java.util.Date 到 java.sql.Date 的双向转换
java.sql.Date 是只包含 YYYY-MM-DD 的，而java.util.Date 包含完整的日期和时间。
// java.sql.Date 转 java.util.Date
例如[1]：
java.sql.Date sqlDate = java.sql.Date.valueOf("2010-09-15"); //SQL DATE
long time = sqlDate.getTime(); // getTime() 是各种日期相互转换的桥梁
java.util.Date utilDate = new java.util.Date(time);
//java.util.Date转java.sql.Date
例如[2]：
java.util.Date utilDate = new java.util.Date(); //获得系统当前时间
long time = utilDate.getTime(); // getTime() 是各种日期相互转换的桥梁
java.sql.Date sqlDate = new java.sql.Date(time); //SQL DATE
