1 京淘項(xiàng)目概述

解釋：動(dòng)吧旅游項(xiàng)目問題？

只有一個(gè)tomact服務(wù)器，將來有很多用戶請(qǐng)求不能應(yīng)對(duì)高并發(fā)，多批量的操作。 -------解決：配置tomact服務(wù)器集群。

現(xiàn)在 用戶訪問服務(wù)器：http:localhost:80但是還是訪問一臺(tái)服務(wù)器。將來項(xiàng)目上線后是通過域名進(jìn)行訪問某些具體的服務(wù)器 ------解決：使用代理服務(wù)器，一般在為了保證安全在前面有一道防火墻。流程：用戶統(tǒng)一訪問代理服務(wù)器，由代理服務(wù)器再把請(qǐng)求分發(fā)給不同的業(yè)務(wù)服務(wù)器。

tomact服務(wù)器的并發(fā)能力：150~240個(gè)/秒 一秒鐘提供150-240個(gè)請(qǐng)求。
如果不在經(jīng)過jvm調(diào)優(yōu) 200左右，如果通過jvm調(diào)優(yōu)可以實(shí)現(xiàn)單臺(tái)tomact服務(wù)器1000/秒 左右的的并發(fā)能力。-----調(diào)優(yōu)核心秘訣：擴(kuò)大tomact處理內(nèi)存的容量，但是并不是一味的調(diào)大就可以，調(diào)到某一程度最大在調(diào)可能會(huì)變?nèi)酢?/li>

數(shù)據(jù)將來儲(chǔ)存到數(shù)據(jù)庫，一般是mysql. 數(shù)據(jù)庫最大的連接數(shù)（即：可以允許并發(fā)的數(shù)量）：1000個(gè) . 連接數(shù)據(jù)庫的connection. 用戶如果有很多個(gè)請(qǐng)求，數(shù)據(jù)庫如何提高性能呢？ 配置 ，主數(shù)據(jù)庫 從數(shù)據(jù)庫。好處：數(shù)據(jù)庫一般都是電子設(shè)備，怕水和火。為了保證數(shù)據(jù)的安全性，數(shù)據(jù)一般存好幾份，分好幾個(gè)機(jī)房進(jìn)行儲(chǔ)存，一個(gè)地方出現(xiàn)問題也不影響其它地方。但這又出現(xiàn)了新問題，數(shù)據(jù)庫的鏈接地址：jdbc:///127.0.0.1:3306,這樣只能鏈接一臺(tái)數(shù)據(jù)庫，為了降低數(shù)據(jù)庫的負(fù)載壓力配置代理數(shù)據(jù)庫，用戶請(qǐng)求先連接代理數(shù)據(jù)庫服務(wù)器 ( 主庫和從庫的特點(diǎn)：主庫可以把數(shù)據(jù)源源不斷的同步到從庫，保證主庫的數(shù)據(jù)就是從庫的數(shù)據(jù))，把寫庫的操作放在主庫，讀數(shù)據(jù)就在從庫進(jìn)行讀取。------這樣就實(shí)現(xiàn)了讀和寫的分離，這種分別依次讀取多態(tài)數(shù)據(jù)庫的操作叫做負(fù)載均衡。

將來用戶可能有大批量讀的操作，每次訪問數(shù)據(jù)庫即使數(shù)據(jù)庫處理能力再高也會(huì)占用有限的資源。那么該如何讓用戶讀取的操作更加快速呢？ 使用緩存服務(wù)器，可能有多個(gè)緩存服務(wù)器叫做緩存的集群。這樣就可以解決大量的讀的操作。 那么寫的操作如何解決呢？ 隊(duì)列，如果緩存也經(jīng)受不住考驗(yàn)，再加上隊(duì)列來緩解數(shù)據(jù)庫的讀寫壓力。
總結(jié)：像這種即使出了問題也不影響程序運(yùn)行的方式叫做—高可用性，即使后臺(tái)服務(wù)器出了問題也不影響用戶的正常訪問

以上都是單體架構(gòu)的方式，缺點(diǎn)：其中一個(gè)部分壞掉，整個(gè)的業(yè)務(wù)邏輯也會(huì)壞掉。解決：微服務(wù)架構(gòu)。

