Could not initialize class io.jsonwebtoken.impl.DefaultJwtBuilder
java.lang.NoClassDefFoundError: Could not initialize class io.jsonwebtoken.impl.DefaultJwtBuilder
	at io.jsonwebtoken.Jwts.builder(Jwts.java:116) ~[jjwt-0.7.0.jar:0.7.0]

原因,因为jackson-databindb版本冲突，直接去掉了依赖

jwt必须依赖Jackson所以报错了

出错时候的配置
