We might have some project specific configuration need to setup. The good approach to do this in Sprint is using ‘Proptries‘.
In resouces/applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <context:annotation-config /> <!-- Load app.properties file for use --> <context:property-placeholder location="app.properties" /> <bean name="customerRepository" class="com.pluralsight.repository.HibernateCustomerRepositoryImpl"></bean> <context:component-scan base-package="com.pluralsight" /> </beans>
In xml, we tell Sprint to looking for a file call ‘app.properties‘, which should located in the same folder of applicationContext.xml.
Inside app.properties file we can define some variables which related to the project:
dbUsername=mysqlusername
we can inject those variable into class:
public class HibernateCustomerRepositoryImpl implements CustomerRepository { @Value("${dbUsername}") private String dbUsername; @Override public List<Customer> findAll() { system.out.println(dbUsername) } }
****
We can also configure the ‘properties‘ by using Java configuration:
in com/pluralsight/AppConfig.java:
package com.pluralsight; import com.pluralsight.repository.CustomerRepository; import com.pluralsight.repository.HibernateCustomerRepositoryImpl; import com.pluralsight.service.CustomerService; import com.pluralsight.service.CustomerServiceImpl; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.support.PropertySourcesPlaceholderConfigurer; @Configuration @ComponentScan({"com.pluralsight"}) public class AppConfig { @Bean public static PropertySourcesPlaceholderConfigurer getPropertySourcesPlaceholderConfigurationn() { return new PropertySourcesPlaceholderConfigurer(); } }
