java 读取配置文件

     前几天因为配置文件的事，线上的job挂掉了，使用的是spring加载配置文件方式。

spring配置如下

<span style="font-family:SimSun;font-size:14px;">	<bean id="propertyConfigurer" class="com.*.base.commons.system.DecryptPropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>test.properties</value>
				<value>api-test.properties</value>
			</list>
		</property>
	</bean></span>

     DecryptPropertyPlaceholderConfigurer类如下所示。

<span style="font-family:SimSun;font-size:14px;"><span style="font-family: Arial, Helvetica, sans-serif;">public class DecryptPropertyPlaceholderConfigurer extends<PropertyPlaceholderConfigurer {
	
	private Resource[] locations;
	private String fileEncoding;
	
    public void setFileEncoding(String fileEncoding) {
		this.fileEncoding = fileEncoding;
	}
	public void setLocations(Resource[] locations) {
        this.locations = locations;
    }
    public void loadProperties(Properties props) throws IOException {
    	String systemBasePath = "/etc/test/config";
        if (this.locations != null) {
            PropertiesPersister propertiesPersister = new DefaultPropertiesPersister();
            for (int i = 0; i < this.locations.length;
