Question

我在JAVA项目中使用此SSRS-API，使用SQL Server Reporting Services。使用此API，我可以访问我的SSRS文件夹和报告，但我想知道是否可以上传或导出Excel或PDF格式的报告。

这是SSRS java类：SSRS.java

我的托管豆：

@ViewScoped
@ManagedBean(name = "biController")
@SuppressWarnings("restriction")
public class BiController {

    private final String ADDRESS = "http://SERVERNAME/reportserver/ReportService2005.asmx?wsdl";
    private String[] listReports;
    private SSRS ssrs;

    @PostConstruct
    public void init() {
        try {
            URL url = new URL(null, ADDRESS, new sun.net.www.protocol.http.Handler());
            NTLMAuthenticator.setDefault(new NTLMAuthenticator("DOMAIN", "USERNAME", "PASSWORD"));
            ssrs = new SSRS(url, "");
        } catch (MalformedURLException e) {
            throw new FacesException();
        }
    }

    // This function let me have the Report's names
    public void constructListOfReports(String path) {
        listReports = ssrs.listReports(path);
    }

    public String[] getListReports() {
        return listReports;
    }

    public void setListReports(String[] listReports) {
        this.listReports = listReports;
    }

}

有什么建议吗？

我使用了上面提到的SSRS api的下载功能（ downloadReport ）（SSRS-API），这是函数的代码：

public void downloadReport(final String path, final String filename) {
    final File file = new File(filename);
    final String physicalName = toPhysicalFileName(path);

    info("Downloading Report with symbolic name " + path + " to " + file);

    final byte[] data = _soap.getReportDefinition(physicalName);

    try (final FileOutputStream out = new FileOutputStream(file)) {
        out.write(data);
    } catch (final IOException ioe) {
        final String message = "Failed to download report with symbolic name " + path + " to " + file;
        LOG.warning(message);
        if (file.exists() && !file.delete()) {
            throw new IllegalStateException(message + " and failed to delete temporary file", ioe);
        } else {
            throw new IllegalStateException(message, ioe);

        }
    }
}

这是我用来调用这个函数的函数：

public void downloadReport() {
    ssrs.downloadReport('Path/Report name', 'C:\\PATH\\TO\\A\\FOLDER\\REPORT.XML');
}

在给定的路径（C：/PATH/TO/A/FOLDER/REPORT.XML）中，我得到一个这样的XML文件：

Answer 1

我通过生成带URL的报告解决了这个问题，这是允许我生成报告的功能：

public void downloadReportExcel(String path) {
    try {
        String url = "http://" + SSRS_IP + "/ReportServer?/" + path + "&rs:Format=Excel";

        FacesContext.getCurrentInstance().getExternalContext().redirect(url);

        return;
    } catch (IOException e) {
        throw new FacesException(e);
    }
}

该函数在参数中获取路径并将我重定向到具有2个参数的服务器URL：

？/ path：是要生成的报告的完整路径（来自根文件夹）
rs：Format = Excel：是生成的格式（这里我想将报告导出到Excel，但它可以采用PDF，如：＆amp; rs：Format = PDF）

SSRS使用SOAP in Java上载报告
