是否可以使用XCC查询Marklogic而无需使用＆＃39; AdhocQuery＆＃39;

Question

任何人都试图使用XCC java类连接到Marklogic - 我想连接并进行查询但不使用＆＃39; adhocquery＆＃39; （xquery） - 这可能吗？使用XCC Session或Request类？

Answer 1

您可以使用请求调用模块，而不是执行adhocQuery。newModuleInvoke()

String connectionUri = "xcc://user:password@localhost:8888";
String moduleUri = "/some/module.xqy";

ContentSource contentSource = ContentSourceFactory.newContentSource(connectionUri);   
ResultSequence resultSequence = null;

try (Session session = contentSource.newSession()) {
  Request request = session.newModuleInvoke(moduleUri);
  /*
   *if you need to set request parameters, look at the setXXXVariable methods
   * https://docs.marklogic.com/javadoc/xcc/com/marklogic/xcc/Request.html
   * i.e.
   * request.setNewStringVariable("foo", "bar");
   * request.setVariable(xdmVariable); //see also: ValueFactory.newVariable()
   */ 
  resultSequence = session.submitRequest(request);

  //do stuff with the result sequence

} catch (RequestException exc) { 
    //Determine if the exception is retryable or should fail 
} catch (Exception exc) { 
    //Determine what to do with other exceptions 
} finally { 
    //unfortunately, ResultSequence doesn't implement closable...
    if (null != resultSequence && !resultSequence.isClosed()) { 
      resultSequence.close(); 
      resultSequence = null; 
    } 
}
