我正在向我的 Spring Web 应用程序添加一个过滤器。我正在使用 jdk 进行开发，所以我必须包含一个 servlet-api jar 来编译我的项目。我的理解是servlet api及其实现应该由jetty（我正在开发的容器）和tomcat（prod服务器）提供。当我将以下代码段添加到我的 pom.xml 时，我的项目编译成功。我的环境设置如下：

Java 1.6 jdk 码头 8.1.4.v20120524 Spring 3.2.0.Release

<dependency>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>servlet-api-2.5</artifactId>
    <version>6.1.14</version>
</dependency>

但是，当我在本地运行我的应用程序时，服务器在启动时会引发以下异常：

首先关于 servlet-api，我认为您的项目不需要依赖于 jetty，最好将您的依赖关系放在 api 本身上，并将其范围设置为已经提到的所提供的范围。

例如这样的事情：

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.0</version>
        <scope>provided</scope>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>

其次，关于您遇到的错误，您似乎缺少一些依赖项，您是否添加了 jersey multipart ？

<dependency>
    <groupId>com.sun.jersey.contribs</groupId>
    <artifactId>jersey-multipart</artifactId>
    <version>$your_version_of_jersey</version>
</dependency>
