编程创建春JNDI数据源(Programmatically creating a JNDI Data

我有了使用JNDI数据源定义一个Spring的基于Web的应用程序，我想创建一个独立的应用程序使用的bean。 我怎样才能在独立的应用程序编程方式创建JNDI条目和数据库性能？

<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/MyDS" />
</bean>

    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：

我想这样的事情，但我现在得到的错误“javax.naming.NoInitialContextException：需要环境或系统属性指定的类名”

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:

该org.springframework.test依赖具有用于通过支持SimpleNamingContextBuilder ：

// 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，
