spring - 不能用spring和tomcat运行昆德拉

标签 spring tomcat spring-mvc kundera

我正在尝试结合 Spring 和 Tomcat 7 启动并运行 Kundera，但在将 Kundera 依赖项添加到我的 pom 文件后出现以下错误。

当我忽略 Kundera 依赖项时，一切正常。这是什么原因造成的？

最佳答案

已修复!这为我解决了问题:

Make Tomcat Ignore Servlet in WEB-INF/LIB

我将 Kundera 依赖更改为:

<dependency>
        <groupId>com.impetus.kundera.client</groupId>
        <artifactId>kundera-cassandra</artifactId>
        <exclusions>
             <exclusion>
                <groupId>javax.servlet</groupId>
                <artifactId>servlet-api</artifactId>
             </exclusion>
             <exclusion>
                <artifactId>jetty-util</artifactId>
                <groupId>org.mortbay.jetty</groupId>
             </exclusion>
             <exclusion>
                <artifactId>jetty</artifactId>
                <groupId>org.mortbay.jetty</groupId>
             </exclusion>
        </exclusions>
        <version>2.11</version>
    </dependency>
