grails - grails根据相应的字符串查找arraylist字符串

Question

我有一个方法:

def nameToCode(nameStr){
    def ret = resortService.getResort("all")
    //this gets like 180 objects with various properties like name, code, etc.
    def resorts = [name: ret.prName, code: ret.prProductIndex]
    def code = resorts.findByName(nameStr) //this doesn't work
    println(code)
    return code
 }

我正在尝试调用此方法并为其发送名称。然后应该在 map 上找到名称，如果找到了它，则应该返回名称的代码。这本来应该很简单，但是我一直到处搜索，却不知道该怎么做。我将不胜感激。谢谢

您在标准 map 上使用gorm方法:
代替 :

 def resorts = [name: ret.prName, code: ret.prProductIndex]
    def code = resorts.findByName(nameStr) //this doesn't work

尝试:

 def resorts = [name: ret.prName, code: ret.prProductIndex]
    def code = resorts.findAll{name==nameStr}
