Unable to complete the scan for annotations for web application

Unable to complete the scan for annotations for web application

Unable to complete the scan for annotations for web application [/CMIG] due to a StackOverflowError. Possible root causes include a too low setting for -Xss and illegal cyclic inheritance dependencies. The class hierarchy being processed was [org.bouncycastle.asn1.ASN1OutputStream->org.bouncycastle.asn1.DEROutputStream->org.bouncycastle.asn1.ASN1OutputStream]

 

 

-xss 调大

 

tomcat 7 扫注解

org.bouncycastle.asn1.ASN1OutputStream 这个包有问题

把这个包过滤掉

在 tomcat /conf/catalina.properties 文件中

找到

tomcat.util.scan.DefaultJarScanner.jarsToSkip=\

这一句

改成

tomcat.util.scan.DefaultJarScanner.jarsToSkip= bcprov*.jar\

主要报错点：

Unable to complete the scan for annotations for web application [/gbp] due to a StackOverflowError. Possible root causes include a too low setting for -Xss and illegal cyclic inheritance dependencies. The class hierarchy being processed was [org.bouncycastle.asn1.ASN1EncodableVector->org.bouncycastle.asn1.DEREncodableVector->org.bouncycastle.asn1.ASN1EncodableVector

在网上搜索了一下，很多说是修改catalina.properties的配置文件，但就算是解决了问题，也不是最好的办法。
这个问题的根本原因是jar包冲突，导致堆栈溢出。所以应该考虑的是如何解决jar依赖问题。

从org.bouncycastle.asn1.ASN1Boolean这个类入手。查看系统中·ASN1Boolean`出现在了两个包中:

<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk16</artifactId>

和

<groupId>org.bouncycastle</groupId>
<artifactId>bcprov-jdk15on</artifactId>

所以根据实际情况，去除一个即可。

 

$word = new COM(

$word = new COM("word.application") or die("Unable to instantiate Word");

$word = new COM("word.application") or die("Unable to instantiate Word");


以上代码为什么在 PHP 环境上不能执行？？？

如何解决ActionController :: RoutingError没有路由与[GET]“ / vendor / assets / stylesheets / bootstrap.min.css”匹配 app / assets / stylesheets / application.css： app / assets / javascript / application.js： app / views / layout / application.html.erb： app / j

我正在Rails上执行此应用程序，页面加载正常，但在控制台中显示：

Started GET "/vendor/assets/stylesheets/bootstrap.min.css" for ::1 at 2020-08-17 09:09:51 -0500

Started GET "/vendor/assets/javascripts/bootstrap.min.js" for ::1 at 2020-08-17 09:09:51 -0500
ActionController::RoutingError (No route matches [GET] 
"/vendor/assets/stylesheets/bootstrap.min.css"):
ActionController::RoutingError (No route matches [GET] 
"/vendor/assets/javascripts/bootstrap.min.js"):

在我的供应商文件夹中，我同时拥有文件夹，javascript和样式表，并分别位于各自的bootsrtrap.min中。 即使在application.html.erb中，我也有以下内容：

  <link href="vendor/assets/stylesheets/bootstrap.min.css" rel="stylesheet">
  <%= csrf_Meta_tags %>
  <%= stylesheet_link_tag    ''application'',media: ''all'',''data-turbolinks-track'': ''reload'' %>
  <%= javascript_include_tag ''application'',''data-turbolinks-track'': ''reload'' %>

</head>
<body>

  <!-- Navigation -->
  <nav>
    <div>
      <ahref="#">Instagram Clone</a>
      <buttontype="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
        <span></span>
      </button>
      <divid="navbarResponsive">
        <ul>
          <li>
            <ahref="#">Home
              <span>(current)</span>
            </a>
          </li>
          <li>
            <ahref="#">About</a>
          </li>
          <li>
            <ahref="#">Services</a>
          </li>
          <li>
            <ahref="#">Contact</a>
          </li>
        </ul>
      </div>
    </div>
  </nav>

  <!-- Page Content -->
  <div>
    <div>
      <div>
        <%= yield %>
      </div>
    </div>
  </div>

  <!-- Bootstrap core JavaScript -->
  <!--<script src="vendor/jquery/jquery.slim.min.js"></script>-->
  <script src="vendor/assets/javascripts/bootstrap.min.js"></script>
    
</body>
</html>

在js和CSS这两个应用程序文件中，我都放置了“ require bootsrtrap.min”，即使该错误仍然出现在控制台中。 会是什么？

解决方法

RoR不使用目录作为文件夹结构指示。因为有资产装载者。您应该将5s或更少的css导入application.css中，并将js导入application.js中。并使用自己的助手添加捆绑文件：

1。用纱安装靴子

yarn add bootstrap @popperjs/core jquery

或

npm i bootstrap @popperjs/core jquery

栏位不超过5

2。在Assets Pipeline中导入文件

app / assets / stylesheets / application.css：

//...
require bootstrap/dist/css/bootstrap.min
//...

但是，如果需要，我建议使用SCSS并仅导入所需的样式。

app / assets / javascript / application.js：

//...
//= require jquery
//= require @popperjs/core
//= require bootstrap/dist/js/bootstrap.min
//...

3。在布局中导入资产

app / views / layout / application.html.erb：

<head>
...
  <%= stylesheet_link_tag ''application'',media: ''all'' %>
</head>
<body>
...
  <%= javascript_include_tag ''application'' %>
</body>

使用webpack滚动6

2。在application.scss和application.js中导入Bootstrap

app / javascript / stylesheets / application.scss：

//...
import ''bootstrap''
//...

app / javascript / packs / application.js：

import ''jquery''
import ''popper.js''
import ''bootstrap''
import ''../stylesheets/application''

3。在布局中导入捆绑包

<head>
...
  <%= stylesheet_pack_tag ''application'',media: ''all'',''data-turbolinks-track'': ''reload'' %>
  <%= javascript_pack_tag ''application'',''data-turbolinks-track'': ''reload'' %>
</head>

之后，您应该可以在所有应用程序中使用引导程序！

,

[解决方案]因此，在我的HTML（application.html.erb）内部，我有两个对js和css文件的调用：

<script src="assets/javascripts/bootstrap.min.js"></script>
  <%= javascript_include_tag ''application'',''data-turbolinks-track'': ''reload'' %>       
<link href="assets/stylesheets/bootstrap.min.css" rel="stylesheet">
  <%= csrf_meta_tags %>
  <%= stylesheet_link_tag    ''application'',''data-turbolinks-track'': 
  ''reload'' %>

正如您在上面看到的那样，在使用javascript的情况下，我有一个使用脚本的调用，而另一个使用了的调用，两者都造成了问题，所以您只需要评论一个，我就对该脚本进行评论对于我的java文件和CSS文件，一个。 像这样：

  <!--<link href="assets/stylesheets/bootstrap.min.css" rel="stylesheet">-->
    <!--<script src="assets/javascripts/bootstrap.min.js"></script>-->

对我来说，解决了这个问题，我真的尝试了所有事情，这就是解决方案哈哈。
