Org. Apache. Catalina. loader. devloader overrides final method start. () V

Define final with reference to metadata.

Later I found another author's solution:

Solution: Remove activedevloader from the Tomcat settings of the project, or remove devloader from the XXX. xml file of the project in the \ conf \ Catalina \ localhost directory of Tomcat. Tomcat 7 is available.

 

With myeclipse, you can directly use its server to publish the Web to the webapp directory of Tomcat. However, if you do not know why, some configuration files are often not released, open the classpath path, there is no such configuration file shadow in it. I haven't checked the class file, and I don't know if it will be too small. So there are often some beans that cannot be instantiated, beans are not defined, and so on, depressed.
