java - HTTP 状态 404 : The requested resource is not available/Tomcat7

Question

我已经在我的 java 应用程序上工作了几天。该项目是一个简单的 Spring、Hibernate、jsf、mysql 集成，我在 Eclipse 上运行。该程序的目的是在 MySQLWorkbench 上添加一个人(id、名字、姓氏、性别、年龄等)数据库并在服务器上运行它。我使用 Spring4、Hibernate4 和 Eclipse Luna 作为工具。我将项目构建为maven。数据库目前运行良好，当我运行主类时我可以添加新行。但是当它在服务器上运行它时，我失败了。我在 Youtube 上观看了一些教程，看到了一些使用 Tomcat7 的有效方法。在我第一次尝试运行 java 应用程序时，我应用了以下步骤:

1-我通过右键单击 Project Explorer 上的 Servers 文件夹来创建一个新服务器(Tomcatv7.0 Server)。

2-我添加了我的项目，通过右键单击服务器并选择“添加和删除”在服务器上配置它

3-我再次右键单击项目“运行方式”-->“在服务器上运行”。

顺便说一下，我在控制台上看到了一个输出:

当然，当我在浏览器中输入 localhost:8083 时，出现了“HTTP Status 404:请求的资源不可用”错误。

在这里和其他网站上搜索类似的问题，我根据给定的答案修改了服务器属性。例如，我创建了一个新服务器；将服务器位置更改为“使用tomcat安装(控制Tomcat安装)”，并通过右键单击属性部分切换位置。

进行此修改后运行后，我在浏览器上遇到相同的错误，并在控制台上出现以下输出:

我的项目在这里:https://github.com/fsel/Spring-Hibernate-JSF-MySQL-Eclipse-Integration

项目结构如下:

我知道我已经像傻瓜一样解释了我的工作，但我已经厌倦了解决这个问题。也许，我的 web.xml 文件或 maven 依赖项有问题。但我尝试了不同的方法来编辑它们同样的错误，再次出现!

你能解释一下我做错了什么吗？感谢您的帮助!

Answer 1

错误表示无法找到实体类 Person。

java.lang.ClassNotFoundException:com.hibernate.data.Person

此外，改变来自:http://hibernate.sourceforge.net/至:http://www.hibernate.org/dtd/在 hibernate 配置文件中。

我注意到的另一个问题，

您正在使用

class="org.springframework.orm.hibernate4.HibernateTransactionManager"以及

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"

一个类来自 hibernate3，另一个类来自 hibernate4。这可能是您出现问题的原因。坚持使用 spring orm 的一个版本。
