You have a requirement to validate an object graph with nested objects and associations using JSR-303 Bean Validation. How would you achieve this, ensuring that the entire object graph is validated?
- Create a custom validation group and apply it to the top-level object. Then, implement custom validation logic for the entire object graph within this validation group. Manually invoke the validation process on the top-level object, which will validate the entire object graph, including nested objects and associations.
- Implement a custom validation interceptor that intercepts object creation or modification operations. In the interceptor, perform validation on the entire object graph, including nested objects and associations. This ensures that validation is consistently applied to object graphs.
- Use Spring Boot's built-in automatic object graph validation feature by enabling it in the application properties. This feature will automatically validate object graphs, including nested objects and associations, when standard JSR-303 annotations are used. Customize the error messages and response format as needed in the application properties.
- Use cascading validation by annotating the relevant fields or methods with @Valid. Ensure that the target object's associated objects are also annotated with @Valid. When validation is triggered, it will recursively validate the entire object graph, including nested objects and associations.
To validate an object graph with nested objects and associations using JSR-303 Bean Validation, you should use cascading validation by annotating the relevant fields or methods with @Valid. This ensures that the entire object graph is validated, including nested objects and associations. This is a standard and recommended approach in Spring Boot applications.
