如何在CamelBlueprintTestSupport中加载spring上下文xml文件以及如何在spring上下文xml中获取数据源对象

如何在CamelBlueprintTestSupport中加载spring上下文xml文件，以及如何在spring上下文xml中获取数据源对象，问题是我在com.hotel.common.persistence.dao.DAOFactory.getDAO（DAOFactory.java:27）上遇到了类似java.lang.NullPointerException的异常我的假设是DAOFactory类没有得到映射器类。对吗

我已经和你分享了我的示例代码

这是我的测试课

公共类ContextRouteGetAvailabilityXmlTest扩展了CamelBlueprintTest支持{

@Override
protected String getBlueprintDescriptor() {
    return "OSGI-INF/blueprint/context-beans.xml,OSGI-INF/blueprint/context-config.xml,OSGI-INF/blueprint/context-route-getAvailability.xml";
}


@Override
protected void addServicesOnStartup(Map<String, KeyValueHolder<Object, Dictionary>> services){
    BasicDataSource datasource = new BasicDataSource();

    datasource.setDriverClassName("com.mysql.jdbc.Driver");
    datasource.setUrl("jdbc:mysql://my ip:3306/test");
    datasource.setUsername("test");
    datasource.setPassword("test1");
    datasource.setConnectionProperties("useUnicode=yes;characterEncoding=utf8;");

    services.put("dataSourceMySQL", asService(datasource, null));
}

@覆盖
受保护的字符串getBlueprintDescriptor（）{
返回“OSGI-INF/blueprint/context bean.xml，OSGI-INF/blueprint/context config.xml，OSGI-INF/blueprint/context route getAvailability.xml”；
}
@凌驾
受保护的void addServicesOnStartup（映射服务）{
BasicDataSource数据源=新的BasicDataSource（）；
setDriverClassName（“com.mysql.jdbc.Driver”）；
setUrl（“jdbc:mysql://my ip:3306/测试）；
datasource.setUsername（“测试”）；
setPassword（“test1”）；
setConnectionProperties（“useUnicode=yes；characterEncoding=utf8；”；
put（“dataSourceMySQL”，asService（datasource，null））；
}

}

这是我的spring context.xml文件

<osgi:reference id="dataSourceMySQL" interface="javax.sql.DataSource"/>

<bean id="mybatisConfig" class="org.springframework.core.io.ClassPathResource">
    <constructor-arg value="/META-INF/config/mybatis-config.xml" />
</bean>

<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSourceMySQL" />
    <property name="configLocation" ref="mybatisConfig" />
</bean>

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg index="0" ref="sqlSessionFactoryBean" />
</bean>

<!-- scan for mappers and let them be autowired -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.sia.csl.hotel.common.persistence.mapper" />
    <property name="sqlSessionTemplateBeanName" value="sqlSession" />
</bean>

<bean id="daoFactory"
    class="com.common.persistence.dao.DAOFactory" />

OSGi Blueprint不支持Spring XML文件，只支持Blueprint XML文件。因此，您无法使用

CamelBlueprintTestSupport

加载SpringXML文件。相反，您可以通过驼峰测试弹簧模块使用常规弹簧

---

如果您在OSGi上运行，那么SpringXML文件（SpringDM）将被弃用和EOL，并且不应使用。相反，您应该将Spring XML文件迁移到OSGI Blueprint文件。

通过这种方式，我尝试加载db，并与您共享了我的DAOFactory.java文件

<osgi:reference id="dataSourceMySQL" interface="javax.sql.DataSource"/>

<bean id="mybatisConfig" class="org.springframework.core.io.ClassPathResource">
    <constructor-arg value="/META-INF/config/mybatis-config.xml" />
</bean>

<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSourceMySQL" />
    <property name="configLocation" ref="mybatisConfig" />
</bean>

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg index="0" ref="sqlSessionFactoryBean" />
</bean>

<!-- scan for mappers and let them be autowired -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.sia.csl.hotel.common.persistence.mapper" />
    <property name="sqlSessionTemplateBeanName" value="sqlSession" />
</bean>

<bean id="daoFactory"
    class="com.common.persistence.dao.DAOFactory" />

    logger.debug("getDAO sqlSessionTemplate: "+sqlSessionTemplate);
    if(sqlSessionTemplate == null ) {
        setBundleContext(FrameworkUtil.getBundle(DAOFactory.class).getBundleContext());
        sqlSessionTemplate = getSqlSession() ;
        logger.debug("Received sqlSessionTemplate: "+sqlSessionTemplate);
    }
    return sqlSessionTemplate.getMapper(DaoClassName);

        final ServiceReference[] applicationContextRefs = bundleContext.getServiceReferences(ApplicationContext.class.getName(), filter);
        @SuppressWarnings("unchecked")
        final ApplicationContext applicationContext = (ApplicationContext) bundleContext.getService(applicationContextRefs[0]);

        return applicationContext;
