小编Sha*_*mad的帖子

刚开始,我是apache camel的新手.我有一个spring boot(MVC)+ mongodb项目已经运行正常,当我尝试将它与apache camel集成时,我在控制台上遇到异常.根据我对异常弹簧启动的理解,@Component当我@ComponentScan(basePackages="packagePath")在项目中的其他任何地方使用时,我试图说我不能在camel Route文件上使用默认注释,因为它是一个MVC架构,我有Controller,Service&Repository,我不能忽视,请帮我解决这个问题.

控制台例外

我在相对布局中包含了一个进度条，但是它在布局后面运行。有什么办法可以使它显示在页面加载时显示的前面。

我不知道为什么会这样显示。

我试图在我的 spring 项目中配置 swagger，但是点击“ http://localhost:8080/api-docs ”说“404 Not Found”。

我创建了一个主要活动，其中有一个片段容器，我在导航菜单选项选择中替换其中的许多片段。它工作正常，但问题是：

1. 当我单击导航项两次时，打开了两个相同的片段，我必须按两次后退按钮才能返回。
2. 当所有片段在按下后被销毁时，我看到一个空白页面（我猜这可能是主活动页面）。

我正在尝试调试我的代码,eclipse没有在调试模式下说明,但它在正常启动时工作正常.

以下是我在eclipse弹出窗口中获得的异常:

当我查看控制台时,一切看起来都很好,请看看....

我真的很惊讶，代码发生了什么，gridView 项目每次都在第 11 个位置显示重复，有时也在第 12 个位置显示重复。

我是新手,我很难知道如何计算10 ^ 5(10到5的功率).

如果这是一个Java代码,我会写的这

但在这种情况下,我也没有在网上找到任何例子.

任何线索!
