[Springframework-developer] polishing and new features

[<jue...@we...>]

I've just committed extensive polishing and several new features for the =
transaction package etc, i.e. all my stuff from the last few days:

- support for Hibernate flush modes on HibernateTemplate and =
HibernateInterceptor;

- support for read-only transactions via a new =
TransactionDefinition.readOnly property: DataSourceTransactionManager =
and HibernateTransactionManager actually support this via =
Connection.setReadOnly and Hibernate's FlushMode.NEVER;

- fixed rollback exception handling: if the rollback operation itself =
throws an exception, the application exception's stacktrace gets logged =
now, and the transaction system exception thrown;

- reworked TransactionAttributeSourceEditor: supports "readOnly" =
keyword, and the other keywords in any order now (like =
"+RemoteException,readOnly,ISOLATION_READ_COMMITTERD,PROPAGATION_REQUIRED=
");

- reworked MapTransactionAttributeSource: can also be used as bean, to =
specify a "methodMap" method/attribute map that allows for bean =
references to fully configurable DefaultTransactionAttribute instances;

- application context includes via XML entities: the new =
ResourceBaseEntityResolver resolves such entities relative to the =
resource base of the application context now, allowing for splitting =
context definitions into multiple files;

- DAO base classes: the new JdbcDaoSupport, HibernateDaoSupport, and =
JdoDaoSupport classes in respective support packages can serve as =
convenient base classes for DAOs that use the templates;

- HandlerInterceptor.postHandle: the web interceptor framework supports =
postHandle now in addition to preHandle, allowing e.g. for binding user =
contexts from a session attribute to a ThreadLocal in preHandle and =
removing it again in postHandle.

Anyone who can find the time, please try the current CVS contents, and =
review the changes if you like. That's it for 0.9.1 from me.
