xxx.properties获取方法

1、手动获取加载

Locale locale = Locale.getDefault();
ResourceBundle localResource = ResourceBundle.getBundle("config", locale);
String ztreejdbc = localResource.getString("jdbc_url");
String ztreename = localResource.getString("jdbc_username");
String ztreepassword = localResource.getString("jdbc_password");

2、spring 

<context:property-placeholder location="classpath*:/*.properties" ignore-unresolvable="true"/>

　　@Value("#{configProperties['jdbc.jdbcUrl']}")  

　　private String jdbcUrl ;

3、

@PropertySource("/conf/jdbc.properties")
public class DataSourceConfig {
	
	@Value("${jdbc.driverClass}") String driverClass;
	@Value("${jdbc.url}") String url;
	@Value("${jdbc.user}") String user;
	@Value("${jdbc.password}") String password;


4、

public static String getDirPath() {

        Resource resource = null;

        Properties props = null;

        String driverClass = null;

        try {

            resource = new ClassPathResource("/data.properties");

            props = PropertiesLoaderUtils.loadProperties(resource);

            driverClass= (String) props.get("wingPath");

        } catch (IOException e) {

            e.printStackTrace();

        }

        return driverClass;

         

    }
