Json 为RestController配置ObjectMapper

我的Spring boot应用程序中有两个控制器：RestControllerA使用snake_case返回JSON，RestController2使用camelCase返回JSON

有没有一种方法可以轻松地配置它？我现在正在做这样丑陋的事情：

@RestController
class RestControllerA(
    @Qualifier("objectMapperSnakeCase")
    private val objectMapperSnakeCase: ObjectMapper <-- I shouldn't have to inject this in.
) {
  @GetMapping("/test-endpoint-1")
  fun endpoint1(): ResponseEntity<String> { <-- I shouldn't have to return a string.
    val employee = Employee(...)
    val jsonString = objectMapperSnakeCase.writeValueAsString(employee)
    return ResponseEntity.ok().body(jsonString)
  }
}

@RestController
class RestControllerB(
    @Qualifier("objectMapperCamelCase")
    private val objectMapperCamelCase: ObjectMapper <-- I shouldn't have to inject this in.
) {
  @GetMapping("/test-endpoint-2")
  fun endpoint2(): ResponseEntity<String> { <-- I shouldn't have to return a string.
    val employee = Employee(...)
    val jsonString = objectMapperCamelCase.writeValueAsString(employee)
    return ResponseEntity.ok().body(jsonString)
  }
}

@RestController
类RestControllerA(
@限定符（“objectMapperSnakeCase”）
私有val objectMapperSnakeCase:ObjectMapper
@RestController
class RestControllerA {
  @GetMapping("/test-endpoint-1")
  @ObjectMapperToUse("objectMapperSnakeCase") <-- Nice and easy.
  fun endpoint1(): Employee {
    return Employee(...)
  }
}

// Similar for RestControllerB with objectMapperCamelCase
