環境：java1.8,ideajava
聚合工程優點：web
1.統一maven操做。能夠在一個maven工程管理多個子工程（每一個子工程可單獨打包，重啓，調試。也可經過聚合工程一塊兒管理）。redis
2.統一管理依賴版本。能夠藉助父工程（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。spring
3.統一引入公共依賴，而不須要每一個子項目都去重複引入。apache
4.防止pom.xml過長。json
指望達到的效果：瀏覽器
1.新建maven聚合父工程project-aggregation
file-new-project-maven服務器
快速建立一個maven工程，刪除無關文件，只保留pom.xmlmybatis
pom.xml文件內容以下app
<?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"> <!-- 基本信息 --> <description>SpringBoot 多模塊構建示例</description> <modelVersion>4.0.0</modelVersion> <name>project-aggregation</name> <packaging>pom</packaging> <!-- 項目說明：這裏做爲聚合工程的父工程 --> <groupId>com.pu</groupId> <artifactId>project-aggregation</artifactId> <version>1.0-SNAPSHOT</version> <!-- 繼承說明：這裏繼承SpringBoot提供的父工程 --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.5.RELEASE</version> <relativePath/> </parent> <!-- 模塊說明：這裏聲明多個子模塊 --> <modules> <module>helloworld</module> <module>mybatistest</module> </modules> <!-- 在properties中統一控制依賴包的版本，更清晰--> <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> <!--在此處統一加，子項目pom就能夠不用引入了--> <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> <!-- lombok --> <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用於管理依賴版本號--> <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> <!--feign --> <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>${poi.version}</version> </dependency> <!-- lombok --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>${lombok.version}</version> </dependency> </dependencies> </dependencyManagement> <!--該插件做用是打一個可運行的包，必需要寫在須要打包的項目裏。這裏的父模塊不須要打包運行，因此刪掉該插件。--> <!--<build>--> <!--<plugins>--> <!--<plugin>--> <!--<groupId>org.springframework.boot</groupId>--> <!--<artifactId>spring-boot-maven-plugin</artifactId>--> <!--</plugin>--> <!--</plugins>--> <!--</build>--> </project>
2.建子模塊module項目helloworld和mybatistest
父工程右鍵--》new-->module
finish,
helloworld的pom.xml
<?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> <!-- 基本信息 --> <groupId>com.pu</groupId> <artifactId>helloworld</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>helloworld</name> <description>Demo project for Spring Boot</description> <!-- 繼承本項目的父工程 --> <parent> <groupId>com.pu</groupId> <artifactId>project-aggregation</artifactId> <version>1.0-SNAPSHOT</version> <relativePath>../pom.xml</relativePath><!-- lookup parent from repository --> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
同理建另外一個module mybatistest,它的pom.xml
<?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.example</groupId> <artifactId>mybatistest</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>mybatistest</name> <description>Demo project for Spring Boot</description> <!-- 繼承本項目的父工程 --> <parent> <groupId>com.pu</groupId> <artifactId>project-aggregation</artifactId> <version>1.0-SNAPSHOT</version> <relativePath>../pom.xml</relativePath> <!-- lookup parent from repository --> </parent> <properties> <java.version>1.8</java.version> </properties> <dependencies> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
至此，聚合工程建立完畢,目錄結構以下：
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; @RestController public class helloController { @RequestMapping(value="/hello") //required=false 表示url中能夠不傳入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.啓動測試
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仍是helloworld的pom.xml,並無添加父pom內容，由於上面打包時已經把所須要的jar包打進去了
6.服務器發佈
