In Spring Boot, the @Validated annotation is used in the Controller layer to validate request parameters. Similar to the @Valid annotation, it is used to mark parameters that need validation, but the @Validated annotation has some additional functionalities.<\/p>\n
The @Validated annotation can be used for validation at both the method and parameter levels. By using the @Validated annotation at the method level, validation can be applied to all parameters of the method; whereas at the parameter level, it can be used to validate individual parameters.<\/p>\n
The @Validated annotation also supports group validation, allowing different validation rules to be controlled by specifying different groups for different scenarios. For example, one group can be defined for validation during the creation operation, while another group can be used for validation during the update operation.<\/p>\n
The @Validated annotation also supports controlling the validation sequence. You can define the order of validation by specifying the value of the groups attribute on the validation annotation.<\/p>\n
In general, the purpose of the @Validated annotation is to provide a more flexible and fine-grained request parameter validation functionality, which can better meet various validation requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"
