原因
因为在使用Maven打包的时候导致某些包的重复引用,以至于打包之后的META-INF
的目录下多出了一些*.SF,.DSA,.RSA文件所致。
例如:
./META-INF$ ls
BCKEY.DSA BCKEY.SF DEPENDENCIES LICENSE MANIFEST.MF NOTICE io.netty.versions.properties maven native services spring.provides versions
包含BCKEY.DSA BCKEY.SF
。
解决方法
删除jar包中的意外文件
zip -d your.jar 'META-INF/*.SF' 'META-INF/*.RSA' 'META-INF/*.DSA'
mvn 过滤文件
我们可以在Plugin中加入以下配置:
<configuration>
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
</configuration>
诊断mvn package dependecy方法
诊断package重复使用mvn dependency:tree -Dverbose
$ mvn dependecy:tree -Dverbose
