hibernate验证器的问题 - javax.persistence.RollbackException（spring）

标签： java spring hibernate validation

我试图在我的maven项目中插入验证，但之后我的项目不再工作了。这是我的代码：

我的实体类：

    @Table(name="Kandidati")
public class Candidate {
    @Id
    @Column(nullable=false)
    @Size(min=13, max=13, message="JMBG mora imati 13 karaktera! ")
    private String upn;

    @Size(min=2, message="Ime mora imati najmanje 2 slova! ")
    @Column(nullable=false)
    private String name;

    @Column(nullable=false)
    @Size(min=3, message="Prezime mora imati najmanje 3 slova! ")
    private String surname;

    @NotNull
    @Size(min=4, max=4, message="Godina mora imati 4 broja! ")
    private int year;

    @Email(message="Greska! Email adresa nije validna!")
    @Column(nullable=false)
    private String email;

    @Column(nullable=false)
    @Size(min=8, message="Telefon mora imati najmanje 8 karaktera! ")
    private String telephone;

    @Column(length=255)
    private String comment;

    @Size(min=2, max=2, message="Podatak treba da ima tacno 2 karaktera! ")
    @Column(nullable=false)
    private String hired;

当然，也有吸气剂和制定者，然后在我的.jsp页面中我放

            <form:errors path="name"></form:errors>

对于每个属性，在dispatcher-servlet.xml中我放

    <mvc:annotation-driven/>

在我的CandidateController课程中，我有：

@RequestMapping(value="/kandidati", method=RequestMethod.POST)
    public String doRegister(@Valid @ModelAttribute("candidate") Candidate candidate, BindingResult result) {
        if (result.hasErrors()) {
            return "newCandidate";

        }
        candidateService.save(candidate);
        return "newCandidate";
    }

当我使用Tomcat启动应用程序时，我收到此错误：

谁能告诉我哪里弄错了？

1 个答案:

答案 0 :(得分：1)

  

找不到类型为：java.lang.Integer

的验证程序

我怀疑这是罪魁祸首：

@NotNull
@Size(min=4, max=4, message="Godina mora imati 4 broja! ")
private int year;

According to the docs，@Size只能应用于CharSequence，Collection，Map和arrays。

要解决此问题，请将@Size注释替换为@Digits。 

@Digits(integer=4, message="Godina mora imati 4 broja! ")
private int year;

考虑到int不能为空，您也可以放弃@NotNull检查（或保留它并将int转换为Integer）
