Простой подпружиненный jar-файл не работает, за исключением папки build / target

/ 22 апреля 2020

У меня есть простое приложение для весенней загрузки, но оно не работает, кроме запуска из папки target / build.

Вот все мои настройки и файлы. Пожалуйста, помогите мне выяснить, почему он не работает и что я делаю неправильно.

Он прекрасно работает, когда я бегу из целевой папки java -jar target\demo-0.0.1-SNAPSHOT и из IDE (Eclipse).

и мой weburl http://localhost:8082/demo/edit.html. Я только что скопировал эту банку на другую машину / папку, она больше не работает. 

package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}


package com.example.demo;
import java.io.UnsupportedEncodingException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class DemoContoller {
    @RequestMapping("/edit.html")
    public ModelAndView edit(HttpServletRequest request, HttpServletResponse response)
            throws UnsupportedEncodingException {

        ModelAndView model = new ModelAndView("edit");
        return model;
    }

}


package com.example.demo;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@Configuration
@EnableWebMvc
@ComponentScan
public class MvcConfiguration extends WebMvcConfigurerAdapter
{
    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/view/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        registry.viewResolver(resolver);
    }
}

Я просто запускаю mvn clean package spring-boot:repackage, чтобы построить проект.

Вот моя структура проекта / папки:

Обновление удалено из application.yaml, поэтому теперь я вижу эту страницу ошибки.

edit. html может быть проблемной частью c. Можете ли вы удалить. html и оставить только "/ edit", а затем попробуйте "http://localhost: 8082 / demo / edit ". Если это сработает, мы поймем, что это связано с расширением файла.

...
