the @Configurable annotation is the cure, basically, its till aspect/aspectJ to detect if any instantiation of beans marked as Configurable; and put into spring container if yes.
and it’s only put into spring container after the bean is manually instantiated. So autowired stuff won’t work in this manually instantiated bean still.
And in order to have spring beans loaded/injected into aspects
btw, I dont like spring docs now. it becomes so bulky !
8.8.1 Using AspectJ to dependency inject domain objects with Spring
8.8.3 Configuring AspectJ aspects using Spring IoC
Just configure the VM arguments to overwrite the log4j file path
it’s taken as Object by JDK.
to create new instance of the object using Reflection;
To keep the line number of the class:
<appender name="ASYNC" class="org.apache.log4j.AsyncAppender">
<param name="BufferSize" value="256"/>
<param name="LocationInfo" value="true"/>
The addAppender method adds an appender to a given logger. Each enabled logging request for a given logger will be forwarded to all the appenders in that logger as well as the appenders higher in the hierarchy. In other words, appenders are inherited additively from the logger hierarchy. For example, if a console appender is added to the root logger, then all enabled logging requests will at least print on the console. If in addition a file appender is added to a logger, say C, then enabled logging requests for C and C's children will print on a file and on the console. It is possible to override this default behavior so that appender accumulation is no longer additive by setting the additivity flag to false.
The rules governing appender additivity are summarized below.
The output of a log statement of logger C will go to all the appenders in C and its ancestors. This is the meaning of the term "appender additivity".
However, if an ancestor of logger C, say P, has the additivity flag set to false, then C's output will be directed to all the appenders in C and its ancestors upto and including P but not the appenders in any of the ancestors of P.
Loggers have their additivity flag set to true by default.
I might be late to realize this:
I re-encountered this again, in tedious ways.
