Configuração completa básica para Jersey no Tomcat no eclipse
Sou novo em Jersey e estou tentando configurar um webapp básico usando o Tomcat e o eclipse. Analisei vários tutoriais e exemplos, mas todos são diferentes um do outro ou omitem parte do processo (por exemplo, com Spring, com um arquivo web.xml, implementando um aplicativo que não é de Jersey no Tomcat etc.) )
Aqui é onde estou até agora:
Eu criei um projeto dinâmico da Web chamado TestProject no eclipse e o convertei em um projeto automatizado.
Aqui está o meu pom.xml:

Eu tenho um pacotecom.test que contém 3 classes:
TestApplication para criar um aplicativo sem um web.xml:
@ApplicationPath("/*")
public class TestApplication extends ResourceConfig {
public TestApplication(){
packages("com.test");
register(JacksonFeature.class);
}
}
TestProvider como uma classe de recurso mínima:
@Path("/test")
public class TestProvider {
@GET
@Produces("application/json")
public Test getTest(){
return new Test();
}
}
Test como um objeto mínimo para retornar no formato JSON:
public class Test {
private String field = "test";
}
Eu tenho um servidor Tomcat em execução com o projeto adicionado como um módulo da web. Se eu executar o projeto (Executar como> Executar no servidor) e navegue atéhttp://localhost:8080/test ouhttp://localhost:8080/TestProject/test Eu recebo um tomcat 404 padrão.
Aqui está o meu log de inicialização do Tomcat:

Se eu criar um HttpServlet sem camisa com a anotação@WebServlet(name="hello",urlPatterns={"/hello"}), Recebo uma resposta emhttp://localhost:8080/TestProject/hello.
o que estou perdendo? Além disso, alguma das práticas recomendadas acima não é uma aplicação web básica? Parece que essa tecnologia muda rapidamente, e é difícil saber quais exemplos ou métodos estão desatualizados.