2 導(dǎo)入京淘數(shù)據(jù)庫

2.1 安裝SqlYog可視化工具

注意：這個(gè)sql文件是通過sqlyog導(dǎo)出的數(shù)據(jù)庫文件，所以導(dǎo)入最好也用這個(gè)工具否則比如用navicat可能會(huì)出現(xiàn)數(shù)據(jù)丟失現(xiàn)象。

雙擊運(yùn)行:在課前資料的軟件中解壓到比如D盤中,進(jìn)入這個(gè)目錄把它發(fā)送到桌面,它是綠色免安裝版,只需解壓就可使用
第一次用的話可能會(huì)要進(jìn)行注冊(cè),只需要把sn.txt文件里面的破解的注冊(cè)碼信息粘貼過去就行。
軟件介紹:SQLyog 是一個(gè)快速而簡(jiǎn)潔的圖形化管理MYSQL數(shù)據(jù)庫的工具，它能夠在任何地點(diǎn)有效地管理你的數(shù)據(jù)庫，由業(yè)界著名的Webyog公司出品。使用SQLyog可以快速直觀地讓您從世界的任何角落通過網(wǎng)絡(luò)來維護(hù)遠(yuǎn)端的MySQL數(shù)據(jù)庫。

2.2 連接數(shù)據(jù)庫

步奏:雙擊運(yùn)行-----點(diǎn)擊左上角的按鈕(出現(xiàn)這個(gè)窗口) 如果沒有,點(diǎn)擊新建,然后再輸入對(duì)應(yīng)的信息如圖( 前提是數(shù)據(jù)庫正常安裝了)

2.3 導(dǎo)入JT數(shù)據(jù)庫

說明:導(dǎo)入課前資料中的jtdb.sql 數(shù)據(jù)庫文件.
步奏: 點(diǎn)擊左側(cè)空白處右鍵—從SQL轉(zhuǎn)儲(chǔ)文件導(dǎo)入數(shù)據(jù)庫----然后選擇數(shù)據(jù)庫的文件進(jìn)行導(dǎo)入—執(zhí)行—之后進(jìn)行刷新.

方式2: source 路徑/jtdb.sql;
步驟:找到數(shù)據(jù)庫文件的安裝根目錄位置—在窗口上cmd—可以直接進(jìn)入到DOS窗口中文件目錄的位置,直接在這個(gè)路徑下輸入dir可以看到當(dāng)前文件的目錄結(jié)構(gòu).再通過指令如下指令導(dǎo)入數(shù)據(jù)庫.
注意: 不能重復(fù)導(dǎo)入數(shù)據(jù)庫, 導(dǎo)入之后把數(shù)據(jù)庫刷新一下(左上角第6個(gè)圖標(biāo))

3 物理模型圖

使用場(chǎng)景分析,傳統(tǒng)數(shù)據(jù)庫使用Dos窗口的問題:
如果直接使用數(shù)據(jù)庫的視圖方式來檢查表與表之間的關(guān)系是非常困難的。如果需要做業(yè)務(wù)處理則看下圖中的表非常的不方便。
解決:使用物理模型圖設(shè)計(jì)表與表之間的聯(lián)系。
在項(xiàng)目創(chuàng)建初期，由高級(jí)程序員來規(guī)劃表關(guān)系。通過軟件可以將表與表之間的關(guān)聯(lián)通過視圖的形式直觀的給程序員展現(xiàn)，可以快熟的熟悉公式的業(yè)務(wù)流程。

最新版的navicat可以畫圖，公司一般常用的是PD軟件。

4 Power designer

4.1 PD介紹

PowerDesigner最初由Xiao-Yun Wang（王曉昀）在SDP Technologies公司開發(fā)完成。PowerDesigner是Sybase的企業(yè)建模和設(shè)計(jì)解決方案，采用模型驅(qū)動(dòng)方法，將業(yè)務(wù)與IT結(jié)合起來，可幫助部署有效的企業(yè)體系架構(gòu)，并為研發(fā)生命周期管理提供強(qiáng)大的分析與設(shè)計(jì)技術(shù)。PowerDesigner獨(dú)具匠心地將多種標(biāo)準(zhǔn)數(shù)據(jù)建模技術(shù)（UML、業(yè)務(wù)流程建模以及市場(chǎng)領(lǐng)先的數(shù)據(jù)建模）集成一體，并與 .NET、WorkSpace、PowerBuilder、Java?、Eclipse 等主流開發(fā)平臺(tái)集成起來，從而為傳統(tǒng)的軟件開發(fā)周期管理提供業(yè)務(wù)分析和規(guī)范的數(shù)據(jù)庫設(shè)計(jì)解決方案。此外，它支持60多種關(guān)系數(shù)據(jù)庫管理系統(tǒng)（RDBMS）/版本。PowerDesigner運(yùn)行在Microsoft Windows平臺(tái)上，并提供了Eclipse插件。
1).PD 可以根據(jù)不同的數(shù)據(jù)庫類型,動(dòng)態(tài)的生存Sql語句.
2).PD是一種可視化的軟件.可以將表與表之間的關(guān)聯(lián)關(guān)系,直觀的展現(xiàn).

