java - 无法在 java 程序中创建初始上下文

Question

public static void setupInitialContext() {
    try {
        System.out.println("Loading Initial Context");
        NamingManager.setInitialContextFactoryBuilder(new InitialContextFactoryBuilder() {

            @Override
            public InitialContextFactory createInitialContextFactory(Hashtable<?, ?> environment)
                    throws NamingException {
                return new InitialContextFactory() {
                    @Override
                    public Context getInitialContext(Hashtable<?, ?> environment) throws NamingException {
                        InitialContext context = null;

                        try {
                            context = new MockLocalContext();
                        } catch (Exception ex) {
                            ex.printStackTrace();
                        }

                        return context;
                    }

                };
            }

        });
        System.out.println("Loaded Initial Context");
    } catch (NamingException ne) {
        ne.printStackTrace();
    }
}

    public static void main(String[] args) throws NamingException {
    setupInitialContext();
    InitialContext context = new InitialContext();
    context.lookup(DS_ORACLE);
}

MockLocalContext 是一个扩展 javax.naming.InitialContext 类的类。这是创建 InitialContext 对象时的错误。

我得到以下堆栈跟踪：

它与具有相同内容的多行内容一致，我只是对其进行了修剪以适合此处。谢谢！

看起来您的 MockLocalContext 启动了一个 InitialContext，它试图获取默认的初始上下文，即 MockLocalContext，它启动 MockLocalContext，它启动一个 InitialContext，依此类推。
