java - 使用 Xstream，需要说明

Question

考虑一个从 Bean 创建 JSON 的简单 Xsctream 示例:

Bean bean = new Bean();
bean.addNames("John", "Doe");
bean.addNames("Jane", "Doe");

XStream xstream = new XStream(new JettisonMappedXmlDriver());    
xstream.setMode(XStream.NO_REFERENCES);

System.out.println(xstream.toXML(bean));

结果

Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/jettison/mapped/Configuration
    at com.thoughtworks.xstream.io.json.JettisonMappedXmlDriver.<init>(JettisonMappedXmlDriver.java:55)
    at Main.main(Main.java:12)

请注意，库是按照应有的方式导入的

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.json.JettisonMappedXmlDriver;

并且包含适当的 jar
