Spring MVC获取JR报告异常

我正在做一个控制器，以便在用户需要时显示JR报告。我正在使用Maven + Eclipse + JasperReports API。Spring MVC获取JR报告异常

该项目编译好，但是当我尝试访问我的控制器，以获得该报告，我看到这个异常：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'reciboPago': Initialization of bean failed; nested exception is org.springframework.context.ApplicationContextException: Could not parse JasperReports report from ServletContext resource [/WEB-INF/classes/config/reports/IntegracionCGC.jasper]; nested exception is net.sf.jasperreports.engine.JRException: Error loading object from InputStream

这里是我的控制器：

@Controller 
@RequestMapping("/pago") 
public class JasperReportsController { 

    public static final Log logger = LogFactory.getLog(JasperReportsController.class); 

    @RequestMapping(value = "/recibo", method = RequestMethod.GET) 
    public String generarReciboPago(ModelMap modelMap, HttpServletResponse response) { 
    List<ReciboPagoJasperDTO> lista = new ArrayList<ReciboPagoJasperDTO>(1); 
    ReciboPagoJasperDTO dto = new ReciboPagoJasperDTO(); 
    dto.setMonto("6789.0"); 
    dto.setNombre("Pedro Romero"); 
    lista.add(dto); 
    // response.setHeader("Content-type", "application/pdf"); 
    // response.setHeader("Content-Disposition","attachment; filename=\"recibo.pdf\""); 
    JRBeanCollectionDataSource jrbean = new JRBeanCollectionDataSource(lista, false); 
    modelMap.put("reciboKey", jrbean); 
    return ("reciboPago"); 
    } 

    @RequestMapping(method = RequestMethod.GET, value = "docx") 
    public ModelAndView generateDocxReport(ModelAndView modelAndView) { 
    logger.debug("--Generating docx report--"); 
    Map<String, Object> parameterMap = new HashMap<String,Object>(); 

    List<ReciboPagoJasperDTO> lista = new ArrayList<ReciboPagoJasperDTO>(1); 
    ReciboPagoJasperDTO dto = new ReciboPagoJasperDTO(); 
    dto.setMonto("6789.0"); 
    dto.setNombre("Pedro Romero"); 
    lista.add(dto); 

    JRDataSource JRdataSource = new JRBeanCollectionDataSource(lista); 
    parameterMap.put("datasource", JRdataSource); 

    modelAndView = new ModelAndView("docxReport", parameterMap); 
    return modelAndView; 
    } 
}

对此有何建议？

你可以添加视图的Spring配置吗？ – madth3

这是在下面的链接类似于一个 http://stackoverflow.com/questions/5421879/objectinputstream-happy-with-fileinputstream-not-happy-with-getresourceasstream – Hemanth

最后我得到了解决方案。我将此添加到我的POM中。我希望这对其他人有效。

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-resources-plugin</artifactId> 
    <version>2.6</version> 
    <configuration> 

     <nonFilteredFileExtensions> 
     <nonFilteredFileExtension>jasper</nonFilteredFileExtension> 
     </nonFilteredFileExtensions> 

    </configuration> 
    </plugin>

问候！
