我工作的接缝,并试图通过使用煤层@In属性要求非空值
@Name("myBeanClass")
@Scope(ScopeType.CONVERSATION)
public class MyBeanClass {
start();
}
注入一个接缝部件,并试图通过使用下面的代码从另一个类使用上述start()
@In(create = true, required = false, value = "myBeanClass")
protected MyBeanClass myBeanClass
public Class TestClass {
public void start() {
myBeanClass.start();
}
}
我甚至在MyBeanClass
变化范围类型,雪村等尝试,它仍然是给我同样的eception

而且也是我能够从同一类注入等类,我是失败只在注射myBeanClass
任何一个可以建议如果我错过了任何东西的情况下?
我确信豆的名称和变量名是相同的
WOOW。 ü拯救我的生命! – 2015-11-09 11:24:31
