OneOf

This validator is useful to perform a check that a provided string is in a list of string or sentence Follwing an example

public class OneOfBean {

    @OneOf(options = {"Hello", "World", "Hey Joe!"})
    String value;

    public OneOfBean(String value) {

        this.value = value;
    }
}

As you can see the string value is annotated with @NOneOf indicating the list of word (or sentences) that should be equals to.

You can change the default message as in the following example:

public class OneOfBeanV2 {

    @OneOf(options = {"Hello", "World", "Hey Joe!"}, message = "Are you sure?")
    String value;

    public OneOfBeanV2(String value) {

        this.value = value;
    }
}

There is also an option to ignore the case of the provided string. With this option set to false (the default) the check will fail if the provided string is not in the correct case

public class OneOfBeanV2 {

    @OneOf(options = {"Hello", "World", "Hey Joe!"}, ignoreCase = true)
    String value;

    public OneOfBeanV2(String value) {

        this.value = value;
    }
}
