javax.el.ELException 未找到方法

Question

我正在开发一个使用 Primefaces JSF 的 Web 应用程序，在前端使用托管 bean，在后端使用 SQL 服务器。我已经开发该应用程序 2 个月了，并在我们办公室的不同环境中对其进行了测试。不同的环境是指不同的 java 7 版本和 Tomcat 7 版本，一切都运行良好。试图从我的家用 PC 继续开发，但现在出现错误

javax.el.ELException: /custsession_detailed.xhtml @67,122 value="#{IdToString.returnPackagetName(SearchComponent.returnCustomerProfile().packagesSegment) }": 找不到方法: class al.durandal.com.jsf.IdToStringTypeComponent.returnPackagetName(java.lang.String)

我 100% 确定方法就在那里。在这两种环境中，Java 版本和 Tomcat 版本是相同的。

package al.durandal.com.jsf;

    }

    public StatusType getStatusType() {
        return statusType;
    }



    public void setSatusType(StatusType statType) {
        this.statusType = statType;
    }

    @Transactional
    public StatusType loadStatusTypeByPrimaryKey(Integer sidKey) {
        statusType = statusTypeDAO.findStatusTypeByPrimaryKey(sidKey);

        return statusType;
    }

    public String returnProductName(Integer statusCode){


        statusType=statusTypeDAO.findStatusTypeByPrimaryKey(statusCode);
        if(statusType!=null)
        return statusType.getStatusName();
        else

    }

        packageType =packagesTypeDAO.findPackagesTypeByIdPackage(pkgCode);

        if(packageType!=null)
            return packageType.getName();
        else
            return "Not Available";
    }


    @Override

        statusType= new StatusType();



    }


    public void setStatusValues(int statusId){
        System.out.println("statusId "+statusId);
        statusType = new StatusType();
        statusType = loadStatusTypeByPrimaryKey(statusId);
        System.out.println("statusType" + statusType);
        System.out.println("Ja ku jam ketu");
        setSatusType(statusType);


    }

    public int setMaxStatusType(){
        int statusTypeNo=statusTypeService.countStatusTypeMax();
        statusType = new StatusType();
        System.out.println("statusTypeNo "  +statusTypeNo);
        statusType.setSid(statusTypeNo);
        return statusTypeNo;
    }


    @Transactional
    public void saveStatusType(StatusType statustype) {

        logger.info("Saving Status Type: "+statustype.toString());
        FacesMessage message = null;
        FacesContext context = FacesContext.getCurrentInstance();
        boolean save=false;
        try {

            statusTypeService.saveStatusType(statustype);
            logger.info("Saving...");

            //statustype.unset();

            //statusType.setSid(statusTypeService.countStatusTypeMax());
            //
            //statustype.setSid(statusTypeService.countStatusTypes());

            save = true;


        }
        catch(Exception e)
        {   
            logger.info("FAILED during saving...");
            logger.info("Excpetions are: "+e.toString());
            throw e;
        }

     if(save) {
            message = new FacesMessage(FacesMessage.SEVERITY_INFO, "OK!","Saved Succesfully !");

        } else {
            message = new FacesMessage(FacesMessage.SEVERITY_WARN, "Error!", "Unable to save !");


        }
        context.addMessage(null,message );

    }


}

Answer 1

问题出在这一行

<h:outputText value="#{IdToString.returnPackagetName(SearchComponent.returnCustomerProfile().packagesSegment)}" />

并且日志显示正在查找的方法接受 String 参数

returnPackagetName(java.lang.String)

而您的 bean 中的方法接受 Integer

returnPackagetName(Integer pkgCode)
