是否可以在现有Servlet-Jsp项目中的Spring框架中添加新模块

Question

I have a requirement to add a new module(on Spring framework) in an Existing Project (on Servlet-Jsp Technology). I have to convert the Login Authentication module of project in Spring Technology. Is it possible, if Not then What is the other way for it. Actually that's a live project and very vast. So we want to slowly migrate the whole project from Servlet-JSP to Spring. Plz Guide me regarding that. Thank you.

Answer 1

Just map spring servlet in your web.xml to the separate url and step-by-step move you servlets to spring controllers.

web.xml

<servlet>
    <servlet-name>spring-web</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>spring-web</servlet-name>
    <url-pattern>/spring/*</url-pattern>
</servlet-mapping>

In this example all requests with path started from /spring will be addressed by spring-web meanwhile other servlets should continue to work as before.
