我使用com.github.fge.jsonschema.main.JsonSchema来验证json。
这是json模式:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "Team data",
"description": "Validation schema",
"type": "object",
"additionalProperties": false,
"required": [
],
"properties": {
"name": {
"type": "string",
"minLength": 2,
"maxLength": 255,
"description": "Name"
}
}
}
这是用于验证架构的json:
{"name" : "name"}
这是有效的,当我使用在线验证器进行检查时,但在测试中却出现错误:
Caused by: com.github.fge.jsonschema.core.exceptions.InvalidSchemaException: fatal: invalid JSON Schema, cannot continue
Syntax errors:

我看不到错误在哪里。

好吧,错误似乎出在您的方案中,而不是在要验证的文件中。必需的属性是数组类型,但是数组没有元素。
当您删除属性required
或提供至少一个字符串元素以指示应要求哪些属性时,验证就会成功:
"required": [
"name"
]
自JSON Schema documentation的草案4起,该数组必须至少包含一个元素。
