Question

我正在使用遗留数据库和相应的Java Domain Classes。我正在尝试将Spring Security添加到应用程序中，我也想使用Java Domain Classes，只是为了保持一致并将所有内容保持在一起。使用POGO和POJO时，Grails没有问题，顺便说一句。

因此，从一个新的空数据库和一个新的空grails应用程序开始，我添加了Spring Security Plugin（acegi 0.5.1）。然后我做了：

grails create-auth-domains org.maflt.ibidem.pojo.Person org.maflt.ibidem.pojo.Authority org.maflt.ibidem.pojo.Requestmap

完美无缺。我创建的表格等等。然后我创建了POJO域类并删除了POGO课程。然后一切编译得很好，但是当应用程序启动时我得到了这个错误：

更新

看起来这个问题与AuthorityPeople有关。我添加了一个segregatey id键，使其成为主键并将对象更改为：

package org.maflt.ibidem.pojo;

import java.io.Serializable;
import java.sql.Timestamp;

import javax.persistence.Column;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.JoinColumns;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Transient;
import javax.persistence.Embeddable;

 */
@Entity
@Table(name = "authority_people", catalog = "test")
@SuppressWarnings("serial")
public class AuthorityPeople implements Serializable {

    /**
     * Attribute authority
     */
     private Authority authority;   

    /**
     * Attribute person
     */
     private Person person; 

    /**
     * Attribute id.
     */
    private Long id;


    /**
     * get authority
     */
    @ManyToOne
    @JoinColumn(name = "authority_id")
    public Authority getAuthority() {
        return this.authority;
    }

    /**
     * set authority
     */
    public void setAuthority(Authority authority) {
        this.authority = authority;
    }

    /**
     * get person
     */
    @ManyToOne
    @JoinColumn(name = "person_id")
    public Person getPerson() {
        return this.person;
    }

    /**
     * set person
     */
    public void setPerson(Person person) {
        this.person = person;
    }

    /**
     * <p> 
     * </p>
     * @return id
     */
    @Basic
    @Id
    @Column(name = "id")
        public Long getId() {
        return id;
    }

    /**
     * @param id new value for id 
     */
    public void setId(Long id) {
        this.id = id;
    }



}

现在我收到了这个错误：

Answer 1

Caused by: org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: org.maflt.ibidem.pojo.AuthorityPeople.person in org.maflt.ibidem.pojo.Person.authorityPeoples

听起来像是一个Hibernate问题，而不是Spring Security或者你的POJO或grails。你在Person类中的这个：

@OneToMany(mappedBy="person")
public List<AuthorityPeople> getAuthorityPeoples() {
   return this.authorityPeoples;
}

您的注释是否指的是不正确的内容？

Answer 2

我没有得到这个工作，直到现在，还没有看到任何其他人的证据。所以我采取了移动到grails对象。但我刚发现this solution。我还没有尝试过。我会在发布后发布结果。

顺便说一下 - 如果有人想再看看它，我仍然会对上面的实现提供帮助。

使用带有Spring Security插件的Java域对象
