Logger injection to JdbcAdapter subclass does not work
------------------------------------------------------
Key: CAY-1655
URL: https://issues.apache.org/jira/browse/CAY-1655
Project: Cayenne
Issue Type: Bug
Components: Core Library
Affects Versions: 3.1M3
Environment: Windows 7, MS Access, JdbcOdbc driver
Reporter: Wernke zur Borg
I created a custom subclass of JdbcAdapter for some special handling with MS
Access. It is instantiated by a custom DbAdapterFactory subclass, which is
configured as:
Module m = new Module() {
public void configure(Binder binder) {
binder.bind(DbAdapterFactory.class).to(MyCustomDbAdapterFactory.class);
}
};
Now the application runs into a NullPointerException in
org.apache.cayenne.access.jdbc.SelectAction.performAction() where it says:
adapter.getJdbcEventLogger()... (line 171)
This means that the injection of the JdbcEventLogger "logger" in my superclass
JdbcAdapter has not taken place. It might be important that also SelectAction
has been subclassed with a custom SelectAction.
The problem does not occur when I comment the binder.bind(...) line out.
Workaround: Instantiate a CommonsJdbcEventLogger in the custom JdbcAdapter and
assign it to the logger (it is protected). But this logger is not aware of the
log4j log level.
