推荐答案
你的java bean必须是这样的（对应的）到您的 subDataset 命名为javabean）。
Your java bean needs to be something like this (correspond to your subDataset named javabean).
public class JavaBean {
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
然后你需要一个 List< ; JavaBean> 的JavaBean。
Then you need a List<JavaBean> of the JavaBean's.
让我们假设您将此列表传递为填充过程中的参数（在参数映射中使用键 listOfJavaBeans ）。
Lets imagine that you pass this List as a parameter during the fill process (in the parameter map with the key listOfJavaBeans).
in jrxml 定义参数
<parameter name="listOfJavaBeans" class="java.util.List"/>
将其传递到您的表作为数据源使用。
<datasetRun subDataset="javabean" uuid="31830583-c665-4c8d-af3a-1a5a0aba5306">
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{listOfJavaBeans})]]></dataSourceExpression>
</datasetRun>
