在多个应用程序之间共享的 JPA 实体(Wildfly - Hibernate - Maven) - JPA Entities shared between several applications (Wildfly - Hibernate

有没有办法配置各种持久性.xml包含在不同的应用程序(战争或耳朵)中，这些应用程序都使用包含所有实体的共享 jar？

像这样：

deployments/
|-ArchiviBase.war
|-WEB-INFclassesMETA-INFpersistence.xml
|-WEB-INFclassesMETA-INFTipoAbitazione.hbm.xml
|-Application2.war
|-WEB-INFclassesMETA-INFpersistence.xml
|-Application3.war
|-WEB-INFclassesMETA-INFpersistence.xml
lib/
|-models.jar
|- ittestarchiviBasebeansTipoAbitazione.java

对于战争中的所有文件(持久性.xml，hbm.xml和java类)，映射可以正常工作，但是我需要与所有应用程序共享java实体，因此我想将它们移动到模型.jar。

坚持不懈.xml

<?xml version="1.0" encoding="UTF-8"?>

</persistence>

TipoAbitazione.hbm.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;
}
}

每个应用程序都应该使用自己的 hbm.xml 文件定义自己的持久性单元，但 java 实体将全部包含在共享模型.jar文件中

这是我尝试部署战争时的错误：

如果您不想在每个应用程序的持久性.xml中显式列出persistence.xml，则必须将它们与加载的类放在同一个库中。
