本文主要供自己使用,不喜勿喷。错误的地方请留下您的宝贵建议,万分感激!
1024程序员节让我遇到了这个错误,快要把我气炸了,怎么整都不好使!
上面这个图是网上截取的,我的跟这个差不多,不是在hashmap中打的断点,我就是在自己的类中打了个断点!
(这种情况在非Debug模式下是不会出现的)
然后网上百度有很多种说法,大致就是下面这个意思:
说法一:
编译器设置问题
window->preferences->java->compiler
classfile Generation区域中确认已经勾选了All line number attributes to generated class files
如果已经勾选,重新apply以下;或者从项目层次进行设定,项目属性->java compiler
window->preferences->java->compiler
classfile Generation区域中确认已经勾选了All line number attributes to generated class files
如果已经勾选,重新apply以下;或者从项目层次进行设定,项目属性->java compiler
步骤一所说的这种情况在我的eclipse里就是默认设置,所以对我来说是没有用的
说法二:
出现这个问题的根本原因是:eclipse中的project和deploy到web container中的project对应不起来。
所以,可以先从web container中先把项目删除,再从eclipse中部署
所以,可以先从web container中先把项目删除,再从eclipse中部署
这种情况我也尝试了,删除项目甚至把服务器实例都删除了重新创建,还是会报相同的错误
说法三:
有的说把工程下的.setting文件夹删除后重新加载项目,我试了也没有用
所以现在还是有点不明白,因为我的工程在报错之后点击确定按钮还是可以跑的,所以就先做项目了,如果哪位大神知道的话,请留下您的宝贵意见!
