有什么解决办法?
推荐答案
异常不言自明
by: java.lang.IllegalArgumentException: 名为 [com.staff.servlet.AllocationServlet] 和 [com.staff.servlet.SearchConditionServlet] 的 servlet 都映射到不允许的 url-pattern [/AllocationServlet]
您的两个 servlet 似乎是
It seems that two of your servlets namely
- AllocationServlet
- SearchConditionServlet
两者都映射到相同的 url-pattern AllocationServlet
both are mapped to the same url-pattern AllocationServlet
您需要修复 servlet 的 web.xml 或注释(在 Servlet3.0 的情况下)，并确保没有两个 servlet 映射到相同的 url-pattern.
You need to fix your web.xml or annotations ( in case of Servlet3.0) of the servlets and make sure no two servlets are mapped to the same url-pattern.
