parameters - Jasper 报表参数显示

Question

我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.报表查询中的参数：$X{IN, alert_type.name, Alert_Type}

1.b 报表中的参数显示：[Alert1, Alert2, ..., Alertn)

在这种情况下，选择的参数显示正确，但我需要将 alert_type.name (varchar) 更改为 alert_type.id (integer)

2.报表查询中的参数：$X{IN, alert_type.id, Alert_Type}

2.b 报表中的参数显示：没有生成报表所以我尝试了3号。

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

3.b 报表中的参数显示：[1,2,3,4....n]

现在的问题是如何在参数中显示 Alert1、Alert2... 而不是 1,2...？所以不想看到 ID 而是看到名称。

以下是请求的相关代码：
