sql 语句
QueryRunner runner = new QueryRunner(C3P0Utils.getDataSource());
String sql = "select * from product where pname like ?";
return runner.query(sql, new BeanListHandler<Product>(Product.class), "%"+proName+"%");
注意乱码问题
要在 c3p0.xml 中设置
<property name="jdbcUrl">jdbc:mysql:///17store??useUnicode=true;characterEncoding=UTF-8</property>
