From my pom:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</dependency>
While creating the org.springframework.web.client.RestTemplate object I am getting this exception
How do I fix this?

Answer 1

com.fasterxml.jackson.dataformat.xml.XmlMapper is from an optional Jackson extension (https://github.com/FasterXML/jackson-dataformat-xml). You can include it in your project by adding the following to the pom:
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
In case the version for this Maven artifact is not defined in the parent pom, you must add it yourself, e.g. for the latest version
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.10.1</version>
</dependency>
You may need more dependencies, so check the link from above.