4.2 PD安裝和使用 (安裝和破解)

1).執(zhí)行EXE文件(解壓后雙擊安裝,下一步即可,注意這個(gè)課前資料是windows版本的,電腦是其他系統(tǒng)的就不要在安裝了)
注意事項(xiàng): 1.安裝軟件的目錄,比如在D盤的目錄文件不要寫中文,空格.
2. 安裝時(shí)注意,可以選擇軟件的安裝路徑(沒有指定在c盤), 選擇中文格式(PRC)----同意協(xié)議.如下圖: 在之后什么都不需要選—下一步下一步即可 (有時(shí)候安裝有一個(gè).NET,點(diǎn)擊在線安裝,會(huì)聯(lián)網(wǎng)下載這個(gè)軟件)----Finish即可.

2).漢化軟件
如果打開pd需要先關(guān)上軟件(打開時(shí)不允許漢化)----找到pd的安裝目錄(1.如果安裝時(shí)指定了目錄就在指定位置找.2.如果沒有指定默認(rèn)是在c盤 總結(jié):找文件目錄, 在電腦windows窗口收索—PowerDesigner----右鍵) 然后打開課前資料的漢化版的補(bǔ)丁把所有的`dll文件復(fù)制到pd安裝的根目錄黏貼 (如圖)覆蓋原有的文件就行(注意不要把原來的所有文件刪除,他只是替換掉原有的重復(fù)文件)----在把pd的軟件發(fā)送到桌面就行. 卸載–在安裝目錄中的軟件右鍵–remove–下一步.

4.3 PD入門案例

步驟: 打開軟件—文件—建立新模型----Model type—物理模型圖 (如下圖所示)

4.4 創(chuàng)建物理模型圖

4.5 安裝時(shí)出現(xiàn)的問題分析:(查看博客錯(cuò)題集)

如:PD安裝時(shí)沒有出現(xiàn)數(shù)據(jù)庫類型:(沒有找到DBM的目錄)只需要點(diǎn)擊指定pd中的這個(gè)目錄.

4.6 PD入門

使用 pattle圖標(biāo)生成物理模型圖: 點(diǎn)擊Tabble鼠標(biāo)左鍵生成 刪除是: delete
使用物理模型圖生成表: 雙擊如圖: Name :名是給人看的 Code:是給數(shù)據(jù)庫看的(一般表名首字母大寫,不寫中文)----應(yīng)用,確定----添加表中的字段(columns)

查找 pattle工具: 工具(從右到左第三個(gè))—自定義工具欄—會(huì)彈出Toolbars窗口–勾選里面的Pattle即可.

同上 Name:是給人看的 code:數(shù)據(jù)庫看的 Data Type:數(shù)據(jù)庫類型 p:設(shè)置主鍵
Preview: 根據(jù)屬性,生成sql字段 將來可以直接復(fù)制黏貼到Dos窗口執(zhí)行即可

4.7 主鍵自增的設(shè)定

雙擊左側(cè)出現(xiàn)小箭頭—再雙擊出現(xiàn)這個(gè)彈窗—勾選右下角—identity設(shè)置主鍵自增–應(yīng)用,確定.
在sql語句的標(biāo)示: auto_increment

5 表結(jié)構(gòu)學(xué)習(xí)

