1. Obtain the URI of the Request Path. For example, the URL is http: // server/struts2/path1/path2/path3/test. Action.

2. first, find the package whose namespace is/path1/path2/path3. If this package exists, search for the action named test in this package. If this package does not exist, go to step 3;

3. Find the package whose namespace is/path1/path2. If this package exists, search for the action named test in this package. If this package does not exist, go to step 4;

4. Find the package whose namespace is/path1. If the package exists, search for the action named test in the package. If the package still does not exist, step 5

5. Go to the default namaspace, that is, find the action named test under the package with an empty namespace. If the action still cannot be found, the page prompts that the action cannot be found.
