在Wildfly上有效的注射不适用于Weld-Se.其他注射剂对两者都有作用

Question

我很难在独立的焊接容器中注射工作。它在库代码中也在野生蝇容器上运行。其他注射在焊接容器中起作用，只是一个给我麻烦。我尝试通过secontainerinitializer专门添加类和界面。而且我尝试创建工厂并使用生产方法。

上课上的注释(这是javax.inject.singleton(。它有一个公共参数构造函数

package com.ticomgeo.ftc.util;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory; 
import javax.annotation.PostConstruct;
import javax.inject.Singleton;
import java.util.concurrent.Callable;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.ScheduledFuture;
import java.util.concurrent.TimeUnit;
  @Singleton
  public class ExecutorImpl implements RITExecutor {
  private  static  ScheduledExecutorService TIMER = executors.newSingleThreadScheduledExecutor();
  private static final Logger LOG = LoggerFactory.getLogger(new Throwable().getStackTrace()[0].getClassName());
  public ExecutorImpl() { super(); }
  @PostConstruct
    void initImpl() {     
    LOG.info("======================================Initializedingleton");
  }
  @Override
  public  void dispose() {
    TIMER.shutdownNow();
  }
  @Override
  public boolean isDisposed() {
    return TIMER.isShutdown();
  }
  @Override
  public <J> ScheduledFuture<J> schedule(Callable<J> job, long delay, TimeUnit unit) {
    return TIMER.schedule(job, delay, unit);
  }
  @Override
  public ScheduledFuture<?> schedule(Runnable job, long delay, TimeUnit unit) {
    return TIMER.schedule(job, delay, unit);
  }
  @Override
  public <J> Future<J> submit(Callable<J> job) {
    return TIMER.submit(job);
  }
  @Override
  public  Future<?> submit(Runnable job) {
    return TIMER.submit(job);
  }
  @Override
  public  <J> Future<J> submit(Runnable job, J result) {
    return TIMER.submit(job, result);
  }
}

接口

package com.ticomgeo.ftc.util;
import javax.inject.Singleton;
import java.util.concurrent.Callable;
import java.util.concurrent.Future;
import java.util.concurrent.ScheduledFuture;
import java.util.concurrent.TimeUnit;
public interface RITExecutor {
    void dispose();
    boolean isDisposed();
    <J> ScheduledFuture<J> schedule(Callable<J> job, long delay, TimeUnit unit);
    ScheduledFuture<?> schedule(Runnable job, long delay, TimeUnit unit);
    <J> Future<J> submit(Callable<J> job);
    Future<?> submit(Runnable job);
    <J> Future<J> submit(Runnable job, J result);
}

注射

@Inject
RITExecutor executor;

焊接bootstrap

  public static void main(String[] args) {
    SeContainerInitializer initializer = SeContainerInitializer.newInstance();
    /* disable discovery and register classes manually */
    try (SeContainer container = initializer.disableDiscovery()
        .addPackages(FTCServer.class)
        .addPackages(RITServer.class)
        .addPackages(Config.class)
        .addBeanClasses(ExecutorImpl.class, RITExecutor.class)
        .addPackages(AbstractConnection.class)
        .initialize()) {
    container.select(RITServer.class);
}

当我尝试访问焊接实例中的注射bean时，我会得到一个空指针异常。在野生蝇实例上，我没有问题。部署期间没有错误。

我在所有罐子中都有一个beans.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee    http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
   bean-discovery-mode="all">
</beans>

我使用的是焊接核3.0.2.final。Java版本" 1.8.0_121" AbstractConnection和ExecutorImpl在同一软件包和JAR文件中。RiteXecutor接口在另一个JAR文件中。

我已经升级到焊接3.0.3.3，并尝试了没有机会的应用程序注释。

这是我的测试场景。PostConstruct在选择bean上正常工作。

````

package org.dpp.cdi.singleton;
import java.util.logging.Logger;
import javax.annotation.PostConstruct;
import javax.enterprise.inject.se.SeContainer;
import javax.enterprise.inject.se.SeContainerInitializer;
import javax.inject.Singleton;
import org.jboss.weld.environment.se.Weld;
/**

 * @author mochieng
 */
public class TestMain {
    public static void main(String[] args) {
        SeContainerInitializer weld = Weld.newInstance();
        try (SeContainer se = weld.disableDiscovery().addBeanClasses(TestServiceImpl.class).initialize()) {
            TestService service = se.select(TestService.class).get();
        }
    }
    public static interface TestService {
        void doTest();
    }
    @Singleton
    public static class TestServiceImpl implements TestService {
        private static final Logger LOG = Logger.getLogger(TestServiceImpl.class.getName());
        @PostConstruct
        void initImpl() {
            LOG.info("Initialized singleton");
        }
        @Override
        public void doTest() {
            LOG.info("Singleton called");
        }
    }
}

和maven依赖性：

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>org.dpp</groupId> <artifactId>cdi-singleton</artifactId> <version>1.0.0-SNAPSHOT</version> <packaging>jar</packaging> <dependencies> <dependency> <groupId>org.jboss.weld.se</groupId> <artifactId>weld-se-shaded</artifactId> <version>3.0.3.Final</version> </dependency> </dependencies> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> </project>

问题可能是您的焊接版本。
