grails - Params.list()提供不正确的值

Question

我试图从参数中获取ID列表，但是当我阅读它们时，最终得到的值与预期值不同。期望值为2和8，最后得到50和56。有人知道这些结果来自何处？

码

println 'Params ' + params
Long[] departments = params.list('departmentIds');
println 'departmentIds ' + departments

输出量

Params [start:2016-02-28, departmentIds:[2, 8], end:2016-04-10, action:calendarRequest, format:json, controller:calendar]
departmentIds [50, 56]

Answer 1

println 'Params ' + params
Long[] departments = params.list('departmentIds').collect { Long.parseLong(it) }
println 'departmentIds ' + departments

或类似的东西...
