在我的 Maven 项目中,我为 MongoDB java 驱动程序添加了一个依赖项。但是当我尝试运行该程序时,它会产生:
java.lang.NoClassDefFoundError: com/mongodb/MongoClient
com.therapy.Test.doGet(Test.java:27)
javax.servlet.http.HttpServlet.service(HttpServlet.java:624)
javax.servlet.http.HttpServlet.service(HttpServlet.java:731)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)
于是我在我的项目上右击,进入Run As -> Run Congfigurations... -> Classpath
,发现没有添加MongoDB jar:
将我的 MongoDB jar 添加到Classpath
选项卡会解决问题NoClassDefFoundError
吗?如果是这样,我该怎么做?
我的pom.xml
文件,如果需要:
