我正在使用
Spring Hibernate Spring-MVC.
我想定义一个自定义约束,结合其他两个预定义的验证注释：@NotNull @Size,如下所示：
我想定义一个自定义约束,结合其他两个预定义的验证注释：@NotNull @Size,如下所示：
- import javax.validation.constraints.NotNull;
- import javax.validation.constraints.Size;
- @NotNull
- @Size(min=4)
- public @interface JPasswordConstraint {
- } // this is not correct. It's just a suggestion.
我想在我的表单模型中使用此注释.
- public class ChangePasswordForm {
- @NotNull
- private String currentPass;
- @JPasswordConstraint
- private String newPass;
- @JPasswordConstraint
- private String newPassConfirm;
- }
UserController.java
- @RequestMapping(value = "/pass",method = RequestMethod.POST)
- public String pass2(Model model,@Valid @modelattribute("changePasswordForm") ChangePasswordForm form,BindingResult result) {
- model.addAttribute("changePasswordForm",form);
- try {
- userService.changePassword(form);
- } catch (Exception ex) {
- result.rejectValue(null,"error.objec",ex.getMessage());
- System.out.println(result);
- }
- if (!result.hasErrors()) {
- model.addAttribute("successMessage","password changed successfully!");
- }
- return "user/pass";
- }
但它不起作用.它接受少于4个字符的密码.
我怎么解决这个问题？
解决方法
这有点晚了,但结合了验证注释的技术
在撰写本文时,可能没有它,但解决方案正在跟进
- @NotNull
- @Size(min=4)
- @Target({ METHOD,FIELD,ANNOTATION_TYPE })
- @Retention(RUNTIME)
- @Constraint(validatedBy = { })
- @Documented
- public @interface JPasswordConstraint {
- String message() default "Password is invalid";
- Class<?>[] groups() default { };
- Class<? extends Payload>[] payload() default { };
- }
