hi going through first lessons spring 3.i created dynamic web app in eclipse following structure.
spring3mvc \src\my.spring.helloworldcontroller.java \webcontent | |-----web-inf\jsp\hello.jsp |-----index.jsp |-----web-inf\web.xml |-----web-inf\spring-servlet.xml |-----web-inf\lib\...*.jar files
i created spring-servlet.xml below
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/context http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <mvc:annotation-driven/> <context:component-scan base-package="my.spring" /> <bean id="jspviewresolver" class="org.springframework.web.servlet.view.internalresourceviewresolver" p:prefix="/web-inf/jsp/" p:suffix=".jsp"> <property name="contenttype" value="text/html; charset=utf-8" /> </bean> </beans>
and coded controller
package my.spring; import org.springframework.stereotype.controller; import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.servlet.modelandview; @controller public class helloworldcontroller { @requestmapping("/hello") public modelandview helloworld() { string message = "hello world, spring 3.0!"; return new modelandview("hello", "message", message); } }
index.jsp has link hello view
<html> <body> <a href="hello.html">say hello</a> </body> </html>
finally in hello.jsp have put
<html> <body> ${message} </body> </html>
my web.xml has
<display-name>spring3mvc</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>spring</servlet-name> <servlet-class> org.springframework.web.servlet.dispatcherservlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> </servlet-mapping>
when run app on tomcat6 server( thru eclipse),i can see index page @ http://localhost:8080/spring3mvc/ .it displays link hello page.when click on it(http://localhost:8080/spring3mvc/hello.html),i 404 error.
message /spring3mvc/hello.html description requested resource (/spring3mvc/hello.html) not available.
any idea how can solve this?
thanks
mark.
i belive problem not view resolver (it print other exceptions).
read error message carfully, tells problem is:
message /spring3mvc/hello.html description requested resource (/spring3mvc/hello.html) not available.
it hello .html (handler) can not found, not jsp. -- don't know exact problem it. -- tryed reproduce error, did not exact same error message.
added -- find problem
when start server prints mappings controller in log file. in case there must like
info : org.springframework.web.servlet.mvc.annotation.defaultannotationhandlermapping - mapped url path [/hallo] onto handler 'hallocontroller'
if don't have such statement, wrong context scan, or have forget enable annotation driven mvc @controller programming model. can enabled adding:
<!-- enables spring mvc @controller programming model --> <annotation-driven />
