MAVEN projects, Application-context.xml, db.properties files are placed in the Src/main/resources directory, Tomcat deployment project, src/main/ The configuration file under the Resources directory has the default location: {The project name is}/web-inf/classes, but spring is not found in the project root directory, so you can find it by specifying the CLASSPATH directory when configuring.

The solution is as follows:

<context:property-placeholder location= "classpath:db.properties"/>
