java – 以编程方式为Spring创建JNDI数据源

我有一个基于Spring的基于Web的应用程序,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？

diobjectfactorybean">
    sspathXmlApplicationContext 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();
    }
}

最佳答案

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

// 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,
