从无状态 EJB Bean 处理异常和重定向页面
Handle Exception and Redirect Page From Stateless EJB Bean
我有一个 JSF 项目。在我的项目中，我使用 Stateless EJB bean 将数据库与数据源连接起来。我通过考虑异常的错误代码来处理数据库 SQLExceptions。当我收到 20999 错误代码时，我需要使会话无效并将页面重定向到 EJB bean 中的登录页面。
@Stateless
public class DB implements DBRemote {
@Resource(mappedName = "resource")
private DataSource ds;
@Override
public DBResult run(String query, String[] strParams) {
Connection connection = ds.getConnection();
CallableStatement callableStatement = connection.prepareCall(sql);
callableStatement.execute();
} catch (SQLException ex) {
dbResult.setIsSuccess(false);
switch (ex.getErrorCode()) {
case 17008:
dbResult.setErrorMessage("Timeout");
break;
case 20999:
dbResult.setErrorMessage("Session Not Found");
dbResult.close();
//THROW EXCEPTION OR NAVIGATE TO LOGIN PAGE
/*
FacesContext context = FacesContext.getCurrentInstance();
NavigationHandler nav = context.getApplication().getNavigationHandler();
nav.handleNavigation(context, null, "/login?faces-redirect=true");
*/
default:
dbResult.setErrorMessage("System Error");
break;
}
Logger.getLogger(DB.class.getName()).log(Level.SEVERE, null, ex);
dbResult.close();
}
return dbResult;
}
}
我尝试使用 NavigationHandler 重定向 case 20999 内的页面，但在发生异常时它没有导航页面。
FacesContext context = FacesContext.getCurrentInstance();
NavigationHandler nav = context.getApplication().getNavigationHandler();
nav.handleNavigation(context, null, "/login?faces-redirect=true");
异常：

我也有一个自定义异常处理程序 class，例如 here。有没有办法处理其中的错误？（也许是自定义异常！？）
提前致谢。
异常似乎不是 SQLException。它似乎是 NullPointerException 在您的 VisitManager.getVisits() 方法中。
EJB 方法中未捕获的运行时异常将导致当前事务自动回滚。这就是为什么您会看到 NullPointerException 包裹在 EJBTransactionRolledbackException 中。
尝试修复 NullPointerException，看看是否能解决您的问题。
首先，@BalusC 将此问题标记为重复：
而且我没有破锁。
其次，我就是这样解决问题的；
1.我定义两个 class 为@BalusC
@ApplicationException(rollback=true)
public abstract class ServiceException extends RuntimeException {}
public class SessionTimeOutException extends ServiceException {}
2。我抛出异常
@Override
public DBResult run(String query, String[] strParams) {
Connection connection = ds.getConnection();
CallableStatement callableStatement = connection.prepareCall(sql);
callableStatement.execute();
} catch (SQLException ex) {
dbResult.setIsSuccess(false);
switch (ex.getErrorCode()) {
case 17008:
dbResult.setErrorMessage("Timeout");
break;
case 20999:
dbResult.setErrorMessage("Session Not Found");
dbResult.close();
throw new SessionTimeOutException();
default:
dbResult.setErrorMessage("System Error");
break;
}
Logger.getLogger(DB.class.getName()).log(Level.SEVERE, null, ex);
dbResult.close();
}
return dbResult;
}
3。我使用 Primefaces ExceptionHandler
处理异常
尽管我已经有了一个自定义异常处理程序 class，但我已经检查了源代码，这似乎是未来更好的方式。
<p:remoteCommand name="closeSession" actionListener="#{loginBean.logout()}" />
<p:ajaxExceptionHandler type="com.extranet.exception.SessionTimeOutException"
onexception="closeSession();" />
最后，我建议阅读 primefaces 文档。
我有一个 JSF 项目。在我的项目中，我使用 Stateless EJB bean 将数据库与数据源连接起来。我通过考虑异常的错误代码来处理数据库 SQLExceptions。当我收到 20999 错误代码时，我需要使会话无效并将页面重定向到 EJB bean 中的登录页面。
@Stateless
public class DB implements DBRemote {
@Resource(mappedName = "resource")
private DataSource ds;
@Override
public DBResult run(String query, String[] strParams) {
Connection connection = ds.getConnection();
CallableStatement callableStatement = connection.prepareCall(sql);
callableStatement.execute();
} catch (SQLException ex) {
dbResult.setIsSuccess(false);
switch (ex.getErrorCode()) {
case 17008:
dbResult.setErrorMessage("Timeout");
break;
case 20999:
dbResult.setErrorMessage("Session Not Found");
dbResult.close();
//THROW EXCEPTION OR NAVIGATE TO LOGIN PAGE
/*
FacesContext context = FacesContext.getCurrentInstance();
NavigationHandler nav = context.getApplication().getNavigationHandler();
nav.handleNavigation(context, null, "/login?faces-redirect=true");
*/
default:
dbResult.setErrorMessage("System Error");
break;
}
Logger.getLogger(DB.class.getName()).log(Level.SEVERE, null, ex);
dbResult.close();
}
return dbResult;
}
}
我尝试使用 NavigationHandler 重定向 case 20999 内的页面，但在发生异常时它没有导航页面。
FacesContext context = FacesContext.getCurrentInstance();
NavigationHandler nav = context.getApplication().getNavigationHandler();
nav.handleNavigation(context, null, "/login?faces-redirect=true");
异常：

我也有一个自定义异常处理程序 class，例如 here。有没有办法处理其中的错误？（也许是自定义异常！？）
提前致谢。
异常似乎不是 SQLException。它似乎是 NullPointerException 在您的 VisitManager.getVisits() 方法中。
EJB 方法中未捕获的运行时异常将导致当前事务自动回滚。这就是为什么您会看到 NullPointerException 包裹在 EJBTransactionRolledbackException 中。
尝试修复 NullPointerException，看看是否能解决您的问题。
首先，@BalusC 将此问题标记为重复：
而且我没有破锁。
其次，我就是这样解决问题的；
1.我定义两个 class 为@BalusC
@ApplicationException(rollback=true)
public abstract class ServiceException extends RuntimeException {}
public class SessionTimeOutException extends ServiceException {}
2。我抛出异常
@Override
public DBResult run(String query, String[] strParams) {
Connection connection = ds.getConnection();
CallableStatement callableStatement = connection.prepareCall(sql);
callableStatement.execute();
} catch (SQLException ex) {
dbResult.setIsSuccess(false);
switch (ex.getErrorCode()) {
case 17008:
dbResult.setErrorMessage("Timeout");
break;
case 20999:
dbResult.setErrorMessage("Session Not Found");
dbResult.close();
throw new SessionTimeOutException();
default:
dbResult.setErrorMessage("System Error");
break;
}
Logger.getLogger(DB.class.getName()).log(Level.SEVERE, null, ex);
dbResult.close();
}
return dbResult;
}
3。我使用 Primefaces ExceptionHandler
处理异常尽管我已经有了一个自定义异常处理程序 class，但我已经检查了源代码，这似乎是未来更好的方式。
<p:remoteCommand name="closeSession" actionListener="#{loginBean.logout()}" />
<p:ajaxExceptionHandler type="com.extranet.exception.SessionTimeOutException"
onexception="closeSession();" />
最后，我建议阅读 primefaces 文档。
