Question

Web.xml

<error-page> 
     <exception-type>org.test.AuthorisationException</exception-type> 
     <location>/WEB-INF/jsp/error/unauthorised.jsp</location> 
</error-page> 

AuthorisationException.java

public class AuthorisationException extends Exception { 

    public AuthorisationException(String message) { 
     super(message); 
    } 

    public AuthorisationException(Throwable cause) { 
     super(cause); 
     // TODO Auto-generated constructor stub 
    } 

    public AuthorisationException(String message, Throwable cause) { 
     super(message, cause); 
     // TODO Auto-generated constructor stub 
    } 
} 

servlet.xml

<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">

org.test.AuthorisationException: Access Denied! 

Ich denke, es funktioniert nicht, da die Ausnahme auf der obersten Ebene org.springframework.web.util.NestedServletException nicht mit der Ausnahme Zuordnung übereinstimmt und die Seite nicht angezeigt wird. Wie kann ich damit umgehen?

Answer 1

Der Code behandelt nur die benutzerdefinierte Ausnahme - AuthorizationException. Möchten Sie Ausnahmen behandeln? Dann müssen Sie java.lang.Exception einer Fehlerseite zuordnen.
