本指南將幫助您了解Spring Boot Starter Parent如何幫助管理依賴項版本，所有Spring Boot項目通常使用spring-boot-starter-parent作為pom.xml中的父項：
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.0.RELEASE</version> </parent>
Parent Poms為多個子項目和模塊管理以下內容：
內部原理
首先 啟動器Spring Boot Starter Parent將spring-boot-dependencies定義為父pom。它從spring-boot-dependencies繼承了依賴關系管理。
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>1.4.0.RELEASE</version> <relativePath>../../spring-boot-dependencies</relativePath></parent>
默認的java版本是1.6。項目可以通過<java.version>1.8</java.version>在項目pom中指定屬性來覆蓋它。還有一些與編碼和源相關的其他設置，目標版本也在父pom中設置。
<java.version>1.6</java.version><resource.delimiter>@</resource.delimiter> <!-- delimiter that doesn't clash with Spring ${} placeholders --><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><maven.compiler.source>${java.version}</maven.compiler.source><maven.compiler.target>${java.version}</maven.compiler.target>Spring Boot Starter Parent指定了一系列插件的默認配置，包括maven-failsafe-plugin，maven-jar-plugin和maven-surefire-plugin。
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-failsafe-plugin</artifactId> <executions> <execution> <goals> <goal>integration-test</goal> <goal>verify</goal> </goals> </execution> </executions></plugin><plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <archive> <manifest> <mainClass>${start-class}</mainClass> <addDefaultImplementationEntries>true</addDefaultImplementationEntries> </manifest> </archive> </configuration></plugin><plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <includes> <include>**/*Tests.java</include> <include>**/*Test.java</include> </includes> <excludes> <exclude>**/Abstract*.java</exclude> </excludes> </configuration></plugin>Spring Boot Starter Parent從spring-boot-dependencies繼承了什么？
Spring Boot Dependencies定義了所有Spring Boot項目的默認依賴關系管理。如果我們想要使用特定依賴項的新版本，我們可以通過在項目pom中指定新屬性來覆蓋該版本。下面的摘錄顯示了由Spring Boot Dependencies父pom管理的一些重要依賴項。由于Spring Boot Starter Parent繼承自spring-boot-dependencies，因此它也共享所有這些特性。
<properties> <activemq.version>5.13.4</activemq.version> ... <ehcache.version>2.10.2.2.21</ehcache.version> <ehcache3.version>3.1.1</ehcache3.version> ... <h2.version>1.4.192</h2.version> <hamcrest.version>1.3</hamcrest.version> <hazelcast.version>3.6.4</hazelcast.version> <hibernate.version>5.0.9.Final</hibernate.version> <hibernate-validator.version>5.2.4.Final</hibernate-validator.version> <hikaricp.version>2.4.7</hikaricp.version> <hikaricp-java6.version>2.3.13</hikaricp-java6.version> <hornetq.version>2.4.7.Final</hornetq.version> <hsqldb.version>2.3.3</hsqldb.version> <htmlunit.version>2.21</htmlunit.version> <httpasyncclient.version>4.1.2</httpasyncclient.version> <httpclient.version>4.5.2</httpclient.version> <httpcore.version>4.4.5</httpcore.version> <infinispan.version>8.2.2.Final</infinispan.version> <jackson.version>2.8.1</jackson.version> .... <jersey.version>2.23.1</jersey.version> <jest.version>2.0.3</jest.version> <jetty.version>9.3.11.v20160721</jetty.version> <jetty-jsp.version>2.2.0.v201112011158</jetty-jsp.version> <spring-security.version>4.1.1.RELEASE</spring-security.version> <tomcat.version>8.5.4</tomcat.version> <undertow.version>1.3.23.Final</undertow.version> <velocity.version>1.7</velocity.version> <velocity-tools.version>2.0</velocity-tools.version> <webjars-hal-browser.version>9f96c74</webjars-hal-browser.version> <webjars-locator.version>0.32</webjars-locator.version> <wsdl4j.version>1.6.3</wsdl4j.version> <xml-apis.version>1.4.01</xml-apis.version></properties>
將Maven 3.2.1定義為所需的最低版本：
