java - Spring REST Service with IOC? -

in past did simple soap services using spring , ioc (application-context.xml state controller has 2 different daos etc. , spring sets them me)

now trying rest service using spring.

my controller looks this

@restcontroller @requestmapping("/") public class mycontroller {  private mydao1 mydao1; private mydao2 mydao2;  @requestmapping("/name") public mytest getgreeting() {     mytest tst = new mytest(1, "hallo ");     return tst; }   public void setmydao1(mydao1 mydao1) {     this.mydao1 = mydao1; }  public void setmydao2(mydao2 mydao2) {     this.mydao2 = mydao2; } 

my rest-servlet.xml contains this:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemalocation="     http://www.springframework.org/schema/beans          http://www.springframework.org/schema/beans/spring-beans-4.0.xsd     http://www.springframework.org/schema/context     http://www.springframework.org/schema/context/spring-context-4.0.xsd     http://www.springframework.org/schema/mvc     http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">  <!-- configure plugin json request , response in method handler --> <bean class="org.springframework.web.servlet.mvc.method.annotation.requestmappinghandleradapter">     <property name="messageconverters">         <list>             <ref bean="jsonmessageconverter" />         </list>     </property> </bean>  <!-- configure bean convert json pojo , vice versa --> <bean id="jsonmessageconverter" class="org.springframework.http.converter.json.mappingjackson2httpmessageconverter"> </bean>  <bean id="txmanager" class="org.springframework.jdbc.datasource.datasourcetransactionmanager">     <property name="datasource" ref="datasource" /> </bean>  <bean id="datasource" class="org.springframework.jndi.jndiobjectfactorybean">     <property name="jndiname" value="java:comp/env/jdbc/informixdb" />     <property name="resourceref" value="true" /> </bean>  <bean id="mydao1" class="com.test.dao.mydao1">     <property name="datasource" ref="datasource" /> </bean> <bean id="mydao2" class="com.test.dao.mydao2">     <property name="datasource" ref="datasource" /> </bean>   <bean id="mycontroller" class="com.test.controller.mycontroller">     <property name="mydao1" ref="mydao1" />     <property name="mydao2" ref="mydao2" /> </bean>   <context:component-scan base-package="com.test.controller.mycontroller" /> <mvc:annotation-driven /> 

now error

java.lang.illegalstateexception: ambiguous mapping found. cannot map 'mycontroller' bean method  public com.test.entity.mytest com.test.controller.mycontroller.getgreeting() {[//name],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}: there 'mycontroller' bean method public com.test.entity.mytest com.test.controller.mycontroller.getgreeting() mapped. 

when remove requestmapping annotations can deploy on tomcat don't know how call service

org.springframework.web.servlet.dispatcherservlet nohandlerfound warning: no mapping found http request uri [/mytestservice/getgreeting] in dispatcherservlet name 'rest' 

'rest' servlet map in web.xml

what missing?

you loading controller twice, , spring tries map twice :

• it declared in rest-servlet.xml
• it found annotated controller, due @restcontroller annotation , tag <context:component-scan base-package="de.cat.auftrag.controller" /> in rest-servlet.xml

you should either :

• remove declaration <bean id="mycontroller" ... rest-servlet.xml, have autowire daos
• remove <context:component-scan ... tag, if not have other bean scan.
