[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-3842) Additional annotations support for "Generate Hibernate/JPA annotations"

[Vitali Yemialyanchyk (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-3842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12460220#action_12460220 ] 

Vitali Yemialyanchyk commented on JBIDE-3842:
---------------------------------------------

3) here I'm hesitate  - we need to discuss this: 
is @GeneratedValue @Id annotations enough to create db column which doesn't accept null value?

4) my argument here - 255 is to long value.
the user case:
a) to create DB structure I create several java classes
b) then I use "Generate Hibernate/JPA annotations" to anotate all these classes;
c) then I want to create DB tables from annotated classes
if I get all columns length 255 it is BIG ENOUGH to store almost all user input,
but it is TOO BIG for all data (login, first name, last name, password, etc)
so the default case can't satisfy this, so I should add
@Column(length = N) for login (first name, last name, password, etc) column by the hands - 
we can generate this to avoid such manual updates.
