错误

在tomcat中运行是没有问题的，可是在weblogic中是不能够运行的，weblogic中的jdk客户要求是1.6的。

如果更换版本jedis2.9.0是没有问题的。

报错如下:

探索

进入jedis的MANIFEST.MF文件，发现



Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.7))"

可以看到加载的版本，需要的jdk版本是1.7的。

总结

前提：在war包的lib目录下确实有相关的jar包，只是没有加载到。

因为java.lang.NoClassDefFoundError是在运行的时候没有加载到jar包，而不是在编译的时候有问题，而上面的文件中说明了，加载的过滤条件，必须要1.7以上的，通过查看2.9.0要求的版本是1.6的。得知真正的原因就是这里。
