Bean初始化方案,初始化接口方案,Bean开发： public class User implements InitializingBean private String userName; public void afterPropertiesSet () throws Exception this.userName = Google; public String getUserName() return userName; public void setUserName(String userName) this.userName = userName; ,初始化接口方案,Bean的配置没有任何特殊的地方。如下： Eric ,初始化接口方案,业务逻辑： public static void main(String args) ApplicationContext ac = new FileSystemXmlApplicationContext( ./src/bean_initialization/init_interface/config/config.xml); / 取得一个实例 User user = (User) ac.getBean(userBean);System.out.println( user.getUserName() ); ,初始化方法方案,Bean开发： public class User private String userName; public void initMe() this.userName = BaiDu; public String getUserName() return userName; public void setUserName(String userName) this.userName = userName; ,初始化方法方案,Bean配置： Eric ,初始化方法方案,业务逻辑： public static void main(String args) ApplicationContext ac = new FileSystemXmlApplicationContext( ./src/bean_initialization/init_method/config/config.xml); / 取得一个实例 User user = (User) ac.getBean(userBean); System.out.println( user.getUserName() ); ,