5.1 一對(duì)一

業(yè)務(wù)場(chǎng)景:
User表~~~~~UserInfo表
從左向右看 : 1個(gè)用戶1個(gè)詳情
從右向左看: 1個(gè)詳情1個(gè)用戶
pk:主鍵
那么如何畫這種關(guān)系呢? 通過主外鍵關(guān)聯(lián).(使用第二行倒數(shù)第二個(gè)圖標(biāo) 由從表到主表 下面類似T的圖標(biāo)可以寫添加漢字,如下) 如果連接好會(huì)出現(xiàn)外鍵 fk,如果畫線不成功—雙擊這個(gè)線—出現(xiàn)彈窗-----joins—Child Table Column(點(diǎn)擊它的列表鍵)—用戶編號(hào)–應(yīng)用,確定.
注意不能改父級(jí)字段,只能改自己的字段(相當(dāng)于要求別人家的字段與自己表中的字段進(jìn)行主外鍵映射)

解釋下圖: 左邊是主表,右邊是從表, 主鍵是唯一的,外鍵不是唯一的 . 用戶表中的主鍵作為詳情表中的外鍵, 并且外鍵和主鍵作為標(biāo)示了同一個(gè)字段 都有主鍵所以都是雙向一對(duì)一.

5.2 一對(duì)多

業(yè)務(wù)場(chǎng)景:
用戶和部門 由從表到主表畫線(范圍大的是主表)
從左向右看: 1個(gè)用戶對(duì)應(yīng)1個(gè)部門 一對(duì)一 (主鍵對(duì)應(yīng)主鍵)
從右向左看: 1個(gè)部門有多個(gè)用戶 一對(duì)多 (一個(gè)主鍵對(duì)應(yīng)多個(gè)外鍵)

5.3 多對(duì)多

業(yè)務(wù)場(chǎng)景:
角色和權(quán)限
1個(gè)角色對(duì)應(yīng)多個(gè)權(quán)限 一對(duì)多
1個(gè)權(quán)限對(duì)應(yīng)多個(gè)角色 一對(duì)多
多對(duì)多用中間表 直接創(chuàng)建表不需要寫字段 有從表到主表畫線.
注意: 2個(gè)外鍵同時(shí)出現(xiàn)名字不能相同 fk1和fk2不能名字相同

5.4 京淘項(xiàng)目表結(jié)構(gòu)

6 SpringBoot加強(qiáng)

6.1 SpringBoot框架高級(jí)說明(pom文件的標(biāo)簽的說明)

6.1.1 parent標(biāo)簽的作用

<!--1.jar包種類繁多A.jar 1.0版本 B.jar 2.0版本 C.jar 3.0版本A.jar 2.0版本 B.jar 2.0版本 C.jar 3.0版本早期的jar包版本 可能出現(xiàn)jar包沖突的問題.所有采用parent標(biāo)簽的方式 統(tǒng)一定義了版本號(hào) 由官方自己進(jìn)行測(cè)試,將允許穩(wěn)定的版本統(tǒng)一的管理.在后期的依賴項(xiàng)中就不需要在添加版本了。--><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.2.RELEASE</version><relativePath /> <!-- lookup parent from repository --></parent>

解釋：relativePath標(biāo)簽

<relativePath /> <!-- lookup parent from repository -->設(shè)定一個(gè)空值將始終從倉(cāng)庫中獲取，不從本地路徑獲取，如<relativePath /> Maven parent.relativePath 默認(rèn)值為../pom.xml 查找順序：relativePath元素中的地址–本地倉(cāng)庫–遠(yuǎn)程倉(cāng)庫

思考：為什么parent標(biāo)簽定義好了版本號(hào)，為什么還要有dependencies呢？ parent相當(dāng)于一個(gè)購(gòu)物商城，只做了版本的定義。dependencies相當(dāng)于要什么只需要告訴它要什么。

6.1.2 關(guān)于maven 插件的說明

<!-- maven項(xiàng)目指定的插件配置,該插件主要負(fù)責(zé)maven項(xiàng)目相關(guān)操作:打包/test/clean/update等相關(guān)maven操作 注意事項(xiàng):但凡是maven項(xiàng)目則必須添加 插件.否則將來項(xiàng)目部署必然出錯(cuò) --><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>

6.1.3 關(guān)于Maven 屬性的配置

<!--當(dāng)前maven配置信息 --><properties><!--配置jdk版本版本 --><java.version>1.8</java.version><!--定義maven插件版本 --><maven-jar-plugin.version>3.1.1</maven-jar-plugin.version><!--定義跳過配置類打包 ，項(xiàng)目在發(fā)布后不需要測(cè)試類。但不能手動(dòng)刪，將來可能會(huì)用，所以用這個(gè)配置跳過測(cè)試類打包--><skipTests>true</skipTests></properties>

6.1.4 依賴與本地倉(cāng)庫的關(guān)系

1).

