spring boot创建多模块聚合工程

發布時間：2025/4/16 编程问答 30 豆豆

生活随笔收集整理的這篇文章主要介紹了 spring boot创建多模块聚合工程小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

?環境：java1.8,idea

? ?聚合工程優勢：

1.統一maven操作?？梢栽谝粋€maven工程管理多個子工程（每個子工程可單獨打包，重啟，調試。也可通過聚合工程一起管理）。

2.統一管理依賴版本?？梢越柚腹こ?#xff08;dependencyManagement）來管理依賴包的版本，子工程就直接引用包而不用添加版本信息。

3.統一引入公共依賴，而不需要每個子項目都去重復引入。

4.防止pom.xml過長。

期望達到的效果：

1.新建maven聚合父工程project-aggregation

file-new-project-maven

快速創建一個maven工程，刪除無關文件，只保留pom.xml

pom.xml文件內容如下

<?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"><description>SpringBoot 多模塊構建示例</description><modelVersion>4.0.0</modelVersion><name>project-aggregation</name><packaging>pom</packaging><groupId>com.pu</groupId><artifactId>project-aggregation</artifactId><version>1.0-SNAPSHOT</version><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.5.RELEASE</version><relativePath/></parent><modules><module>helloworld</module><module>mybatistest</module></modules><properties><java.version>1.8</java.version><fastjson.version>1.2.32</fastjson.version><spring-cloud.version>Greenwich.SR1</spring-cloud.version><feign.version>2.1.1.RELEASE</feign.version><eureka-client.version>2.1.1.RELEASE</eureka-client.version><zkclient.version>0.10</zkclient.version><poi.version>3.13</poi.version><lombok.version>1.18.6</lombok.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId><version>${eureka-client.version}</version></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId><version>${feign.version}</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>${fastjson.version}</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>${poi.version}</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId><version>${poi.version}</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>${poi.version}</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>${lombok.version}</version></dependency></dependencies></dependencyManagement></project>

2.建子模塊module項目helloworld和mybatistest

父工程右鍵--》new-->module

?finish,

helloworld的pom.xml

同理建另一個module mybatistest,它的pom.xml

至此，聚合工程創建完畢,目錄結構如下：

3.編寫測試類

helloController.java

package com.pu.helloworld;import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController;/*** @Title:* @Auther: pujiahong* @Date: 2019/6/18 19:06* @Version: 1.0* @Description:*/ @RestController public class helloController {@RequestMapping(value="/hello")//required=false 表示url中可以不傳入id參數，此時就使用默認參數public String say(@RequestParam(value="id",required=false,defaultValue = "hello world") String input){return "your input :"+input;} }

4.啟動測試

url測試

idea菜單：Tools-->HTTP Client-->Test RESTful Web Service

單擊左上角運行

?5.打包helloworld

helloworld工程目錄?

依次點clean-->compile-->package

結果

壓縮軟件打開

相關jar包已經打進去了

配置文件

配置pom還是helloworld的pom.xml,并沒有添加父pom內容，因為上面打包時已經把所需要的jar包打進去了

6.服務器發布

[testapp@localhost ~/javaProject/service-helloworld]$ pwd /home/ap/testapp/javaProject/service-helloworld [testapp@localhost ~/javaProject/service-helloworld]$ ll 總用量 52336 -rw-rw-r-- 1 testapp testapp 524 6月 19 15:49 application.yml -rw-rw-r-- 1 testapp testapp 53573143 6月 19 15:48 helloworld-0.0.1-SNAPSHOT.jar drwxrwxr-x 2 testapp testapp 21 6月 19 15:55 log -rw-rw-r-- 1 testapp testapp 3209 6月 19 15:49 logback-boot.xml -rw-rw-r-- 1 testapp testapp 249 6月 19 15:54 start.sh -rw-rw-r-- 1 testapp testapp 92 6月 19 15:51 stop.sh [testapp@localhost ~/javaProject/service-helloworld]$ cat application.yml spring:application:name: service-helloword server:port: 8704 eureka:client:serviceUrl:#指向注冊中心defaultZone: http://192.168.111.133:8888/eureka/ instance:# 每間隔1s，向服務端發送一次心跳，證明自己依然”存活“lease-renewal-interval-in-seconds: 1# 告訴服務端，如果我2s之內沒有給你發心跳，就代表我“死”了，將我踢出掉。lease-expiration-duration-in-seconds: 2 logging:config: classpath:logback-boot.xml[testapp@localhost ~/javaProject/service-helloworld]$ cat start.sh nohup java -jar /home/ap/testapp/javaProject/service-helloworld/helloworld-0.0.1-SNAPSHOT.jar --spring.config.location=/home/ap/testapp/javaProject/service-helloworld/application.yml --spring.application.index=1 --server.port=8704 >/dev/null 2>&1 & [testapp@localhost ~/javaProject/service-helloworld]$ sh start.sh [testapp@localhost ~/javaProject/service-helloworld]$ cd log [testapp@localhost ~/javaProject/service-helloworld/log]$ cat sys.log 2019-06-19 15:55:17,106 INFO (SpringApplication.java:675)- No active profile set, falling back to default profiles: default 2019-06-19 15:55:38,897 INFO (StartupInfoLogger.java:59)- Started HelloworldApplication in 44.58 seconds (JVM running for 60.889) 2019-06-19 15:57:14,643 DEBUG (helloController.java:32)- your input :hello world [testapp@localhost ~/javaProject/service-helloworld/log]$
