java - ClassNotFoundException:com.sun.jersey.core.util.FeaturesAndProperties

我正在创建一个简单的REST应用程序，但是我得到了ClassNotFoundException类的com.sun.jersey.core.util.FeaturesAndProperties，它是jersey-core的一部分。我在这里添加的球衣依赖项中似乎有冲突，但我无法解决。

Pom.xml

编辑:按照维护相同版本的JAX-RS和Jersey的建议，我如下更改了依赖项，并且一切正常!

<dependencies>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-servlet</artifactId>
        <version>2.23.2</version>
    </dependency>
    <!-- Required only when you are using JAX-RS Client -->
    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-client</artifactId>
        <version>2.23.2</version>
    </dependency>
    <dependency>
        <groupId>javax.ws.rs</groupId>
        <artifactId>javax.ws.rs-api</artifactId>
        <version>2.0</version>
    </dependency>
</dependencies>

另外，更改了web.xml以反映新的jersey-servlet类。

<servlet>
    <servlet-name>jersey-serlvet</servlet-name>
    <servlet-class>
                 org.glassfish.jersey.servlet.ServletContainer
    </servlet-class>
    <init-param>
         <param-name>jersey.config.server.provider.packages</param-name>
         <param-value>com.example.rest</param-value>
    </init-param>
    <init-param>
    <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
    <param-value>true</param-value>
</init-param>

    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>jersey-serlvet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

最佳答案

您不能混合使用JAX-RS / Jersey版本

泽西版本1是JAX-RS 1的参考实现。泽西版本1使用com.sun.jersey组/软件包前缀。
泽西版2是JAX-RS 2的参考实现。泽西版2使用org.glassfish.jersey组/程序包前缀

如果可能，请使用JAX-RS / Jersey版本2。
