Spring mvc não sobe no Jboss EAP 7

Lucianomagalhaes · Julho 30, 2019, 6:32pm

Boa tarde,

minha aplicação com spring mvc sobe normal e funciona respondendo as requisições no tomcat, porém no Jboss EAP 7 apresenta o erro abaixo ao tentar subir a aplicação. Não consegui encontrar a solução, parece que já existe registrado uma outra servlet, podem me ajudar?

Console apresenta:

14:52:57,170 ERROR [org.jboss.web] (ServerService Thread Pool -- 77) JBAS018202: Erro ao chamar onStartup para o inicializador do recipiente servlet: org.springframework.web.SpringServletContainerInitializer: java.lang.IllegalArgumentException: Failed to register servlet with name 'dispatcher'.Check if there is another servlet registered under the same name.

Atualizando o cenário…

O problema quanto ao deploy não ocorre mais, o erro ocorria pois conforme o próprio erro informava, havia outro servlet já registrado com o mesmo nome e isso ocorria por lixo na pasta de deploy do servidor, …\jboss-eap-7.0\standalone\deployments, depois de limpar a aplicação subiu sem erro, porém agora ao enviar uma requisição a mesmo apresenta status 404, alguém sabe porque?

Consegui resolver a princípio modificando o código da minha classe Servlet (ServletSpringMVC) conforme abaixo, porém não fiquei satisfeito por ter que realizar o extends de AbstractDispatcherServletInitializer e não de AbstractAnnotationConfigDispatcherServletInitializer que já uma extensão da mesma, além de escrever mais código…então voltei a implementação anterior e acrescentei apenas um “" em getServletMappings, ficando "/”, isso após mais uma vez limpar a pasta de deploy do servidor. Como não aparecia no console mais nenhum erro e o mapeamento do método estava listado, Mapped “{[/executa/teste],methods=[GET],produces=[application/json]}”, então fiz esse teste e funcionou. Só observei que o Servlet(ServletSpringMVC ) não aparece carregado na listagem do console, mas funcionou!!!

Minha initializer class com o teste

public class ServletSpringMVC extends AbstractDispatcherServletInitializer {

@Override
protected WebApplicationContext createRootApplicationContext() {
	AnnotationConfigWebApplicationContext applicationContext =
			new AnnotationConfigWebApplicationContext();
	applicationContext.register(ApiConfiguration.class);

	return applicationContext;
}

@Override
protected WebApplicationContext createServletApplicationContext() {
	AnnotationConfigWebApplicationContext applicationContext =
			new AnnotationConfigWebApplicationContext();
	applicationContext.register(ApiConfiguration.class);

	return applicationContext;
}

@Override
protected String[] getServletMappings() {
	return new String[]{"/*"};
}

}

Minha initializer class como ficou no final, aff brincadeira heim…

public class ServletSpringMVC extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {
	return new Class[] {ApiConfiguration.class};
}

@Override
protected Class<?>[] getServletConfigClasses() {
	return null;
}

@Override
protected String[] getServletMappings() {
	return new String[] {"/*"};
}

}
