如何使用Spring data mongoDB2.1.0.RELEASE与Spring boot2.0.5和Jhipster 5.3.3？

Question

我正在使用spring-boot 2.0.5.RELEASE与Jhipster 5.3.3，我的pom如下：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.github.jhipster</groupId>
            <artifactId>jhipster-dependencies</artifactId>
            <version>${jhipster-dependencies.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <!-- jhipster-needle-maven-add-dependency-management -->
    </dependencies>
</dependencyManagement>
...
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
...

现在，当我得知spring data发布了对MongoDB4事务管理的支持时，我想尝试一下，因为这听起来很酷！

基于Spring参考留档：https://docs.spring.io/spring-data/mongodb/docs/2.1.0.RELEASE/reference/html/#dependencies

使用spring data mongodb 2.1.0.RELEASE和spring boot就像添加releasetrain的BOM一样简单。我做了，我的pom变成了：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.github.jhipster</groupId>
            <artifactId>jhipster-dependencies</artifactId>
            <version>${jhipster-dependencies.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <!-- jhipster-needle-maven-add-dependency-management -->
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-releasetrain</artifactId>
            <version>Lovelace-RELEASE</version>
            <scope>import</scope>
            <type>pom</type>
        </dependency>
    </dependencies>

</dependencyManagement> 

但这并没有带来任何spring data MongoDB 2 . 1 . 0 jar，只有releasetrain lovelace的pom。Maven只下载releasetrain的pom，保持下载spring boot 2.0.5附带的spring数据mongodb 2.0.10。

我找到了这样做的方法，因为我使用Jhipster作为我的项目pom的父项目，我必须在Jhipster之前声明lovelace依赖管理，所以我的pom变成:

<dependencyManagement>
  <dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-releasetrain</artifactId>
        <version>Lovelace-RELEASE</version>
        <scope>import</scope>
        <type>pom</type>
    </dependency>
    <dependency>
        <groupId>io.github.jhipster</groupId>
        <artifactId>jhipster-dependencies</artifactId>
        <version>${jhipster-dependencies.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
</dependencies>

</dependencyManagement> 
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

然后Maven将下载lovelace的depenedncy management中指定的spring data mongodb版本。

我不得不阅读Spring引导参考指南来理解这一点。

也在pom.xml中添加spring-data-mongodb

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
    </dependency>
