如何强制Hibernate 3.3或3.5使用CGLib而不是Javassist？

Question

Is it still possible to force Hibernate 3.3 or 3.5 to use CGLib instead of Javassist? In my properties file, I set

hibernate.bytecode.provider = cglib

But this doesn't seem to do it. Any thoughts?

Answer 1

It seems some people didn't read my answer correctly so I'll rephrase: your hibernate.properties looks correct, the property is well defined, it should work. So, sorry for the question but is CGlib on the classpath?

Update: Just tested and it works for me. Here is the output I get at initialization time:

15 [main] INFO org.hibernate.cfg.Environment - Hibernate 3.3.0.SP1
18 [main] INFO org.hibernate.cfg.Environment - loaded properties from resource hibernate.properties: {hibernate.bytecode.use_reflection_optimizer=false, hibernate.bytecode.provider=cglib}
20 [main] INFO org.hibernate.cfg.Environment - Bytecode provider name : cglib

PS: Note that CGLIB support has been deprecated recently (this doesn't mean you won't be able to use CGLIB but the integration it not maintained anymore).

Answer 2

Yeah, also put

hibernate.properties 

into some source folder and remember to have the hibermate-cglib-repack in dependencies:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-cglib-repack</artifactId>
    <version>2.1_3</version>
</dependency> 

Answer 3

Remember that CGLIB library is not developed for about 4 years. You should do everything however to make your code working with Javassist, which is still actively maintained.
