Druid报错c.a.druid.pool.DruidAbstractDataSource : discard long time none received connection.

在网上看了很多说的解决办法，修改版本，修改配置的好像都不行，可以试试这个。

我这里测试结果：
1、类文件配置，增加配置（在我这里无效）

@PostConstructpublic void init(){// 处理 discard long time none received connectionSystem.setProperty("druid.mysql.usePingMethod", "false");}

2、相应调整了mysql的版本（在我这里也无效）

3、在运行参数中增加：-Ddruid.mysql.usePingMethod=false（有效）

nohup java -Ddruid.mysql.usePingMethod=false -jar user-0.0.1-SNAPSHOT.jar --server.port=9092  >user.out &

就是在启动命令上加这个，我这里启动命令有其他的，可以跟在后面就行：
