spring - Tomcat 已启动但应用程序未运行

Question

我创建了一个 spring 应用程序并将其部署在 tomcat 服务器 (Tomcat v5.5 Server) 中。我检查了 tomcat 管理器，发现我的应用程序已列出。但是当我尝试运行我的应用程序时，我得到一个页面显示

**此程序无法显示网页

最可能的原因:您没有连接到 Internet。网站遇到问题。地址可能有打字错误。

您可以尝试: 检查您的互联网连接。尝试访问另一个网站以确保您已连接。

重新输入地址。**

我不知道我错过了什么。请帮我解决这个问题。

  <description>By default myfaces serializes the current view and saves it in session after view is rendered.
        In Pricing UI, values on the Page tags are bound to UIComponents on backing bean using "binding" attribute. Most of the components are created
        in the backing bean. When myfces serializes, it serializes the wrapped object under UIComponents, i.e HtmlDataTabl's value attribute, which are in Pricing UI case
        business objects which have a big graphs attached to it and you start getting "serialization" error

        Keep this pram-value to false to avoid serialization.</description>

Answer 1

我无法在问题中看到为此错误生成的确切日志消息。信息不足。

也没有提及您如何构建应用程序以及应用程序构建是否成功。我假设构建成功。

对于解决方法建议，如果您使用的是 pom.xml在您的应用程序和 Maven 中构建，请检查 <source>和 <target>你的申请？

<source>1.8</source> 
<target>1.8</target>

如果您的 pom 中提到的 java 版本与您系统的 java 版本不匹配，则可能会出现错误。也就是说，您的服务器可能会启动，但您的应用程序可能不会。

您还可以使用以下命令检查系统的 java 版本:

java -version
javac -version

两个版本应该匹配。如果您发现任何差异，请更改必要的内容并重建您的应用程序并重新启动服务器。
