如何验证包含多个有效json请求的requestbody？

Question

When I supply multiple json request under request body for POST request, very first request gets accepted while rest of gets ignored.

I don't want to send list as request infact I am supplying multiple requests or say duplicate request in requestbody.

Here is an example:

Request:

{
  "Business": {
    "name": "ABC"
  }
}
{
  "Business": {
    "name": "XYZ"
  }
}

Controller's method:

Report getData(@RequestBody final Info info){ 
//Some code here... 
} 

Here Info is model class which further have Business class with getter and setter methods

When I POST above request at the time of deserialization first block converted into java object but second one gets simply ignored. I know this is valid json but couldn't understand why 2nd block gets ignored at the time of deserialization .

I tried Deserialization and jackson parser properties but couldn't find any readily available solution. I am using jackson library and Spring Boot framework.

Suggest an approach to achieve this. Thanks!

Answer 1

You are sendind a list so it's better to be in below format:

{
"Businesses" : [
       {"name": "ABC"},
       {"name": "ABC"}
       ]
}

And in case of recieving a list , your method in controller should accept a list:

@POST
@Path("/somePath")
@Consumes({ MediaType.APPLICATION_JSON })
your_method(ArrayList<Business> businesses){
     //...your code
}

Answer 2

因此，您的@RequestBody批注应使用List<Info>而不是Info并且在发送数据时也应使用json列表[{"name": "ABC"},{"name": "XYZ"}]

Answer 3

You can POST a JsonArray like that:

[
    {
      "Business": {
        "name": "ABC"
      }
    }
    {
      "Business": {
        "name": "XYZ"
      }
    }
]

than just loop over the JsonObjects. You can use Google's GSON or what i personally like to use, the MinimalJson ( https://mvnrepository.com/artifact/com.eclipsesource.minimal-json/minimal-json ) dependency to parse objects and determine if they comply the standard.
