java - 没有为映射到名称 'jasper' 的类型 'success' 定义结果类型

Question

我正在将 Jasper Reports 与 Struts 2 结合使用。 在我的 struts.xml 文件中，我已包含

 <package name="billingpkg"  extends="struts-default, json-default,jasperreports-default">
    <action name="myJasperTest" class="iland.bill.SubmitBillAction" method="fetchAll">
            <result name="success" type="jasper">
                <param name="location">/pages/billing/Report1.jasper</param>
                <param name="dataSource">list</param>
                <param name="format">PDF</param>
            </result>
    </action>
  </package>

部署时显示以下错误

1) Error building results for action myJasperTest in namespace
2) There is no result type defined for type 'jasper' mapped with name 'success'

我已将 jasperreport-5.5.0.jar 包含在我的类库中

如何解决上述错误 我收到以下错误堆栈

Answer 1

您需要下载并包含在您的项目中 JasperReports AND struts2-jasperreports-plugin .

从您的评论来看，您似乎只安装了 JasperReports，但没有安装该插件。

还要确保选择相同版本的 Struts2 jar。
