sql预期：

SELECT
	* 
FROM
	BUILDING_INFO 
WHERE
	( CITY_ID = 7 ) 
	AND ( BUILD_NAME LIKE '%高标大厦%' OR BUILD_ADDR LIKE '%高标大厦%' ) 
ORDER BY
	CITY_ID DESC

java代码实现：

		ErpBuildingInfoExample example = new ErpBuildingInfoExample();
        example.setShardCityId(7);
        example.setOrderByClause(" CITY_ID DESC");
        ErpBuildingInfoExample.Criteria criteria = example.createCriteria();
        criteria.andCityIdEqualTo(Short.valueOf("7"));
        //关键字
        if (StringUtil.isNotBlank(matchQueryParam.getPkNameOrAddress())) {
            criteria.andBuildNameOrAddrLike(matchQueryParam.getPkNameOrAddress());
        }
        PageHelper.startPage(matchQueryParam.getPageOffset(), matchQueryParam.getPageRows());
        List<ErpBuildingInfo> erpBuildingInfos = buildingInfoMapper.selectByExample(example);

重点：example自定义添加一个方法：
这里的语句因为包含的%模糊查询，避免有恶意的输入%字符进行SQL注入，因此使用ESCAPE过滤保障安全

public Criteria andBuildNameOrAddrLike(String value) {
            addCriterion("((BUILD_NAME like '%/" + value + "%' ESCAPE '/') or (BUILD_ADDR like '%/" + value + "%' ESCAPE '/'))");
            return (Criteria) this;
        }
