Spring

spring AnnotationSessionFactoryBean packagesToScan mapping hibernate

今天在给公司新来的同事讲解项目架构的时候,项目中用到了JPA 正向生成数据库的技术,每新建一个pojo @entity,都需要在 hibernate.cfg.xml 增加一个 mapping

有位同事就问,可不可以使用通配符,不用每次配一个,而且以前负责过Nike 商城的发布,经常发现开发工程师没有在项目发布模版文档里面,把新增的 mapping 写上,导致项目发布出现exception

要是真能做到,新增一个entity,删除一个entity,不用修改 hibernate.cfg.xml 就好了 ,

下面附上我实践的全过程,(要是不想看我废话的,直接拉到最后看我的配置)

晚上实践了下 ,

      <mapping class="com.jumbo.model.*" />

走,启动

   ... 30 more
Caused by: org.hibernate.MappingException: Unable to load class declared as <mapping class="com.jumbo.model.*"/> in the configuration:
   at org.hibernate.cfg.AnnotationConfiguration.parseMappingElement(AnnotationConfiguration.java:740)
   at org.hibernate.cfg.Configuration.parseSessionFactory(Configuration.java:1647)
   at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1626)
   at org.hibernate.cfg.AnnotationConfiguration.doConfigure(AnnotationConfiguration.java:1224)

报错了,

网上搜搜,是不是我通配符配置错了,再来

<mapping class="com.jumbo.model.**.*" />

at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1417)

   ... 76 more
Caused by: java.lang.ClassNotFoundException: com.jumbo.model.**.*
   at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1516)
   at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1361)
   at java.lang.Class.forName0(Native Method)
   at java.lang.Class.forName(Class.java:169)

哥杯具了

看了下dtd,貌似 mapping还有其他属性(package),试试

      <mapping package="com.jumbo.model" />

走,启动,日志里面只有这么一句

19:46:24,177 INFO  [Configuration] configuring from url: file:/E:/Workspaces/baozun/usercenter/usercenter-frontend/src/main/webapp/WEB-INF/classes/hibernate.cfg.xml
19:46:24,364 INFO  [AnnotationConfiguration] Mapping package com.jumbo.model
19:46:24,599 INFO  [Configuration] Configured SessionFactory: null

但是没有以前见到的表和 entity 一一对应的效果,貌似没有成功,表(member)里面增加个字段(test)试试

/*************************************************************************************/
   private String           test;
 
   /** PK */
   private Long          id;

setter,getter 方法

启动,去数据库看看,表没有新增我刚加的test 字段,看来是配置不成功,

去看看 package到底是做什么的,以前没有接触过,接触过最多的就是反向工程的 resource(xml 配置),以及正向工程的 class(annotition配置),

网上还找不到具体的介绍,都说这个package 没用

哥心说,”没用的话,hibernate 设置这个值干嘛吃的?” 继续找,终于在 http://www.jetbrains.net/jira/browse/HBR-4 文档里面 ,发现有牛人回复了

写道

Tag <mapping package="somePackage"/> of hibernate.cfg.xml applies to package-level annotations (i.e., annotations specified for a package, e.g. @javax.persistence.NamedQuery) and a package-info.java file must exists with the annotations.
This is not a problem or shortcoming of Hibero.
To specify mapping entities using annotations use the tag <mapping class="fqclassname"/>.

啊,原来 package 用在 package 注释级别的

看来我的用法是错的,但是我的entity 总不能去改吧,(再说这个package 到底怎么用,还不清楚撒)想想有没有其他的办法,

活人怎么能给尿憋死, 国内国外像我这么懒的人肯定有(不想手写那么多的mapping啊 ),

找找资料 ,果然有”前辈”, http://stackoverflow.com/questions/1413190/hibernate-mapping-package

娃哈哈,spring 的AnnotationSessionFactoryBean 有自动扫描(packagesToScan)的功能 ,尝试着用用看

不过我们的sessionFactory bean 被我们的架构师封装在 loxia jar 里面

那么我就重写一个

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="configLocation">
        <value>classpath:hibernate.cfg.xml</value>
      </property>
       <property name="packagesToScan" value="com.jumbo.model" />
       </bean>

启动的时候会自动replace

看日志

18:20:16,095 INFO  [DefaultListableBeanFactory] 
Overriding bean definition for bean 'sessionFactory': replacing [Generic bean: class [org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null;

defined in URL [jar:file:/E:/Workspaces/baozun/usercenter/usercenter-frontend/src/main/webapp/WEB-INF/lib/loxia2-core-2.5.jar!/loxia-hibernate-context.xml]]

