Spring is set in properties file by @value, and differs from @value # and $

Spring gets the value method of properties

Configuring in Spring.xml

Oddly enough, the Context-param loaded spring.xml cannot use ${xxx}

Must be handed over to Dispatcherservlet management springmvc.xml to use?

To give Springmvc dispatcherservlet to scan, instead of Spring listener Contextloaderlistener to scan, it can be more convenient to use "${xxx" to inject.

1. Use $ to get properties

@Value ("${user.name}")

Private String UserName;

<location= "Classpath*:info/info.properties"/>
<Beanclass= "Org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">    < Propertyname= "Order"value= "1" />    < Propertyname= "Locations">        <List>            <value>Classpath:info/info.properties</value>        </List>    </ Property></Bean>

2. Use #获取属性

@Value ("#{user.name}")

Private String UserName;

<BeanID= "prop"class= "Org.springframework.beans.factory.config.PropertiesFactoryBean">         < Propertyname= "Locations">             <Array>                 <value>Classpath:configure.properties</value>             </Array>         </ Property> </Bean>
