Question

我在使用mongodb方面还很陌生。到目前为止，我真的很喜欢和mongogbb合作。但是，我很难使mongodb验证正常工作。在文档中，有一个很好的示例来实现上述验证。

db.createCollection("students", {
   validator: {
      $jsonSchema: {
         bsonType: "object",
         required: [ "name", "year", "major", "gpa" ],
         properties: {
            name: {
               bsonType: "string",
               description: "must be a string and is required"
            },
            gender: {
               bsonType: "string",
               description: "must be a string and is not required"
            },
            year: {
               bsonType: "int",
               minimum: 2017,
               maximum: 3017,
               exclusiveMaximum: false,
               description: "must be an integer in [ 2017, 3017 ] and is required"
            },
            major: {
               enum: [ "Math", "English", "Computer Science", "History", null ],
               description: "can only be one of the enum values and is required"
            },
            gpa: {
               bsonType: [ "double" ],
               minimum: 0,
               description: "must be a double and is required"
            }
         }
      }
   }
})

上面提到的示例我尝试使用mongo-java-driver 3.3.0实现

 public PlayerCrudManager(String collection) {
        super(collection);
        /** Create validation schema */
        Bson forename = Filters.type("forename", BsonType.STRING);
        Bson surname = Filters.type("surname", BsonType.STRING);
        Bson email = Filters.regex("email", "@*.*$");
        Bson password = Filters.type("passwordHash", BsonType.STRING);
        Bson biography = Filters.type("biography", BsonType.STRING);
        Bson nickname = Filters.type("nickname", BsonType.STRING);
        Bson lokSafe = Filters.type("lokSafe", BsonType.BOOLEAN);
        Bson captureQuickly = Filters.type("captureQuickly", BsonType.BOOLEAN);
        Bson image = Filters.type("image", BsonType.STRING);
        Bson timeStamp = Filters.type("timestamp", BsonType.TIMESTAMP);
        Bson validator = Filters.and(forename, surname, email, password, biography, nickname, lokSafe, captureQuickly, image, timeStamp);
        ValidationOptions validationOptions = new ValidationOptions().validator(validator);
        super.getDb().createCollection(collection, new CreateCollectionOptions().validationOptions(validationOptions));

    }

不幸的是，我想为每个属性实现描述，因为我希望能从mongo收到响应，指出哪个字段导致了失败。我理解这个描述标签对吗？使思路清晰。我的主要目标是在mongo中插入任何json并在列出错误字段的地方获得响应。
