spring.view.prefix = /WEB-INF/jsp/
spring.view.suffix = .jsp

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

两个都试过了

启动类

@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {

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


    @Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DemoApplication.class);
}
