java - 无法从START_OBJECT token 中反序列化java.lang.Boolean的实例

这是我的Put请求的Controller映射：

@PutMapping("/voteForPostByUser")
    public String vote(@RequestParam(value = "postId", required =
true) String postId, @RequestParam(value = "userId", required = true)
Integer userId, @RequestBody Boolean vote) {

        BlogPostVoteDTO blogPostVoteDTO = new BlogPostVoteDTO
(postId, userId, vote);
        return
this.blogPostService.updateBlogPostVotes(blogPostVoteDTO);
}

当我从POSTMAN运行以下请求时：

http://localhost:8082/microblog/api/voteForPostByUser?postId=5d564a2638195729900df9a6&userId=5

Request Body:
{
        "vote" : true
    }

我得到以下异常

"status": 400,
    "error": "Bad Request",
    "message": "JSON parse error: Cannot deserialize instance of
`java.lang.Boolean` out of START_OBJECT token; nested exception is
com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot
deserialize instance of `java.lang.Boolean` out of START_OBJECT token\n
at [Source: (PushbackInputStream); line: 1, column: 1]",
    "trace":
"org.springframework.http.converter.HttpMessageNotReadableException: JSON
parse error: Cannot deserialize instance of `java.lang.Boolean` out of
START_OBJECT token; nested exception is
com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot
deserialize instance of `java.lang.Boolean` out of START_OBJECT token\n
at [Source: (PushbackInputStream); line: 1, column: 1]\r\n\tat

我可能很简单，但我不明白我想念的是什么？

最佳答案

我像这样使用true或false尝试邮递员，没关系。
