Spring Jackson support has been improved lately to be more flexible and powerful. This blog post gives you an update about the most useful Jackson related features available in Spring Framework 4.x and Spring Boot. All the code samples are coming from this spring-jackson-demo sample application, feel free to have a look at the code. JSON View If we are using spring boot for application development then we can configure spring. jackson. property-naming-strategy with naming strategy inside application.properties or application.yml. or without spring boot application or spring MVC application, we can register bean of Jackson2ObjectMapperBuilder and define configuration related to naming strategy

2. Spring Jackson exclude null fields 1. Spring Jackson exclude null field level @JsonInclude(JsonInclude.Include.NON_NULL) configuration at the field level, If the field contains NULL value then it will exclude that field from JSON. @JsonInclude(JsonInclude.Include.NON_NULL) for excluding NULL value Crucially, this means that you've disabled the logic which applies your spring.jackson.* configuration to the _halObjectMapper bean. Removing this annotation will mean that the configuration takes effect. You should also get rid of your ObjectMapper and JodaModule beans and allow Boot to automatically configure them for you. With these three changes your sample app produces this output: {date. Java-based configuration option enables you to write most of your Spring configuration without XML but with the help of few Java-based annotations explained in this chapter. @Configuration & @Bean Annotations. Annotating a class with the @Configuration indicates that the class can be used by the Spring IoC container as a source of bean definitions. The @Bean annotation tells Spring that a. This POM configuration will override the Jackson dependencies set in the Spring Boot parent POM. This post is specific to Spring Boot version 1.3.3.
