MyBatis通用Mapper中的通用example(排序)详解

Example example = new Example(TerminalType.class);
//注意：排序使用的是列名
example.setOrderByClause("TT_PROVIDERID DESC");
//如果需要其他条件
//掌机类型名字
//条件查询使用的是属性名
example.createCriteria().andEqualTo("terminalName", "计量现场服务终端");
//厂商id大于3
// example.createCriteria().andGreaterThan("id",3);
List<TerminalType> terminalTypeList = terminalTypeService.selectByExample(example);

/**
     * 按照指定排序查询集合
     *
     * @param example - 条件
     * @return count
     */
    List<T> selectByExample(Object example);

 @Override
    public List<T> selectByExample(Object example) {
        return baseMapper.selectByExample(example);
    }

example.orderBy(BaseEntity.Field.GMTUpdate + " desc");
