In Micronaut Controller parsing the post request using JSON object. I expect it to not include quotes, but it quotes in the database insert.

Posting like this:

curl -X POST --header "Content-Type: application/json" -d '{"bookid":3,"name":"C++"}'  http://localhost:8880/book/save

Saving like this:

String bookid=JSON?.bookid

  String name=JSON?.name

def b =bookService.save(bookid,name

in database It stores like this:

+--------+-------+

| bookid | name  |

+--------+-------+

| 3      | "C++" |

+--------+-------+

I expect book name just C++

Thanks

You haven't provided enough information about your project to know what is going on but the project at https://github.com/jeffbrown/sfgroupsjsonbinding/tree/master demonstrates how the built in binding stuff works. See the README.md file there.

https://github.com/jeffbrown/sfgroupsjsonbinding/blob/3ff4e8b39ba5fda9956ebfc67cd0b9e5d940b8f2/src/main/groovy/sfgroupsjsonbinding/BookController.groovy

package sfgroupsjsonbinding



import io.micronaut.http.annotation.Controller

import io.micronaut.http.annotation.Get

import io.micronaut.http.annotation.Post



@Controller('/book')

class BookController {



    private PersonService personService



    BookController(PersonService personService) {

        this.personService = personService

    }



    @Get('/')

    List<Person> list() {

        personService.list()

    }



    @Post('/')

    Person save(Person person) {

        personService.save person

    }



    @Get('/{id}')

    Person get(long id) {

        personService.get id

    }

}

Interacting With The App

 $ curl -H "Content-Type: application/json" -d '{"name":"Jeff"}' http://localhost:8080/book

{"name":"Jeff","id":1}

 $ 

 $ curl -H "Content-Type: application/json" -d '{"name":"Jake"}' http://localhost:8080/book

{"name":"Jake","id":2}

 $ 

 $ curl -H "Content-Type: application/json" -d '{"name":"Zack"}' http://localhost:8080/book

{"name":"Zack","id":3}

 $ 

 $ curl http://localhost:8080/book

[{"name":"Jeff","id":1},{"name":"Jake","id":2},{"name":"Zack","id":3}]

 $ 

 $ curl http://localhost:8080/book/1

{"name":"Jeff","id":1}

 $ 

 $ curl http://localhost:8080/book/2

{"name":"Jake","id":2}

 $ 

 $ curl http://localhost:8080/book/3

{"name":"Zack","id":3}

I know i am a bit late but i've been searching for the solution for long and didnt find anything. After a lot of effort i found that sending jackson "Object" with "@BODY" is not helpful, when i changed the the type to "String" it worked for me.

Here is my Code

def save(@Body String JSON){



    def result = [:]

    ObjectMapper objectMapper = new ObjectMapper();



    //convert json string to object

    def obj = objectMapper.readValue(JSON, Course.class);

    println(obj)



    Course course = new Course(name: obj?.name, pre: obj?.pre,

            regno: obj?.regno, enrolled: obj?.enrolled)



    course.validate()

    if(course.hasErrors()){

        println("Error: "+course.errors)

        result.put("Error is: ",course.errors)

        return result;

    }



    course.save(flush:true,failOnError: true)



    result.put("Message","Successfully Created")

    result.put("Result",course)

    return HttpResponse.created(result)

}

Passing it to ObjectMapper and then converting it from JSON string to Java Object worked for me.

Json string that i passed is as follow:

{

 "name" : "Data Structures",

 "pre" : "Computer Programming",

 "regno" : "249",

 "enrolled" : "90"

}

Here is the storing of data before and after change in database:

+----+---------+------------------------+-------------------------------+----+

| id | version |        name      |   pre       |     regno        |enrolled |

+----+---------+------------------------+-------------------------------+----+

|  1 | 0 | "Computer Programming" | "Introduction to Programming"| "233"|"26"|

|  2 | 0 | Data Structures        | Computer Programming         |  249 | 90 |

+----+---------+------------------------+-------------------------------+----+

Hope the answer helps out anyone who is looking for alternate solution to above solution.
