Question

我正在尝试使用Java（Web应用程序）打印条形码并使用Jaspoersoft iReport Designer 4.5.0

这是我的Java代码：

public String onBtnPrintClick() throws JRException, IOException {
    Integer pos_number = getMst_posService().getPosById((Integer) getSession().get("pos_id")).getPos_number();
    Date dateNow = new Date();
    SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    Integer total_paid = getPaidCard() + getPaidCash();

//      Bill printing   


    View_transactionprod_pos transactionProdToBill = new View_transactionprod_pos();
    transactionProdToBill.setTransaction_id(getTransactionIdFromMakeSale());

    listProdToBill = getView_transactionprod_posService().getViewTransactionProdPosListByModel(transactionProdToBill);

    Map<String, Object> parameters = new HashMap<String,Object>();
    parameters.put("transaction_id", getTransactionIdFromMakeSale());
    parameters.put("pos_number", pos_number);
    parameters.put("transaction_date", dateFormatter.format(dateNow));
    parameters.put("total_price", getTotalPriceToSell());
    parameters.put("total_paid", total_paid);
    parameters.put("change", getChange());
    parameters.put("barcode", getTransactionIdFromMakeSale());

    return "pdf";
}

xml：

    <action name="MakeSalePrint" class="MakeSaleS" method="onBtnPrintClick">
        <result name="input">/WEB-INF/jsp/makesale.jsp</result>
        <result name="success" type="json">/WEB-INF/jsp/makesale.jsp</result>
        <result name="pdf" type="jasper">
            <param name="location">/WEB-INF/report/Bill.jasper</param>
            <param name="dataSource">listProdToBill</param>
            <param name="format">PDF</param>
            <param name="documentName">reportDetail</param>
            <param name="reportParameters">parameters</param>
        </result>
    </action>

单击打印按钮时调用onBtnPrintClick()方法。我已经导入了一些罐子并将其添加到我的项目中：

Added to my project from myproject/src/main/webapp/lib

在jrxml文件中条形码是 code128 ，语言是java

没有条形码打印..

我无法从barcode4j-2.1.jar找到错误类

错误：

Answer 1

检查org / krysalis / barcode4j / HumanReadablePlacement类是否在你的jar中，容器（tomcat或其他）加载它。

Answer 2

尝试更新pom.xml：

<dependency>
    <groupId>net.sf.barcode4j</groupId>
    <artifactId>barcode4j</artifactId>
    <version>2.1</version>
</dependency>

您认为此答案有用时，版本可能会更高。

如何在jasperReports上修复barcode4j-2.1.jar中的java.lang.NoClassDefFoundError？
