laorenzixun.setUserid((Long)request.getSession().getAttribute("userId")); laorenzixunService.insert(laorenzixun);
These lines of code are related to inserting a new record in the "laorenzixun" table. The "setUserid" method is used to set the value of the "userid" field in the "laorenzixun" object with the value retrieved from the session attribute "userId". This is done to associate the current user with the record being inserted.
The "laorenzixunService.insert(laorenzixun)" method is then called to insert the "laorenzixun" object into the database using the service layer. This may involve invoking the appropriate DAO (Data Access Object) methods to perform the actual database operations.
Overall, these lines of code are used to persist user input or data into the database and ensure that it is associated with the correct user.
setUserid((Long)request.getSession().getAttribute("userId"));
This line of code retrieves the userId attribute from the current session and casts it to a Long data type, then sets it as the value of the userId variable for the current user. This is typically used in web applications to maintain user state across multiple requests.
