具有复合(两部分)主键的Glassfish / PostgreSQL表生成com.sun.jersey.spi.inject.Errors

我有一个PostgreSQL表testtable,其中包含bigint类型的两部分主键(ID1,bigint类型的ID2)和带有时间戳的非键字段。我正在尝试使用“来自数据库的新RESTful Web服务”向导生成RESTful Web服务,并且除了包名称(服务)选择所有值的默认值之外。该向导生成四个文件:

  • AbstractFacade.java
  • Testtable.java
  • TesttableREST.java
  • TesttablePK.java

部署到服务器并选择“测试RESTful Web服务”,测试页无法加载:

exception 
javax.servlet.ServletException: PWC1391: Servlet.init() for servlet org.netbeans.rest.application.config.ApplicationConfig threw exception

root cause 
com.sun.jersey.spi.inject.Errors$ErrorMessagesException

查看glassfish事件日志,有两个严重错误:

The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Missing dependency for method public void service.TesttableFacadeREST.remove(service.TesttablePK) at parameter at index 0
SEVERE: Method, public void service.TesttableFacadeREST.remove(service.TesttablePK), annotated with DELETE of resource, class service.TesttableFacadeREST, is not recognized as valid resource method.
SEVERE: Missing dependency for method public service.Testtable service.TesttableFacadeREST.find(service.TesttablePK) at parameter at index 0
SEVERE: Method, public service.Testtable service.TesttableFacadeREST.find(service.TesttablePK), annotated with GET of resource, class service.TesttableFacadeREST, is not recognized as valid resource method.

在我开始使用NetBeans提交错误报告之前,我只是想知道这是否更可能是开发人员错误,而不是开发人员工具集的错误。想法?

  • 数据库:PostgreSQL 8.4
  • App Server:Glassfish 3.1.2.2
  • IDE:NetBeans 7.2
  • JDK:7 update 7

1 个答案:

答案 0 :(得分:1)

出现问题是因为remove和find方法都将TesttablePK类型与@PathParam结合使用,但Jersey无法找到将字符串从url转换为此类对象的方法。这可以通过修改TesttablePK类型来解决。你有两个选择:

  • 添加一个接受单个String参数的构造函数。
  • 或添加名为valueOf的静态方法或接受a的fromString 单个字符串参数

因此,您需要决定如何将复合键表示为字符串并将此类字符串转换为TesttablePK类型。
