在配置S2SH时由于jar包冲突引起的异常

                                  在配置S2SH时由于jar包冲突引起的异常

 

1.  由于Spring中的“asm-2.2.3.jar”和Hibernate中的“asm.jar”包冲突。
     解决办法是移除Spring2.0 AOP Libraries中的“asm-2.2.3.jar”即可。

        （注：如果删包后还存在该异常，那就应该检查代码，例如MyEclipse自动生成的DAO是否实现了你自己写的IDAO接口，因为如果没有实现的话，在spring中将service层引用的IDAO接口进行DAO实体的注入那肯定是错误的）

 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'UserAction' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Cannot resolve reference to bean 'IUserService' while setting bean property 'iuSer'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'IUserService' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Cannot resolve reference to bean 'TUserDAO' while setting bean property 'iuerDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'TUserDAO' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String

 

2.  解决的方法：将lib目录下的： hibernate-annotations.jar 和 hibernate-commons-annotations.jar删除后重新部署可。

错误原因：如下
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [beans.xml]: Invocation of init method failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.hibernate.cfg.AnnotationConfiguration]: Constructor threw exception; nested exception is java.lang.ClassCastException: org.hibernate.annotations.common.reflection.java.JavaReflectionManager cannot be cast to org.hibernate.annotations.common.reflection.MetadataProviderInjector
