package fr.aaa;  import org.springframework.context.applicationcontext; import org.springframework.context.support.classpathxmlapplicationcontext; import org.springframework.stereotype.component;  @component public class computation {      public computation() {     }      public static void main(string[] args) {         applicationcontext context = new classpathxmlapplicationcontext("classpath*:applicationcontext.xml");         computation computer = context.getbean(computation.class);     } } 

and applicationcontext.xml file :

<?xml version="1.0" encoding="utf-8"?>  <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xmlns:security="http://www.springframework.org/schema/security" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"  xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd     http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.3.xsd">    <import resource="classpath:spring/persistence.xml"/>  <context:annotation-config /> <context:component-scan base-package="fr.aaa.*, com.bbb.*"/>   <util:properties id="jdbcprops" location="jdbc.properties" />     <bean id="propertyconfigurer"     class="org.springframework.beans.factory.config.propertyplaceholderconfigurer">     <property name="locations">         <list>          <value>classpath:configuration.properties</value>          <value>classpath:jdbc.properties</value>         </list>     </property> </bean> 

i exception :

exception in thread "main" org.springframework.beans.factory.nosuchbeandefinitionexception: no unique bean of type [fr.aaa.computation] defined: expected single bean found 0: 

am missing here ?

change

fr.aaa.* 

to

fr.aaa 

do same thing packages.

the base-package attribute is

the comma-separated list of packages scan annotated components. 

there no wildcards involved. have use specific name of package. spring take care of scanning sub packages.
