我在用arquillian:weld-001408测试javaee8应用程序时遇到了这个问题:类型记录器的依赖关系不满意,限定符@default at injection point[backedannotatedfield]@injectprivate academy.learnprogramming.services.todoservice.log
我对entitymanager也有同样的错误
以下是我的课程:
todoservice.class(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();
}
}
todoservicetest.class(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() {
}
}
producers.class(用于向cdi添加第三方库的类)
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;
}
}
四处寻找,我了解到可能的问题可能是:
如果不设置bean discovery mode=“all”,beans.xml可能会出现问题,因为它不会扫描未注解的bean,但我的beans.xml文件具有bean discovery mode=“all”
注入todoservice类的logger和entitymanager不能有producer,但我有producers类
在导入todoservice、todoservicetest和producers类的logger类的过程中,人们可能会犯错误,例如在一个类中导入org.apache.log4j.logger,在另一个类中导入java util.logging.logger,但是我的所有类都带有import org.apache.log4j.logger
如果我删除@inject注解并从类中使用logger,它就会工作。
我还能试什么?非常感谢您抽出时间。

如果使用war文件,请尝试使用webarchive
拆下
Logger.getLogger(TodoService.class);
它将示例化记录器。
