一、咱們在開發過程當中,會常常須要啓動、中止微服務,並且有時候會比較頻繁,須要不停的操做啓停動做; 二、而咱們本章節主要講解下如何在開發環境中進行熱部署,這樣的話能夠在必定程度上專心敲代碼,兩耳不聞窗外事,一心只想敲代碼;

/**************************************************************************************** 1、簡單用戶微服務接口測試: 一、添加 spring-boot-devtools 熱部署依賴; 二、pom.xml 添加 <fork>true</fork> 屬性; 三、設置 idea 屬性:「File」 -> 「Settings」 -> 「Build,Execution,Deplyment」 -> 「Compiler」,選中打勾 「Build project automatically」 ; 四、設置 idea 屬性:組合鍵:「Shift+Ctrl+Alt+/」 ,選擇 「Registry」 ,選中打勾 「compiler.automake.allow.when.app.running」 ; 五、設置緩存配置 spring.thymeleaf.cache=false; 六、設置 chrome 屬性:F12或者「Ctrl+Shift+I」,打開開發者工具,「Network」 選項卡下 選中打勾 「Disable Cache(while DevTools is open)」 ; 七、啓動 springms-simple-provider-user-devtools 模塊服務,啓動1個端口; 八、在瀏覽器輸入地址 http://localhost:8305/simple 能夠看到信息成功的被打印出來; 九、改動 Controller 某個方法的返回值,或者新增方法,而後會看到控制檯自動重啓該應用,進行熱部署; 十、再在瀏覽器請求剛剛改動的連接,發現連接返回的內容確實動態改變過來了,這就是熱部署; ****************************************************************************************/
