v0.5.0

Breaking Change: The build.buf.protovalidate.ValidationResult.getViolations() method no longer returns a list of protobuf build.buf.validate.Violations messages, but a list of a new wrapper class, build.buf.protovalidate.Violation. In most cases, changing the import for Violation and calling the toProto() method of the violation is all that needs to be done:

     // Note that the import should also change from `build.buf.validate.Violation`
     // to `build.buf.protovalidate.Violation`.
     for (Violation violation : validator.validate(msg).getViolations()) {
-        System.out.println(violation.getConstraintId());
+        System.out.println(violation.toProto().getConstraintId());
     }

ValidationResult also has a toProto() method that returns the protobuf build.buf.validate.Violations message equivalent. This can be used to get a list of protobuf build.buf.validate.Violation messages, using the getViolationsList() getter of said message, as before.

+    List<build.buf.validate.Violation> violations = validator.validate(msg).getViolations();
-    List<build.buf.validate.Violation> violations = validator.validate(msg).toProto().getViolationsList();

---

The new build.buf.protovalidate.Violation class provides additional getters for in-memory information about the violation which cannot be serialized to the wire:

• getFieldValue(): Returns the value of the field failing validation, if there is a field corresponding to the violation.
• getRuleValue(): Returns the value of the rule failing validation, if there is a rule corresponding to the violation.

Take, for example, the following protobuf message schema:

message User {
    string email = 1 [(buf.validate.field).string.email = true];
}

If you try to validate the message User.newBuilder().setEmail("invalid").build(), getFieldValue().getValue() will return "invalid" and getRuleValue().getValue() will return true.

Some violations do not correspond directly to a field, such as a message constraint failure; in these cases, the return value of getFieldValue() will be null.

v0.4.0

Adds support for custom predefined field constraints. See the protovalidate documentation for more information.

Updates protovalidate to v0.8.1. Note that this is a breaking change. You may need to make some adjustments to your code:

• Code that imports build.buf.validate.ExpressionProto or build.buf.validate.priv.PrivateProto should now only import build.buf.validate.ValidateProto.
• build.buf.validate.priv.PrivateProto.field was moved to build.buf.validate.ValidateProto.predefined

What's Changed

• Implement predefined field constraints by @jchadwick-buf in #178

v0.3.0

Note

This release updates protovalidate-java to use Protobuf Java v4+, which is not currently completely compatible with Protobuf Java v3 gencode. If you can not upgrade to Protobuf Java v4 currently, you should continue to use protovalidate-java v0.2.1 or lower for now. A future release of Protobuf Java v4.27.x should allow for an easier transition.
