java - 无法从 START_OBJECT token 中反序列化 int[] 实例

Question

大家好，我想将 int 和 String 数组作为 RequestBody 发送:这是 json:

{
    "customUiModel": [1, 3, 5],
    "user": "user"
}

这是端点代码:

@RequestMapping(value = "/save", method = RequestMethod.POST)
      @ResponseStatus(HttpStatus.CREATED)
     public CustomUiModel createCustomUiObject(@RequestBody @Valid int[] customUiModel, String user) {

    return customAppService.saveCustom(customUiModel, user);
}

这是错误:

"message": "JSON parse error: Cannot deserialize instance ofint[]out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance ofint[]out of START_OBJECT token\n at [Source: (PushbackInputStream); line: 1, column: 1]", "path": "/custom/save"

我尝试用数组代替这个 int[] 但我遇到了同样的错误...

创建一个对象而不是int[], String来保存它们，

public class Example {
    private int[] customUiModel;
    private String user;
}

并将 Controller 方法更改为，

public CustomUiModel createCustomUiObject(@RequestBody @Valid Example exe) {}
