io.spring.platform繼承方式和import方式更改依賴版本號的問題

使用io.spring.platform時,它會管理各種通過集成測試的依賴版本號。spring

但有的時候,咱們想使用指定的版本號,這個時候就須要去覆蓋io.spring.platform的版本號。apache

前面的文章總結過,使用io.spring.platform有兩種方式,一種是繼承,一種是導入。springboot

1、先來看繼承的方式:

io.spring.platform使用Brussels-SR7版本框架

<parent>
  <groupId>io.spring.platform</groupId>
  <artifactId>platform-bom</artifactId>
  <version>Brussels-SR7</version>
</parent>

咱們想使用阿里的easyexcel框架,2.0.5版本maven

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>easyexcel</artifactId>
  <version>2.0.5</version>
</dependency>

這個時候就出現了依賴問題,easyexcel 2.0.5版本會依賴poi 3.17版本,而io.spring.platform管理的依賴倒是3.15版本。spring-boot

因爲依賴都是io.spring.platform管理的,因此打包時會強制使用poi 3.15版本,這會致使代碼執行時找不到對應的新版本class,執行失敗。測試

 

 

 在繼承方式使用io.spring.platform時,解決方法也比較簡單,覆蓋io.spring.platform對poi的版本號管理便可ui

<properties>
  <poi.version>3.17</poi.version>
</properties>

這個時候在來看依賴關係,發現poi的版本引入變成了3.17url

 

 

 這樣就解決了問題。spa

附上完整pom.xml

<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</groupId>
  <artifactId>springboot-dependency7</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>springboot-dependency7</name>
  <url>http://maven.apache.org</url>
  
  <parent>
    <groupId>io.spring.platform</groupId>
    <artifactId>platform-bom</artifactId>
    <version>Brussels-SR7</version>
  </parent>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <poi.version>3.17</poi.version>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>easyexcel</artifactId>
      <version>2.0.5</version>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <configuration>
          <mainClass>com.springboot_dependency7.main.Applicaiton</mainClass>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

 

2、再來看import的方式

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>io.spring.platform</groupId>
      <artifactId>platform-bom</artifactId>
      <version>Brussels-SR7</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

一樣引入easyexcel 2.0.5依賴

<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>easyexcel</artifactId>
  <version>2.0.5</version>
</dependency>

這個時候poi的版本被強制使用3.15

 

 

 要覆蓋io.spring.platform的版本號須要在pom.xml裏dependencyManagement節點io.spring.platform引入的前面加上poi的引入

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi</artifactId>
      <version>3.17</version>
    </dependency>
    <dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi-ooxml</artifactId>
      <version>3.17</version>
    </dependency>
    <dependency>
      <groupId>io.spring.platform</groupId>
      <artifactId>platform-bom</artifactId>
      <version>Brussels-SR7</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

再來看poi的依賴

 

 版本已經變成了3.17,解決問題。
