How to set properties of a bean from properties file.......

This can be accomplished by PropertyPlaceholderConfigurer class

Bean.java
package props;

public class Bean {
private String value1, value2;
public String getValue1() {
return value1;
}
public void setValue1(String value1) {
this.value1 = value1;
}
public String getValue2() {
return value2;
}
public void setValue2(String value2) {
this.value2 = value2;
}
}

ApplicationResource.properties

context.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
