我已经基于这个示例成功地制作了一个 Spring MVC 2.5 应用程序：Spring Web MVC - Spring Web Flow Working With JasperReports

但是当我尝试访问使用 IREPORT 5.5 构建的报告的 pdf 视图时，我遇到了这个异常：

Apache Tomcat/6.0.36

我已经一个星期没能解决这个问题了。请帮帮我。

【问题讨论】：

  • 您的 bean 初始化有问题。可以提供war文件吗？
  • 您好 Vitaliy Pro，谢谢您的回复！我已经在 Dropbox 上发布了战争文件，链接是：dropbox.com/s/p3ykhq5fp5ny0c1/mbams.war?dl=0 谢谢！
  • 我已经检查了战争。我不知道问题的原因。但我认为 spring 无法创建 org.springframework.web.servlet.view.jasperreports.JasperReportsPdfView 的 mbamsusers bean 实例，因为 /WEB-INF/reports/SpringJasperReportsspring.jasper 文件不正确或与 jasper 报告库的版本不对应。或者可能是 spring-webmvc.jar 不对应 jasper 报告库。 /lib 目录中有 4 个版本的 jasper 报告：jasperreports-2.0.3.jar、jasperreports-3.5.3.jar、jasperreports-5.5.0.jar、jasperreports-5.6.1.jar。我认为您需要一个 jasper 报告库 jar 文件

标签： java spring-mvc jasper-reports


【解决方案1】：

感谢您的帮助。 你是对的，但我只在类路径中添加了一个版本的 jasperreport。

为了解决问题，我将所有需要的库从 ireport 安装文件夹复制到 lib 文件夹，错误消失了。

commons-beanutils-1.8.2.jar
commons-collections-3.2.1.jar
commons-dbcp-1.2.2.jar
commons-digester-1.7.jar
commons-logging-1.1.jar
commons-pool-1.3.jar
hsqldb-1.8.0-10.jar
iText-2.1.7.jar
jasperreports-4.0.1.jar
jasperreports-chart-themes-4.0.1.jar
jasperreports-extensions-3.5.3.jar
jasperreports-fonts-4.0.1.jar
