[WangBuEr]

在eclipse里面运行正常,打成jar报运行则报此问题

[lihengming]

用的什么版本的druid starter？

[WangBuEr]

1.1.3 . spring boot 用的是1.5.6

[lihengming]

用1.5.4试试，可能新版本不兼容。

[WangBuEr]

问题解决了,spring boot 1.5.6版本也没有问题,经排查是maven在下载jar包的时候有问题,打开maven下载的jar报中的class显示invalid loc header (bad signature)错误,删除重新下载jar之后解决了!!!!!!!!!!!
