spring-boot - JDK11 + Spring 启动 = JAXBException : Implementation of JAXB-API has not been found on module path or classpath

Question

我有一个基于 official guide 的简单 spring 项目消费网络服务。此示例似乎针对 JDK 8，但我想使用最新的 LTS，JDK 11。

我已经改编了 pom.xml文件并添加了一些似乎已从 JDK 中删除的依赖项，即:

        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-core</artifactId>
            <version>2.3.0.1</version>
        </dependency>

        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-runtime</artifactId>
            <version>2.3.2</version>
        </dependency>

        <dependency>
            <groupId>com.sun.xml.ws</groupId>
            <artifactId>rt</artifactId>
            <version>2.3.1</version>
        </dependency>

        <dependency>
            <groupId>com.sun.activation</groupId>
            <artifactId>javax.activation</artifactId>
            <version>1.2.0</version>
        </dependency>

但是，我似乎无法启动应用程序，总是收到此错误:

➜  spring-test git:(master) mvn spring-boot:run

尽管至少有两个问题( this 和 this )与此主题相关，但我已经尝试了在这些帖子中可以找到的所有版本组合，但仍然出现相同的错误。

我使用的特定 JDK+maven 版本是:

Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T16:06:16+01:00)
Maven home: /usr/local/Cellar/maven/3.6.2/libexec
Java version: 11.0.4, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk-11.0.4.jdk/Contents/Home
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.14.6", arch: "x86_64", family: "mac"

看看this answer并检查它是否可以帮助您。我们有几个项目使用 Java 11 和 Spring WS，一切正常。还要确保您的 pom.xml目标是 Java 11:

<properties>
    <java.version>11</java.version>
    <spring-cloud.version>Greenwich.SR2</spring-cloud.version>
</properties>

关于缺少的类，我们必须添加以下依赖项，仅此而已:

<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.2</version>
</dependency>
