Jackson ObjectMapper - specify serialization order of object properties

The annotations are useful, but can be a pain to apply everywhere. You can configure your whole ObjectMapper to work this way with

Current Jackson versions:

objectMapper.configure(MapperFeature.SORT_PROPERTIES_ALPHABETICALLY, true)

Older Jackson versions:

objectMapper.configure(SerializationConfig.Feature.SORT_PROPERTIES_ALPHABETICALLY, true);

From the Jackson Annotations documentation:

// ensure that "id" and "name" are output before other properties
@JsonPropertyOrder({ "id", "name" })

// order any properties that don't have explicit setting using alphabetic order
@JsonPropertyOrder(alphabetic=true)
