导入BOM POM时，如何覆盖Spring Boot的版本号

如何覆盖Spring Boot导入的版本号，而无需在"依赖关系管理"部分中手动设置每个工件？

<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，当我运行

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)

其中2.8.10是org.springframework.boot:spring-boot-dependencies:1.5.7.RELEASE:pom定义的jackson.version的值。

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>

到我的依赖项管理 e节，它可以正确解决到：

[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.core:jackson-annotations:jar:2.9.1:compile

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

令人困惑的是，因为这似乎应该等同于执行com.fasterxml.jackson:jackson-bom:2.9.1:pom的import应该是将该代码的内容粘贴到手动中的等效。

我什至尝试了

<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>

但无效。

ps-重要的是，我正在使用的maven是：

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

您可以重新订购BOM进口，这将起作用。将杰克逊·鲍（Jackson bom）放在春季靴子之前。快速示例https://github.com/flaw101/gsonconverter/blob/feature/jackson_override/pom.xml
如果您使用弹簧靴父母POM，则只需覆盖其属性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/referent/Reference/html/getting-started-overriding-versions.html

其他几个链接，

https://docs.spring.io/spring-boot/docs/current/referent/referent/referent/html/using-boot-build-systems.html#using-boot-boot-maven-parent-parent-parent-pom

https://docs.spring.io/spring-boot/docs/current/referent/referent/html/using-boot-build-systems.html#using-boot-boot-maven-without-a-parent-a-parent-a-parent

将 jackson-bom.version添加到pom.xml文件的属性部分，应更新杰克逊依赖关系。这将覆盖弹簧靴父母POM中的杰克逊版。

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

使用jackson.version无法正常工作。请参阅https://github.com/spring-projects/spring-boot/issues/17808
