初学springmvc求助, 404 not found

[freeman932]

为什么一个最简单的helloworld项目总是404 found错误，但运行目录下的jsp文件可以正常浏览。从网上下的其他人的简单项目也是404 found。难道是机器配置或Jar包的问题。

404 路径问题 看看路径哪里出问题了，再看看是否有缓存的影响等。

比如localhost/springmvc_hello/login.jsp就可以正常显示，而localhost/springmvc_hello/welcome.html就404 not found。清除了tomcat的缓存还是同样的错误。tomcat的servel.xml配置： <Server port="8005" shutdown="SHUTDOWN"> <GlobalNamingResources> <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" /> </GlobalNamingResources> <Service name="Catalina"> <Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" useBodyEncodingForURI="true" maxPostSize="0"/> <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" useBodyEncodingForURI="true" /> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> <Engine name="Catalina" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Context path="" docBase="F:\JavaProgram" debug="0" reloadable="false" crossContext="true"> </Context> </Host> </Engine> </Service> </Server>

可能是你的HTML文件没放在WebRoot下，而是不小心放到WEB-INF文件夹里了

[freeman932]

初步弄清了原因，是tomcat路径的问题

[qq_28042035]

楼主我也遇到了同样的问题，你是怎么解决的呀

[DobyJin]

使用动态路径应该会稳定些。
