Spring自定义验证器-使用参数插入消息

public class CustomValidator implements Validator {

    @Override
    public boolean supports(Class<?> clazz) {
        return YourModelClass.class.equals(clazz);
    }

    @Override
    public void validate(Object target, Errors errors) {
        YourModelClass model = (YourModelClass) target;

        // 执行验证逻辑
        if (model.getName() == null || model.getName().isEmpty()) {
            errors.rejectValue("name", "name.empty", "Name cannot be empty");
        }

        // 添加其他验证规则...

    }
}

@PostMapping("/your-endpoint")
public String yourControllerMethod(@Validated CustomModel model, BindingResult result) {
    if (result.hasErrors()) {
        // 处理验证错误
    }

    // 处理正常逻辑

    return "success";
}
