获取spring的applicationContext.xml内的Bean实体

时间：2010-08-02 来源：fucuihong

一般情况下，我们都是使用webProject开发网站之类的web项目，一般在applicationContext.xml文件中配置的bean实体都由spring负责注入，我们只需在web.xml中加载applicatinContext.xml文件并在需要使用的地方写个此bean的getter/setter方法即可。例如： web.xml文件中加载application.xml: <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
   /WEB-INF/classes/applicationContext.xml,
   /WEB-INF/classes/applicationContext-alarm.xml,
   /WEB-INF/classes/applicationContext-demo.xml
  </param-value>
</context-param> applicationContext.xml中注入了： <bean id="CompareChartDao"
  class="pas.dao.comparechart.CompareChartDaoImpl">
  <property name="hibernateTemplate" ref="hibernateTemplate"></property>
</bean> <bean id="LayoutDao" class="pas.dao.layout.LayoutDaoImpl">
  <property name="hibernateTemplate" ref="hibernateTemplate"></property>
</bean> ... ... 那么在需要使用以上两个bean的类中，则需要： private CompareChartDao compareChartdao;
private LayoutDao layoutDao; public CompareChartDao getCompareChartdao() {
  return compareChartdao;
} public void setCompareChartdao(CompareChartDao compareChartdao) {
  this.compareChartdao = compareChartdao;
} public LayoutDao getLayoutDao() {
  return layoutDao;
} public void setLayoutDao(LayoutDao layoutDao) {
  this.layoutDao = layoutDao;
} public useTwoBean() { //直接使用compareChartdao和layoutDao变量即可。 String configurationId=21; String widgetId=32; compareChartdao.deleteCompareChart(configurationId); Widget widget = layoutDao.getWidget(widgetId); } 以上是开发webProject项目时获取spring的applicationContext.xml内的Bean实体的方法；由于公司最近要开发一个非web项目，非web项目没有web.xml启动时加载applicationContext.xml，那么怎么样来获取applicationContext.xml中注册的实体呢？例如我的applicationContext.xml内容如下： 
<bean id="pasThresholdMgtSessionFactory"
  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
  scope="singleton">   <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">
     org.hibernate.dialect.Oracle10gDialect
    </prop>
    <prop key="hibernate.show_sql">false</prop>
    <prop key="hibernate.proxool.xml">proxool.xml</prop>
    <prop key="hibernate.proxool.pool_alias">demo</prop>
    <prop key="hibernate.connection.provider_class">
     org.hibernate.connection.ProxoolConnectionProvider
    </prop>
    <prop key="hibernate.jdbc.fetch_size">20</prop>
    <prop key="hibernate.default_batch_fetch_size">8</prop>
    <prop key="hibernate.jdbc.batch_size">20</prop>     <prop key="hibernate.hbm2ddl.auto">update</prop>     <prop key="hibernate.cache.use_query_cache">true</prop>     <prop key="hibernate.cache.use_structured_entries">
     true
    </prop>
    <prop key="hibernate.cache.provider_class">
     org.hibernate.cache.EhCacheProvider
    </prop>
    <prop key="hibernate.connection.autocommit">true</prop>    </props>
   
  </property>
  <property name="mappingLocations">
   <list>
    <value>src/hbm/*.hbm.xml</value>
   </list>
  </property>
</bean> <bean id="transactionManager"
  class="org.springframework.orm.hibernate3.HibernateTransactionManager"
  scope="singleton">
  <property name="sessionFactory" ref="pasThresholdMgtSessionFactory" />
</bean> <bean id="hibernateTemplate"
  class="org.springframework.orm.hibernate3.HibernateTemplate"
  abstract="false" lazy-init="default" autowire="default"
  dependency-check="default">
  <constructor-arg ref="pasThresholdMgtSessionFactory" />
</bean> 我本人采取的方式为： ApplicationContext act =   new   FileSystemXmlApplicationContext("src\\applicationContext.xml");//加载applicationContext内容 //获取并使用applicationContext.xml中的实体bean HibernateTemplate htemplate=(HibernateTemplate)act.getBean("hibernateTemplate");
  Rule rule=(Rule)htemplate.get(Rule.class, "1");
  System.out.println("id: "+rule.getID()); 以上仅为本人自己的一点研究，如有不对请大家纠正，特写在此，以备后用。
