JPA 在多個應用程序之間共享的實體（Wildfly - Hibernate - Maven）

Question

有沒有辦法配置各種持久性。xml 包含在所有使用包含所有實體的共享 jar 的不同應用程序（戰爭或耳朵）中？

就像是：

  deployments/
    |-ArchiviBase.war
      |-WEB-INF\classes\META-INF\persistence.xml
      |-WEB-INF\classes\META-INF\TipoAbitazione.hbm.xml
    |-Application2.war
      |-WEB-INF\classes\META-INF\persistence.xml
    |-Application3.war
      |-WEB-INF\classes\META-INF\persistence.xml
  lib/
    |-models.jar
      |- it\test\archiviBase\beans\TipoAbitazione.java

With all files (persistence.xml, hbm.xml and java class) within the war the mapping works correctly, but I need to share java entities with all applications, so I would like to move them to models.jar.

持久性.xml

TipoAbitazione.java

package it.test.archiviBase.beans;

import java.io.Serializable;
 
public class TipoAbitazione implements Serializable {

    private static final long serialVersionUID = 1L;

    private String codice;
    private String descrizione;
    private Boolean attivo;

    public TipoAbitazione() {
    }

    public TipoAbitazione(String codice, String descrizione) {
        this.codice = codice;
        this.descrizione = descrizione;
    }

    public TipoAbitazione(String codice, String descrizione, Boolean attivo) {
        this.codice = codice;
        this.descrizione = descrizione;
        this.attivo = attivo;
    }

    public String getCodice() {
        return this.codice;
    }

    public void setCodice(String codice) {
        this.codice = codice;
    }

    public String getDescrizione() {
        return this.descrizione;
    }

    public void setDescrizione(String descrizione) {
        this.descrizione = descrizione;
    }

    public Boolean getAttivo() {
        return this.attivo;
    }

    public void setAttivo(Boolean attivo) {
        this.attivo = attivo;
    }
}

每個應用程序都應該定義自己的持久性單元，使用自己的 hbm.xml 文件，但 java 實體將全部包含在共享模型中。jar

這是我嘗試部署戰爭時的錯誤：

Answer 1

<!-- Define persistence unit -->
<persistence-unit name="archiviBasePU">
    ...
    <jar-file>models.jar</jar-file>
    ...
</persistence-unit>

Answer 2

如果您不想在每個應用程序的 persistence.xml 中明確列出它們，則必須將persistence.xml與加載的類放在同一個庫中。
