Introducing additional configuration files in spring

I. Introduction of other module XML

In the spring configuration file, sometimes it is necessary to make the configuration of the related entity class more clear for the sub-module.

For example, there is now a job-timer.xml configuration

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd ">    <!--the task class to perform the task.  -    <BeanID= "Testquartz"class= "Com.mc.bsframe.job.TestJob"></Bean>    <!--inject the scheduled tasks that need to be performed into the job.  -    <BeanID= "Testjob"class= "Org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">        < Propertyname= "TargetObject"ref= "Testquartz"></ Property>        <!--methods to be executed in the task class -        < Propertyname= "Targetmethod"value= "DoSomething"></ Property>        <!--The last time the completion is not performed, wait for it to be executed again.  -        < Propertyname= "Concurrent"value= "false"></ Property>    </Bean>    <!--The basic timer will bind to the specific task.  -    <BeanID= "Testtrigger"class= "Org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">        < Propertyname= "Jobdetail"ref= "Testjob"></ Property>        < Propertyname= "Startdelay"value= " the"></ Property>        < Propertyname= "Repeatinterval"value= "200000"></ Property>    </Bean>    <BeanID= "Scheduler"class= "Org.springframework.scheduling.quartz.SchedulerFactoryBean">        < Propertyname= "Triggers">            <List>                <refBean= "Testtrigger"></ref>            </List>        </ Property>    </Bean></Beans>

Use <import resource= "Classpath*:/spring/job-timer.xml"/> introduced in the overall configuration file for spring.

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"Xmlns:scpan= "Http://www.springframework.org/schema/context"xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd Http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd " >    <!--All packages under Com.mc.bsframe are automatically scanned, including the classes under the sub-package except @controller.  -    <Scpan:component-scanBase-package= "Com.mc.bsframe">        <Scpan:exclude-filtertype= "Annotation"expression= "Org.springframework.stereotype.Controller" />        <Scpan:exclude-filtertype= "Annotation"expression= "Org.springframework.web.bind.annotation.ControllerAdvice" />    </Scpan:component-scan>    <!--introducing additional configuration files in spring -    <ImportResource= "Classpath*:/spring/job-timer.xml" />    </Beans>

Second, the introduction of the properties file.

Method 1:

    <!---    <location = "classpath*:p roperties/ Db.properties "/>

Method 2:

Condition 1 Configures one:

    <id= "Propertyconfigurer"  class= " Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer ">        <  name= "Location"  value= "classpath*:d b/jdbc.properties" />    </ Bean >

Scenario 2 Configures multiple:

    <BeanID= "Propertyconfigure"class= "Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        < Propertyname= "Locations">            <List>                <value>Classpath:/opt/demo/config/demo-db.properties</value>                 <value>Classpath:/opt/demo/config/demo-db2.properties</value>             </List>        </ Property>    </Bean>

These properties are key-value key-value pairs, which can be obtained using ${xxx}.
