Question

部署EAR时出现此错误：

引起： org.jboss.as.server.deployment.DeploymentUnitProcessingException： WFLYEJB0406：找不到类型为interface的EJB ＆＃39; it.ejb32.ConverterBean＆＃39;用于绑定 it.webtest.SessionBeanTest / converterBean＆＃34;}，

这里有一些代码：

接口

package it.ejb32;

public interface Converter {
   float celsiusToFahrenheit(float temperature);
   float fahrenheitToCelsius(float temperature);
}

ConvertBean

package it.ejb32;

import javax.ejb.Local;
import javax.ejb.Stateless;

@Stateless
@Local
public class ConverterBean implements Converter {

    public ConverterBean() {}

    @Override
    public float celsiusToFahrenheit(float temperature) {
        return temperature * 1.8f + 32;
    }

    @Override
    public float fahrenheitToCelsius(float temperature) {
        return (temperature - 32) / 1.8f;
    }
}

的Servlet

import java.io.IOException;

import javax.ejb.EJB;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import it.ejb32.ConverterBean;

@WebServlet("/SessionBeanTest")
public class SessionBeanTest extends HttpServlet {

    private static final long serialVersionUID = 1L;

    @EJB
    private ConverterBean converterBean;

    public SessionBeanTest() {}

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        System.out.println("Conversion test:"+ converterBean.celsiusToFahrenheit(Float.parseFloat(request.getParameter("p"))));
    }

}

我是否需要使用 @Inject 接口而不是bean？

谢谢

没有找到带接口的EJB
