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;
