Question

我关注此文件 -

http://spring.io/guides/gs/relational-data-access/#scratch

设置数据源后，创建一个jdbcTemplate -

SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
        dataSource.setDriverClass(com.mysql.jdbc.Driver.class);
        dataSource.setUsername("username");
        dataSource.setUrl("jdbc:mysql:/uel.to.connect.the.db");
        dataSource.setPassword("password");
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

当我尝试进行选择查询时 -

List<GameBean> results = jdbcTemplate.query("select * from Games",
                new RowMapper<GameBean>() {
                    @Override
                    public GameBean mapRow(ResultSet rs, int rowNum) throws SQLException {
                        GameBean gb = new GameBean();
                        gb.setGameId(rs.getInt("GameId"));
                        gb.setGameName(rs.getString("GameName"));
                        return gb;
                    }
                });

我收到错误提及＆＃34;无法获得JDBC连接;＆＃34;

有人可以建议我在这里失踪吗？

您必须正确配置对MySql架构的访问：

java.sql.SQLException: Access denied for user 'social_devuser'@'10.55.200.1' (using password: YES)

也许您在配置中指定了错误的用户名/密码，或者您没有从10.55.200.1 ip address授予对该用户的访问权限

使用JDBC和Spring访问关系数据时嵌套的Servlet异常
