java - JasperServer REST 客户端路径如何？

Question

我正在努力使用 jasperserver 提供客户端休息服务来生成报告。我使用以下代码来实现:

我在设置服务器 URL 和报告路径时遇到问题，对于服务器网址，我输入 http://localhost:8081/jasperserver/如下图所示，我放置了报告路径 rest/report/mytest/my_report 但我在行中收到 404 not found 错误

File remoteFile = resource.get(File.class);

那么如何从 jasperserver 获取正确的报告路径？

public class App2 {

private final static String serverUrl = "http://localhost:8081
   /jasperserver/";
private final static String serverUser = "jasperadmin";
private final static String serverPassword = "jasperadmin";

public static void main(String arg[]) throws Exception {
    Report reporte = new Report();
    reporte.setFormat("pdf");
    reporte.setOutputFolder("/home/ali/images");
    ClientConfig clientConfig;
    Map<String, String> resourceCache=new HashMap<String, String>();
    clientConfig = new DefaultApacheHttpClientConfig();
    clientConfig.getProperties().put(ClientConfig.PROPERTY_FOLLOW_REDIRECTS, true);
    clientConfig.getProperties().put(ApacheHttpClientConfig.PROPERTY_HANDLE_COOKIES, true);
    ApacheHttpClient client = ApacheHttpClient.create(clientConfig);
    client.addFilter(new HTTPBasicAuthFilter(serverUser, serverPassword));
    String describeResourcePath = "/rest/resource" + "/mytest/my_report/";
    String generateReportPath = "/rest/report" + "/mytest/my_report/" + "?RUN_OUTPUT_FORMAT=" + reporte.getFormat();
    WebResource resource = null;
    String resourceResponse = null;
    if (resourceCache.containsKey(describeResourcePath)) {
        resourceResponse = resourceCache.get(describeResourcePath);
    } else {
        resource = client.resource(serverUrl);
        resource.accept(MediaType.APPLICATION_XML);
        resourceResponse = resource.path(describeResourcePath).get(String.class);
        resourceCache.put(describeResourcePath, resourceResponse);
    }
    Document resourceXML = parseResource(resourceResponse);
    resourceXML = addParametersToResource(resourceXML, reporte);
    resource = client.resource(serverUrl  + generateReportPath);
    resource.accept(MediaType.TEXT_XML);
    System.out.println(resource);
    String reportResponse = resource.put(String.class, serializetoXML(resourceXML));
    String urlReport = parseReport(reportResponse);
    resource = client.resource(urlReport);
    System.out.println(resource);
    File destFile = null;
    try {
        File remoteFile = resource.get(File.class);
        File parentDir = new File(reporte.getOutputFolder());
        destFile = File.createTempFile("report_", "." + getExtension(reporte.getFormat()), parentDir);
        FileUtils.copyFile(remoteFile, destFile);
    } catch (IOException e) {
        throw e;
    }

我已经修复了它，我需要更改路径

urlReport = serverUrl + "/report/" + uuid + "?file=report"; 

至

urlReport = serverUrl + "/rest/report/" + uuid + "?file=report";

在parseReport方法中

private static String parseReport(String reportResponse) throws Exception {
String urlReport = null;
try {
    Document document = DocumentHelper.parseText(reportResponse);
    Node node = document.selectSingleNode("/report/uuid");
    String uuid = node.getText();
    node = document.selectSingleNode("/report/totalPages");
    Integer totalPages = Integer.parseInt(node.getText());
    if (totalPages == 0) {
        throw new Exception("Error generando reporte");
    }
    urlReport = serverUrl + "/report/" + uuid + "?file=report";
} catch (DocumentException e) {
    throw e;
}
return urlReport;

}
