Performance of the problem:

Eclipse uses the spring-mvc framework to develop web projects, the project can visit the jsp page after normal start-up, but the page effect of the jsp page does not take effect, and prompts the jsp file to prompt js can not find, 404 error.

(1) preliminary judgment:

When debug in the browser, the jsp page indicates that the js file cannot be found and indicates a 404 error. Since the name of the project is littlec-exchange-center and the name of the project is exchangecenter in the url during the visit, it is preliminarily judged that the path is wrong.

Try to solve the problem: check the server.xml configuration under the conf path of tomcat as follows:

As you can see, although the path to the packaged file under tomcat is littlec-exchange-center, the access path is / exchangecenter. So there's nothing wrong with the path.

(2) continue to search: the js file cannot be found in the source view of the browser, but there is a js file in the project packaged into tomcat. It is further determined that there is a problem with the access of static files such as js.

Try to solve it: create a new test.html under the same path as the jsp file and write "test" in it. Accessing localhost:8080/exchangecenter/test.html directly or prompting a 404 error.

It can be basically determined that it is a problem of static resource access. The place where static resources are loaded in spring-mvc is in the dispatcher-servelt.xml file we defined. After spring-mvc3.0, it is recommended to use configuration:

After this configuration, spring can find it when the pumped _ picture _ picture _ CSS and other files have been placed in the resources file.
