參考:eclipse建立springboot項目的三種方法 https://blog.csdn.net/mousede/article/details/81285693html
方法一:使用springboot插件java
1)、安裝STS插件web
2)、安裝插件導向窗口完成後,在eclipse右下角將會出現安裝插件的進度,等插件安裝完成後重啓eclipse生效spring
3)、新建spring boot項目apache
選擇須要的依賴:tomcat
4)、項目啓動, Finsh,OK done!springboot
(a)、運行maven build報錯No goals have been specified for this build.架構
運行maven報錯:eclipse
[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format : or :[:]:. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]
解決辦法,在pom.xml添加以下配置:maven
<build> <defaultGoal>compile</defaultGoal> </build>
(b)、關於Maven項目build時出現No compiler is provided in this environment的處理
[ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? [INFO] 1 error [INFO] ------------------------------------------------------------- [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 1.436 s [INFO] Finished at: 2017-06-28T11:16:07+08:00 [INFO] Final Memory: 10M/151M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project manage: Compilation failure [ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? [ERROR] -> [Help 1]
解決辦法:https://blog.csdn.net/lslk9898/article/details/73836745
方法二:使用springboot構建工具
一、使用構建工具自動生成項目基本架構, 自動建立web應用
1)、工具自動建立:http://start.spring.io/
2)、勾選須要的依賴:
其中,Group Id 是包名,Artifact Id 是項目名
二、在eclipse中引入maven項目
1)、點擊Generate Project下載項目壓縮包
解壓後,使用eclipse,Import -> Existing Maven Projects -> Next ->選擇解壓後的文件夾-> Finsh,OK done!
補充:
一、經常使用maven命令
clean:清除目標目錄中的生成結果。
generate-sources:開發環境與代碼分離,不多使用,執行這個命令能夠經過查看.classpath和.project兩個文件來查看變化。
install:在本地庫中安裝jar
test:運行項目中的單元測試
package:根據項目生成jar文件
tomcat*:run:啓動tomcat,前提是在項目的pom.xml文件中添加了tomcat插件
eclipse:eclipse:生成Eclipse項目文件,即.classpath和.project文件
compile:編譯源代碼
dependency:sources:下載項目依賴的jar包的源碼包
二、Eclipse maven配置:
參考:Eclipse上Maven環境配置使用 (全) https://www.cnblogs.com/tangshengwei/p/6341462.html
三、Eclipse maven 「update project」的意思:
update project自己是更新項目的意思。用在mave中是指pom.xml文件改動以後,須要執行Mavne/Update Project來更新外部依賴的jar包。
