導(dǎo)入maven項(xiàng)目各個(gè)注解均報(bào)錯(cuò)

所遇問(wèn)題

導(dǎo)入maven項(xiàng)目各個(gè)注解均報(bào)錯(cuò)了

思考1：

這個(gè)項(xiàng)目使用了springboot;spring是個(gè)”大容器”，所有對(duì)象的創(chuàng)建和管理都交給了它，(SpringBoot是一個(gè)框架，一種全新的編程規(guī)范，他的產(chǎn)生簡(jiǎn)化了框架的使用，所謂簡(jiǎn)化是指簡(jiǎn)化了Spring眾多框架中所需的大量且繁瑣的配置文件，所以SpringBoot是一個(gè)服務(wù)于框架的框架，服務(wù)范圍是簡(jiǎn)化配置文件。

最明顯的特點(diǎn)是，讓文件配置變的相當(dāng)簡(jiǎn)單、讓?xiě)?yīng)用部署變的簡(jiǎn)單（SpringBoot內(nèi)置服務(wù)器，并裝備啟動(dòng)類(lèi)代碼），可以快速開(kāi)啟一個(gè)Web容器進(jìn)行開(kāi)發(fā)。)；先去查看springboot是否掃描到這些文件；

結(jié)果：查看配置文件XML以及各層的依賴(lài)，應(yīng)該沒(méi)出錯(cuò)。

思考2：

該導(dǎo)入的包是否成功導(dǎo)入？查看maven依賴(lài)樹(shù)（mvndependency），并檢查依賴(lài)版本等是否有用；結(jié)果：應(yīng)該沒(méi)錯(cuò)，依賴(lài)樹(shù)上顯示了加入的jar包。

思考3：

有事問(wèn)度娘；百度上的方法各異；我并沒(méi)有成功，也許是我操作或者對(duì)它們的理解出了問(wèn)題吧；決定問(wèn)大佬，我問(wèn)了大佬，大佬從事安卓開(kāi)發(fā)多年，所以幫我叫來(lái)另一個(gè)大佬；在另一個(gè)大佬的指點(diǎn)下，

解決方案

我先是去了本地倉(cāng)庫(kù)setting.xml下的鏡像改為aliyun的鏡像；（下圖是查找你當(dāng)前maven項(xiàng)目的本地倉(cāng)庫(kù)已經(jīng)配置文件setting.xml的方法）

我這個(gè)是默認(rèn)生成的，如果沒(méi)有配置文件setting.xml;就自己新建一個(gè)；新建方法很多這里就不介紹了；附上我的setting.xml
