How to get specific stub on multiple matching URL with different queryParameter - api

Question

I have 2 WireMock mappings JSON files with same URL. In the first mapping JSON file, I only have a xDate as query parameter. In the 2nd mapping JSON file, I have the xDate and yType as query parameters.
How do I make the stub such that when I hit the URL with the 2 parameters, it will get the correct mapping/file information.
1st mapping json file:
"request" : {
"customMatcher" : {
"name" : "is-today",
"parameters" : {
"queryParamName" : "xDate",
"dateFormat": "yyyy-MM-dd"
}
},
"urlPathPattern" : "/myUrl",
"method" : "GET"
},
"response" : {
"status" : 200,
"bodyFileName" : "body1.json",
"headers" : {
"Server" : "Apache-Coyote/1.1",
"Content-Type" : "application/json"
}
}
2nd mapping json:
"request" : {
"customMatcher" : {
"name" : "is-today",
"parameters" : {
"queryParamName" : "xDate",
"dateFormat": "yyyy-MM-dd"
}
},
"queryParameters":{
"yType" : {
"equalTo": "Value"
}
},
"urlPathPattern" : "/myUrl",
"method" : "GET"
},
"response" : {
"status" : 200,
"bodyFileName" : "body2.json",
"headers" : {
"Server" : "Apache-Coyote/1.1",
"Content-Type" : "application/json"
}
}
When I was testing it, it always hits the 1st mapping JSON. When I tried to hit the URL with 2 input parameters, it always go to the 1st mapping.
Tried putting the "priority" value on 1st and 2nd mapping file but somehow, its not working properly for me.
