1. First set up an empty springboot project.
2. Add the integration servlet with jsp files need to rely on prom.xml springboot project:
3. application.properties configuration file:
## JSP configuration (when the page jump directly write / WEB-INF / jsp / rear portion to .jsp)
# page default prefix
spring.mvc.view.prefix = / WEB-INF / jsp /
# default page response suffix
spring.mvc.view.suffix = .jsp such as:
# Use ServletFileUpload upload files (the old project file upload servlet is ServletFileUpload, so the spring is turned off)
spring.http.multipart.enabled = false
4. web.xml arranged in the servlet transformed into SPRINGMVC (in AdminServlet example)
Such a change service layer with the same layer dao
Because dao layer to interact with the database using a QueryRunner, if the persistent manner springboot provided to change the feeling of the code will increase a lot, but with QueryRunner, it must provide c3p0-config.xml configuration file, so here's resource package there c3p0-config.xml file under:
5. The next step is static style, js, image storage location (this is key, it is best to configure according to the original jsp page references a directory, or to change things on more), such as:
This style reference main.css I like this, I need to set up springboot engineering static resource storage location:
Engage in a class, the location pointed to static storage resource today the following:
So when this reference style, or the original: /jsps/css/main.css. What other pictures also built according to the original directory in a static directory, and then put the resources into them, such page references resources almost do not change.
6. Then the original jsp page calls need to change it:
7. Finally engage in a filter, the need to intercept the request set about:
In this class there MyFilter write their own processing logic.
8. Summary:
Such a change need to change something fairly small, because, after all, is an old project to switch to a different frame, I think the code aspects, especially in terms of SQL, if raw mybatis change or hibernate, it also increased a lot SQL configuration file, code changes also It will be much larger, so the changes as small as possible.
