<bean id="Mybean" class="Bean">
<property name="config" ref="dev"/>
</bean>
<bean id="dev" class="Dev">
<property name="x" ref="Dev1">
<property name="y" ref="Dev2">
<property name="z" ref="Dev3">
</bean>
<bean id="stag" class="Dev">
<property name="x" ref="Stag1">
<property name="y" ref="Stag2">
<property name="z" ref="Stag3">
</bean>
In the above scenario, the config property in the bean MyBean change from environment to environment. At the time of dev, reference of config change to dev. And in staging, the reference change to stag. The problem comes at the time of checked in the spring file. We have to analyze everytime the reference of config before checked in. If the reference of config with the value of dev checked in, we might have to explain a lot of questions.
Is there any solution to solve to make it automate?
Note: Spring version is 2.0.1
462
String hello(String name) { return "Hello, " + name; } } // and later in your application AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(ApplicationConfiguration. class); String helloCat = (String) context. getBean("hello", "Cat"); String helloDog = (String) context.
Instead, when you start up your application, Spring Boot dynamically wires up beans and settings and applies them to your application context. Building applications with Spring Boot is really fast, especially for web applications.
Use the PropertyPlaceholderConfigurer from Spring, and remove an unused bean :
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>env.properties</value>
</property>
</bean>
<bean id="Mybean" class="Bean">
<property name="config" ref="config"/>
</bean>
<bean id="config" class="Config">
<property name="x" ref="${x}">
<property name="y" ref="${y}">
<property name="z" ref="${z}">
</bean>
and the env.properties file contains the following properties :
x=Dev1
y=Dev2
z=Dev3
or
x=Stag1
y=Stag2
z=Stag3