<!--maven的依賴 利用坐標(biāo)的形式管理jar包 本地倉(cāng)庫之間有什么關(guān)系呀? --><dependency><!--組ID, 公司域名倒寫. --><groupId>org.springframework.boot</groupId><!--具體項(xiàng)目名稱 --><artifactId>spring-boot-starter-web</artifactId><!--版本號(hào) 被parent標(biāo)簽提前定義 --><!-- <version>2</version> --></dependency>

2).本地倉(cāng)庫內(nèi)容

3).規(guī)則說明
如果以后下載jar包時(shí),遇到maven依賴異常.則首先查詢本地倉(cāng)庫中是否有該jar包的完整版本.如果發(fā)現(xiàn)jar包文件下載不完全,則需要?jiǎng)h除之后重新下載.

6.1.5 jar包與jar包之間的依賴傳遞性說明

問題:導(dǎo)入了web依賴，為什么會(huì)自動(dòng)導(dǎo)入其他依賴呢 如:tomact json等。
1.說明: maven具有jar包的依賴性
例如: A.jar---->B.jar ------> C.jar
只要導(dǎo)入A.jar 那么b/c都會(huì)自動(dòng)的完成依賴

2).檢查POM.xml文件
說明:由于maven加載jar包之后還會(huì)去加載該jar包文件的POM文件,如果該P(yáng)OM文件中依賴了其他的jar包(如下圖所示:打開的jar包中的pom文件),那么maven也會(huì)自動(dòng)的進(jìn)行加載.

7 京淘項(xiàng)目環(huán)境搭建

7.1 JDK環(huán)境說明

檢查jdk環(huán)境

7.2 JDK環(huán)境變量配置

在系統(tǒng)變量中配置:jdk根目錄和path路徑。

7.3 Maven配置

7.3.1 本地倉(cāng)庫位置

打開maven中的conf/setting.xml文件，并對(duì)其如下選項(xiàng)進(jìn)行配置。

1.配置maven本地庫(從maven遠(yuǎn)程服務(wù)器下載的資源存儲(chǔ)到的位置) 55行

<localRepository>${user.home}/.m5/repository</localRepository>

解釋：（use.home 表示在:c盤----當(dāng)前用戶User—Administrator 配置完后下面的目錄.m5會(huì)幫你自動(dòng)創(chuàng)建）
這里改用E盤,這2個(gè)目錄會(huì)自動(dòng)幫你創(chuàng)建

<localRepository>E:/jarbaocangku-idea/repository</localRepository>

7.3.2 檢查Maven私服鏡像位置

檢查Maven私服鏡像的地址 (maven安裝的目錄—conf目錄–setting.xml,160行左右,一般用阿里云的)

<mirror><id>aliyun</id><name>aliyun for maven</name><mirrorOf>*</mirrorOf><url>https://maven.aliyun.com/repository/public</url></mirror>

7.3.3 配置maven中JDK編譯和運(yùn)行版本

配置到profiles標(biāo)簽內(nèi)部,230行

<profile><id>jdk-1.8</id><activation><activeByDefault>true</activeByDefault><jdk>1.8</jdk></activation><properties><maven.compiler.source>1.8</maven.compiler.source><maven.compiler.target>1.8</maven.compiler.target><maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion></properties> </profile>

8 創(chuàng)建項(xiàng)目測(cè)試

8.1 IDEA創(chuàng)建SpringBoot(第一種)

步驟:選中工作空間(右鍵)----new—module(模塊)
module:模塊，工作空間里的一個(gè)個(gè)項(xiàng)目稱之為一個(gè)個(gè)的模塊。

添加web依賴

8.2 SpringBoot項(xiàng)目創(chuàng)建方式(第二種)

8.2.1 步驟

用普通Maven項(xiàng)目創(chuàng)建項(xiàng)目,相比用插件創(chuàng)建項(xiàng)目缺少：1.pom文件缺失依賴。2：缺少主啟動(dòng)類。3.因?yàn)樘砑恿藈eb依賴,所以缺少resources目錄下的static templates 配置文件目錄。因?yàn)槭蔷酆瞎こ逃貌坏竭@2個(gè)目錄static templates，所以不用創(chuàng)建。4.缺少配置文件。

