Pessoal,

Estou tentando aplicar os conhecimentos que aprend nos cursos de spring mvc e spring boot. Está tudo funcionando perfeitamente quando rodo no eclipse. Porém, quando fui rodar o jar deu erro : erro no navegador: Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Tue Aug 22 12:00:22 BRT 2017 There was an unexpected error (type=Internal Server Error, status=500). Error resolving template "/views/home", template might not exist or might not be accessible by any of the configured Template Resolvers

Erro no console:

Estou suspeitando que seja a organização das minhas pastas, pois levei um tempo para descobrir que o spring boot possui pastas padronizadas

/META-INF/resources/ /resources/ /static/ /public/ /templates/

Porém, dentro destas pastas padronizadas pelo que achei na internet(não achei na documentação) não posso utilizar qualquer pasta. São padronizadas também (css, js, images).

criei várias pastas para organizar meus arquivos dentro destas subpastas.

também no aplication. properties alterei o server context:

server.contextPath=/minhaAplicacao

estou usando o spring security também.

Tudo no eclipse funciona normal e perfeito. Alguém saberia me explicar o motivo do erro quando rodo pelo jar gerado? Seriam as localizações dos meus arquivos de view (src/main/resources/templates/views), css (src/main/resources/static/css)e js(src/main/resources/static/js)? A organização das subpastas está correta?

Obrigado

Oi Francesco, tudo bem? Em algum lugar, você está retornando a view "/views/home" mas o Spring não está encontrando. Considerando isso, verifique se em "resources/templates/views/" existe o arquivo home.html, pois é esse que ele tá procurando.

No geral, como existe a padronização das pastas, você pode colocar o home.html direto dentro da pasta templates e no controller retornar apenas o "/home".

Wanderson,

Existe o arquivo, tanto que roda normal pelo eclipse. Já coloquei o home direto na pasta template para testar, roda normal no eclipse e não roda pelo jar.

solução!

Caso mais alguém tenha a mesma dúvida segue como resolvi. Por incrível que pareça o problema resolve retirando a "/" da frente dos caminhos nos returns dos controllers:

ex:

return "/views/home"; para return "views/home";

também tive que tirar a barra dos th:replace

ex:

<div
        th:replace="/views/agenda/modal/cadastrarEvento :: modalCadastrarEvento"></div>

para:

<div
        th:replace="views/agenda/modal/cadastrarEvento :: modalCadastrarEvento"></div>

assim roda tanto no eclipse quanto no jar. Agora ficou perfeito...

Interessante isso Francesco. Então no eclipse funcionava mas no jar final não, certo?

Fico feliz que tenha resolvido o problema sozinho, vou deixar seu post marcado como solução, tá bem? Lembra de marcar o post como solução nas próximas vezes.

Bons estudos! Abraço!
