spring+activiti 注入servici问题

Question

测试调用空指针异常。断点查看，自己封装的方法ActivitiInter，repositoryService为null
应该是说明这个repositoryService没有注入进来。
具体哪出的问题呢？

以下为配置和代码

application.xml中Activiti配置

    <property name="dataSource" ref="dataSource" />

    <property name="transactionManager" ref="transactionManager" />

    <property name="databaseSchemaUpdate" value="true" />
</bean>

<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
    <property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>

<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="formService" factory-bean="processEngine" factory-method="getFormService" />

Activiti服务封装的接口：



package com.ln.web.activiti;

import java.util.List;

import org.activiti.engine.FormService;
import org.activiti.engine.HistoryService;
import org.activiti.engine.RepositoryService;

测试调用：
package com.ln.web.controller;

import org.activiti.engine.repository.Deployment;
import org.junit.Test;

import com.ln.web.activiti.ActivitiInter;

public class ActivitiTest2 extends TestBase{

@Test
public void eployment(){
    ActivitiInter act=new ActivitiInter();
    act.deployProcDefByPath("bpmn/MyProcess.bpmn");
    act.startProcessInstanceByKey("myProcess");
}
