The invention provides a deserialization method and apparatus. The method comprises the steps of obtaining a piece of serialization data, wherein the serialization data comprises a first attribute of a to-be-reconstructed object; analyzing the serialization data to generate a first key value pair, wherein the first key value pair comprises first key information and first value information, and the first key information and the first value information have a corresponding relationship; and according to a preset corresponding relationship between the first key information and the first attribute, assigning the first value information, corresponding to the first key information, to the first attribute. According to the method and the apparatus, the attribute of the to-be-reconstructed object does not need to be obtained by reflection, so that excessive hardware resources do not need to be occupied and the deserialization efficiency is improved.
