"Spring" about the location path settings


1, relative path can be set through classpath and classpath*, such as: <bean id= "Sqlsessionfactory" class= " Org.mybatis.spring.SqlSessionFactoryBean ">
<property name= "DataSource" ref= "DataSource"/>
<property name= "configlocation" value= "Classpath:sqlMapConfig.xml" ></property>
<property name= "mapperlocations" value= "Classpath*:mapper/**/*mapper.xml" ></property>
</bean>
<context:property-placeholder location= "Classpath:/jdbc.properties"/>
For the difference between classpath and classpath*, please refer to: 1. Both Classpath and classpath* can load resource files under the entire classpath (including inside the jar package). 2.classpath only returns the first matching resource, the lookup path is the priority in the project where the resource file exists, and then the jar package is found. 3. The file name contains a wildcard resource (if spring-*.xml,spring*.xml), if the root directory is "", classpath cannot load any resources, and classpath* can be loaded into classpathdirectories that can be matchedResources in a jar package, but cannot be loaded into the

It can also be set by file Plus system variables, such as in Catalina.sh/catalina.bat (or JBoss run.sh/run.bat) file in Tomcat6 bin, or after java--opts.

-djdbc.properties=d:/tomcat6/bin/db.properties

<property name= "Locations" value= "file:#{systemproperties[' Jdbc.properties ']}"/>
