Can you please help on this.
回答1:
Try to upgrade the version of TomCat. This is fixed in:
- trunk for 9.0.0.M18 onwards
- 8.5.x for 8.5.12 onwards
- 8.0.x for 8.0.42 onwards
- 7.0.x for 7.0.76 onwards
The reason it doesn't work is because you use modularized (with module-info.class file) dependencies with old TomCat versions. TomCat (bcel library) tries to scan class files attempting to find annotations like @WebServlet and others, but encounters unknown byte code.
If one is using org.apache.tomcat.maven:tomcat7-maven-plugin to start embedded TomCat, you can follow this instruction.
