java - "Unrecognized token ' com ': was expecting (' 真 ', ' 假 ' or ' 空 ')"

Question

我已经把这个json转成字符串保存在本地数据库

{
        "type": "file",
        "id": "b665ff0b-5f7b-4991-ae88-ac5054880223",
        "link": {
            "href": "https://s3-eu-west-com/87e9edff-e7bd-49ea-aa7a-8948cac29bc1/b665ff0b-5f7b-4991-ae88-ac5054880223.jpg"
        },
        "file_name": "sony 431.jpg",
        "mime_type": "image/jpeg",
        "file_size": 66727,
        "public": true,
        "meta": {
            "dimensions": {
                "width": 1500,
                "height": 1500
            },
            "timestamps": {
                "created_at": "2018-01-22T11:07:35.527Z"
            }
        },
        "links": {
            "current": "https://api.e-com.com/v2/files/b665ff0b-5f7b-4991-ae88-ac5054880223"
        }
    }

当我通过转换为 JSON 来使用该字符串时，出现错误提示

"Unrecognized token 'com': was expecting ('true', 'false' or 'null')"

我该如何解决该错误？

这就是我将此 json 转换为字符串的方式:

staticFile1.setFile(file.toString());

和字符串到json:

File file1 = new ObjectMapper().readValue(file, File.class);

我相信你会遇到这样的错误

Unrecognized token 'com': was expecting ('true', 'false' or 'null')\n at [Source: (String)\"com.jwt.secured.user.ApplicationUser@6d9cce48: Username: justiuser; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; Not granted any authorities\"; line: 1, column: 4]",

com 与字符串中的包引用相关。在类中提供适当的 toString() 实现，并使用 ObjectMapper().writeValueAsString 将其转换为 String。
