无法反序列化START_OBJECT标记外的`java.lang.boolean'实例

Question

下面是put请求的控制器映射：

@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);  
}

当我运行以下来自邮递员的请求时：

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，但我不明白我错过了什么？

我试着在邮递员上用这样的真或假。没关系。
