How do I connect to the database(MYSQL) in connection bean using JSF to retrieve its contents. Also please let me know how do I configure the web.xml file?

To get connected to mysql:
要连接到 mysql:
public void open() {
try {
String databaseName = "custom";
String userName = "root";
String password = "welcome";
//
String url = "jdbc:mysql://localhost/" + databaseName;
Class.forName("com.mysql.jdbc.Driver").newInstance();
connection = DriverManager.getConnection(url, userName, password);
} catch (Exception e) {
System.out.println("Not able to connect");
}
}
In this case there is nothing to change in web.xml.But you to add this in pom.xml
在这种情况下,web.xml 中没有什么可更改的。但是您可以在 pom.xml 中添加它
<dependency>
<groupId>groupId = mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.6</version>
</dependency>
This was working successfully.
这是成功的工作。

If you are using JSF, that website can be a good place to find solutions for common problems. There are great and complete examples.
如果您使用的是 JSF,那么该网站可能是查找常见问题解决方案的好地方。有很好的和完整的例子。
Anyway, JSF is a framework that manages the view and the controller layers. For the model layer and the access to a database there are not big difference if you use JSF or any other java web framework that manages the view/controller part of your application.
总之,JSF 是一个管理视图层和控制器层的框架。对于模型层和对数据库的访问,如果您使用 JSF 或任何其他管理应用程序视图/控制器部分的 Java Web 框架,则没有太大区别。

Here is an example using Hibernate and HSQL- but the basic ideas of separating the db stuff out should be valid and it includes a configured web.xml.
这是一个使用 Hibernate 和 HSQL的示例- 但将 db 内容分离出来的基本思想应该是有效的,它包括一个配置好的 web.xml。
