code: public static String whereLogicDelete(Class<?> entityClass, boolean isDeleted) {
          String value = logicDeleteColumnEqualsValue(entityClass, isDeleted);
          return "".equals(value) ? "" : " AND " + value;
      }
docs: 逻辑删除的where条件，没有逻辑删除注解则返回空字符串
  <br>
  AND column = value
  
  @param entityClass
  @param isDeleted   true：已经逻辑删除，false：未逻辑删除
  @return
