Solution to the problem that struts and servlet cannot coexist

In a project, if we use both struts 2 and servlet, we may not be able to access the servlet normally when the project is running because all requests are intercepted when configuring the struts filter.

The following is the servlet configuration

When we make a request on the page, struts 2 will intercept all requests and will not respond normally to servlet requests

The error message is: HTTP status 404 - there is no action mapped for namespace / and action name myservlet

This is because struts 2 regards servlet as action, because both servlet and action have no suffix

resolvent:

Three methods are described below

Method 1:

Add after servlet Servlet end, including web Where servlets are used in XML configuration files and pages (of course, anything, such as hello)

Page access http://localhost:8080/project/MyServlet.servlet

Method 2:

In struts Add the request suffix constant processed by struts 2 under the node in XML:

This attribute specifies the request suffix to be processed by struts 2. The default value of this attribute is action, that is, all matching * Action requests are processed by struts 2. If the user needs to specify multiple request suffixes, the suffixes are separated by English commas (,).

Method 3:

On the web Modify the configuration of struts 2 intercepting page requests in XML:

customary

Change to

The request path of the servlet does not change
