在报告中显示字符串列表

Question

我对 JasperReports 有点新鲜。我正在尝试使用 iReport 在示例报告的其中一列中打印名称列表。虽然列表正确显示但它没有按照需要提供输出格式。

收到的输出：

Merchant Name                              Fruits Sold
Marx                                       [Fiji apple,  Kashmir apple, Shimla apple]
Stalin                                     [Fiji apple,  Kashmir apple, Shimla apple]

预期输出应为：

Merchant Name                             Fruits Sold
Marx                                      Fiji apple
                                          Kashmir apple
                                          Shimla apple

Stalin                                    Fiji apple
                                          Kashmir apple
                                          Shimla apple

我在报告中为“售完水果”栏使用了一个List元素。在列表框架中，我将来自Javabean的文本字段元素$ {fruitsForSale}。 List元素的连接表达式为$ P {REPORT_CONNECTION}，以使用与主数据集相同的连接。

Javabean类如下：

import java.util.ArrayList;
import java.util.List;

public class FruitSeller {
  private String merchantName;
  private List<String> fruitsForSale;

  public String getMerchantName() {
    return this.merchantName;
  }

  public void setMerchantName(String merchantName) {
    this.merchantName = merchantName;
  }

  public List<String> getFruitsForSale() {
    return this.fruitsForSale;
  }
  public void setFruitsForSale(List<String> fruitsForSale) {
    this.fruitsForSale = fruitsForSale;
  }
  public static List<FruitSeller> prepareReport() {
    List fruitSellerList = new ArrayList();

    FruitSeller fruitSeller = new FruitSeller();
    fruitSeller.setMerchantName("Marx");
    List fruitsForSale = new ArrayList();
    fruitsForSale.add("Fiji apple");
    fruitsForSale.add("Kashmir apple");
    fruitsForSale.add("Shimla apple");
    fruitSeller.setFruitsForSale(fruitsForSale);
    fruitSellerList.add(fruitSeller);

    FruitSeller fruitSeller2 = new FruitSeller();
    List fruitsForSale2 = new ArrayList();
    fruitSeller2.setMerchantName("Stalin");
    fruitsForSale2.add("Fiji apple");
    fruitsForSale2.add("Kashmir apple");
    fruitsForSale2.add("Shimla apple");
    fruitSeller2.setFruitsForSale(fruitsForSale2);
    fruitSellerList.add(fruitSeller2);
    return fruitSellerList;
  }
}

jrxml文件如下：

任何人都可以建议我可能出错的地方吗？
