所以我在这里 - 运行着一个使用Spring Roo的Spring应用程序。
我习惯将我的控制器切割成方面,因此我的主控制器看起来像这样:
@Controller
@RequestMapping("/apples")
@SessionAttributes(types = {Apple.class})
public class AppleController {
}
还有其他方面可以扩展其功能,例如:
privileged aspect AppleController_Basics {
@RequestMapping(value = "/allApples", produces = "text/html", method=RequestMethod.GET)
public String AppleController.allApples(Model model) {
...
return "apples/list";
}
}
现在,当我尝试在方面内使用Java 8 stream API时:
apples.stream().filter(a -> a.isSweet()).collect(Collectors.toList());
我遇到了以下异常:
org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.BootstrapMethodError: java.lang.NoSuchMethodError: com.apple.web.AppleController.lambda$0(Lcom/apple/model/Apple;)Z
当我使用流API处理除了苹果本身之外的其他实体时,我会得到一个略微不同的异常:
org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.BootstrapMethodError: java.lang.IllegalAccessError: tried to access method com.apple.web.AppleController.lambda$0(Lcom/apple/security/AppleEater;)Z from class com.apple.web.aspects.AppleController_Basics
使用forEach时,我遇到了OutOfMemoryError::
apples.forEach(System.out::println);
org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.OutOfMemoryError: Java heap space
当我在主类中使用这些表达式时,一切都正常。
插件看起来像这样:

我尝试了不同的方法来更改我的AspectJ插件配置以使其正常工作,但都没有成功。我非常困惑,希望能得到任何提示或帮助,请不要讨厌我 <3