8.2.2 編輯POM.xml文件

添加缺少的依賴坐標(biāo):
普通maven項(xiàng)目相比springboot項(xiàng)目的pom文件缺少4個(gè)標(biāo)簽:1.parent標(biāo)簽。2.maven屬性標(biāo)簽properties。3.第三方依賴標(biāo)簽dependencies。4.插件標(biāo)簽build。

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.jt</groupId><artifactId>springboot_demo2</artifactId><version>1.0-SNAPSHOT</version><!--1.統(tǒng)一定義父級(jí)項(xiàng)目--><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.4.5</version><relativePath/> <!-- lookup parent from repository --></parent><!--2.properties標(biāo)簽,當(dāng)前maven配置信息如:jdk版本,插件版本(可加可不加),跳過測(cè)試類打包等。--><properties><java.version>1.8</java.version><skipTests>true</skipTests></properties><!--3.引入第三方依賴--><dependencies><!--整合springmvc的--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!--整合test文本的--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><!--4.添加插件--><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

注意:添加完依賴后要進(jìn)行更新。

8.3 編輯主啟動(dòng)類

8.3.1 創(chuàng)建包

在java目錄上右鍵—new—package(起個(gè)名字如:com.ct)—點(diǎn)擊鍵盤上的Enter鍵。
注意在idea中包和類是分開創(chuàng)建的,沒有像sts那樣在創(chuàng)建類的同時(shí)可以創(chuàng)建包。

8.3.2 創(chuàng)建類(接口 枚舉 注解)

在包名上右鍵----new–java class

package com.ct;import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication//標(biāo)識(shí)我是一個(gè)SpringBoot的項(xiàng)目 public class SpringBootRun {public static void main(String[] args) {/*** main方法是java程序的唯一入口* @param args*/SpringApplication.run(SpringBootRun.class,args);} }

8.8.3 運(yùn)行

運(yùn)行:在主啟動(dòng)類的方法名字上右鍵…

8.8.4 編輯測(cè)試Controller

package com.jt.controller;import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController;@RestController public class HelloController {/*** 用戶通過/hello的路徑獲取 友好的提示信息.*/@RequestMapping("/hello")public String hello(){return "搭建環(huán)境真困難,為什么就我的不行呢? 我昨天干了什么呢!!!!!";} }

運(yùn)行

9 SpringBoot啟動(dòng)原理說明

9.1 需求說明

1.SpringBoot啟動(dòng)是如何流轉(zhuǎn)的.
2.什么叫做開箱即用,springBoot中如何實(shí)現(xiàn)開箱即用的.

9.2 "開箱即用"說明

@Target(ElementType.TYPE) 對(duì)哪個(gè)元素有效 對(duì)類有效
@Retention(RetentionPolicy.RUNTIME) 什么時(shí)候起作用 運(yùn)行期有效
@Documented 是否支持生成文檔
@Inherited 該注解是否可以被繼承.

9.3.2 SpringBootConfiguration說明

作用:標(biāo)識(shí)主啟動(dòng)類是一個(gè)大型的配置文件,啟動(dòng)時(shí)會(huì)加載所有的小的配置文件.

@Configuration: 表示該類是一個(gè)配置類.

@Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) @Documented @Configuration public @interface SpringBootConfiguration {.....}

9.3.3 excludeFilters 說明

說明: 在springboot容器啟動(dòng)時(shí),不需要加載某些過濾器.由于parent標(biāo)簽中定義了所有的關(guān)聯(lián)的jar包文件信息.則啟動(dòng)時(shí)有可能導(dǎo)致意外的發(fā)生,所有需要提前剔除.

@ComponentScan(excludeFilters = { @Filter(type = FilterType.CUSTOM, classes = TypeExcludeFilter.class),
@Filter(type = FilterType.CUSTOM, classes = AutoConfigurationExcludeFilter.class) })

9.3.4 @AutoConfigurationPackage

說明: 當(dāng)程序啟動(dòng)時(shí),會(huì)根據(jù)主啟動(dòng)類的包路徑,掃描其子孫包,所以springboot以后寫代碼時(shí)應(yīng)該在其子孫包下編輯.

