Parameters Jasper报告参数显示

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.报表查询中的一个参数： $X{IN，警报类型.name，警报类型}

1.b报告中的参数显示： [Alert1，Alert2，…，Alertn）

在本例中，选择了正确显示的参数，但我需要将alert_type.name（varchar）更改为alert_type.id（integer）

2.报表查询中的一个参数： $X{IN，警报类型.id，警报类型}

2.b报告中的参数显示： 报告没有生成，所以我尝试了第3项中的内容

3.报表查询： $X{IN，COALESCE（强制转换（alert_type.id为varchar（100）），alert_type}

3.b报告中的参数显示： [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…？因此不希望看到ID，而是名称

以下是请求的相关代码：

你能发布你的jrxml代码吗？@user2477868

现在的问题是我如何在参数中显示Alert1、Alert2…而不是1,2…？

-你是说在生成的报告（输出文件）中打印参数的值吗？是的，我想打印生成报告中的参数值。原始问题中添加了jrxml代码。有人能在这方面帮助mne吗？
