java - 将 Java SE 应用程序打包到可执行 Jar 中

Question

我在尝试从命令行运行 JAVA SE 可执行 jar 时遇到以下异常:

但是，我能够在 Eclipse 中成功运行该程序，但一旦打包到 jar 中，我总是会遇到此错误。

这是我的 Maven 包插件:

     <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>single</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
      </plugin>
 <!-- Build an executable JAR -->
    <plugin>
      <!-- Build an executable JAR -->
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-jar-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <addClasspath>true</addClasspath>
            <classpathPrefix>lib/</classpathPrefix>
            <mainClass>org.jboss.weld.environment.se.StartMain</mainClass>
          </manifest>
        </archive>
      </configuration>
    </plugin>
    </plugins>

这是我引导 Weld 的方法:

public  static void main(String[] args) {
    //Start CDI container
    WeldContainer weldContainer = WeldFactory.INSTANCE.getWeldContainer();

    try {
        MainThread mainExecutor = weldContainer.instance().select(MainThread.class).get(); 
        mainExecutor.run();
    } catch (Exception e) {
        LOG.error("Fatal error",e);
    }finally {
        //Shutdwon CDI container
        weldContainer.shutdown();   
    }

}

//  @Inject
//  MainThread mainExecutor;
//  
//    public void main(@Observes ContainerInitialized event){
//      try {
//          //MainThread mainExecutor = weldContainer.instance().select(MainThread.class).get(); 
//          mainExecutor.run();
//      } catch (Exception e) {
//          LOG.error("Fatal error",e);
//      }finally {
//          //Shutdwon CDI container
//          //weldContainer.shutdown(); 
//      }
//
//    }

(我尝试了注释和未注释的代码，但仍然遇到相同的错误)。任何帮助都会很棒，我真的尝试了所有方法。

用户 Siliarus 帮助了您，为他点赞。

现在您遇到了另一个问题。应用程序立即关闭。
这并不奇怪 - 发生这种情况是因为您没有使用 ContainerInitialized事件。如果您使用的是内置org.jboss.weld.environment.se.StartMain类，那么你应该有一个简单的 bean 来观察 ContainerInitialized事件。

或者，您可以使用您在上面粘贴的内容 Main 类。为此，请指示 maven-jar-plugin使用 main 来使用你的 Shiny 类方法如下:

<mainClass>com.your.own.class.with.main.method</mainClass>

如果遇到其他问题，我鼓励您查看 Weld 用法的工作示例:https://github.com/weld/core/tree/master/examples .

希望有帮助。
