The client was disconnected by the server because of inactivity异常处理？

Question

提示异常信息如下

The client was disconnected by the server because of inactivity. See wait_timeout and interactive_timeout for configuring this behavior

mysql interactive_timeout 和 wait_timeout 如下

interactive_timeout    7200
wait_timeout    7200

Druid配置如下

      initial-size: 5                                      
      min-idle: 5                                          
      max-active: 50                                       
      max-wait: 60000                                      
      time-between-eviction-runs-millis: 60000             
      min-evictable-idle-time-millis: 300000                
      test-on-borrow: false
      test-on-return: false
      validation-query: SELECT 1
      test-while-idle: true

尝试按自己的理解去配置了，但是依然出现如题所示的异常，请大佬指点一下
