如何集成“旧的spring mvc控制器与jsp"和“vaadin7 ui"一起 [英] How to integrate "old spring mvc controllers with jsp" and "vaadin7 ui" together

问题描述

我正在尝试将 vaadin 与我的 spring mvc 应用程序集成.我有一些带有 jsp 文件的 url，spring mvc 控制器使用它们例如 :mysite.com/spring/mysite.com/spring/examplesmysite.com/spring/examples/1.jsp

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

我想在此路径中添加 vaadin:mysite.com/vaadin/MainUI

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

这是我的 web.xml

here is my web.xml

</web-app>

这是我的弹簧主控制器:

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";
    }

}

这是github中的工作示例(修复后)https://github.com/prilia/IntegrationSpringMvcVaadinUI

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

推荐答案

所以经过一些尝试，我最终得到了一个 JSP 编译异常，我认为这是合理的，因为您在 github 上提供了一个测试示例.到目前为止，这是我所做的:

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>

主控制器.java

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

spring-servlet.xml 我已经添加

spring-servlet.xml i've added

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

现在看来它解析了网址:

Now seems it resolves the url:

http://localhost:8080/springMvcTest/ 转到 JSP

http://localhost:8080/springMvcTest/vaadin 转到 Vaadin

它只是在 JSP 编译期间崩溃，但这是另一个问题.试试你的完整项目并告诉我！

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