Apache Camel - Data Mapping Ideas Scattered Over the Net

Apache Camel - Data Mapping Ideas Scattered Over the Net.md

• Small example to show a solution for your use-case with mixins:

class Data {
    int totalUsers;
    int totalBooks;
}

class DataMixin {
    @JsonProperty("Total Users")
    int totalUsers;
    @JsonProperty("Total Books")
    int totalBooks;
}

// Jackson 2.5+

ObjectMapper mapper = new ObjectMapper();
if (pretty) {
    mapper.addMixin(Data.class, DataMixin.class);
}

• To be added on pom.xml when using jackson?

Class or .java:

import com.fasterxml.jackson.annotation.JsonProperty;

pox.xml

  <!--jackson for pom.xml -->
	<dependency>
	    <groupId>com.fasterxml.jackson.core</groupId>
	    <artifactId>jackson-core</artifactId>
	    <version>2.11.1</version><!--$NO-MVN-MAN-VER$-->
	</dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.dataformat</groupId>
        <artifactId>jackson-dataformat-xml</artifactId>
        <version>2.11.1</version><!--$NO-MVN-MAN-VER$-->
    </dependency>
