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;
