Spring读取properties属性文件配置项遇到的问题

三个注意事项:
自动扫描
@Component
@Value

package test.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component("myConfig") // 这个一定要有
public class myConfig {

    @Value("${userAddress}") 
    private String address;

    @Value("${isUse}")
    private String isUser;

    public String getAddress() {
        return address;
    }

    public Boolean isUse() {
        if (isUser == null) {
            return false;
        }
        return Boolean.valueOf(isUser);
    }
}

【test.properties】文件内容
userAddress=192.168.1.110
isUse=true

<!-- 自动扫描的包名 这里要加入 myConfig类的包名 -->
    <context:component-scan base-package="demo;test.config"></context:component-scan>
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
	<property name="locations">
		<list>
			<value>classpath:test.properties</value>
			<value>classpath:test2.properties</value>
		</list>
	</property>
</bean>
