how to retrieve the values in .properties into java using the spring and spring annotations

In this , u will see , how to get the values of .properties into java using spring annotations

in the spring application context xml file defined as below

      

    <util:properties id="pwdProperties"

        location="classpath:/PwdRules.properties" />

and define a properties file with the name PwdRules.properties, add any name value pair to this file

let consider we added like below

name=rby

now define a class , with the name . AppConfig.java , inside , write the below code

import org.springframework.beans.factory.annotation.Value;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.context.annotation.ImportResource;

@Configuration

//spring config that loads the properties file

@ImportResource("classpath:/login-connector.xml")

public class AppConfig {

/**

     * Using property 'EL' syntax to load values from the

     * jetProperties value

     */

    private @Value("#{pwdProperties[' name  ']}") String  name  ;

    

    /**

     * Create a jetBean within the Spring Application Context

     * @return a bean

     */

    public @Bean(name = "pwdBean")

    PwdBean pwdBean() {

    PwdBean bean = new PwdBean();

        bean.setName(name);

        return bean;

    }

 

}

define a bean class with the name

PwdBean.java and add one member field for that as, name and generate setter and getter for that 

and u can write the test case as below to test this

ApplicationContext ctx =

            new AnnotationConfigApplicationContext(AppConfig.class);

PwdBean bean = ctx.getBean(PwdBean.class);

System.out.print(bean.getPwdrule());
