springboot中validator数据校验功能的实现

user.id.notnull = id 不能为空
user.username.size = username 长度为5-10
user.age.min = age 年龄最小为1
user.age.max = age 年龄最大为100
user.email.pattern= email 格式不正确

public class User {
    @NotNull(message = "{user.id.notnull}")
    private Integer id;
    @Size(min = 5,max = 10,message = "{user.username.size}")  // @Size  字符串长度
    private String username;
    @DecimalMin(value = "1",message = "{user.age.min}") // @DecimalMin 数值最小
    @DecimalMax(value = "100",message = "{user.age.max}")
    private Integer age;
    @Email(message = "{user.email.pattern}")
    private String  email;
}

public class User {
    @NotNull(message = "{user.id.notnull}",groups = {ValidationGroup01.class,ValidationGroup02.class})
    private Integer id;
    @Size(min = 5,max = 10,message = "{user.username.size}",groups = {ValidationGroup01.class})  // @Size  字符串长度
    private String username;
    @DecimalMin(value = "1",message = "{user.age.min}") // @DecimalMin 数值最小
    @DecimalMax(value = "100",message = "{user.age.max}")
    private Integer age;
    @Email(message = "{user.email.pattern}",groups = {ValidationGroup01.class})
    private String  email;
}

    public void addUser(@Validated(value = ValidationGroup01.class) User user, BindingResult result){
     		...
    }