我的 hibernate配置文件里面 , 还有named query

      <mapping resource="META-INF/orm-master.xml" />
      <mapping resource="META-INF/orm-member.xml" />
      <mapping resource="META-INF/orm-sales.xml" />
      <mapping resource="META-INF/orm-system.xml" />

研究加实验下 ,发现了 mappingDirectoryLocations,心想要是只配个 文件夹 META-INF,自动扫描出下面的orm-*.xml 世界都美妙阿

go,尝试下

   <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="configLocation" value="classpath:hibernate.cfg.xml" />
      <property name="packagesToScan">
        <list>
           <value>com.jumbo.model</value>
        </list>
      </property>
      <property name="mappingDirectoryLocations">
        <list>
           <value>/META-INF</value>
        </list>
      </property>
   </bean>

发现没有起作用, 敏思苦想,文件夹式配置都不成功

只有去看看源码,一路debug,发现了 hiberntae 这么个method

 public Configuration addDirectory(File dir) throws MappingException {
      File[] files = dir.listFiles();
      for ( int i = 0; i < files.length ; i++ ) {
        if ( files[i].isDirectory() ) {
           addDirectory( files[i] );
        }
        else if ( files[i].getName().endsWith( ".hbm.xml" ) ) {
           addFile( files[i] );
        }
      }
      return this;
   }

噢,原来文件名必须.hbm.xml 结尾才加如到 Configuration, .hbm.xml一般都是配置映射关系的,我的只是namedquery 文件 ,那么 mappingDirectoryLocations这东东我们就用不了,再看看 有没有其他的配置方式

   <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="configLocation" value="classpath:hibernate.cfg.xml" />
      <property name="packagesToScan">
        <list>
           <value>com.jumbo.model</value>
        </list>
      </property>
      <property name="mappingLocations">
        <list>
           <value>/META-INF/orm-*.xml</value>
        </list>
      </property>
   </bean>

这个可以读取到配置的namedquery了 ,查看源码

@Override
   public void add(org.dom4j.Document doc) throws MappingException {
      boolean ejb3Xml = "entity-mappings".equals( doc.getRootElement().getName() );
      if ( inSecondPass ) {
        //if in second pass bypass the queueing, getExtendedQueue reuse this method
        if ( !ejb3Xml ) {
           super.add( doc );
        }
      }
      else {
        if ( !ejb3Xml ) {
           final Element hmNode = doc.getRootElement();
           Attribute packNode = hmNode.attribute( "package" );
           String defaultPackage = packNode != null
                 ? packNode.getValue()
                 : "";
           Set<String> entityNames = new HashSet<String>();
           findClassNames( defaultPackage, hmNode, entityNames );
           for ( String entity : entityNames ) {
              hbmEntities.put( entity, doc );
           }
           hbmDocuments.add( doc );
        }
        else {
           final MetadataProvider metadataProvider = ( ( MetadataProviderInjector ) reflectionManager ).getMetadataProvider();
           JPAMetadataProvider jpaMetadataProvider = ( JPAMetadataProvider ) metadataProvider;
           List<String> classnames = jpaMetadataProvider.getXMLContext().addDocument( doc );
           for ( String classname : classnames ) {
              try {
                 annotatedClasses.add( reflectionManager.classForName( classname, this.getClass() ) );
              }
              catch ( ClassNotFoundException e ) {
                 throw new AnnotationException( "Unable to load class defined in XML: " + classname, e );
              }
           }
        }
      }
   }

恩,是以InputStream 的形式,xml root element 是 entity-mappings文件 ,yes 是我要的东东 ,

这么配置,我们看看log,是不是和以前差不多

yes,没错

好了, hibernate.cfg.xml里面就留下自己的参数配置

<session-factory>

      <property name="show_sql">false</property>
      <property name="format_sql">false</property>
      <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
      <property name="hibernate.query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
 
 
      <property name="hibernate.jdbc.batch_size">100</property>
   </session-factory>
</hibernate-configuration>

spring.xml 里面配置

<!--over write sessionFactory in loxia-hibernate-context.xml-->
   <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      <property name="dataSource" ref="dataSource" />
      <property name="configLocation" value="classpath:hibernate.cfg.xml" />
      <property name="packagesToScan">
        <list>
           <value>com.jumbo.model</value>
        </list>
      </property>
      <property name="mappingLocations">
        <list>
           <value>/META-INF/orm-*.xml</value>
        </list>
      </property>
   </bean>

就可以把所有原来写在 hibernate.cfg.xml 里面的 mapping 给干掉了 ,以后没新增或者删除一个@entity,不用去动hibernate.cfg.xml

附加一句 , hibernate.cfg.xml 关于hibernate的参数也可以在 spring 里面配置,但是个人认为这部分的参数,仍然在hibernate 里面配置比较好,反正在spring 里面配置这些参数也得写这么多代码
