给我用Java写一个dcm4che cstore demo

在Java中，你可以使用dcm4che库来实现DICOM的C-STORE（存储）操作。以下是一个简单的示例，展示如何使用`org.dcm4che3.data.DataSource`来发送DICOM文件到一个远程SCP服务器：

import org.dcm4che3.data.DataSource;
import org.dcm4che3.net.AAssociateRQ;
import org.dcm4che3.net.ActiveAssociation;
import org.dcm4che3.net.ApplicationEntity;
import org.dcm4che3.net.DicomServiceException;
import org.dcm4che3.net.PDU;
import org.dcm4che3.net.TCPUtils;

public class CStoreDemo {
    public static void main(String[] args) throws Exception {
        // SCP服务器的信息
        String host = "your_scp_host";
        int port = your_scp_port;
        String aet = "your_aetitle";

        // DICOM文件路径
        String filePath = "/path/to/your/dicom/file.dcm";

        // 创建DataSource对象
        DataSource ds = DataSource.file(filePath);

        try (ActiveAssociation assoc = Association.connect(host, port, aet, ApplicationEntity.CS_DIR_US)) {
            if (!assoc.isAccepted()) {
                System.out.println("Association rejected");
                return;
            }

            // 发送C-STORE请求
            PDU request = new StoreRequest(ds);
            PDU response = assoc.send(request);

            if (response instanceof CStoreACK || response instanceof CStorePending) {
                System.out.println("C-STORE operation was successful");
            } else {
                throw new DicomServiceException("Unexpected response: " + response);
            }
        } catch (DicomServiceException e) {
            System.err.println("Error sending C-STORE: " + e.getMessage());
        }
    }
}

在这个例子中，你需要替换`your_scp_host`、`your_scp_port`和`your_aetitle`为实际的SCP服务器详细信息。注意，此代码片段仅做演示，生产环境使用时需添加适当的错误处理和资源管理。
