I just added a zip file to JIRA which contains some Spring FactoryBeans
making it quite simple to configure Mina Acceptors and Connectors using
Spring. Please have a look at it and let me know what you think. To
build it you will have to add some dependencies to project.xml:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl104-over-slf4j</artifactId>
<version>1.0-beta9</version>
<url>http://www.slf4j.org/</url>
</dependency>
<dependency>
<groupId>springframework</groupId>
<artifactId>spring-core</artifactId>
<version>1.2.5</version>
<url>http://www.springframework.org/</url>
</dependency>
<dependency>
<groupId>springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>1.2.5</version>
<url>http://www.springframework.org/</url>
</dependency>
To run the tests Easymock is required:
<dependency>
<groupId>easymock</groupId>
<artifactId>easymock</artifactId>
<version>1.2_Java1.3</version>
<url>http://www.easymock.org/</url>
</dependency>
<dependency>
<groupId>easymock</groupId>
<artifactId>easymockclassextension</artifactId>
<version>1.2</version>
<url>http://www.easymock.org/</url>
</dependency>
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib-nodep</artifactId>
<version>2.1</version>
<url>http://cglib.sourceforge.net/</url>
</dependency>
Unfortunately version 1.2 of easymockclassextension doesn't appear to be
in the maven repository. I had to download it from
http://www.easymock.org and install it into my local repository. I hope
that's ok.
I was thinking about writing something on how to build, test and use
these FactoryBeans on the WIKI. Would MinaSpringIntegration be a good
name for such a WIKI page?
