Hikaricp 连接池的两种简单配置办法

一种是通过HikariConfig

        HikariConfig config = new HikariConfig();
        config.setJdbcUrl("jdbc:mysql://localhost:3306/test");
        config.setUsername("root");
        config.setPassword("root");
        config.addDataSourceProperty("cachePrepStmts", "true");
        config.addDataSourceProperty("prepStmtCacheSize", "250");
        config.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");

        HikariDataSource ds = new HikariDataSource(config);
        fromJdbcTemplate = new MyJdbcTemplate(ds);

另一中是直接配置

       HikariDataSource toDataSource = new HikariDataSource();
        toDataSource.setJdbcUrl("jdbc:mysql://localhost:3306/test");
        toDataSource.setUsername("root");
        toDataSource.setPassword("root");
        toJdbcTemplate = new MyJdbcTemplate(toDataSource);
