在jasper报告中显示Grails列表属性

我不知道如何在jasper报告中使用Grails呈现列表属性

我的域类看起来像这样：

class Project {


String name
String division
List divisions

String toString(){
    "$name"
}


static hasMany = [divisions : Division ]
...

分区域类来到这里

class Division {

String name
String divisionResponsible
String createDate

...

项目控制器看起来像这样

class ProjectController {


def scaffold = true

def index = {
    redirect(action : list)
}


def createReport = {

    def projectreport = Project.getAll([params.project_id])
    chain(controller:'jasper',action:'index',model:[data:projectreport],params:params)

}

}

我用iReport创建了一个jasper报告，效果很好。我添加了列表中的字段，并通过访问例如$ F {name}，但我不知道如何添加分区列表。我想要一个每行一个元素的列表。

UPDATE 添加了jrxml文件：

  <?xml version="1.0" encoding="UTF-8"?>

更新2：

我设法通过在jasper报告中使用以下变量来访问列表元素

 $F{divisions.[0].name}
 $F{divisions.[1].name}

问题是现在这在实际报告中并不真正可用，因为我不知道列表中有多少元素。

有没有办法迭代jasper报告中的列表元素？

1 个答案:

答案 0 :(得分：0)

您是否尝试过使用

<printWhenExpression><![CDATA[$F{data}.get(0) != null]]></printWhenExpression>
<textFieldExpression><![CDATA[$F{data}.get(0).name]]></textFieldExpression>

分裂：

<printWhenExpression><![CDATA[$F{data}.get(0).divisions != null && $F{data}.get(0).divisions.get(0) != null]]></printWhenExpression>
<textFieldExpression><![CDATA[$F{data}.get(0).divisions.get(0).name]]></textFieldExpression>
