json which has same nested structure and same keys but values can be different?
For example :例如 :
Json A =>
{
"customer": {
"age": 29,
"fullName": "Emily Jenkins",
"year":1988,
"address":{
"lineOne":"lineOne",
"lineTwo":"lineTwo"
}
},
"handset":{
"phone":"0123456789",
"colour":"black"
}
}
Json B =>
{
"customer": {
"fullName": "Sammy J",
"age": 31,
"year":1985,
"address":{
"lineTwo":"lineTwo",
"lineOne":"lineOne"
}
},
"handset":{
"colour":"red",
"phone":"0123456788"
}
}
I want compare these two json and it should return true as keys are matching and both json structure is same.我想比较这两个 json,它应该返回 true,因为键匹配并且两个 json 结构相同。 So is there a clean way of doing it?
那么有没有一种干净的方法呢?
I know using Gson lib I can compare two JsonElement but that would match values as well which I don't want to keep as constraint for my use-case.我知道使用 Gson lib 我可以比较两个 JsonElement 但这也会匹配我不想保留作为我的用例的约束的值。
JsonParser parser = new JsonParser();
JsonElement p1 = parser.parse(JsonA);
JsonElement p2 = parser.parse(JsonB);
System.out.printf(p1.equals(p2) ? "Equal" : "Not Equal"); //it returns true if values are same.
This is indeed a case for JSON Schema validation, refer Core and Validation .这确实是 JSON Schema 验证的情况,请参阅Core和Validation 。
There are a few JSON schema validators available, for the below examples, I am using enter link description here .有一些 JSON 模式验证器可用,对于下面的示例,我在此处使用输入链接描述。 The library binaries are available in Maven, it can also be downloaded (along with all dependency and javadoc) from here .
库二进制文件在 Maven 中可用,也可以从这里下载(以及所有依赖项和 javadoc)。 Other validators are also available from here .
其他验证器也可以从这里获得。
It would perhaps be of help to go throughthis guide .阅读本指南可能会有所帮助。
The schema for the example is as below (SampleJsonSchema.json):该示例的架构如下(SampleJsonSchema.json):
{
"$schema":"http://json-schema.org/draft-07/schema#",
"id":"http://test.org/sampleJsonSchema1",
"title":"SampleJSONSchema",
"description":"This is the description",
"type":"object",
"properties":{
"customer":{
"type":"object",
"properties":{
"fullname":{"type":"string"},
"age":{"type":"integer"},
"year":{"type":"integer"},
"address":{
"type":"object",
"properties":{
"lineOne":{"type":"string"},
"lineTwo":{"type":"string"}
},
"required":["lineOne", "lineTwo"],
"maxProperties":2
}
},
"required":["fullname","age","year","address"],
"maxProperties":4
},
"handset":{
"type":"object",
"properties":{
"phone":{"type":"string"},
"colour":{"type":"string"}
},
"required":["phone","colour"],
"maxProperties":2
}
}
}
The data used is as below (SampleJsonData.json:使用的数据如下(SampleJsonData.json:
{
"customer": {
"fullname": "Emily Jenkins",
"age": 29,
"year":1988,
"address":{
"lineOne":"lineOne",
"lineTwo":"lineTwo"
}
},
"handset":{
"phone":"0123456789",
"colour":"black"
}
}
The validation routine is as below:验证程序如下:
package org.test;包 org.test;
import java.io.File;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.github.fge.jsonschema.core.report.ProcessingReport;
import com.github.fge.jsonschema.main.JsonSchema;
import com.github.fge.jsonschema.main.JsonSchemaFactory;
public class JsonValidation {
public static void main(String[] args) throws Exception{
String jsonSchemaPath="F:\\workspaces\\utilities\\TestJava\\jsonSchema\\SampleJsonSchema.json";
String jsonDataPath="F:\\workspaces\\utilities\\TestJava\\jsonSchema\\SampleJsonData.json";
ObjectMapper mapper=new ObjectMapper();
JsonNode schemaNode=mapper.readValue(new File(jsonSchemaPath), JsonNode.class);
JsonNode dataNode=mapper.readValue(new File(jsonDataPath), JsonNode.class);
JsonSchema jsonSchema=JsonSchemaFactory.byDefault().getJsonSchema(schemaNode);
ProcessingReport validationReport=jsonSchema.validate(dataNode);
System.out.println(validationReport.toString());
}//main closing
}//class closing
A number of tests can be run by changing the schema and the data to observe different results.可以通过更改架构和数据来运行许多测试以观察不同的结果。
