想试一下注册的API，报如上错误

你将PUSH到服务器的war放到目录后，手动解压一下，然后重启服务器看看。

• 提问者 passerbyYSQ #1

  我在webapps-italker目录下将ROOT.war解压后，并将ROOT.war暂时移到其他地方，然后重启tomcat。连index.jsp也访问不了，访问直接404。

• 提问者 passerbyYSQ #2

  老师，我有点奇怪，这是上面报错日志中的一个路径，为什么路径中“ROOT.war”的后面多了个星号“*”。
  【报错日志中的一个路径】： file:/opt/tomcat/apache-tomcat-9.0.31/webapps-italker/ROOT.war*/WEB-INF/classes/net/qiujuer/web/italker/push/service/ is not supported. Package scanning deployment is not supported for such URIs.

  你解压后的目录截图我看看，有些时候是目录错误了。

出现了另外的异常，空指针异常，【在本地测试正常，没问题】

服务器上的hibernate配置文件

• 提问者 passerbyYSQ #1

  我把方言改为org.hibernate.dialect.MySQL8Dialect，重新试了一下，也是一样

• 提问者 passerbyYSQ #2

  【mysql8的驱动jar包】我突然发现服务器上的war包里面的mysql驱动jar包还是5点几。 |||  于是我想通过gradle依赖下载最新的驱动jar包，但是idea下载不了。我从其他途径下载了mysql-connector-java-8.0.19，传输到服务器上，然后拷贝到对应的webapps-italker/ROOT/WEB-INF/lib/下面。  |||  重启tomcat后，访问index.jsp直接404。 ||| 心态炸裂。老师，我能不能在qq发你远程登录的账户和密码，您能不能帮我上去看一看？？？ o(╥﹏╥)o

  你在talker中解压的时候，放到ROOT目录下。也就是使用ROOT包裹起来。

• 提问者 passerbyYSQ 回复 Qiujuer #2

  老师，按照您说的，我改正之后又重新用DHC访问注册的API。又报空指针错误。报错截图和服务器上的hibernate配置文件的截图，我发在上面的回帖。   但是我在本地测试没问题，本地的mysql数据库是5.7，服务器上的mysql是8。

  方便私聊发我ip之类的么。我帮你看看。
