如何覆盖 Spring Boot 导入的版本号，而不在依赖项管理部分手动设置每个工件？

<properties>
    <spring.boot.version>1.5.7.RELEASE</spring.boot.version>
    <jackson.version>2.9.1</jackson.version>
</properties>
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>${spring.boot.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson</groupId>
            <artifactId>jackson-bom</artifactId>
            <version>${jackson.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

但是，当我跑步时

mvn dependency:tree "-Dincludes=com.fasterxml.jackson.*" -Dverbose

输出

[INFO] ------------------------------------------------------------------------
[INFO] Building dpt-domain-core 1.0.0
[INFO] ------------------------------------------------------------------------

[INFO]    \- (com.fasterxml.jackson.core:jackson-databind:jar:2.8.10:compile - omitted for duplicate)

那定义2.8.10的价值在哪里。jackson.versionorg.springframework.boot:spring-boot-dependencies:1.5.7.RELEASE:pom

但是，如果我明确添加

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>${jackson.version}</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${jackson.version}</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>${jackson.version}</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${jackson.version}</version>
</dependency>

到我的依赖管理部分，然后它正确解析为：

[INFO] ------------------------------------------------------------------------
[INFO] Building dpt-domain-core 1.0.0
[INFO] ------------------------------------------------------------------------
[INFO]
[INFO] --- maven-dependency-plugin:2.8:tree (default-cli) @ dpt-domain-core ---
[INFO] org.autodatacorp.dpt:dpt-domain-core:jar:1.0.0

[INFO] \- com.fasterxml.jackson.datatype:jackson-datatype-jsr310:jar:2.9.1:compile
[INFO] ------------------------------------------------------------------------

这很令人困惑，因为这似乎应该相当于执行 an importofcom.fasterxml.jackson:jackson-bom:2.9.1:pom应该相当于将该代码的内容手动粘贴到其中。

我什至试过

<dependency>                                                                                  
    <groupId>org.springframework.boot</groupId>                                               
    <artifactId>spring-boot-dependencies</artifactId>                                         
    <version>${spring.boot.version}</version>                                                 
    <exclusions>                                                                              
        <exclusion>                                                                           
            <groupId>com.fasterxml.jackson</groupId>                                          
            <artifactId>jackson-bom</artifactId>                                              
        </exclusion>                                                                          
    </exclusions>                                                                             
    <type>pom</type>                                                                          
    <scope>import</scope>                                                                     
</dependency>

但没有效果。

PS - 重要的是，我使用的 Maven 是：

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T11:41:47-05:00)
Java version: 9, vendor: Oracle Corporation

  1. 您可以重新订购 BOM 导入，这将起作用。将 Jackson BOM 放在 Spring Boot BOM 之前。快速示例https://github.com/Flaw101/gsonconverter/blob/feature/jackson_override/pom.xml
  2. 如果您使用 Spring Boot Parent POM，您只需要覆盖其属性jackson.version即可覆盖其他框架/库的版本

Spring Boot 也记录了这一点，

https://docs.spring.io/platform/docs/current/reference/html/getting-started-overriding-versions.html

几个额外的链接，

添加jackson-bom.version到 pom.xml 文件的属性部分应该会更新 jackson 依赖项。这将覆盖 Spring Boot Parent POM 中的 jackson 版本。

<properties>
    <jackson-bom.version>2.12.1</jackson-bom.version>
</properties>

使用jackson.version是行不通的。请参阅https://github.com/spring-projects/spring-boot/issues/17808
