天易39----java与spring读取properties文件的方式

一：java方式读取（只能读取class文件下的properties文件）

private static String smsUrl;//url

static {
Properties prop = new Properties();
URL url= SendSMS.class.getResource("/sms.properties");
try {
prop.load(url.openStream());
smsUrl = prop.getProperty("smsUrl").trim();
} catch (Exception e) {
e.printStackTrace();
}
}

二：spring读取
1.读取class文件下的文件

static {
Resource resource = new ClassPathResource("/<span style="font-family: Arial, Helvetica, sans-serif;">sms.properties</span><span style="font-family: Arial, Helvetica, sans-serif;">");</span>
try {
Properties prop = PropertiesLoaderUtils.loadProperties(resource);
evaluateUrl=prop.getProperty("<span style="font-family: Arial, Helvetica, sans-serif;">smsUrl</span><span style="font-family: Arial, Helvetica, sans-serif;">").trim();</span>
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

2.读取web路径下的文件
<pre name="code" class="java">static {

Resource resource = new ClassPathResource("../config/config.properties");
try {
Properties prop = PropertiesLoaderUtils.loadProperties(resource);
evaluateUrl=prop.getProperty("jySystem.evaluateUrl").trim();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

tomcat下路径：
