我做的一个网页项目，源代码没错，但我换了数据库，我该怎么改DB_URL =jdbc:mysql://http://127.0.0.1:3306/db_librarySys?user\=root&password\=1111&useUnicode\=true&characterEncoding\=utf-8才能使我的项目运行出来

数据库的地址ip还有账号密码是否正确。运行不出来，报错有什么提示。
你这个数据库连接URL看着就不对啊，http没有这个前缀的吧，更换的数据库名称一致吗？
我数据库名称和表都没有变，然后：http://localhost:8080/StrutsLibrarySystem/login.jsp这个是我要运行的登陆页面，出不来。
这个是我的java源代码：
package com.core;
import java.io.InputStream;
import java.sql.*;
import java.util.Properties;
/*数据库连接类*/
public class ConnDB {
public Connection conn = null;
public Statement stmt = null;
public ResultSet rs = null;
private static String propFileName = "/com/connDB.properties"; //指定资源文件保存的位置
private static Properties prop = new Properties();
private static String dbClassName ="com.mysql.jdbc.Driver";
private static String dbUrl =
"jdbc:mysql://127.0.0.1:3306/db_librarySys?user=root&password=123456789&useUnicode=true";
public ConnDB(){
try {
InputStream in=getClass().getResourceAsStream(propFileName);
prop.load(in); //通过输入流对象加载Properties文件
dbClassName = prop.getProperty("DB_CLASS_NAME"); //获取数据库驱动
dbUrl = prop.getProperty("DB_URL",
"jdbc:mysql://http://127.0.0.1:3306/db_librarySys?user=root&password=123456789&useUnicode=true");
}
catch (Exception e) {
e.printStackTrace(); //输出异常信息
}
}
public static Connection getConnection() {
Connection conn = null;
try {
Class.forName(dbClassName).newInstance();
conn = DriverManager.getConnection(dbUrl);
}
catch (Exception ee) {
ee.printStackTrace();
}
if (conn == null) {
System.err.println(
"警告: DbConnectionManager.getConnection() 获得数据库链接失败.\r\n\r\n链接类型:" +
dbClassName + "\r\n链接位置:" + dbUrl);
}
return conn;
}
/*
* 功能：执行查询语句
*/
public ResultSet executeQuery(String sql) {
try {
conn = getConnection();
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery(sql);
} catch (SQLException ex) {
System.err.println(ex.getMessage());
}
return rs;
}
/*
* 功能:执行更新操作
*/
public int executeUpdate(String sql) {
int result = 0;
try {
conn = getConnection(); //调用getConnection()方法构造Connection对象的一个实例conn
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
result = stmt.executeUpdate(sql); //执行更新操作
} catch (SQLException ex) {
result = 0;
}
return result;
}
/*
* 功能:关闭数据库的连接
*/
public void close() {
try {
if (rs != null) {
rs.close();
}
if (stmt != null) {
stmt.close();
}
if (conn != null) {
conn.close();
}
} catch (Exception e) {
e.printStackTrace(System.err);
}
}
}
这个项目的connDB.properties中的代码是：
DB_CLASS_NAME = com.mysql.jdbc.Driver
DB_URL =jdbc:mysql://127.0.0.1:3306/db_librarySys?user\=root&password\=123456789&useUnicode\=true&characterEncoding\=utf-8
这个是时我换了数据库软件后运行别的项目时的地址：http://lenovo-pc20160326:8080/baidutest/Score/Score_FrontQueryScore.action
然后我也不知道哪里出错了
