Generation of XSD restrictions in a schema generated from Java JAXB annotated classes

Question

MOXy BeanValidation gives me the ability to add validation to my JAXB classes.

Using MOXy\'s \"Bean Validation Plugin\" I can have Bean Validation in generated JAX

Answer 1

You could also look to xjc plugin https://github.com/krasa/krasa-jaxb-tools

By documentation it support XJsr303Annotations and can generate:

• @Valid annotation for all complex types, can be further restricted to generate only for types from defined schema: -XJsr303Annotations:targetNamespace=http://www.foo.com/bar
• @NotNull annotation for objects that has a MinOccur value >= 1 or for attributes with required use
• @Size for lists that have minOccurs > 1
• @Size if there is a maxLength or minLength or length restriction
• @DecimalMax for maxInclusive restriction
• @DecimalMin for minInclusive restriction
• @DecimalMax for maxExclusive restriction, enable new parameter (inclusive=false) with: -XJsr303Annotations:JSR_349=true
• @DecimalMin for minExclusive restriction, enable new parameter (inclusive=false) with: -XJsr303Annotations:JSR_349=true
• @Digits if there is a totalDigits or fractionDigits restriction.
• @Pattern if there is a Pattern restriction

If you wonder how to use XJC plugins in your build environment (ant, maven, gradle) I may recomment look at examples of another plugin: immutable-xjc

So I hope it helps.
