java.lang.ClassNotFoundException：com.sun.jersey.spi.service.ComponentProvider

Question

我使用Spring并决定使用Jersey添加REST服务。 这是我的maven依赖

<!-- Jersey -->
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.18.1</version>
    </dependency>
    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-client</artifactId>
        <version>1.18.1</version>
    </dependency>
    <dependency>
         <groupId>com.sun.jersey</groupId>
         <artifactId>jersey-json</artifactId>
         <version>1.18.1</version>
    </dependency>
    <dependency>
         <groupId>com.sun.jersey</groupId>
         <artifactId>jersey-servlet</artifactId>
         <version>1.18.1</version>
    </dependency>
    <dependency>
         <groupId>com.sun.jersey</groupId>
         <artifactId>jersey-spring</artifactId>
         <version>1.0</version>
         <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-core</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-web</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-beans</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

这是我的web.xml配置

<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>namespace</param-name>
        <param-value>mvc</param-value>
    </init-param>
</servlet>

<servlet>
    <servlet-name>jersey-servlet</servlet-name>
    <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
    <init-param>
         <param-name>com.sun.jersey.config.property.packages</param-name>
         <param-value>com.c.library.web.ws</param-value>
    </init-param>
</servlet>

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

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>*.html</url-pattern>
    <url-pattern>*.ajax</url-pattern>
</servlet-mapping>

但是当我启动tomcat时，我遇到了错误

问题是什么？我的服务看起来像这样

package com.c.library.web.ws;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

import org.springframework.stereotype.Component;

@Component
@Path("/helloworld")
public class JerseyRestService {

    @GET
    @Produces("text/plain")
    public String getHello() {
        return "Hello world!";
    }

}

我遇到了同样的问题。但我错过了jersey-servlet依赖。 POM中的以下依赖项解决了这个问题：

<dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.18.1</version>
</dependency>
<dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-servlet</artifactId>
        <version>1.18.1</version>
</dependency>
