在看spring in actin第四版, 第五章5.4.2校驗(yàn)數(shù)據(jù)這節(jié), 使用JSR303進(jìn)行數(shù)據(jù)校驗(yàn), 但是沒(méi)有生效, 也沒(méi)有報(bào)錯(cuò)

使用的是hibernate-validator的實(shí)現(xiàn), gradle依賴:

compile group: 'org.hibernate', name: 'hibernate-validator', version: '6.0.9.Final'

javabean代碼:

public class Spitter {

    private Long id;

    @NotNull
    @Size(min = 5, max = 16)
    private String username;

    @NotNull
    @Size(min = 5, max = 25)
    private String password;

    @NotNull
    @Size(min = 2, max = 30)
    private String firstName;

    @NotNull
    @Size(min = 2, max = 30)
    private String lastName;

    @NotNull
    @Email
    private String email;
        
   // getter and setter
}

controller相關(guān)代碼塊:

 @RequestMapping(value = "/register", method = RequestMethod.POST)
    public String processRegistration(@Valid Spitter spitter, Errors errors) {
        System.out.println(spitter);
        if (errors.hasErrors()) {
            errors.getAllErrors().forEach(System.out::println);
            return "registerForm";
        }

        spitterRepository.save(spitter);

        return "redirect:/spitter/" + spitter.getUsername();
    }
