java如何将SpringMVC、hibernate、hibernate验证器结合使用？

Question

我想在我的项目中使用spring mvc hibernate hibernate validator。但在我所应用的类中，验证和mysql验证是重叠的。通常情况下使用这两种方法。还是用另一种方式

@Id
@Column(name="id")
@GeneratedValue(strategy=GenerationType.IDENTITY)
Integer id;

@Column(name="firstname")
@NotBlank(message="Name mustn't be empty.")
@Size(max=20,min=2,message="Your name must be between 2-20.")
@Pattern(regexp ="([a-zA-Z]+)",message="You can't enter number or symols or Turkish caracter.")
String firstname;

@Column(name="lastname")
@NotBlank(message="Last name mustn't be empty.")
@Size(max=20,min=2,message="Your lastname must be between 2-20.")
@Pattern(regexp ="([a-zA-Z]+)",message="You can't enter number or symols or Turkish caracter.")
String lastname;

@Column(name="date")
@NotBlank
@DateTimeFormat(pattern="yyyy-mm-dd")
@DateValid
String date;

您可以同时使用spring mvc、hibernate、hibernate validator，并且没有冲突。有一个名为JHipster的好项目，你可以看到如何使用这些技术来获得它

Wouldn't we have created code confusion using so many anotations?

这是jhipster用户类：

@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
@SequenceGenerator(name = "sequenceGenerator")
private Long id;

@NotNull
@Pattern(regexp = Constants.LOGIN_REGEX)
@Size(min = 1, max = 50)
@Column(length = 50, unique = true, nullable = false)
private String login;

@JsonIgnore
@NotNull
@Size(min = 60, max = 60)
@Column(name = "password_hash", length = 60, nullable = false)
private String password;

@Size(max = 50)
@Column(name = "first_name", length = 50)
private String firstName;

@Size(max = 50)
@Column(name = "last_name", length = 50)
private String lastName;

@Email
@Size(min = 5, max = 254)
@Column(length = 254, unique = true)
private String email;

@NotNull
@Column(nullable = false)
private boolean activated = false;

java中通常有两种类型的配置

• 注释
• XML配置
