在我的JasperReport报告中,只显示我的收藏的第一行。这是相关的代码。
实体
public class LegendEntity implements Serializable{
private String label;
private Image bufferedImage;
public LegendEntity() {
}
public LegendEntity(String label) {
this.label = label;
}
public LegendEntity(String label,Image bufferedImage) {
this.label = label;
this.bufferedImage = bufferedImage;
}
//getters-setters
准备数据源:
List<MyEntity> myEntitiesList = new ArrayList<>();
//filling the list
JRBeanCollectionDataSource entityDS= new JRBeanCollectionDataSource(myEntitiesList ,false);
report.getReportParameters().put("ENTITY_DATASOURCE", entityDS);

在报告中,仅显示第一个实体的标签和符号。我错过了什么?
调试已经完成,我确信列表中存在1个以上的实体。
整个JRXML here。
答案 0 :(得分:0)
我注意到你的主要JRXML中至少有两个问题:
printOrder="Horizontal"
可能会阻止正常的元素溢出。请尝试恢复为printOrder="Vertical"
或完全删除该属性。答案 1 :(得分:0)
您可以尝试将变量放在表格的白色区域中。不在蓝色/标题区域。
它对我有用。