9.3.5 AutoConfigurationImportSelector

說明:該配置中內(nèi)部集成了所有的SpringBoot中的選擇器.這些選擇器的主要的任務(wù)就是查看是否有自己選擇器所管理的啟動(dòng)項(xiàng)的配置. 如果發(fā)現(xiàn)該啟動(dòng)項(xiàng),那么選擇器就會(huì)執(zhí)行該啟動(dòng)項(xiàng),從而實(shí)現(xiàn)了開箱即用的操作.

1.創(chuàng)建yml文件:resources—new—file(application.yml)
2.配置日志級(jí)別,啟動(dòng)項(xiàng)目。

9.4 總結(jié):簡(jiǎn)述Spring Boot運(yùn)行流程

首先通過pom.xml文件進(jìn)行jar包文件的標(biāo)識(shí)，parent標(biāo)簽定義了當(dāng)前spring boot所包含以及所依賴的其它版本的依賴信息進(jìn)行定義。之后用戶依賴了那個(gè)jar包，后會(huì)根據(jù)Maven jar包自動(dòng)依賴的規(guī)則，進(jìn)行動(dòng)態(tài)的導(dǎo)入。然后通過主啟動(dòng)類進(jìn)行加載。

導(dǎo)入規(guī)則：導(dǎo)包之后，Maven找到j(luò)ar包文件在讀取當(dāng)前jar包的pom文件再次進(jìn)行jar包的依賴。

10.1 IDEA如何刪除項(xiàng)目

IDEA想要?jiǎng)h除項(xiàng)目需要先移除，移除之后沒有藍(lán)色圖標(biāo)變?yōu)槠胀ǖ奈募?#xff0c;不是java項(xiàng)目了。

之后再右鍵delete

10.2 IDEA導(dǎo)入項(xiàng)目

直接把項(xiàng)目粘貼到工作空間，但是這樣導(dǎo)入的不是Maven項(xiàng)目。
如何變?yōu)镸aven項(xiàng)目？ pom文件是Maven項(xiàng)目的標(biāo)識(shí)。
步驟:點(diǎn)擊pom文件右鍵-----Add as Maven Project–在右側(cè)就會(huì)標(biāo)識(shí)(profiles)這是一個(gè)Maven項(xiàng)目

只要Maven導(dǎo)入成功之后就不會(huì)出現(xiàn)Add as Maven Project這個(gè)提示。

10.3 項(xiàng)目發(fā)布問題

10.3.1 項(xiàng)目打包

說明:如果需要項(xiàng)目的發(fā)布則需要將項(xiàng)目打包處理.打完包之后,會(huì)在target目錄中動(dòng)態(tài)生成jar/war包. 以及本地倉(cāng)庫中也會(huì)有包?
擴(kuò)展: 本地倉(cāng)庫的包有啥作用? 作用:就是被其他項(xiàng)目依賴.因?yàn)轫?xiàng)目將來會(huì)有多個(gè)并且極其復(fù)雜.
clean: 的作用是刪除target目錄. (早期是刪除是 本地的target文件和本地倉(cāng)庫的一塊刪除,現(xiàn)在是只刪除target目錄,所以現(xiàn)在打包是先install,防止用的是本地倉(cāng)庫中以前的包) target:是存放編譯后的文件.

根據(jù)你xml文件配置(項(xiàng)目中的坐標(biāo))的路徑找到本地倉(cāng)庫中的jar包,如下
如果沒有指定在c盤 指定了就在指定位置找 詳情看第二階段筆記.

site:是生成jar包依賴報(bào)告 install:打包 (上圖標(biāo)錯(cuò)了)

10.3.2 項(xiàng)目發(fā)布

說明:將項(xiàng)目打包之后,發(fā)布到指定的文件中,之后利用命令啟動(dòng).
打包后在target目錄下生成項(xiàng)目的jar包,直接復(fù)制黏貼一個(gè)文件中(不要中文和空格)

直接在這個(gè)窗口cmd進(jìn)入文件目錄位置.

控制臺(tái)輸出:java -jar 打包的文件名

取消組合鍵: ctrl + c (點(diǎn)擊時(shí)鼠標(biāo)雙擊控制臺(tái),鎖定了別人用不了,訪問時(shí)會(huì)一直轉(zhuǎn)圈,在Dos窗口ctrl+c)
項(xiàng)目訪問:
