讀取properties的幾種方式

• 方法①

public class ResourceUtil {
private static final ResourceBundle bundle = java.util.ResourceBundle
.getBundle("sysConfig");
public static final String getConfigByName(String name) {
String value = "";
try {
value = new String(bundle.getString(name).getBytes("iso8859-1"
 
),
"UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
return value;
}
}

• 方法②

public void testPro() throws IOException{
InputStream insss =this.getClass().getResourceAsStream("/conf/resources.properties");
Properties pss = new Properties();
pss.load(insss);
System.
 
out.println(pss.getProperty("IMAGE_SERVER_URL"));
}

• 方法③：

public void testPro() throws IOException{
InputStream insss =Object.class.getResourceAsStream("/conf/resources.properties");
Properties pss = new Properties();
pss.load(insss);
System.out.println(pss.getProperty("IMAGE_SERVER_URL"
 
));
}

• 方法④：

public class testProperties extends TestCase{
public void testPro() throws IOException{
Resource resource = new ClassPathResource("/conf/resources.properties");
Properties props = PropertiesLoaderUtils.loadProperties(resource);
System.out.println(props.getProperty("IMAGE_SERVER_URL"));
}
}

• 方法⑤

xml配置檔案中引入的：

        <context:property-placeholder location="classpath:conf/resources.properties" />  




       @Value("${IMAGE_SERVER_URL}")  

       private String IMAGE_SERVER_URL;

• 方法⑥：

ResourceBundle的方式 ，傳入一個inStream
ResourceBundle resource = new PropertyResourceBundle(inStream);

• 方法⑦：通過檔案讀取

InputStream inStream = new FileInputStream(new File("filePath"));

• 方法⑧：在servlet中：

InputStream in = context.getResourceAsStream("filePath");

方法⑨：ulr方式讀取

URL url = new URL("path");
InputStream inStream = url.openStream();

• 方法10讀取的方式：

Properties prop = new Properties();
prop.load(inStream);
String key = prop.getProperty("username");
String key = (String) prop.get("username");
