Question

在创建简单的REST WS并在tomcat服务器上部署它时，我遇到了一个问题。我使用泽西原型创建了一个简单的休息WS：

mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-webapp \
            -DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
            -DgroupId=com.example -DartifactId=simple-service-webapp -Dpackage=com.example \
            -DarchetypeVersion=2.27

并且pom.xml看起来像：

<build>
    <finalName>simple-service-webapp</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.5.1</version>
            <inherited>true</inherited>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>
    </plugins>
</build>

    -->
    <dependency>

        <artifactId>jersey-container-servlet</artifactId>

    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-client</artifactId>

    <dependency>

        <artifactId>javax.ws.rs-api</artifactId>

    </dependency>
</dependencies>
<properties>
    <jersey.version>2.27</jersey.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

所以使用这个pom.xml和一个发送hello world的简单REST服务，我能够构建项目并获取war文件。

所以现在当我部署war文件并尝试访问Web服务时，它给出了一个错误：

Message Servlet.init() for servlet [Jersey Web Application] threw exception

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Exception

我尝试了之前在stackoverflow中为上述问题提出的解决方案，那就是使用HK2版本2.4。*或更高版本，当我这样做并创建war文件并进行部署时，访问WS会给出一个不同的错误，那就是：

Message Servlet.init() for servlet [Jersey Web Application] threw exception

如果有人能够为这个问题提供一些启示，将不胜感激。我正在使用JDK1.8编译我的项目，并将其部署在tomcat 9.0.6上。

提前致谢。

Answer 1

我在使用 Jersey 2.33 和 Tomcat 9 时遇到了类似的问题

我发现这个答案为我解决了https://stackoverflow.com/a/45687558/7105142

看起来你的 pom 中缺少 hk2-api

REST WS失败，出现java.lang.NoClassDefFoundError：org / glassfish / hk2 / api / ServiceLocatorFactory $ CreatePolicy错误
