Jasper报告参数显示

Question

我已经尝试了几个参数显示选项：

alert_type.name --> varchar
alert_type.id --> integer
Alert_Type --> java.util.collection

1.a报告查询中的参数：     $ X {IN，alert_type.name，Alert_Type}

1.b报告中的参数显示： [Alert1，Alert2，...，Alertn）

在这种情况下，所选参数显示正确但我需要将alert_type.name（varchar）更改为alert_type.id（整数）

2.a报告查询中的参数：     $ X {IN，alert_type.id，Alert_Type}

2.b报告中的参数显示： 报告没有生成，所以我尝试了第3号。

3.a报告查询：     $ X {IN，COALESCE（CAST（alert_type.id AS varchar（100））），Alert_Type}

3.b报告中的参数显示： [1,2,3,4 .... n]的

现在问题是如何在参数中显示Alert1，Alert2 ......而不是1,2 ......？所以不要看ID而是名字。

以下是所请求的相关代码：
