json - 如何将 Jersey 与更新版本的 jackson 一起使用

Question

我正在使用带有 jersey-media-json-jackson 的 Jersey (2.23.1) .但这与 jackson 2.5.4 有关。但我需要使用 Jackson 2.6.0(或更新版本)。

我怎样才能做到这一点？

我试图在我的 pom.xml 中设置它:

    <dependency>
        <groupId>com.fasterxml.jackson.module</groupId>
        <artifactId>jackson-module-jsonSchema</artifactId>
        <version>2.6.0</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.6.0</version>
    </dependency>

    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-xml-provider</artifactId>
        <version>2.6.0</version>
    </dependency>

然后使用 jackson 2.6.0。 (我也尝试过更新的版本。)

但我的休息应用程序抛出各种NoSuchMethodError或 ClassNotFoundExceptions ， 像:

org.glassfish.jersey.server.ContainerException: java.lang.NoSuchMethodError: com.fasterxml.jackson.jaxrs.cfg.EndpointConfigBase.<init>(Lcom/fasterxml/jackson/databind/cfg/MapperConfig;)

有没有办法将 Jersey 2.23.1 与 Jackson 2.6.0 或更高版本一起使用？蒂亚!

这是我为 Jersey 启用 jackson 的方法:

    register(JacksonFeature.class);
    register(JacksonXMLProvider.class);

当你想覆盖一个版本时，你需要查看 pom.xml的模块。您在链接中看到明确声明了三个 Jackson 依赖项

<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-base</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
</dependency>

当您想使用新版本时，您有几个选择。您可以在 pom.xml 文件中使用您想要的版本显式声明所有它们，或者您可以排除所有依赖项，只显式声明主要的依赖项。

对于显式声明的选项，您可以只使用以上三个选项，指定您想要的版本。显式声明优先于传递依赖。因此，明确声明的将始终是拉入的，而不是泽西拉入的。

对于排除选项，您可以将它们从 jersey-media-json-jackson 中排除。 ，然后添加主要的拉动其他所有内容。在这种情况下 jackson-jaxrs-json-provider把另外两个拉进去，所以你真的只需要声明一个

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
    <version>2.23.1</version>
    <exclusions>
        <exclusion>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
        </exclusion>
        <exclusion>
            <groupId>com.fasterxml.jackson.jaxrs</groupId>
            <artifactId>jackson-jaxrs-base</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.jaxrs</groupId>
    <artifactId>jackson-jaxrs-json-provider</artifactId>
    <version>2.7.0</version>
</dependency>

这些方法中的任何一种都应该有效。

当您在更改版本时未声明所有依赖项时会发生什么情况，即可以传递旧版本的 jar，并且较新的版本之一尝试使用该旧版本 jar 中的某些类，而您最终会得到这些的错误。
