手动调用Spring注释验证
我正在使用Hibernate和Spring Annotations进行很多验证,如下所示:
public class Account { @NotEmpty(groups = {Step1.class, Step2.class})
private String name;
@NotNull(groups = {Step2.class})
private Long accountNumber;
public interface Step1{}
public interface Step2{}
}
然后在控制器中,在参数中调用它:
public String saveAccount(@ModelAttribute @Validated({Account.Step1.class}) Account account, BindingResult result) { //some more code and stuff here
return "";
}
但是我想根据控制器方法中的某些逻辑来决定使用的组。有没有办法手动调用验证?像result = account.validate(Account.Step1.class)
什么?
我知道要创建自己的Validator类,但这是我要避免的事情,我宁愿只在类变量本身上使用批注。
回答:
比Jaiwo99更进一步:
// org.springframework.validation.SmartValidator - implemented by// LocalValidatorFactoryBean, which is funny as it is not a FactoryBean per se (just saying)
@Autowired
SmartValidator validator;
public String saveAccount(@ModelAttribute Account account, BindingResult result) {
// ... custom logic
validator.validate(account, result, Account.Step1.class);
if (result.hasErrors()) {
// ... on binding or validation errors
} else {
// ... on no errors
}
return "";
}
