Eclipse RCP 中的 Spring 加载时间编织
我正在尝试在 Eclipse RCP 应用程序中使用 Spring 的加载时编织功能和 @Configurable
。我正在使用 Spring OSGI Extender 加载我的应用程序上下文。
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="...">
<context:annotation-config />
<context:load-time-weaver />
<context:spring-configured />
</beans>
应用程序创建得很好,但是当我尝试注释一个不由 Spring 管理的类(在我的例子中是 SWT 对话框)时,出现以下异常:
Exception in thread "SpringOsgiExtenderThread-2" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [org.springframework.osgi.util.BundleDelegatingClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method.

我尝试在 VM 设置中使用 -javaagent:... 启动应用程序,无济于事。
有人有这方面的经验吗?
多谢!
I'm trying to use Spring's load-time-weaving capabilities with @Configurable
within an Eclipse RCP application. I am using Spring OSGI Extender to load my application context.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="...">
<context:annotation-config />
<context:load-time-weaver />
<context:spring-configured />
</beans>
The application gets created all right, but when I try to annotate a class not managed by Spring (in my case an SWT Dialog) I get the following exception:
Exception in thread "SpringOsgiExtenderThread-2" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [org.springframework.osgi.util.BundleDelegatingClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method.

I have tried starting the Application with -javaagent:... in the VM settings, to no avail.
Does anyone have experience with this?
Thanks a lot!
