为什么我不能让弹簧加载时间进行编织工作

我一直在尝试使@Configuration构建示例工作(以常规方式),因此我可以使用Spring容器触发依赖项注入,但是我所得到的只是关于-javaagent的错误,我似乎无法修复

我有一个像这样的beanConfig类

    @组态
    @EnableSpringConfigured //应该打开AnnotationBeanConfigurerAspect
    @EnableLoadTimeWeaving(aspectjWeaving = AspectJWeaving.ENABLED)//为此上下文打开
    BeanConfig类{

然后是一个示例类,我将调用new并尝试将注入替换为spring容器,在上述配置类中声明了diSource bean

`
    @Configurable(autowire = Autowire.BY_TYPE,dependencyCheck = true)
    类ExtDI {
    @Autowired DISource diSource

def say () {
    println "ExtDI : diSource set as " + diSource.name
}
}

在我的采样器类中,我称其为尝试触发进样

`
    …
    静态void main(String [] args){
        AnnotationConfigApplicationContext ctx =新的AnnotationConfigApplicationContext(/BeanConfig.class/)
        ctx.scan(“ com.softwood”)
        ctx.refresh()
    ….

    //trigger LTW injection
    ExtDI ext = new ExtDI()
    ext.say()

在类路径上,我有Aspectjeaver-1.6.10.jar,aspectjrt-1.6.10.jar,spring-xxx-3.1.4.jars等
这是我的gradle依赖列表

    依赖项{
    编译’org.codehaus.groovy：groovy-all：2.1.7′
    编译组：“ commons-collections”,名称：“ commons-collections”,版本：“ 3.2”
    testCompile组：’junit’,名称：’junit’,版本：’4. ‘
    编译“ org.springframework：spring-core：${spring_version}”
    编译“ org.springframework：spring-beans：${spring_version}”
    编译“ org.springframework：spring-context：${spring_version}”
    编译“ org.springframework：spring-aspects：${spring_version}”
    编译“ org.springframework：spring-aop：${spring_version}”
    编译“ org.springframework：spring-instrument：${spring_version}”
    编译“ org.aspectj：aspectjrt：1.6.10”
    编译“ org.aspectj：aspectjweaver：1.6.10”
    编译“ cglib：cglib：2.2”
    }

在Eclipse项目运行时中我有的vm args

-javaagent：C：/Users/802518659/aspectjweaver-1.6.10.jar

并尝试与spring-instrument-3.1.4.jar相同,并且有相同的问题.

当我运行项目时,出现此错误

这告诉我我的应用程序无法检测Java类加载器-尽管事实上我使用-javaagent：spring-instrument-xxx或Aspectjweaver.jar启动它-均失败

所以我在做什么错-这真的开始困扰我-我可以在上下文中进行普通注入工作(没有LTW),但我真的想在容器外部进行这种注入工作

我究竟做错了什么

解决方法:

花了一些时间,但找出了哪里出了问题

在春季论坛上的另一篇文章中更正,请参见

我也在这里在我的博客中添加了更长的注释
