Java 为什么方法级验证在Spring中不起作用？

学生班级：

package com.solvegen.education.student.enrollment.core.model;

import com.sun.istack.internal.NotNull;

import java.util.Date;

public class Student {
    private Long id;

    @NotNull
    private String userName;

    @NotNull
    private String firstName;

    @NotNull
    private String lastName;

    @NotNull
    private String password;

    @NotNull
    private String emailAddress;

    @NotNull
    private Date dateOfBirth;

    public Date getDateOfBirth() {
        return dateOfBirth;
    }

    public String getEmailAddress() {
        return emailAddress;
    }

    public String getFirstName() {
        return firstName;
    }

    public Long getId() {
        return id;
    }

    public String getLastName() {
        return lastName;
    }

    public String getPassword() {
        return password;
    }

    public String getUserName() {
        return userName;
    }

    public void setDateOfBirth(Date dateOfBirth) {
        this.dateOfBirth = dateOfBirth;
    }

    public void setEmailAddress(String emailAddress) {
        this.emailAddress = emailAddress;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

}

spring-config.xml的内容

<bean id="validator"
      class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="providerClass" value="org.hibernate.validator.HibernateValidator"/>
</bean>
<bean id="validatorPostProcessor"
      class="org.springframework.validation.beanvalidation.MethodValidationPostProcessor">
    <property name="validator" ref="validator"/>
</bean>

当我在方法声明中使用

@NotNull

而不是

@Valid

时，所有工作正常（当我传递null而不是Student类实例时，验证框架抛出异常）

我做错了什么？或者字符串中的方法级验证不支持参数的@Valid注释？

问题出在com.sun.istack.internal.NotNull中。我从不正确的包装中进口。必须是javax.validation.constraints.NotNull

我不明白这个问题。你在做什么，你期望会发生什么，会发生什么？对不起，各位。问题出现在com.sun.istack.internal.NotNull中。我从不正确的包装中进口。必须是javax.validation.constraints.NotNull
