java - 找不到类 javax.xml.bind.JAXBElement 的主构造函数或默认构造函数

问题描述

我一直在尝试将当前基于 Spring 的 Java 8 应用程序迁移到 Spring Boot 和 Java 11。以前我使用 Java 附带的 Jaxb，但在 Java 11 中我需要显式导入它，因为它不是 Java RT 的一部分。但是相同的代码给了我以下异常，我无法解决。

我在我的maven中导入的相关依赖如下：

    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-core</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>com.sun.activation</groupId>
        <artifactId>javax.activation</artifactId>
        <version>1.2.0</version>
    </dependency>
    <dependency>
        <groupId>javax.activation</groupId>
        <artifactId>javax.activation-api</artifactId>
        <version>1.2.0</version>
    </dependency>

我已经保证并排除了所有其他依赖项，这些依赖项带来了任何其他版本的 jaxb 库。这里的任何帮助都会有所帮助。

提前致谢！

在@Klaus 的推荐下，我将依赖项更改为 Jakarta EE Deps，依赖项树如下：

这是我得到这个异常的方法。它不进入方法，从签名中抛出异常。

@PostMapping(value = "/resource",
          consumes = MediaType.APPLICATION_XML_VALUE,
          produces = MediaType.APPLICATION_XML_VALUE)
  public JAXBElement<MyObject> send(final JAXBElement<MyObject> myList,
                                                     @RequestParam("Id") final String Id) { 

//It doesn't reach this point 
... }

再次感谢！
