创建Spring和#180的实例；Kotlin中的参数化类型引用

我正在努力学习Kotlin ，并测试它如何与弹簧靴一起工作.我的应用程序使用mongo数据库来存储数据，我有一个Jersey资源来检索数据.我正在用spring-boot-test和RestTestTemplate测试它.

RestTestTemplate有一个exchange方法，需要ParameterizedTypeReference.这个类有一个受保护的构造函数.所以我从Kotlin那里用它的唯一方法是:

class ListOfPeople : ParameterizedTypeReference<List<Person>>()个

以下是我的测试方法:

@Test
fun `get list of people`() {
    // create testdata
    datastore.save(Person(firstname = "test1", lastname = "lastname1"))
    datastore.save(Person(firstname = "test2", lastname = "lastname2"))
    datastore.save(Person(firstname = "test3", lastname = "lastname2"))
    datastore.save(Person(firstname = "test4", lastname = "lastname2"))

    val requestEntity = RequestEntity<Any>(HttpMethod.GET, URI.create("/person"))

    // create typereference for response de-serialization
    class ListOfPeople : ParameterizedTypeReference<List<Person>>() // can this be done inline in the exchange method?
    val responseEntity : ResponseEntity<List<Person>> = restTemplate.exchange(requestEntity, ListOfPeople())

    assertNotNull(responseEntity)
    assertEquals(200, responseEntity.statusCodeValue)
    assertTrue( responseEntity.body.size >= 4 )

    responseEntity.body.forEach { person ->
        println("Found person: [${person.firstname} ${person.lastname}] " +
                ", born [${person.birthdate}]")
    }
}

这是正确的(或唯一的)方法吗，还是有更好的方法？
