以编程方式为Spring创建JNDI DataSource

我有一个现有的基于Spring的Web应用程序，它具有使用JNDI定义的数据源，我正在尝试创建一个独立的应用程序来使用bean。 如何在独立应用程序中以编程方式创建JNDI条目和数据库属性？

   public static void main(String[] args) { // this throws an error since the JNDI lookup fails - can I programmatically define the database properties here? ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); UserService userService = ctx.getBean(UserService.class); User user = userService.findUserById("jdoe"); System.out.println("display name: " + user.getDisplayName()); } 

编辑：

我尝试过类似的东西，但现在收到错误“javax.naming.NoInitialContextException：需要在环境或系统属性中指定类名”

 public static void main(String[] args) { setupJNDI(); ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); UserService userService = ctx.getBean(UserService.class); User user = userService.findUserById("jdoe"); System.out.println("display name: " + user.getDisplayName()); } private static void setupJNDI() { InitialContext ic; try { ic = new InitialContext(); ic.createSubcontext("java:"); ic.createSubcontext("java:/comp"); ic.createSubcontext("java:/comp/env"); ic.createSubcontext("java:/comp/env/jdbc"); SQLServerConnectionPoolDataSource myDS = new SQLServerConnectionPoolDataSource(); opaDS.setServerName("myserver"); opaDS.setPortNumber(1433); opaDS.setUser("user"); opaDS.setPassword("password"); ic.bind("java:/comp/env/jdbc/MyDS", myDS); } catch (NamingException e) { e.printStackTrace(); } } 

Answer 1

org.springframework.test依赖项通过SimpleNamingContextBuilder支持它：

 // First create the mock JNDI tree and bind the DS SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder(); DataSource ds = new ComboPooledDataSource(); ds.setDriverClass( ... ); // etc. for uid, password, url builder.bind( "java:comp/env/jdbc/MyDS" , ds ); builder.activate(); // Then create the Spring context, which should now be able // to resolve the JNDI datasource ApplicationContext context = new ClassPathXmlApplicationContext( "..." ); 

这应该工作。

干杯，
