Springboot 2.6集成redis maven報(bào)錯(cuò)

當(dāng)加這個(gè)配置后，POM.xml的第一行總是報(bào)錯(cuò)：

Description    Resource    Path    Location    Type
io.lettuce:lettuce-core:jar:6.1.8.RELEASE failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced.

看了意思是獲取不到最新包，因?yàn)閙aven之前已經(jīng)下載過(guò)，需要?jiǎng)h除m2庫(kù)里的最新玩意，

找到自己倉(cāng)庫(kù)，我的是C:\users\ckw\.m2\repository>,

在這個(gè)目錄下，打開(kāi)cmd，執(zhí)行：

for /r %i in (*.lastUpdated) do del %i

執(zhí)行這個(gè)批處理，

刪完后，按下面圖，update一把就好了

SpringBoot集成Redis連接不上

問(wèn)題描述

初學(xué)SpringBoot

當(dāng)進(jìn)行SpringBoot集成Redis時(shí)。測(cè)試向redis中添加String類(lèi)型的數(shù)據(jù)，key=name , value = zlw。

但出現(xiàn)了一下錯(cuò)誤：（Whitelabel Error Page）

看控制臺(tái)輸出發(fā)現(xiàn)，大致應(yīng)該是redis沒(méi)有連接成功。

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis; nested exception is io.lettuce.core.RedisConnectionException: Unable to connect to 192.168.86.129/<unresolved>:6379] with root cause

上網(wǎng)搜索了好多這個(gè)問(wèn)題的錯(cuò)誤，但好像都沒(méi)有解決，不是自己的錯(cuò)誤，但后來(lái)回想到，學(xué)習(xí)linux的時(shí)候，想要連接成功必須要關(guān)閉linux的防火墻才行。。。

試一試

可以看到防火墻已經(jīng)關(guān)閉了，

哇~有新發(fā)現(xiàn)了，，雖然頁(yè)面還是沒(méi)有變化，但控制臺(tái)的信息發(fā)生了變化。

提示：

WRONGPASS invalid username-password pair or user is disabled.

這應(yīng)該是我的redis密碼有問(wèn)題。。

原來(lái)是我的密碼加上了引號(hào)

記住：密碼要去掉引號(hào)?。?！

去掉雙引號(hào)之后再次訪問(wèn)，成功??！

總結(jié)

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
