Question

我一直试图让一个示例@Configuration构建工作（在groovy中）所以我可以触发依赖注入弹出容器，但我得到的是关于-javaagent的错误，我似乎无法修复

我有像这样的beanConfig类

@Configuration @EnableSpringConfigured // should turn on AnnotationBeanConfigurerAspect @EnableLoadTimeWeaving (aspectjWeaving=AspectJWeaving.ENABLED) // switch on for this context class BeanConfig {

然后一个示例类我将调用new并尝试将spring注入到Spring容器中，其中diSource bean在上面的配置类中声明

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

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

`

在我的sampler类中，我调用它来尝试触发注入

` ... static void main（String [] args）{ 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等继承我的gradle depdency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项目运行时中 -javaagent:C:/Users/802518659/aspectjweaver-1.6.10.jar

并尝试使用spring-instrument-3.1.4.jar并遇到同样的问题。

当我运行项目时，我收到此错误

告诉我，我的应用程序无法检测java类加载器 - 尽管我使用-javaagent启动它：spring-instrument-xxx或aspectjweaver.jar - 都失败

所以我做错了什么 - 这真的开始困扰我 - 我可以在上下文中进行普通注射工作（没有LTW）但是真的想让这个注射器在容器外工作

我做错了什么

花了一些时间，但想出了它出错的地方

在春季论坛的另一篇文章中更正了 http://forum.spring.io/forum/spring-projects/container/724426-cant-get-aspectj-load-time-weaving-to-work

我也在这里给我的博客添加了一个更长的音符
