我是 Spring boot(和 servlet 3.0)的新手。我正在尝试使用 JSP 作为 View 创建 spring mvc 项目。当我从我的 Controller 返回一个 View 时，它没有被解析为 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。

谷歌搜索后我发现我需要在 application.properties 中指定它所以我在 props 中添加了以下内容:

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


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

即使在这之后它也不起作用。这是踪迹。

正如您在跟踪中看到的，这是试图将/jsp/welcome.jsp 解析为 InternalResourceView 而不是 JSTLView。最终它以 404 失败。

我还需要执行哪些其他步骤？有没有 SpringBoot-mvc 和 jsp 的教程？

附言我可以使用 web.xml(在我的配置文件中使用 JSTLView)用 jsp 创建 spring mvc 应用程序。但是我找不到任何关于 Spring boot mvc with jsp 的教程。

最佳答案

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

还需要，你的页面应该在/webapp/WEB-INF/jsp/
