I am developing Spring Boot + Batch project and reading data from the xls file and while reading data I am getting below error.

I've already added the xstream version 1.4.11.1 and Spring OXM dependency still, its giving the error. Boot Version is 2.1.1.RELEASE.

Error:

I faced the same problem doing the same thing.

I found a solution at mkyong.com that worked for me.

The class DefaultConverterLookup belongs to xstream.jar. And you need to add the following dependency in your pom.xml or whatever the dependency management you're using.

<dependency>
    <groupId>com.thoughtworks.xstream</groupId>
    <artifactId>xstream</artifactId>
    <version>1.4.11.1</version>
</dependency>
