Some of the best practices in handling exceptions in spring:


  1.  Use Checked Exceptions if there is a reasonable expectation that the client can handle and recover from the exception otherwise use Unchecked (you will mostly use unchecked).
  2.  Use the @ExceptionHandler annotation on a method to handle exceptions generated from @RequestMapping methods.
  3.   Create custom exceptions and throw those instead (you can pass the actual exception as the cause ie throw new MyCustomException("my message", e)).   
  4. Your @ExceptionHandler method can decide what view to return to the user, or you can configure a custom error page in your web.xml
