Groovy在创建动态json时没有这样的属性错误

Question

def builder = new groovy.json.JsonBuilder()

@groovy.transform.Immutable

    String Id
    String Name
}

def items = new File("Item.txt").readLines().collect { line -> new Items(line.split(",")[0], line.split(",")[1]) }

CSV如下：

   -1,BatteryStatus
    -3,AvailableMemory
    -5,AvailableStorage

提前谢谢你

Answer 1

这里必须使用{}作为闭包：

items.collect() { // wrong: [
    // ...
} // wrong: ]

或者只是项。收集{...}

使用[]，编译器将看到它作为一个映射文本，并得到上面的错误(It未定义）
