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/
