我收到了一个应用程序和各种各样的电子商店,我应该尝试运行然后修改一下。我在本地机器上使用Jetty运行它,然后转到http://localhost:8080/etnshop/(欢迎屏幕'),这似乎工作正常。但是,在单击了一个应该连接到数据库的按钮后,我收到了以下错误消息和stacktrace:
HTTP ERROR 500

出了什么问题?安装了MySQL,名称和pass与application.properties文件中的相同,并且MySQL服务正在运行,这是我找到的所有原因。是什么引起了这个?这里有一些类似的问题,但我不知道在哪里开始看到这些问题与这一问题之间的相似性。
答案 0 :(得分:0)
你是如何运行该应用程序的?你在使用中间件吗?如果是这样,您是否在中间件中配置了数据源?您是否已验证它是否正确连接到您的数据库并且名称与应用程序所需的名称相匹配?
如果它不是中间件,您如何将DB信息提供给应用程序?它是硬编码的吗?如果是,您是否验证了您的数据库是否与硬编码配置匹配?
答案 1 :(得分:0)
请注意,在错误堆栈中,如下所述
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown database 'etnshop'
确保您在Host =“jdbc:mysql:// localhost / etnshop”中提到的数据库;即etnshop是否正确。这里的数据库名称是CASE SENSITIVE!因此,如果您尝试使用“test2”等数据库名称而不是“Test2”进行连接,则可以获得
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown database 'test2'
也尝试使用端口号
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/etnshop", "root", "password");
答案 2 :(得分:0)
你能想到吗? 下面的代码列出了服务器上的所有(可见)数据库:
import java.sql.*;
public class mysqlTestMain {
public static void main(String[] args) {
Connection conn = null;
try {
String myConnectionString =
"jdbc:mysql://localhost:3306?" +
"useUnicode=yes&characterEncoding=UTF-8";
conn = DriverManager.getConnection(myConnectionString, "root", "beer");
Statement stmt = conn.createStatement();
stmt.execute("SHOW DATABASES");
ResultSet rs = stmt.getResultSet();
while (rs.next()) {
System.out.println(rs.getString(1));
}
rs.close();
stmt.close();
conn.close();
} catch (SQLException ex) {
ex.printStackTrace();
}
}
}
如果你得到了etnshop&#39;那么还有另一个问题。
