我在Linux Mandriva上安装了Tomcat 7和MySQL数据库，但是部署在容器中的应用无法连接。
我写了两个简单的测试，当从客户端运行它们时，我得到了连接 -
public class TestHibernate {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
User user = new User();
user.setName("userName");
user.setPassword("userPassword");
Session session = HibernateUtil.
getSessionFactory().openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
session.close();
}
}
HibernateUtil 的一部分 -
...
cnf.setProperty("hibernate.connection.url", "jdbc:mysql://ip:3306/gibrid");
cnf.setProperty("hibernate.connection.username", "java");
cnf.setProperty("hibernate.connection.password", "java");
...
Jdbc 测试-
public class TestJdbc {
public static void main(String[] args) {
Connection conn = null;
String url = "jdbc:mysql://ip:3306/";
String dbName = "gibrid";
String driver = "com.mysql.jdbc.Driver";
String userName = "java";
String password = "java";
try {
Class.forName(driver).newInstance();
conn = DriverManager.getConnection(url+dbName,userName,password);
System.out.println("Connected to the database");
conn.close();
System.out.println("Disconnected from database");
} catch (Exception e) {
e.printStackTrace();
}
}
}
在这些情况下，我可以获得连接并可以使用数据库。但是当我从客户端浏览器请求时，我会超时。这是为什么？ 如果能提供信息，我将不胜感激。
这是 catalina.out -

最佳答案
我不熟悉 Hibernate，所以我不知道这是否相关:
“未找到 hibernate.properties”
“在 URL 上使用驱动程序:com.mysql.jdbc.Driver:jdbc:mysql://---ip here----/gibrid”
IP 和端口是否与您测试程序中的相同？
这blog提示 C3PO 的配置问题。一条评论暗示了 Mysql 和 C3PO 之间不同的超时设置。
关于mysql - Linux Mandriva : Tomcat can not get MySQL database connection, 为什么？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12934384/
