QueryWrapper 不差用的

代码

QueryWrapper apply拼接sql查询

QueryWrapper<YwTerminalDistribution> queryWrapper = QueryGenerator.initQueryWrapper(ywTerminalDistribution, req.getParameterMap());
queryWrapper.apply("actual_start_time <= {0} AND actual_end_time >= {0}",time);

QueryWrapper or使用

int count = zctMatchedBaseService.count(new QueryWrapper<ZctMatchedBase>().eq("id", id).and(wrapper -> wrapper.eq("is_weld", "1").or().eq("is_detection", "1")));

QueryWrapper 查询返回单个字段

String usernameString = sysUserService.list(new QueryWrapper<SysUser>().in("id", userIds))
                        .stream()
                        .map(SysUser::getUsername)
                        .collect(Collectors.joining(","));
