WELD-001408使用Arquillian在注入点[[field])上带有限定符[@Default]的[Logger]类型的依赖关系不令人满意 [英] WELD-001408 Unsatisfied dependencies for type [Logger] with qualifiers [@Default] at injection point [[field] using arquillian

问题描述

我正在使用基础站点​​上的Greeter示例运行基础的基础单元测试.唯一的区别是，正在Greeter.java中的greet(PrintStream to，String name)函数中执行log.debug.我正在使用slf4j进行记录.

I am running a basic arquillian unit test, using the Greeter example on the arquillian site. The only difference is that am doing a log.debug in the greet(PrintStream to, String name) function in Greeter.java. Am using slf4j for logging.

Greeter.java

Greeter.java

package org.arquillian.example;
import java.io.PrintStream;

import javax.inject.Inject;

import org.slf4j.Logger;

public class Greeter {

@Inject
private Logger log;

    public void greet(PrintStream to, String name) {
        log.debug("Greeter Testing");
        to.println(createGreeting(name));
    }

    public String createGreeting(String name) {
        return "Hello, " + name + "!";
    }   

}

GreeterTest.java

GreeterTest.java

package org.arquillian.example;

import javax.inject.Inject;

import org.jboss.arquillian.container.test.api.Deployment;
import org.jboss.arquillian.junit.Arquillian;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.jboss.shrinkwrap.api.asset.EmptyAsset;
import org.jboss.shrinkwrap.api.spec.JavaArchive;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;


@RunWith(Arquillian.class)
public class GreeterTest {

    @Inject
    Greeter greeter;    


    @Deployment
    public static JavaArchive createDeployment() {
        return ShrinkWrap.create(JavaArchive.class)
            .addClass(Greeter.class)
            .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
    }

    @Test
    public void should_create_greeting() {

        Assert.assertEquals("Hello, Earthling!",
            greeter.createGreeting("Earthling"));
        greeter.greet(System.out, "Earthling");
    }   

}

在运行测试时，在注入点[[field] @Inject private org.arquillian.example.Greeter.log]上，带有限定符[@Default]的类型[Logger]的类型[Logger]的依赖项未得到满足.有人可以帮忙吗?

Am getting WELD-001408 Unsatisfied dependencies for type [Logger] with qualifiers [@Default] at injection point [[field] @Inject private org.arquillian.example.Greeter.log] error when running the test. Can someone please help on this?

推荐答案

这是CDI问题.首先，您没有Logger的生产者.

This is a CDI issue. You don't have a producer for your Logger in the first place.

第二，任何此类生产者都应添加到ShrinkWrap部署中.

Secondly, any such producer should be added to the ShrinkWrap deployment.

记录器的生产者通常是这样写的:

A producer for the Logger is usually written as such:

import javax.enterprise.inject.Produces;
import javax.enterprise.inject.spi.InjectionPoint;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class SLF4JProducer {

  @Produces
  public Logger producer(InjectionPoint ip){
    return LoggerFactory.getLogger(
      ip.getMember().getDeclaringClass().getName());
  }
}

此生产者接收注入点，然后继续返回SLF4J Logger实例.该实例与包含注入点的类具有相同的名称.

This producer receives an injection point and proceeds to return a SLF4J Logger instance. The instance has the same name as the class containing the injection point.
