unable to install breakpoint in com... $ $FastClassBySpringCGLIB$ $12fabbfc due to missing line numb

问题：unable to install breakpoint in com... $ $FastClassBySpringCGLIB$ $12fabbfc due to missing line number attributes.
Modify compiler options to generate line number attributes.
reason:Absent line number information.

解决：eclipse -- 右上角debug -- Breakpoints -- 点击双叉号（删除所有断点）

注：出错原因是删除了或修改了带有断点的代码，eclipse提示你找不到断点，删除断点就好了。
