Maven Spring MVC GWT Thymeleaf — шаблон для устранения ошибок «ошибка»

#javascript #java #spring #maven #gwt

Вопрос:

В течение нескольких дней у меня была проблема с запуском приложения spring. Предполагается, что он использует Spring Boot, интеграцию, безопасность, Web MVC и имеет GWT поверх этого. Springboot запускается и работает нормально, но как только я повторно запрашиваю страницу, я получаю эту ошибку:

Я был бы признателен за любую помощь, поскольку я трачу несколько дней на поиск в Google, пробуя разные вещи, и пока не могу заставить его работать. Надеюсь, я предоставил всю необходимую информацию.

Комментарии:

1. вы используете плагин maven-war и плагин spring-boot-maven, этого должно быть достаточно, чтобы создать войну из spring-boot-maven. есть ли причина, по которой вы используете плагин maven-war docs.spring.io/spring-boot/docs/current/reference/htmlsingle /…

2. Я удалил зависимость, проблема осталась прежней. Однако, просматривая журнал загрузки spring, я столкнулся с этим: 2016-10-16 23:37:26.399 INFO 11004 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error]}" onto public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest) Похоже, я должен это переопределить? Потому что я не помню, как это настраивал.
