代码缩进与格式

1.数据库查询时候的换行写法

标准友好的写法

List<AlarmRuleNew> dbAlarmRules = mapperContext.getAlarmRuleNewMapper().selectList(new QueryWrapper<AlarmRuleNew>()
                .eq(AlarmRuleNew.RES_GROUP_CODE_COLUMN, resGroupCode));

说明:

1. QueryWrapper<>()后建议换行
   不换行不友好写法范例

List<AlarmRuleNew> dbAlarmRules = mapperContext.getAlarmRuleNewMapper().selectList(new QueryWrapper<AlarmRuleNew>().eq(AlarmRuleNew.RES_GROUP_CODE_COLUMN, resGroupCode));

2. eq每个条件匹配后换行
   eq条件拼接一起的不友好写法范例

List<AlarmRuleNew> dbAlarmRules = mapperContext.getAlarmRuleNewMapper().selectList(new QueryWrapper<AlarmRuleNew>()
.eq(AlarmRuleNew.RES_GROUP_CODE_COLUMN, resGroupCode)..eq("yn", 0)
);

3. 最后结尾的)直接放到最后一个condition条件后，不要新起一行
   最后结尾)单独起一行的不友好写法

List<AlarmRuleNew> dbAlarmRules = mapperContext.getAlarmRuleNewMapper().selectList(new QueryWrapper<AlarmRuleNew>()
                .eq(AlarmRuleNew.RES_GROUP_CODE_COLUMN, resGroupCode)
);
