异常备忘:java.lang.UnsupportedClassVersionError: Bad version number in .class file
今天在导入一个工程时,编译并打包到Tomcat后,发现出现java.lang.UnsupportedClassVersionError: Bad version number in .class file异常,检查了一下我的myEclipse,发现不知道啥时候不小心将编译器改成JDK6.0了,那个工程是从同事的机上拷贝过来的,用的编译器是JDK5.0,试了一下,果然是这个问题引起。
那次在Linux上部署工程时也出现过因为版本不同引起的问题,那时我们用的IDE的编译器是JDK5.0,而那台Linux装的是JDK6.0,部署后发现很多功能都出错,看来有些东西还是得注意一下啊。
附,在myEclipse中改变编译器的方法:Project->roperties->Java Compiler->Configure Workspace Setting,在弹出的页面中可以进行设置。 |
