Servlet. service () for servlet [appServlet] in context with path [/item] threw exception [Request processing failed,

A small mistake I made before, but I forgot how to modify it, so I 'd better record it.

 

Severe: Servlet. service () for servlet [appServlet] in context with path [/item] threw exception [Request processing failed; nested exception is java. lang. numberFormatException: For input string: "1"] with root cause
Java. lang. NumberFormatException: For input string: "1"

After searching, I found that there is an error behind the page in the address bar.

That is the paging attribute. After finding the page for a long time, I found that there was no error. Finally, I found that there was a space after the page attribute.

I hope you will remember to delete useless spaces in the future.
