Groovy JsonBuilder - 大写属性导致 Mule ESB 中出现意外 token 错误

标签 groovy mule

我正在使用 Mule ESB 的 Groovy 转换步骤中的 JsonBuilder 类创建一个包含 Map、List 和 String 文字数据组合的简单 JSON 文档。

这是我的有效代码

builder {
  Incident {
    number data['number']
    Solution data['close_notes']
    ClosureCode data['close_code']    
    status 'Closed'
    JournalUpdates (
      data['work_notes_list']
    )
  }
}

生成此 JSON

{
"Incident": {
    "number": "INC0011114",
    "Solution": "Returned DVD",
    "ClosureCode": "Solved (Permanently)",
    "status": "Closed",
    "JournalUpdates": [
        "Work Notes1",
        "Work Notes2"
    ]
  }
}

现在奇怪的部分是当我大写属性“status”时，我收到错误。所以这段代码会产生错误。 Status 不是 Groovy 中的保留字，但编译器不喜欢它。

builder {
  Incident {
    number data['number']
    Solution data['close_notes']
    ClosureCode data['close_code']    
    Status 'Closed'
    JournalUpdates (
      data['work_notes_list']
    )
  }
}

这是错误:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script1.groovy: 11: unexpected token: Closed @ line 11, column 12.
   Status 'Closed'
          ^

最佳答案

其中任何一个都可以:

builder {
    Incident {
        number data['number']
        Solution data['close_notes']
        ClosureCode data['close_code']
        Status('Closed')
        JournalUpdates (
                data['work_notes_list']
                )
    }
}

或者:

builder {
    Incident {
        number data['number']
        Solution data['close_notes']
        ClosureCode data['close_code']
        'Status' 'Closed'
        JournalUpdates (
                data['work_notes_list']
                )
    }
}

希望对您有所帮助。
