YotsubaMomo: OSGI : Eclipse Virgo + JPA with EclipseLink(JPA2.0) or Hibernate(JPA 1.0)

本篇主要是針對Eclipse Virgo 3.0.0-RC1 版本上使用JPA 做設定, Virgo 3.0.0 RC1 預設jar 檔是只支援JPA 1.0 ,而Hibernate 官網的jar 檔是不包含OSGI 版本的,所以在這邊針對Hibernate 只有使用在SpringSource EBR 上找到的osgi bundle版本,JPA 2.0是使用EclipseLink 2.3。

JPA 1.0 + Hibernate
首先在SpringSource EBR上可以找到以下的jar 檔,

org.hibernate.ejb-library-3.3.1.ga.libd
com.springsource.org.hibernate.annotations-3.4.0.GA-A.jar
com.springsource.org.hibernate.annotations.common-3.3.0.ga.jar
com.springsource.org.hibernate.ejb-3.4.0.GA-A.jar
com.springsource.org.hibernate-3.3.2.GA.jar

這邊要注意版本的問題,org.hibernate.ejb-library-3.3.1.ga.libd裡面import的 bundle version可能跟下載的版本有些差異,如果碰到exception 可能要手動修改bundle裡面 Import-Package,Require-bundle 的版本資訊,這邊我有手動修改。然後下面的是上面所需要的其他bundle

com.springsource.antlr-2.7.7.jar
com.springsource.org.apache.commons.collections-3.2.0.jarz
com.springsource.org.apache.commons.logging-1.1.1.jar
com.springsource.org.dom4j-1.6.1.jar
com.springsource.org.jgroups-2.5.1.jar
com.springsource.javassist-3.9.0.GA.jar
com.springsource.org.objectweb.asm-1.5.3.jar
com.springsource.net.sf.ehcache-1.5.0.jar
com.springsource.net.sf.jsr107cache-1.0.0.jar

然後將這些放到$EclipseVirgoHome/repository/usr 下,再來就能直接編寫測試用的bundle

先看看project結構

com.gfactor.service.iface 定義了service 的interface ,
com.gfactor.service.internal.dao 定義了dao interface & implements
com.gfactor.service.jpa 定義jpa 的pojo object
下面列出來的的檔案相同也用在JPA 2.0 + EclipseLink 的例子上,

Bndpageinfo entity

package com.gfactor.service.jpa;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="bndpageinfo")
public class Bndpageinfo implements Serializable{
	@Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
	private long id;
	
	@Column(name="bundle_name")
	private String bundle_name;
	
	@Column(name="bundle_version")
	private String bundle_version;
	
	@Column(name="entry_point")
	private String entry_point;
	
	@Column(name="class_name")
	private String class_name;

	public long getId() {
		return id;
	}

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

	



	public String getBundle_name() {
		return bundle_name;
	}

	public void setBundle_name(String bundle_name) {
		this.bundle_name = bundle_name;
	}

	public String getBundle_version() {
		return bundle_version;
	}

	public void setBundle_version(String bundle_version) {
		this.bundle_version = bundle_version;
	}

	public String getEntry_point() {
		return entry_point;
	}

	public void setEntry_point(String entry_point) {
		this.entry_point = entry_point;
	}

	public String getClass_name() {
		return class_name;
	}

	public void setClass_name(String class_name) {
		this.class_name = class_name;
	}
	
	
	@Override
	public String toString() {
		StringBuffer sb = new StringBuffer();
		sb.append("print Bndpageinfo object : \n");
		sb.append("id               : "  id   "\n");
		sb.append("bnudle_name      : "  bundle_name   "\n");
		sb.append("bundle_version   : "  bundle_version   "\n");
		sb.append("entry_point      : "  entry_point   "\n");
		sb.append("class_name       : "  class_name   "\n");
		return sb.toString();
	}
}

再來是Spring的設定, 因為這邊是deploy在osgi container上, 所以datasource 來源也是osgi service , 下面是bundle-context-osgi.xml & bundle-context.xml的設定

bundle-context-osgi.xml

MANIFEST.mf檔透過spring bundlor plugin可以生成,缺少的class 再手動補上就行,如果這邊想要JPA 2.0 + Hibernate 3.5↑的話就比較麻煩了一點,因為hibernate 給的jar檔是不支援osgi的,所以必須自己build一版出來,有需要的話可以參考下面的連結,
Creating custom Hibernate OSGi bundles for JPA 2.0

再來就要設定最麻煩的JPA 2.0 + EclipseLink 2.3, 下面的設定是目前的版本, 除了spring的設定跟persistence.xml 的不同外,就是manifest.mf檔的improt-package要很完整,不然會跳一堆奇奇怪怪的exception出來....

JPA 2.0 + EclipseLink 2.3 Setting

先到EclipseLink 官網下載檔案,要選擇OSGI Bundle 版本的, Latest Release Downloads
下面的檔案放到$EclipseVirgoHome/repository/usr 下面

這邊最主要的問題是context:load-time-weaver, tx:annotation-driven的設定,如果import-package有缺少的話並不一定會有exception,但是transaction可能因此失效,

然後在BndActivator.java裡面做測試,在bundle start,如下

package com.gfactor.service;

import org.springframework.beans.factory.annotation.Autowired;

import com.gfactor.service.iface.IRegisterWicketPageBndIdentify;
import com.gfactor.service.jpa.Bndpageinfo;

public class BndActivator {
	
	@Autowired
	private IRegisterWicketPageBndIdentify registerWicketPageBndIdentify;
	
	public void start(){
		System.out.println("to get registerWicketPageBndIdentify = "  registerWicketPageBndIdentify);
		Bndpageinfo bndobj = new Bndpageinfo();
//		bndobj.setId(10);
		bndobj.setBundle_name("test");
		bndobj.setBundle_version("1.0.0");
		bndobj.setClass_name("testPage");
		bndobj.setEntry_point("test-main");
//		registerWicketPageBndIdentify.registerPageInfo(bndobj);
		registerWicketPageBndIdentify.unregisterPageInfo(bndobj);
//		regWicketPageBndDao.update(bndobj);
		
//		List&lt;Bndpageinfo&gt; getobj =  regWicketPageBndDao.findUser("test2", "1.0.1", "mains") ;
//		System.out.println("getobj = "  getobj);
	}
	
	public void stop(){
		
	}

}

沒問題的話可以在log看到transaction相關的log information,

issue resolve :

整合中碰到的一個exception,
org.aspectj.weaver.tools.jdk14trace error : cannot register non aspect...,然後指向一個class , annotationasyncexecutionaspect,後來找到的問題出在Manifest.mf檔的package,從 Spring transactions with aspectj on Virgo這邊看到相關的問題,這種狀況在Transaction 為jdk proxy 時不會出問題,換成aspectj 後就會找不到transaction,當然最常出現的都是dependency 的問題：xD
