java - calling spring controller from web.xml (exception-type) -


i need know if way there call spring controller web.xml following location:

<error-page>     <exception-type>org.demo.exceptions.invalidsessionexception</exception-type>     <location>/login.jsp</location> </error-page>

i have created custom exception class named invalisessionexception, typically call jsp page <location> tag, need call login controller such auth/login i.e. <location>/auth/login</location>.

is there way achieve ?

invalisessionexception.java

public class invalidsessionexception extends nullpointerexception  {     private static final long serialversionuid = 1l;  public string getmessage() {     return "no user logged in."; }  public int getexceptiontype() {     return -1; } }

the preferred way add "global exception handler" within in spring context, instead of trying re-enter spring context web.xml.

you can achieve configuring org.springframework.web.servlet.handler.simplemappingexceptionresolver bean in context. set exceptionmappings property list of exceptions resolver should act on, , each exception, mention view should shown user.

this keeps design clean , maintainable.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
