Question 2: Is any one able to shed any light on how this annotation was broken in JDK 9 and why lombok now considers it undesirable to generate this annotation by default anymore. The absolute simplest way of working with this is to just use the default configuration: However, if we need additional configuration, we can instead construct the Jackson Module manually and set it up as necessary: As of version 2.9.0, the only configuration options for the XML Module are: Due to the fact that the XmlMapper extends the standard ObjectMapper, we can essentially use all of the standard Jackson ObjectMapper configuration settings and APISs. It's common that when we use builders the constructors of our classes are private and instances can only be created through the builder. @JacksonXmlPropertycan be applied to any field in a bean to control the details of the element that is being rendered. He is an excellent resource to our site personnel to help mitigate challenges and provide guidance as needed. This last requirement sounds like its conflicting with the earlier requirement that the data model must be immutable, but Ill show how to achieve both in the next sections.

Find centralized, trusted content and collaborate around the technologies you use most. property being used for binding data to be passed as that parameter Does it mean that if I set lombok.anyConstructor.addConstructorProperties=true I am gonna hit the same problem as soon as I migrate to Java 9 or not? If we want to use another one we have to specify it in the buildMethodName property of the @JsonPOJOBuilder annotation as we did in the previous section. Example 2 does not work because Jackson does not find a usable constructor (because it cannot map the field names to the parameter names of the only existing constructor, as these names are not present at runtime). In this quick tutorial, were going to highlight Lombok constructor annotations and explore in detail how each one works under-the-hood. Deserialisation (surprisingly, at least to me) seems to work. annotation so Jackson doesn't know how to deserialize the data into an According to the docs, a required argument is a field declared final or has some constraints such as @NonNull.
