Spring autowire null值

Question

我遇到弹簧自动装配组件的问题。我尝试将bean（UserRepository）注入java类Reader。当我使用autowire注释时，对象总是为空。我尝试添加到spring-config.xml bean'reader'whith属性'userRepository'但这不起作用。缺少什么？

弹簧-config.xml中：

<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<context:component-scan base-package="reader" />
<context:annotation-config/>

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.sqlite.JDBC"/>
    <property name="url" value="jdbc:sqlite:C:/Users/Piotr/Downloads/projekt na projekt/IntelliDOM/IntelliDOM.sqlite"/>
    <property name="username" value=""/>
    <property name="password" value=""/>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="userRepository" class="repository.UserRepositoryHibernate">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

</beans>

Reader.java：

@Service
@Path("/")
public class Reader {

@Autowired
private UserRepository userRepository;

@GET
@Path("/test")
public void test(){
    System.out.println("test");
    userRepository.findAll(); //this is allways null
}

@POST
@Path("/dom2")
public Response read(String nonParsedWords){
    Words parsedWords = WordParser.parseWords(nonParsedWords);

    for(String word : parsedWords.getWords()){
        System.out.println(word);
    }
    return Response.status(200).entity(nonParsedWords).build();
}

public void setUserRepository(UserRepository userRepository) {
    this.userRepository = userRepository;
}
}

申请环境有问题吗？为什么这个豆子不能注射？ 春季版：2.5.6
