【问题描述】：
我一直在尝试让一个示例 @Configuration 构建工作（在 groovy 中），所以我可以使用 spring 容器触发依赖注入，但我得到的只是关于我似乎无法修复的 -javaagent 的错误
我有一个这样的 beanConfig 类
@Configuration
@EnableSpringConfigured // should turn on AnnotationBeanConfigurerAspect
@EnableLoadTimeWeaving (aspectjWeaving=AspectJWeaving.ENABLED) // switch on for this context
class BeanConfig {
然后我将调用一个示例类 new 并尝试在 spring 容器之外进行注入，其中 diSource bean 在上述配置类中声明
` @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，我调用它来尝试触发注入
` ... 静态无效主要（字符串[]参数）{ AnnotationConfigApplicationContext ctx = new 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
dependencies {
compile 'org.codehaus.groovy:groovy-all:2.1.7'
compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
testCompile group: 'junit', name: 'junit', version: '4.+'
compile "org.springframework:spring-core:${spring_version}"
compile "org.springframework:spring-beans:${spring_version}"
compile "org.springframework:spring-context:${spring_version}"
compile "org.springframework:spring-aspects:${spring_version}"
compile "org.springframework:spring-aop:${spring_version}"
compile "org.springframework:spring-instrument:${spring_version}"
compile "org.aspectj:aspectjrt:1.6.10"
compile "org.aspectj:aspectjweaver:1.6.10"
compile "cglib:cglib:2.2"
}
在我拥有的 vm args 的 eclipse 项目运行时
-javaagent:C:/Users/802518659/aspectjweaver-1.6.10.jar
并尝试过使用 spring-instrument-3.1.4.jar 并遇到同样的问题。
当我运行项目时，我得到了这个错误

`
这告诉我我的应用程序无法检测 java 类加载器 - 尽管我使用 -javaagent:spring-instrument-xxx 或 aspectjweaver.jar 启动它 - 两者都失败了
那么我做错了什么 - 这真的开始困扰我 - 我可以在上下文中进行普通注入（没有 LTW），但真的想在容器外进行这种注入工作
我做错了什么
