Question

我正在尝试在Mule流中使用Validate JSON模式组件，并且我正在为传递的json获取com.fasterxml.jackson.core.JsonParseException。下面是json模式，json示例和Mule流程的代码。你能指点我在哪里做错了吗？

Json架构：

{
   "$schema": "http://json-schema.org/draft-04/schema#",
   "title": "Product",
   "description": "A product from Acme's catalog",
   "type": "object",

   "properties": {

      "id": {
         "description": "The unique identifier for a product",
         "type": "integer"
      },

      "name": {
         "description": "Name of the product",
         "type": "string"
      },

      "price": {
         "type": "number",
         "minimum": 0,
         "exclusiveMinimum": true
      }
   },

   "required": ["id", "name", "price"]
}

Json传递给POST方法：

[
   {
      "id": 2,
      "name": "An ice sculpture",
      "price": 12.50,
   },

   {
      "id": 3,
      "name": "A blue mouse",
      "price": 25.50,
   }
]

错误：

Root Exception stack trace:
com.fasterxml.jackson.core.JsonParseException: Unexpected character ('}' (code 125)): was expecting double-quote to start field name
 at [Source: java.io.InputStreamReader@6e7f030; line: 6, column: 5]
    at com.fasterxml.jackson.core.JsonParser._constructError(JsonParser.java:1419)
    at com.fasterxml.jackson.core.base.ParserMinimalBase._reportError(ParserMinimalBase.java:508)

骡流：

<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/>
    <flow name="jsonschemavalidationFlow">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/" allowedMethods="POST" doc:name="HTTP"/>
        <json:validate-schema schemaLocation="jsonschema.json" doc:name="Validate JSON Schema"/>
        <logger message="#[payload]" level="INFO" doc:name="Logger"/>
    </flow>

Answer 1

json u r传球不合适。它有一个额外的逗号'，'价格后：12.50。即使在第二个价格元素之后，也会添加额外的逗号。只需删除它，它工作正常。

Answer 2

JSON和Schema中的错误如下： - 在,之后还有一个额外的逗号"price": 12.50 所以Valid JSON将是： -

[
   {
      "id": 2,
      "name": "An ice sculpture",
      "price": 12.50
   },

   {
      "id": 3,
      "name": "A blue mouse",
      "price": 25.50
   }
]

在JSON架构文件中 jsonschema.json 有两个错误： -
您需要输入＆＃34; type": "array"而不是"type": "object" 这个JSON输入似乎无效"exclusiveMinimum": true ... 因此，正确的工作JSON模式将是： -

{
   "$schema": "http://json-schema.org/draft-04/schema#",
   "title": "Product",
   "description": "A product from Acme's catalog",
   "type": "array",

   "properties": {

      "id": {
         "description": "The unique identifier for a product",
         "type": "integer"
      },

      "name": {
         "description": "Name of the product",
         "type": "string"
      },

      "price": {
         "type": "number",
         "minimum": 0
      }
   },

   "required": ["id", "name", "price"]
}

试试吧..它会正常工作：）
