在JavaEE中隐式关闭上下文

我试图在JavaEE8（Java11）中实现以下代码，以访问Wildfly 20中的数据源。目标是隐式关闭JNDI上下文和SQL连接：

try (InitialContext context = new InitialContext();
     Connection conn = ((DataSource) context.lookup(pool)).getConnection()) {
    
      // use the connection

} 
catch (NamingException e) {
    logger.error(e.getMessage());
} 
catch (SQLException e) {
    logger.error(e.getMessage());
}

问题是上下文不可关闭，因为我得到了编译错误：

The resource type InitialContext does not implement java.lang.AutoCloseable

---

我试图避免添加

最后

来关闭上下文，有没有办法做到这一点？

尝试使用资源仅适用于

可自动关闭的对象。不使用
finally
的一种方法是将
InitialContext
包装在一个实现
AutoCloseable
的包装器中，该包装器在其
close（）方法中执行必要的操作。大概是这样的：

public class AutoCloseableWrapper implements AutoCloseable {

    private final InitialContext context;

    public AutoCloseableWrapper(InitialContext context) {
        this.context = context;
    }

    public InitialContext getContext() {
        return this.context;
    }

    @Override
    public void close() throws Exception {
        this.context.close();
    }
}

try (AutoCloseableWrapper wrapper = new AutoCloseableWrapper(new InitialContext());
     Connection conn = ((DataSource) wrapper.getContext().lookup(pool)).getConnection()) {

    // ...
}

像这样使用它：

public class AutoCloseableWrapper implements AutoCloseable {

    private final InitialContext context;

    public AutoCloseableWrapper(InitialContext context) {
        this.context = context;
    }

    public InitialContext getContext() {
        return this.context;
    }

    @Override
    public void close() throws Exception {
        this.context.close();
    }
}

try (AutoCloseableWrapper wrapper = new AutoCloseableWrapper(new InitialContext());
     Connection conn = ((DataSource) wrapper.getContext().lookup(pool)).getConnection()) {

    // ...
}
