DynamicJasper：如何修复 java.lang.NoSuchMethodError 错误

Question

我有一个动态碧玉报告的例子。

我正在使用 NetBeans IDE。

我包含库文件如下：

Dynamic-jasper-3.2.1.jar
Dynamic-jasper-3.2.1-test.jar
jasperreport-4.5.jar
commons-beanutils-1.8.2.jar 
commons-collections-3.2.1.jar 
commons-digester-1.7.jar 
commons-logging-1.1.jar 
junit-3.8.2.jar

import java.util.Date;
import net.sf.jasperreports.view.JasperDesignViewer;
import net.sf.jasperreports.view.JasperViewer;
import ar.com.fdvs.dj.domain.DynamicReport;
import ar.com.fdvs.dj.domain.builders.FastReportBuilder;
import ar.com.fdvs.dj.test.BaseDjReportTest;

public class FastReportTest extends BaseDjReportTest {
    public DynamicReport buildReport() throws Exception {

        FastReportBuilder drb = new FastReportBuilder();
        drb.addColumn("State", "state", String.class.getName(), 30)
                .addColumn("Branch", "branch", String.class.getName(), 30)
                .addColumn("Product Line", "productLine", String.class.getName(), 50)
                .addColumn("Item", "item", String.class.getName(), 50)
                .addColumn("Item Code", "id", Long.class.getName(), 30, true)
                .addColumn("Quantity", "quantity", Long.class.getName(), 60, true)
                .addColumn("Amount", "amount", Float.class.getName(), 70, true)
                .addGroups(2)
                .setTitle("November \"2006\" sales report")
                .setSubtitle("This report was generated at " + new Date())
                .setPrintBackgroundOnOddRows(true)
                .setUseFullPageWidth(true);

        DynamicReport dr = drb.build();
        return dr;
    }

    public static void main(String a[]) throws Exception {
        FastReportTest test = new FastReportTest();
        // test.
        test.testReport();
        test.exportToJRXML();
        JasperViewer.viewReport(test.jp);    //finally display the report report
        JasperDesignViewer.viewReportDesign(test.jr);
    }
}

我遇到这样的错误：

如果您使用的是 DynamicJasper 3.2.1，您应该使用 DJ 的 pom.xml 中的外部库。

pom.xml 文件的片段：

    <dependency>
        <groupId>jasperreports</groupId>
        <artifactId>jasperreports</artifactId>
        <version>3.7.1</version>

            <exclusion>

    </dependency>

如您所见，此版本 (3.2.1) 的 DJ API 使用 jasperreports 3.7.1 等。
