WELD-001408：注入点处带有限定符@Default的类型记录器的不满意依赖关系[BackedAnnotatedField]@Inject

Question

我在使用Arquillian测试JavaEE8应用程序时遇到了这个问题： WELD-001408：类型记录器与限定符@默认在注入点[BackedAnNotatedField]@注入私有academy.learnprogramming.services.TodoService的未满足依赖项。LOG

我对EntityManager也有同样的错误

以下是我的课程：

TodoService。类（我必须测试的类）

package academy.learnprogramming.services;

import academy.learnprogramming.entities.Todo;
import org.apache.log4j.Logger;

import javax.annotation.PostConstruct;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.transaction.Transactional;
import java.util.List;

@Transactional
public class TodoService {

    @Inject
    private Logger LOG = Logger.getLogger(TodoService.class);

    @Inject
    EntityManager entityManager;

    public Todo createTodo(Todo todo) {
        //Persist into db
        entityManager.persist(todo);
        return todo;
    }

    public Todo updateTodo(Todo todo) {
        entityManager.merge(todo);
        return todo;
    }

    @PostConstruct
    private void init() {
        LOG.info("Bean TodoService created");
    }

    public Todo findTodoById(Long id) {
        return entityManager.find(Todo.class, id);
    }

    public List<Todo> getTodos(){
        return entityManager.createQuery("SELECT t from Todo t", Todo.class).getResultList();
    }

}

TodoService测试。类（用于测试的类）

package academy.learnprogramming.services;

import academy.learnprogramming.config.Producers;
import academy.learnprogramming.entities.Todo;
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.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;

import static org.junit.Assert.*;

@RunWith(Arquillian.class)
public class TodoServiceTest {

    @Deployment
    public static JavaArchive createDeployment() {
        return ShrinkWrap.create(JavaArchive.class)
                .addClasses(TodoService.class, Todo.class, Producers.class)
                .addAsResource("persistence.xml", "META-INF/persistence.xml")
                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
    }

    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void createTodo() {
    }

    @Test
    public void updateTodo() {
    }

    @Test
    public void findTodoById() {
    }

    @Test
    public void getTodos() {
    }
}

制片人。类（用于将第三方库添加到CDI的类）

package academy.learnprogramming.config;


import org.apache.log4j.Logger;
import org.dozer.DozerBeanMapper;

import javax.enterprise.context.RequestScoped;
import javax.enterprise.inject.Produces;
import javax.enterprise.inject.spi.InjectionPoint;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import java.util.ArrayList;
import java.util.List;

//If producers becomes complitated, split it in many classes, each for a single producer
public class Producers {

    @Produces
    @PersistenceContext
    EntityManager entityManager;

    @Produces
    public Logger produceLogger(InjectionPoint injectionPoint) {
        return Logger.getLogger(injectionPoint.getMember().getDeclaringClass().getName());
    }

    //Auto mapper
    @Produces
    public DozerBeanMapper produceDozenBeanMapper() {
        DozerBeanMapper mapper = new DozerBeanMapper();
        List<String> mappingFiles = new ArrayList();
        mappingFiles.add("dozerJdk8Converters.xml");
        mapper.setMappingFiles(mappingFiles);
        return mapper;
    }
}

四处搜索，我了解到可能的问题可能是：

1. 豆子。如果不使用bean discovery mode=“all”，xml可能会出现问题，因为它不会扫描没有注释的bean，而是我的bean。xml文件具有bean discovery mode=“all”

如果我删除@Inject注释，并从类中使用logger，它就会工作。

我还能尝试什么？非常感谢您抽出时间。

Answer 1

如果使用WAR文件，请尝试使用WebArchive

 @Deployment
    public static WebArchive createDeployment() {
        return ShrinkWrap.create(WebArchive.class)
                .addClasses(TodoService.class, Todo.class, Producers.class)
                .addAsResource("persistence.xml", "META-INF/persistence.xml")
                .addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
}

卸下记录器。getLogger（TodoService.class） 生产者它将实例化记录器。

@RequestScoped
@Transactional
public class TodoService {

    @Inject
    private Logger log;

    @Inject
    EntityManager entityManager;

    public Todo createTodo(Todo todo) {
        //Persist into db
        entityManager.persist(todo);
        return todo;
    }

    public Todo updateTodo(Todo todo) {
        entityManager.merge(todo);
        return todo;
    }

    @PostConstruct
    private void init() {
        log.info("Bean TodoService created");
    }

    public Todo findTodoById(Long id) {
        return entityManager.find(Todo.class, id);
    }

    public List<Todo> getTodos(){
        return entityManager.createQuery("SELECT t from Todo t", Todo.class).getResultList();
    }
