WELD-001408类型[Logger]与注入点[[field]使用arquillian的限定符[@Default]不满意的依赖关系

Question

我正在使用arquillian网站上的Greeter示例运行基本的arquillian单元测试.唯一的区别是我在Greeter.java中的greet(PrintStream to,String name)函数中执行了log.debug.我使用slf4j进行日志记录.

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

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");
    }   

}

获得WELD-001408运行测试时,在注入点[[field] @Inject private org.arquillian.example.Greeter.log]错误的类型[Logger]的类型[Logger]的不满意依赖性.有人可以帮忙吗？

Answer 1

这是一个CDI问题.你首先没有生产者Logger.

其次,任何此类生产者都应添加到ShrinkWrap部署中.

Logger的生产者通常是这样编写的:

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());
  }
}

该生成器接收注入点并继续返回SLF4J Logger实例.该实例与包含注入点的类具有相同的名称.

还将 bean.xml bean-discovery-mode 更改为 all

bean-discovery-mode="all"
