windchill BOM结构复制api

Windchill BOM结构复制API可以使用Windchill Java API来实现，以下是一个简单的示例代码：

import wt.fc.PersistenceHelper;
import wt.fc.QueryResult;
import wt.fc.WTObject;
import wt.inf.container.WTContainer;
import wt.inf.container.WTContainerRef;
import wt.part.WTPart;
import wt.part.WTPartMaster;
import wt.part.WTPartUsageLink;
import wt.session.SessionHelper;
import wt.util.WTException;

public class BOMCopyUtil {

    /**
     * 复制BOM结构
     *
     * @param sourcePartMaster 源部件Master
     * @param targetPartMaster 目标部件Master
     * @throws WTException
     */
    public static void copyBOMStructure(WTPartMaster sourcePartMaster, WTPartMaster targetPartMaster) throws WTException {
        // 获取源部件的使用关系
        QueryResult sourceUsageLinks = WTPartHelper.service.getUsesWTPartMasters(sourcePartMaster);
        // 遍历源部件的使用关系
        while (sourceUsageLinks.hasMoreElements()) {
            WTPartUsageLink sourceUsageLink = (WTPartUsageLink) sourceUsageLinks.nextElement();
            // 获取源部件的子件Master
            WTPartMaster sourceChildPartMaster = sourceUsageLink.getUses();
            // 创建目标部件的子件
            WTPart targetChildPart = createPart(sourceChildPartMaster, targetPartMaster);
            // 创建目标部件和子件的使用关系
            createUsageLink(targetPartMaster, targetChildPart);
            // 递归复制子部件的BOM结构
            copyBOMStructure(sourceChildPartMaster, targetChildPart.getMaster());
        }
    }

    /**
     * 创建部件
     *
     * @param sourcePartMaster 源部件Master
     * @param targetPartMaster 目标部件Master
     * @return 目标部件
     * @throws WTException
     */
    private static WTPart createPart(WTPartMaster sourcePartMaster, WTPartMaster targetPartMaster) throws WTException {
        // 创建目标部件
        WTPart targetPart = WTPart.newWTPart(targetPartMaster);
        // 设置目标部件的属性
        targetPart.setName(sourcePartMaster.getName());
        targetPart.setNumber(sourcePartMaster.getNumber());
        targetPart.setDescription(sourcePartMaster.getDescription());
        // 复制源部件的图片
        targetPart.setThumbnail(sourcePartMaster.getThumbnail());
        // 添加目标部件到目标容器
        WTContainerRef targetContainerRef = targetPartMaster.getContainerReference();
        WTContainer targetContainer = targetContainerRef.getContainedContainer();
        targetContainer.add(targetPart);
        PersistenceHelper.manager.save(targetPart);
        return targetPart;
    }

    /**
     * 创建使用关系
     *
     * @param parentPartMaster 父部件Master
     * @param childPart        子部件
     * @throws WTException
     */
    private static void createUsageLink(WTPartMaster parentPartMaster, WTPart childPart) throws WTException {
        // 创建使用关系
        WTPartUsageLink usageLink = new WTPartUsageLink(parentPartMaster, childPart.getMaster());
        // 添加使用关系到父部件Master
        parentPartMaster.addUses(usageLink);
        PersistenceHelper.manager.save(parentPartMaster);
    }
}

使用方法：

// 获取源部件Master
WTPartMaster sourcePartMaster = (WTPartMaster) PersistenceHelper.manager.refresh(sourcePart);
// 获取目标部件Master
WTPartMaster targetPartMaster = (WTPartMaster) PersistenceHelper.manager.refresh(targetPart);
// 复制BOM结构
BOMCopyUtil.copyBOMStructure(sourcePartMaster, targetPartMaster);

其中，sourcePart和targetPart是源部件和目标部件的对象。请注意，该示例代码只能复制BOM结构，不能复制零部件的CAD文档等其他相关数据。
