[[MongoDBGridFS-ConfigurationofdatabaseinSpringXML]]
Configuration of database in Spring XML
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The following Spring XML creates a bean defining the connection to a
MongoDB instance.
[source,xml]
----------------------------------------------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------------------------------------------
[[MongoDBGridFS-Sampleroute]]
Sample route
^^^^^^^^^^^^
The following route defined in Spring XML executes the operation
link:mongodb-gridfs.html[*findOne*] on a collection.
*Get a file from GridFS*
[source,xml]
----------------------------------------------------------------------------------
----------------------------------------------------------------------------------
??
[[MongoDBGridFS-GridFSoperations-producerendpoint]]
GridFS operations - producer endpoint
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[[MongoDBGridFS-count]]
count
+++++
Returns the total number of file in the collection, returning an Integer
as the OUT message body. +
+
[source,java]
---------------------------------------------------------------------------------
// from("direct:count").to("gridfs?database=tickets&operation=count");
Integer result = template.requestBodyAndHeader("direct:count", "irrelevantBody");
assertTrue("Result is not of type Long", result instanceof Integer);
---------------------------------------------------------------------------------
You can provide a filename header to provide a count of files matching
that filename.
[source,java]
-------------------------------------------------------------------------------
Map headers = new HashMap();
headers.put(Exchange.FILE_NAME, "filename.txt");
Integer count = template.requestBodyAndHeaders("direct:count", query, headers);
-------------------------------------------------------------------------------
[[MongoDBGridFS-listAll]]
listAll
+++++++
Returns an Reader that lists all the filenames and their IDs in a tab
separated stream.
[source,java]
----------------------------------------------------------------------------------
// from("direct:listAll").to("gridfs?database=tickets&operation=listAll");
Reader result = template.requestBodyAndHeader("direct:listAll", "irrelevantBody");
filename1.txt 1252314321
filename2.txt 2897651254
----------------------------------------------------------------------------------
??
[[MongoDBGridFS-findOne]]
*findOne*
+++++++++
Finds a file in the GridFS system and sets the body to an InputStream of
the content. ?? Also provides the metadata has headers. ??It uses
Exchange.FILE_NAME from the incoming headers to determine the file to
find.
[source,java]
-------------------------------------------------------------------------------------------------
// from("direct:findOne").to("gridfs?database=tickets&operation=findOne");
Map headers = new HashMap();
headers.put(Exchange.FILE_NAME, "filename.txt");
InputStream result = template.requestBodyAndHeaders("direct:findOne", "irrelevantBody", headers);
-------------------------------------------------------------------------------------------------
??
[[MongoDBGridFS-create]]
create
++++++
Creates a new file in the GridFs database. It uses the
Exchange.FILE_NAME from the incoming headers for the name and the body
contents (as an InputStream) as the content.
[source,java]
------------------------------------------------------------------------
// from("direct:create").to("gridfs?database=tickets&operation=create");
Map headers = new HashMap();
headers.put(Exchange.FILE_NAME, "filename.txt");
InputStream stream = ... the data for the file ...
template.requestBodyAndHeaders("direct:create", stream, headers);
------------------------------------------------------------------------
[[MongoDBGridFS-remove]]
remove
++++++
Removes a file from the GridFS database.
[source,java]
------------------------------------------------------------------------
// from("direct:remove").to("gridfs?database=tickets&operation=remove");
Map headers = new HashMap();
headers.put(Exchange.FILE_NAME, "filename.txt");
template.requestBodyAndHeaders("direct:remove", "", headers);
