[英]List into other List jasper report
I have this object structure, to use like Java Bean in mi jasper report,我有这个对象结构,在 mi jasper 报告中像 Java Bean 一样使用,
public class Person{
private String name;
private String lastname;
private List<Job> jobs;
}
public class Job{
private String jobName;
private String companyName;
private List<Reponsability> responsabilities;
}
All class with corresponding setters
and getters
所有具有相应
setters
和getters
When I create a list into jasper report I define the "job list" JRDataSource expression
this way:当我在 jasper 报告中创建一个列表时,我以这种方式定义了“作业列表”
JRDataSource expression
:
new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{jobs})
Now I want to create another list, "responsibilities list" on the "job list" , the question is:现在我想在“工作列表”上创建另一个列表, “职责列表” ,问题是:
How can I define the data source to get the corresponding job to pass into the JRDataSource Expression
?如何定义数据源以获取相应的作业以传递到
JRDataSource Expression
?
I imagine something like this:我想象这样的事情:
new JRBeanCollectionDataSource(${jobs}.get($index).getResponsabilities())
but I can't get it work this但我不能让它工作
I found the solution to do this:我找到了解决方案来做到这一点:
Into the list, I created a variable called jobInstance进入列表,我创建了一个名为jobInstance的变量
<field name="jobInstance" class="com.mypackage.example.Job">
<fieldDescription><![CDATA[_THIS]]></fieldDescription>
</field>
Then when I set the datasource for responsibilities list did this:然后当我为职责列表设置数据源时:
new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{jobInstance}.getResponsabilities())
