| = Validation |
| |
| == Programmatic |
| |
| Use the https://github.com/apache/fineract/search?q=%22class+DataValidatorBuilder%22[DataValidatorBuilder], e.g. like so: |
| |
| [source,java] |
| ---- |
| new DataValidatorBuilder().resource("fileUpload") |
| .reset().parameter("Content-Length").value(contentLength).notBlank().integerGreaterThanNumber(0) |
| .reset().parameter("FormDataContentDisposition").value(fileDetails).notNull() |
| .throwValidationErrors(); |
| ---- |
| |
| Such code is often encapsulated in https://github.com/apache/fineract/search?q=Validator[`*Validator`] classes (if more than a few lines, and/or reused from several places; avoid copy/paste), like so: |
| |
| [source,java] |
| ---- |
| public class YourThingValidator { |
| |
| public void validate(YourThing thing) { |
| new DataValidatorBuilder().resource("yourThing") |
| ... |
| .throwValidationErrors(); |
| } |
| } |
| ---- |
| |
| |
| == Declarative |
| |
| https://issues.apache.org/jira/browse/FINERACT-1229[FINERACT-1229] is an open issue about adopting Bean Validation for _declarative_ instead of _programmatic_ (as above) validation. Contributions welcome! |
