Use jsonassert framework to compare two json are same or not. It only compare the content of them. The example code is here;
public class JsonAssertClient {
public static void main(String[] args) {
String json1Str = "{ \"name\":\"henry\", \"age\":\"28\" }";
String json2Str = "{ \"name\":\"henry2\", \"age\":\"28\" }";
String json3StrWithBlank = "{ \"name\" : \"henry\" , \"age\" : \"28\" }";
String json4StrWithDiffOrder = "{\"age\":\"28\", \"name\":\"henry\"}";
System.out.println("json1 is same with json2:" + isSame(json1Str, json2Str));
System.out.println("json1 is same with json3:" + isSame(json1Str, json3StrWithBlank));
System.out.println("json1 is same with json4:" + isSame(json1Str, json4StrWithDiffOrder));
}
private static boolean isSame(String json1, String json2) {
try {
JSONAssert.assertEquals(json1, json2, true);
} catch (AssertionError e){
return false;
} catch (JSONException e) {
System.out.println("json format error!");
return false;
}
return true;
}
}
output
json1 is same with json2:false
json1 is same with json3:true
json1 is same with json4:true
