How to run Spring 3.0 PetClinic in tomcat with Hibernate backed JPA

提问by Enno Shioji

OK, this probably is supposed to be the easiest thing in the world, but I've been trying for the entire day, and it's still not working.. Any help is highly appreciated!

好的，这可能应该是世界上最简单的事情，但我已经尝试了一整天，但仍然无法正常工作.. 非常感谢任何帮助！

My wrong (since I did not disabled LoadTimeWeaving) procedure is left for reference..:

我的错误（因为我没有禁用 LoadTimeWeaving）程序留作参考..：

What I did:

我做了什么：

1. Downloaded Tomcat 6.0.26 & Spring 3.0.1
2. Downloaded PetClinic from https://src.springframework.org/svn/spring-samples/petclinic
3. Built & deployed petclinic.war. Ran fine with default JDBC persistence.
4. Edited webapps/WEB-INF/spring/applicationContext-jpa.xml and set jpaVendorAdaptorto Hibernate.
5. Edited webapps/WEB-INF/web.xml and changed context-paramfrom applicationContext-jdbc.xml to applicationContext-jpa.xml
6. Copied everything in the Spring 3.0.1 distribution to TOMCAT_HOME/lib.

7. Launched tomcat. Saw

   Caused by: java.lang.IllegalStateException: ClassLoader [org.apache.catalina.loader.WebappClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:spring-agent.jar

8. Uncommented line <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>in webapps/META-INF/context.xml.

9. Same error. Added that line to TOMCAT_HOME/context.xml

10. Deployed without error. However, when I do something it will issue an error saying

    java.lang.NoClassDefFoundError: javax/transaction/SystemException at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:39)

    11.Changed scope of javax.transaction from test to default (just deleted test), as suggested by scaffman.

    12.Runs fine!! Thank you!

1. 下载 Tomcat 6.0.26 & Spring 3.0.1
2. 从https://src.springframework.org/svn/spring-samples/petclinic下载 PetClinic
3. 构建和部署 petclinic.war。使用默认的 JDBC 持久性运行良好。
4. 编辑 webapps/WEB-INF/spring/applicationContext-jpa.xml 并设置jpaVendorAdaptor为 Hibernate。
5. 编辑 webapps/WEB-INF/web.xml 并context-param从 applicationContext-jdbc.xml更改为 applicationContext-jpa.xml
6. 将 Spring 3.0.1 发行版中的所有内容复制到 TOMCAT_HOME/lib。

7. 推出了tomcat。锯

   引起：java.lang.IllegalStateException：ClassLoader [org.apache.catalina.loader.WebappClassLoader] 不提供“addTransformer(ClassFileTransformer)”方法。指定自定义 LoadTimeWeaver 或使用 Spring 的代理启动 Java 虚拟机：-javaagent:spring-agent.jar

8. <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>webapps/META-INF/context.xml 中未注释的行。

9. 同样的错误。将该行添加到 TOMCAT_HOME/context.xml

10. 部署没有错误。但是，当我做某事时它会发出一个错误说

    java.lang.NoClassDefFoundError: javax/transaction/SystemException at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:39)

    11.按照 scaffman 的建议，将 javax.transaction 的范围从测试更改为默认值（只是删除了测试）。

    12.运行正常！！谢谢！

Ok, here is what I did:

好的，这是我所做的：

1. Get Tomcat 6.0.26

2. Checkout the petclinic sample:

   svn co https://src.springframework.org/svn/spring-samples/petclinic/trunk/ petclinic
   

3. cdinto the petclinic directory

4. Modify src/main/webapp/WEB-INF/spring/applicationContext-jpa.xmlto use Hibernate:
   • COMMENT the <context:load-time-weaver>(load-time weaver SHOULD NOTbe used with Hibernate, this is for Toplink)
   • Declare Hibernate as jpaVendorAdapter(comment the Toplink part, uncomment the Hibernate part)
5. Modify the src/main/webapp/WEB-INF/web.xmlto use the applicationContext-jpa.xml

6. Modify the pom.xmlto bundle jta.jarin the war (as pointed out by @skaffman):

   <dependency>
     <groupId>javax.transaction</groupId>
     <artifactId>com.springsource.javax.transaction</artifactId>
     <version>1.1.0</version>
     <!--scope>test</scope-->
   </dependency>
   

7. Build the war

   mvn install
   

8. Deploy it to Tomcat

   cp target/petclinic.war $TOMCAT_HOME/webapps
   

9. Browse

   http://localhost:8080/petclinic
   

1. 获取 Tomcat 6.0.26

2. 查看宠物诊所样本：

   svn co https://src.springframework.org/svn/spring-samples/petclinic/trunk/ petclinic
   

3. cd进入 petclinic 目录

4. 修改src/main/webapp/WEB-INF/spring/applicationContext-jpa.xml为使用Hibernate：
   • 评论<context:load-time-weaver>（加载时编织器不应与 Hibernate 一起使用，这是用于 Toplink）
   • 声明 Hibernate 为jpaVendorAdapter（注释 Toplink 部分，取消注释 Hibernate 部分）
5. 修改src/main/webapp/WEB-INF/web.xml使用applicationContext-jpa.xml

6. 在war中修改pom.xmlto bundle jta.jar（如@skaffman 所指出的）：

   <dependency>
     <groupId>javax.transaction</groupId>
     <artifactId>com.springsource.javax.transaction</artifactId>
     <version>1.1.0</version>
     <!--scope>test</scope-->
   </dependency>
   

7. 建立War

   mvn install
   

8. 部署到Tomcat

   cp target/petclinic.war $TOMCAT_HOME/webapps
   

9. 浏览

   http://localhost:8080/petclinic

Looks like a problem with PetClinic packaging:

看起来像 PetClinic 包装的问题：
