web-->jsp files-->encoding (UTF-8), the encoding of the linked HTML Files also changed.
② configuration jdk:java-->installed jres-->add, find your jdk,finally on the line, finally you can see a JDK was added
③ Configuring the Tomcat server: Server-->runtime Environm-->add, find your tomcat and finish.
