Deploy aplikacji na Tomcat :: 4programmers.net

** Witam, podczas wdrażania mojej aplikacji na Tomcat wszystko się kompiluje, po uruchomieniu serwera zostaję domyślnie przekierowany do przeglądarki, gdzie od razu jest wysłane żądanie: http://localhost:8080/demo2_war_exploded/ i tutaj pojawia się komunikat: **

HTTP Status 404 – Not Found
Type Status Report
Message The requested resource [/demo2_war_exploded/] is not available
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Apache Tomcat/9.0.39

** Gdy wpiszę localhost:8080 pojawia się błąd: **

HTTP Status 404 – Not Found
Type Status Report
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Apache Tomcat/9.0.39

** W pliku pom.xml dodałem paczkę wynikową jako war, po czym wykonałem Maven clean i compile, następnie w Edit Configurations wybrałem paczkę exploded.
Poniżej zamieszczam obie klasy, plik pom.xml oraz logi serwera **

Nie jestem pewien, ale spróbuj ten controller dać o pakiet niżej niż główna klasa uruchomieniowa, czyli np na package com.example.demo2.controller;

Zmień @RequestMapping("/") na @RequestMapping("/hello") i odpal localhost:8080/hello no i @Controller zmieniłym na @RestController

Nie działa, już próbowałem tego wcześniej

Czekaj czekaj, bo jest tutaj lekki zgrzyt - czemu Twój projekt buduje się do wara zamiast do jara? Przecież Spring Boot by default powinien zbudować jara, wewnątrz którego ma wbudowany Tomcat... Więc w Twoim pom.xml zamień war na jar, potem mvn package, i java -jar demo2-0.0.1-SNAPSHOT.jar

Ech, aż się smutno robi jak czytam te posty. Same jakieś pomysły z serii permutation driven development i zero zrozumienia co w ogóle robicie. Dramat.

@Karol8650 Spring Boot buduje ci jara który nie jest zgodny z javowym standardem jarów/warów. Wrzucanie go do tomcata to strata czasu, chyba ze dodasz sobie specjalne parametry do tego mavenowego plugina ( https://docs.spring.io/spring-boot/docs/1.5.x/maven-plugin/examples/repackage-classifier.html ), żeby wygenerował ci też "klasycznego" jara. Niemniej to nadal nie wystarczy dla tomcata, bo on potrzebuje jednak wara z tymi wszystkimi WEB-INF i innymi katalogami.
Nie kombinuj z tomcatem tylko odpal tego bootowego jara (java -jar cośtam.jar) i będzie działać, albo jak odpalasz z IDE to odpal po prostu maina z tej klasy Demo2Application

A kolegom z pomysłami w stylu zmień pakiet albo zmień Controller na RestCotroller to ...
