war文件部署在外部tomcat中，但应用程序url没有加载jsp页面。同一个应用程序能够在ecllipse中运行和加载jsp页面，也可以在Com和promt中使用

mvn spring-boot:run

在这种情况下，有人能帮我吗。

@SpringBootApplication
public class AccountsApplication extends SpringBootServletInitializer {

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

@Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(AccountsApplication.class);
   }

 }

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

4.1安全配置文件

@Override
protected void configure(HttpSecurity http) throws Exception {

    http
        .csrf().disable()
        .authorizeRequests()
            .antMatchers("/res/**","/test/**").permitAll()

            .clearAuthentication(true)
            .logoutSuccessUrl("/logoutsuccess").permitAll();

}

控制器代码

package com.accounts.Controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class LoginController {

@GetMapping("/login")
public String login() {
   return "login";
}

@GetMapping("/logoutsuccess")
public String logout() {
   return "login";
}
