TokenInfoDTO tokenInfoDTO = TokenInfoDTO.builder().userId(userAuthRequestDTO.getUserId()). tokenType(userAuthRequestDTO.getTokenType()).deviceToken(deviceToken) .seq(System.currentTimeMillis()).build();是啥意思

这是一个使用了Lombok注解的Java代码，它创建了一个TokenInfoDTO对象。该对象包含以下字段：

- userId：用户ID
- tokenType：令牌类型
- deviceToken：设备令牌
- seq：一个随机的序列号，用于标识每个请求

这个代码使用了Lombok的@Builder注解，它会为TokenInfoDTO类自动生成一个带有所有字段的构造函数，以及一个名为builder()的静态方法，该方法可以用来创建TokenInfoDTO对象。在这个代码中，我们使用builder()方法来设置TokenInfoDTO对象的各个字段的值，并最终创建一个新的TokenInfoDTO对象。

这段代码是一个Java程序，其主要功能是校验用户的访问令牌（access token）是否合法。如果访问令牌为空，或者无法从缓存中获取到该用户的访问令牌，或者用户提交的访问令牌与缓存中的不一致，或者用户提交的设备标识与缓存中的不一致，都会抛出异常，提示用户访问令牌不合法或已失效。如果校验失败，该程序会记录错误日志并返回一个包含错误信息的数据对象。

//获取用户id String userId = UserAgent.get().getUserId(); //根据id拿到用户组织 Map<String, UserEo> userMapByUid = comDataComponent.getUserMapByUid(); String orgCode = userMapByUid.get(userId).getOrgCode(); //所有的行权限 列权限 List<SchemaRowRuleEo> schemaRowRuleList = comDataComponent.getSchemaRowRuleList(); List<SchemaColumnRuleEo> schemaColumnRuleList = comDataComponent.getSchemaColumnRuleList(); List<SchemaRowRule> userRowRuleList = new ArrayList<>(); DataPermissionSchema build = DataPermissionSchema.builder().build(); //设置行权限 根据用户id和用户组织去获取 for (SchemaRowRuleEo schemaRowRuleEo : schemaRowRuleList) { SchemaRowRule schemaRowRule = SchemaRowRule.builder().build(); if(StringUtils.isNotEmpty(schemaRowRuleEo.getRowPermissionUserList())){ List<String> userlist = JSONArray.parseArray(schemaRowRuleEo.getRowPermissionUserList(), String.class); if(userlist.contains(userId)){ BeanUtils.copyProperties(schemaRowRuleEo,schemaRowRule); userRowRuleList.add(schemaRowRule); } }else if(StringUtils.isNotEmpty(schemaRowRuleEo.getRowPermissionOrgList())){ List<String> orglist = JSONArray.parseArray(schemaRowRuleEo.getRowPermissionOrgList(), String.class); if(orglist.contains(orgCode)){ BeanUtils.copyProperties(schemaRowRuleEo,schemaRowRule); userRowRuleList.add(schemaRowRule); } } } build.setSchemaRowRuleList(userRowRuleList);代码优化及原因

可以将循环中的if语句提取出来，避免重复代码。同时，使用stream流简化代码，并提高代码可读性。代码优化后如下：

String userId = UserAgent.get().getUserId();
Map<String, UserEo> userMapByUid = comDataComponent.getUserMapByUid();
String orgCode = userMapByUid.get(userId).getOrgCode();
List<SchemaRowRuleEo> schemaRowRuleList = comDataComponent.getSchemaRowRuleList();
List<SchemaColumnRuleEo> schemaColumnRuleList = comDataComponent.getSchemaColumnRuleList();

List<SchemaRowRule> userRowRuleList = schemaRowRuleList.stream()
    .filter(schemaRowRuleEo -> {
        List<String> userList = JSONArray.parseArray(schemaRowRuleEo.getRowPermissionUserList(), String.class);
        List<String> orgList = JSONArray.parseArray(schemaRowRuleEo.getRowPermissionOrgList(), String.class);
        return userList.contains(userId) || orgList.contains(orgCode);
    })
    .map(schemaRowRuleEo -> {
        SchemaRowRule schemaRowRule = SchemaRowRule.builder().build();
        BeanUtils.copyProperties(schemaRowRuleEo, schemaRowRule);
        return schemaRowRule;
    })
    .collect(Collectors.toList());

DataPermissionSchema build = DataPermissionSchema.builder().build();
build.setSchemaRowRuleList(userRowRuleList);

优化后的代码更加简洁易读，使用stream流可以避免重复代码，同时也可以提高代码的执行效率。
