/**
 * #「Tp」Jackson Naming Strategy
 *
 * This component is `plugin` to resolving java bean specification in jackson here.
 *
 * zero framework support jooq engine as default, when the user want to do serialization for Jooq generated code, this
 * component could detect `getX` and `isX` to uniform identifying to replaced different java bean method here.
 *
 * 1. Situation 1: The type of boolean has been generated to `isX` as get bean method.
 * 2. Situation 2: The type of boolean has been kept in `getX` as get bean method.
 *
 * To uniform this kind of java bean get method specification, here zero provide small fix of naming resolution.
