MongoDB Client, Java

Def

This is a simple client for MongoDB. I use it in my projects.

Example

try (Mongo<RapnetDocument> mongo = new Mongo<>(RapnetDocument.class)) {
    //find source
    Bson projectionFields = Projections.fields(
            Projections.include("createDate"));
    Bson sort = Sorts.descending("createDate");
    MongoSelectQuery queryLastDoc = MongoSelectQuery.builder()
            .projection(projectionFields)
            .sort(sort)
            .limit(1)
            .build();
    List<RapnetDocument> resultList = mongo.executeSelect(queryLastDoc);
    RapnetDocument expected = resultList.get(0);

    //update source
    LocalDateTime date = LocalDateTime.now();
    expected.setCreateDate(date);
    UpdateResult updateResult = mongo.executeUpdateDoc(expected);
    System.out.println("Update Result: " + updateResult);

    //assert changes
    MongoSelectQuery queryExpectedDoc = MongoSelectQuery.builder()
            .filter(eq("_id", expected.getId()))
            .build();
    RapnetDocument actual = mongo.executeSelect(queryExpectedDoc).get(0);
    assertThat("expected is actual", expected, is(actual));
}
