Ajuda para configurar Spring MVC

chuck4forum · Abril 28, 2017, 8:21pm

Olá,

Estou querendo ajuda para confgurar o spring MVC. Estou usando eclipse luna.

Acabei colocando os .jar do spring no próprio eclipse.

Existe uma configuração para fazer no web.xml. Para que server? Preciso fazer algo a mais?
Caso conheçam algum tutorial para instalação agradeço.

Chuck,

No proprio site do Spring MVC: https://spring.io/guides/gs/serving-web-content/

Olá BlackDog ou outra pessoa.

Baixei as.jars do site.
Porém meu apache tomcat não incicializa.

Alguém pode me ajudar. Será a primeira vez que uso o springMVC.

Segue meu web.xml

Brother,

Posta o stacktrace do start do tomcat, só assim podemos ajudar.

chuck4forum · Abril 29, 2017, 3:52am

Ok.

Vou colocar. mas estou jogando meu burro aqui, para fazer funcionar a primeira vez o Spring.
No web.xml que postei na tag init-param param-value existe um /WEB-INF/spring-contex.xml.
Esse arquivo spring-contex.xml, não existe no meu projeto.

Precisava de dicas básicas. parece bobo, mas preciso saber esse tipo de coisa. tenho de criar esse arquivo? Apos essa resposta vou colocar o log do apache.

Grato

O /WEB-INF/spring-contex.xml deve ser criado sim, porem pode ser qualquer outro nome. A apostila ou qualquer outro meio que você está utilizando para estudar deve ter informado como configurar .
Se ela não te informou nada segue uma que tem o passo a passo :

https://www.tutorialspoint.com/springmvc/index.htm

https://www.caelum.com.br/apostila-java-web/spring-mvc/

aqui meu repositorio com um exemplo simples:

Acabei não conseguindo subir o apache tomcat 8.
Por alguma razão não funciona.
Segue o conteudo do start do tomcat.
