java读取配置文件方法大全

1.读取Spring配置文件 文件位置项目/src/spring/spring-context.xml

ApplicationContext context = new ClassPathXmlApplicationContext("spring/spring-context.xml"); try{ TeacherDAO teacherDAO = (TeacherDAO) context.getBean("teacherDAO"); }catch (Exception e) { e.printStackTrace(); } }

2.在Spring配置文件中引入属性文件database-config.properties

<!-- spring加载数据库配置属性文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>database-config.properties</value> </list> </property> </bean>

3.在ibatis配置文件引入属性文件database-config.properties

<properties resource="database-config.properties" />

4.在java代码中加载属性文件database-config.properties

 try{ InputStream in = ConnectionManager.class.getClassLoader().getResourceAsStream("database-config.properties"); Properties properties = new Properties(); properties.load(in); System.out.println(properties.getProperty("java.mysql.server")); }catch (Exception e) { e.printStackTrace(); }
