osgi異常在Activator.start（）

我新開始osgi我的代碼運行的是java應用程序，但它沒有運行osgi，錯誤原因是'import com.sun.codemodel'如何解決這個問題。osgi異常在Activator.start（）

我的激活器類爲：

package deneme; 

import java.io.File; 
import java.net.URL; 

import org.jsonschema2pojo.SchemaMapper; 
import org.osgi.framework.BundleActivator; 
import org.osgi.framework.BundleContext; 

import com.sun.codemodel.JCodeModel; 

public class Activator implements BundleActivator { 

    /* 
    * (non-Javadoc) 
    * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext) 
    */ 
    public void start(BundleContext context) throws Exception { 
     System.out.println("Hello World!!"); 
     String workingDir = System.getProperty("user.dir"); 

     JCodeModel codeModel = new JCodeModel(); 
     try { 
      URL sourceRota = new URL("file:///C:/Users/Administrator/workspace/NavsimKisa/rota_yeni.json"); 
      URL sourceKriter = new URL("file:///C:/Users/Administrator/workspace/NavsimKisa/kriter_yeni.json"); 
      URL sourceSabit = new URL("file:///C:/Users/Administrator/workspace/NavsimKisa/sabit_yeni.json"); 

      new SchemaMapper().generate(codeModel, "ClassNameRota", "Rota.entity", sourceRota); 
      new SchemaMapper().generate(codeModel, "ClassNameKriter", "Kriter.entity", sourceKriter); 
      new SchemaMapper().generate(codeModel, "ClassNameSabit", "Sabit.entity", sourceSabit); 

      codeModel.build(new File(workingDir + "/src/main/java")); 
     } catch (Exception e) { 
      // TODO: handle exception 
     } 

    } 

    /* 
    * (non-Javadoc) 
    * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext) 
    */ 
    public void stop(BundleContext context) throws Exception { 
     System.out.println("Goodbye World!!"); 
    } 

}

我的錯誤：

my error is :Hello World!!

您首先需要導出包com.sun.codemodel在系統中捆綁。這由框架屬性org.osgi.framework.system.packages.extra完成。

然後，您需要確保您自己的包使用Manifest中的Import-Package定義導入。

希望您使用的庫不會與類加載器混淆，那麼它應該可以正常工作。
