spring+redis 报NullPointerException异常

小弟在使用Spring的spring-data-redis来操作redis缓存时遇到下面这个问题，麻烦各位大侠帮助解惑一下：
application.xml配置文件如下：



<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

	<bean id="userServiceImpl" class="yyuap.redis.spring.service.UserServiceImpl"></bean>

</beans>

UserServiceImpl类如下：



package yyuap.redis.spring.service;



import org.springframework.cache.annotation.CachePut;

import org.springframework.cache.annotation.Cacheable;

import org.springframework.util.StringUtils;



import yyuap.redis.spring.model.UserEntity;



/**

 * 业务层接口实现

 * @author leo

 *

 */

public class UserServiceImpl {

	

	private static final String  cacheKey  ="userEntity";

	

	/**

	 * 新增

	 * @param entity

	 * @return

	 * @CachePut 这个注释可以确保方法被执行，同时方法的返回值也被记录到缓存中，实现缓存与数据库的同步更新。

	 */

	@CachePut(key ="#entity.getUserId()",value ="entity")  

	public void addUserEntity(UserEntity entity) {

		//非空

		if(entity ==null || StringUtils.isEmpty(entity.getUserId())){

		}

		/**

		 * 做数据库持久化，这里就无需再申明了

		 */

		System.out.println("先插入数据库中,.........");

		

	}

}

UserEntiy实体类如下：



package yyuap.redis.spring.model;

/**

 * 用户实体类

 * @author leo

 *

 */

public class UserEntity {

	//用户id

	private String userId;

	//用户账号

	private String EmpCode;

	//用户名称

	private String EmpName;

	//用户角色

	private String role;

	//职位

	private String title;

	public String getUserId() {

		return userId;

	}

	public void setUserId(String userId) {

		this.userId = userId;

	}

	public String getEmpCode() {

		return EmpCode;

	}

	public void setEmpCode(String empCode) {

		EmpCode = empCode;

	}

	public String getEmpName() {

		return EmpName;

	}

	public void setEmpName(String empName) {

		EmpName = empName;

	}

	public String getRole() {

		return role;

	}

	public void setRole(String role) {

		this.role = role;

	}

	public String getTitle() {

		return title;

	}

	public void setTitle(String title) {

		this.title = title;

	}

}

测试类如下：



package yyuap.redis.spring;

import org.junit.After;

import org.junit.Before;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;



import yyuap.redis.spring.model.UserEntity;

import yyuap.redis.spring.service.UserServiceImpl;





@RunWith(SpringJUnit4ClassRunner.class)  

@ContextConfiguration(locations={"classpath:applicationContext.xml"})

public class TestUserServiceImpl extends AbstractJUnit4SpringContextTests{

	

	@Autowired

	private UserServiceImpl userServiceImpl;

	

	@Test

	public void testAddUser(){

		UserEntity entity = new UserEntity();

		entity.setUserId("000003");

		entity.setEmpCode("130566");

		entity.setEmpName("leonardo-zeng");

		entity.setRole("Java Development Engineer");

		entity.setTitle("PM");

		userServiceImpl.addUserEntity(entity);

	}
