xUtils系列之DbUtils-Check注解

Check注解定义:

@Target(ElementType.FIELD)@Retention(RetentionPolicy.RUNTIME)public @interface Check {    String value();}

DbUtils解析代码:

String check = ColumnUtils.getCheck(column.getColumnField());if (check != null) {    sqlBuffer.append(" CHECK(").append(check).append(")");}

用法:

@Column(column="age")@Check("age > 18")private int age;
