java.lang.VerifyError: class net.sf.cglib.core.DebuggingClassWriter

Question

Bir öğreticiden kaynaklanan oldukça basit bir Hazırda kodun prototipini hazırlamaya çalışıyorum ve bir hata alıyorum cglib2'de tam anlamıyorum (tam yığın izi bu gönderinin sonundadır). Muhtemelen basit ana() ve fasulye XML (aşağı) başına 'productBoProxy' oluşturmaya çalışıyorum.

Cglib'in birçok farklı sürümünü boşuna kullanıyorum. Bunu çözmek için doğru yolu bulmama yardımcı olabilecek herkese çok minnettarım.

App.java:

ApplicationContext appContext 
    = new ClassPathXmlApplicationContext("resources/config/BeanLocations.xml"); 
... 
productBo = (ProductBo) appContext.getBean("productBoProxy"); 
productBo.save(product, 100); 

Product.xml:

... 
<!-- This is a proxy factory bean; see App.java --> 
<bean id="productBoProxy" 
     class="org.springframework.aop.framework.ProxyFactoryBean"> 
    <property name="target" ref="productBo" /> 
    <property name="interceptorNames"> 
    <list> 
     <value>transactionInterceptor</value> 
    </list> 
    </property> 
</bean> 
... 

Yığın izleme:

Sen CGLIB ve ASM uyuşmazlık sürümleri var. Stacktrace, "net.sf.cglib.core.DebuggingClassWriter, son yöntem ziyaretini geçersiz kılar", diğer bir deyişle org.objectweb.asm.ClassWriter 'i genişleten, son yöntem ziyaretini geçersiz kılmaya çalışan net.sf.cglib.core.DebuggingClassWriter komutunu anlatır. başarısız olur.

Örneğin maven dependendy for cglib 2.2.2 asm 3.3.1 çeker, bu nedenle denemenin bir kombinasyonudur.
