kotlin data class 和泛型JSON.parseObject<Entity>(json)的bug[BUG] #1491
Description
kotlin 中解析 data class的问题，是不支持kotlin还是bug呢
1.使用val data = JSON.parseObject<Entity>(json) 会报错
2.val data = JSON.parseObject(json,Entity::class.java)解析不出来，结果是显示默认值，如果entity没有默认值就报错
3.不指定泛型JSON.parseObject(json) 或者 实体类用 class 则不会报错，data class Entity(
val name: String = "", val age: Int = 0
)
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val json = """
{
"age":5,
"name":"1234243"
}
""".trimIndent()
val data = json.parseObject<Entity>()
// val data = JSON.parseObject<Entity>(json)
// val data = JSON.parseObject(json,Entity::class.java)
Log.w("=========>>", "======>>>data:${data}")
}
}
