Use jsp+servlert. After the content entered in the text box reaches the rightmost, the text content will automatically return to the line.
When I deposit it into the database and display it, I want to get content that is exactly in line with the input form, but I have no way to get it.
That is, I can only find hard pressed content but cannot recognize the content that automatically returns after the content is full.
I'm wondering now if there is a way to get a line-by-line reading from a text field, similar to reading a text file's readline

Line breaks in the text field cannot be displayed in the database, but they do exist

At this time, his effect in the text field is
ddddddddddddddddddddddddddddddddddd on time
dddddddddddddddd
Normally, it should be:
ddddddddddddPlace on timedddddddddddd
dddd
I wonder if there is a way to avoid this problem? Does the text field have such an attribute to control it will not wrap the line like in Method 2
