如何为JSP配置spring boot mvc app？ [英] How to configure spring boot mvc app for JSP?

问题描述

我是Spring boot（和servlet 3.0）的新手。我试图用JSP作为视图创建spring mvc项目。当我从我的控制器返回一个视图时，它没有被解析为JstlView。

I am new to Spring boot ( and servlet 3.0 ). I am trying to create spring mvc project with JSP as view. When I return a view from my controller it is not getting resolved as JstlView.

这是我做的：

@SpringBootApplication
public class MyApp extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(MyApp.class, args);
    }

}

---

---

@Controller
public class MainController {

    @RequestMapping( value="/main" , method = RequestMethod.GET  )
    public String main(){
        return "main";
    }

    @RequestMapping( value="/" , method = RequestMethod.GET  )
    public String welcome(){
        return "welcome";
    }
}

在 src\main\webapp\WEB-INF \ jsp 中创建了两个.jsp文件。

Created both .jsp files in src\main\webapp\WEB-INF\jsp .

谷歌搜索后我发现我需要在application.properties中指定这个，所以我在道具中添加了以下内容：

After googling I found that I need to specify this in application.properties So I added following in props:

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp


logging.level.org.springframework: TRACE
logging.level.com: TRACE

即使在此之后它也无效。这是跟踪。

Even after this it is not working. Here is the trace.

正如您在跟踪中看到的，这是尝试将/jsp/welcome.jsp解析为InternalResourceView而不是JstlView。最终它以404失败。

As you see in the trace, this is trying to resolve /jsp/welcome.jsp as InternalResourceView instead of JstlView. Eventually it fails as 404.

我需要遵循哪些其他步骤？ SpringBoot-mvc是否有任何jsp教程？

What other steps I need to follow? Is there any tutorial for SpringBoot-mvc with jsp ?

P.S。我可以使用web.xml使用jsp创建spring mvc app（在我的配置文件中使用JstlView）。但我找不到任何有关jsp的Spring启动mvc的教程。

P.S. I can create spring mvc app with jsp using web.xml ( using JstlView in my config file ). But I can't find any tutorial for Spring boot mvc with jsp.

推荐答案

@Bean
public ViewResolver getViewResolver(){
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    resolver.setViewClass(JstlView.class);
    return resolver;
}

也需要，你的网页应该是/ webapp / WEB-INF / jsp /

also needed and your pages should be at /webapp/WEB-INF/jsp/
