java - Spring REST web service appContext failed -

i'm trying create rest web service using spring.

i have 1 controller, 1 appcontext.

controller:

@controller public class restcontroller {  @requestmapping(method=requestmethod.post, value="service/{url}......<params>)  //some method here  //some logic here  } 

and app context:

<?xml version="1.0" encoding="utf-8"?> <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"         xsi:schemalocation="                 http://www.springframework.org/schema/beans                 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd                 http://www.springframework.org/schema/context                  http://www.springframework.org/schema/context/spring-context-3.0.xsd">          <context:component-scan base-package="spring.rest.controller" />          <bean class="org.springframework.web.servlet.mvc.annotation.defaultannotationhandlermapping" />         <bean class="org.springframework.web.servlet.mvc.annotation.annotationmethodhandleradapter" />  </beans>

libs used - spring beans, core, context, web, webmvc, security-core, oxm. p.s. never used spring before, have no idea wrong.

any suggestions?

you're missing spring expression jar file.

since have have spring core jar file, should have expression jar file if using project build manager such maven spring-expression dependency of spring-core. in case, chances there problem deploying expression jar file (either doesn't exist in local maven repository or corrupt). see here how refresh local maven repositories.

if you're not using build manager such maven, need manually download jar file, matching version existing spring jar files.
