在wildfly回报休息“未找到”，但JSP的作品，有什么不对？

问题描述 投票：0回答：1

我开始学习休息和我尝试做REST返回Aluno，当我将测试的“邮差”或一个JSON“火狐”我收到此404错误，但疗法是不访问JSP没有问题。

我尝试了很多想，我改变了的休息，容易，休眠，尝试做另一种休息，但只有相同的答案版本。

技术应用于：wildfly，RestEasy的，EasyCriteria，JPA，休眠。

网址：http://localhost:8080/teachmanager/ws/aluno

怎么了？！

休息：

@Path("aluno")
public class AlunoRest {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String busca() {
        Dao<Aluno> dao = new Dao<Aluno>(JPAUtil.getEntityManager(), Aluno.class);
        Aluno aluno = dao.getById(1);
        return aluno.toJson();
    }

}

我改变Web模块版本3.0和多数民众的作品！但我不明白为什么不上3.1工作！

我发现一个新的方式来做到这一点的web服务，不使用的web.xml。

我创建一个配置类：

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("service")
public class RestManager extends Application{

}

并创建一个正常的休息类：

@Path("teste")
public class Teste {

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String getTeste() {
        return "teste";
    }


    @GET
    @Path("lista")
    @Produces(MediaType.APPLICATION_JSON)
    public String lista() {
        String ret = "";
        try {
            Dao<Aluno> dao = new Dao<Aluno>(JPAUtil.getEntityManager(), Aluno.class);
            List<Aluno> lista = dao.getAll();
            ret = new Gson().toJson(lista);
        } catch (Exception e) {
            ret = new Gson().toJson(e.getMessage());
        }

        return ret;
    }



}
