Исключение при использовании событий, отправленных сервером весной-mvc

Я новичок в весне. Я хочу использовать сервер посланный события в моем проекте, но я получаю это исключение в журнале сервера при тестировании SseEmitterИсключение при использовании событий, отправленных сервером весной-mvc

Вы используете этот код внутри контейнера? (Например, Tomcat). Если да, то в какой версии вы работаете? – DaveH

@DaveH Tomcat 6.0.47 –

Это связано с тем, что вы запускаете приложение в контейнере, который не поддерживает API сервлета v3 и выше. Tomcat 6 поддерживает только сервлет API v2.5.

Вам необходимо запустить его в более современном контейнере сервлетов. Tomcat 7 или выше.

Это потому, что servel муз имеют <async-supported>true</async-suported>

Пробовал добавить его в сервлет тег web.xml, но это не помогло –

Попробуйте добавить следующий код @WebFilter (urlPatterns = «/ *», asyncSupported = истина) –

Благодарности. Одна из проблем заключалась в том, что мне пришлось добавить true для фильтрации тоже, но основной причиной исключения была старая версия tomcat –
