Spring — java.util.Properties DI Parameters | Code Factory

Spring Tutorial Index Page: Link

  • For Property, inside dtd based configuration we can pass required key-value pairs.
<bean id="" class="">
<property name="">
<prop key="fname">ABC</prop>
  • For Map we use <entry> tag but for Property we use <props> tag.

Create Java Project

  • Open Eclipse
  • Go to File -> New -> Others… -> Java Project
  • Create DI-Properties project
  • Right click on project -> Build Path -> Configure Build Path -> Libraries tab -> Add External JARs
    - commons-logging-X.X.jar
    - spring-beans-X.X.X.jar
    - spring-context-X.X.X.jar
    - spring-core-X.X.X.jar
    - spring-expression-X.X.X.jar
  • * You can find dtd information from spring-beans-X.X.X.jar -> org -> springframework -> beans -> factory -> xml -> spring-beans.dtd (line no 36 & 37)
