Spring reads a configuration file, injecting values into a static field

Resources/config/config-dev.properties

Es.ip.node=xxxxxxx
Cluster.name=xxxxxxx
Client.transport.sniff=xxxxxxx

Load Properties

<bean class= "Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >
    <property name= "Ignoreresourcenotfound" value= "true"/>
    <property name= "Locations" >
        <list>
            <value>classpath:config/config-${env}.properties</value>
        </list>
    </property>
</bean>

The bean that corresponds to the attribute

Import Org.springframework.beans.factory.annotation.Value;
Import org.springframework.stereotype.Component;

/**

**/
@Component
public class Esparams {
 Public StaticString Esipnode;
 Public StaticString clustername;
 Public StaticString Clienttransportsniff;

@Value ("${es.ip.node}")
public void Setesipnode (String esipnode) {
Esparams.esipnode = Esipnode;
}

@Value ("${cluster.name}")
public void Setclustername (String clustername) {
Esparams.clustername = clustername;
}

@Value ("${client.transport.sniff}")
public void Setclienttransportsniff (String clienttransportsniff) {
Esparams.clienttransportsniff = Clienttransportsniff;
}
}

Note: The color of the place, a little bit less error or write wrong, in addition to the automatic setter method to remove the modifier static  , otherwise spring cannot inject

You can now use esparams.xxx directly in any class for easy reference, such as Esparams.esipnode.
