How to integrate “old spring mvc controllers with jsp” and “vaadin7 ui” together

问题

I am trying to integrate vaadin with my spring mvc application. I have a some url with jsp files that spring mvc controller use them For example : mysite.com/spring/ mysite.com/spring/examples mysite.com/spring/examples/1.jsp

I want to add vaadin in this path: mysite.com/vaadin/MainUI

here is my web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.1"
  xmlns="http://java.sun.com/xml/ns/j2ee" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-app_3_1.xsd"
      metadata-complete="true">

  <display-name>vaadin-spring</display-name>

  <!-- Turn off productionMode (off by default). Setting productionMode=true disables 
       debug features. In when this is off, you can show debug window by adding ?debug to 
       your application URL. Always set this true in production environment. -->

    <param-name>productionMode</param-name>
    <param-value>false</param-value>

  <servlet-mapping>

    <servlet-mapping>
        <servlet-name>vaadin-spring</servlet-name>
        <url-pattern>/VAADIN/*</url-pattern>
    </servlet-mapping>

  <!-- spring -->
  <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>spring.profiles.active</param-name>
            <param-value>local</param-value>
        </init-param>
  </servlet>
  <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

Here is my spring main controller:

@Controller
@RequestMapping("/")
public class MainController {

    @RequestMapping(value = "{jspFile}")
    public String map(@PathVariable String jspFile) throws IOException {
        return jspFile;
    }

    @RequestMapping(method = RequestMethod.GET)
    public String map1() throws IOException {
        return "index";
    }

}

Here is working example (after fix) in github https://github.com/prilia/IntegrationSpringMvcVaadinUI

回答1:

So after some tries i've ended up with a JSP compile exception, which i believe is reasonable since you provided a test example on github. So far here's what i've done:

web.xml

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

MainController.java

@Controller
@RequestMapping("/")
public class MainController { ...

spring-servlet.xml i've added

<bean name="spring" class="org.nli.deposit.controller.MainController" />

Now seems it resolves the url:

http://localhost:8080/springMvcTest/ goes to JSPs

http://localhost:8080/springMvcTest/vaadin goes to Vaadin

it just crashes during JSP compilation, but that's a whole another question. Try on your complete project and let me know!
