使用的包：

<dependency>
    			<groupId>org.springframework</groupId>
    			<artifactId>spring-test</artifactId>
    			<version>3.1.2.RELEASE</version>
    			<scope>test</scope>
    		</dependency>
    		<dependency>
    			<groupId>junit</groupId>
    			<artifactId>junit</artifactId>
    			<version>4.8.2</version>
    			<scope>test</scope>
    		</dependency>

<dependency>
    			<groupId>org.springframework.data</groupId>
    			<artifactId>spring-data-redis</artifactId>
    			<version>1.7.11.RELEASE</version>
    		</dependency>
    		<dependency>
    			<groupId>redis.clients</groupId>
    			<artifactId>jedis</artifactId>
    			<version>2.9.0</version>
    		</dependency>

redis数据库参数：

###Redis缓存配置
    #缓存池最小空闲数
    redis.minIdle=5
    #缓存池最大空闲数
    redis.maxIdle=100
    #缓存池最大连接数
    redis.maxTotal=300
    #最大等待时间
    redis.maxWaitMillis=3000
    #使用连接时是否测试可用
    redis.testOnBorrow=true
    #主机地址
    redis.host=127.0.0.1
    #主机端口
    redis.port=6379
    #主机密码
    redis.password=123456
    #数据库下标
    redis.database=4

redis.xml的配置，这里只有redis简单的配置，关于spring另外配置，

<?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:cache="http://www.springframework.org/schema/cache"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans 
    						http://www.springframework.org/schema/beans/spring-beans.xsd 
    						http://www.springframework.org/schema/cache 
    						http://www.springframework.org/schema/cache/spring-cache-3.2.xsd">
    						
        
    	<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
    		
    		<property name="minIdle" value="${redis.minIdle}" />
    		
    		<property name="maxIdle" value="${redis.maxIdle}" />
    		
    		<property name="maxTotal" value="${redis.maxTotal}" />
    		
    		<property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
    		
    		<property name="testOnBorrow" value="${redis.testOnBorrow}" />
    	</bean>
    	
    	
    	<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
    		<property name="poolConfig" ref="poolConfig" />
    		<property name="database" value="${redis.database}" />
    		<property name="port" value="${redis.port}" />
    		<property name="hostName" value="${redis.host}" />
    		<property name="password" value="${redis.password}" />
    	</bean>
    	
    	
    	<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
    		<property name="connectionFactory" ref="jedisConnectionFactory" />
    	</bean>
        
    </beans>

redis的实现代码，使用了redisTemplate,这里基本代码学习的一个网友的

package org.gyy.entity.user;
    
    import java.io.Serializable;
    
    
    public class User implements Serializable{
    
    	
    	/**
    	 * 
    	 */
    	private static final long serialVersionUID = -5528480600517508340L;
    	private String id;
    	private String name;
    	private String password;
    	
    	public User() {
    		super();
    	}
    	public User(String id, String name, String password) {
    		super();
    		this.id = id;
    		this.name = name;
    		this.password = password;
    	}
    	public String getId() {
    		return id;
    	}
    	public void setId(String id) {
    		this.id = id;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getPassword() {
    		return password;
    	}
    	public void setPassword(String password) {
    		this.password = password;
    	}
    	@Override
    	public String toString() {
    		return "User [id=" + id + ", name=" + name + ", password=" + password + "]";
    	}
    	
    	
    	
    }

package org.gyy.redis;
    
    import javax.annotation.Resource;
    
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.RedisSerializer;
    
    public abstract class AbstractBaseRedisDao<K,V> {
    	@Resource
    	protected RedisTemplate<K, V> redisTemplate;
    /**

     * @return
     */
    	public RedisSerializer<String> getRedisSerializer() {
    		return redisTemplate.getStringSerializer();
    	}
    /**
     * 设置redis
     * @param redisTemplate
     */
    	public void setRedisTemplate(RedisTemplate<K, V> redisTemplate) {
    		this.redisTemplate = redisTemplate;
    	}
    	
    	
    }

package org.gyy.redis.dao;
    
    import java.util.List;
    
    import org.gyy.entity.user.User;

    				return connection.setNX(key, name);
    			}
    		});
    		return result;
    	}
    
    	@Override
    	public boolean add(List<User> list) {
    		// TODO Auto-generated method stub
    		Assert.notEmpty(list);
    		boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
    
    			@Override
    			public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
    				// TODO Auto-generated method stub
    				RedisSerializer<String> serializer = getRedisSerializer();
    				for (User user : list) {
    					byte[] key = serializer.serialize(user.getId());
    					byte[] name = serializer.serialize(user.getName());
    					connection.setNX(key, name);
    				}
    				return true;
    			}
    		},false,true);
    		return result;
    	}
    
    	@Override
    	public void delete(String key) {
    		// TODO Auto-generated method stub
    		redisTemplate.delete(key);
    	}

    		}
    		boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {

    				return true;
    			}
    		});
    		return result;
    	}
    
    	@Override

    				return new User(keyId,name,null);
    			}
    		});
    		return result;
    	}
    
    }

后面的测试部分使用的是spring-test和junit4做的单元测试，以前没有注意，突然觉得spring-test很安逸

package org.gyy.baseTest;
    
    import org.junit.runner.RunWith;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    @RunWith(SpringJUnit4ClassRunner.class)//使用junit4进行测试 
    @ContextConfiguration({"classpath*:applicationContext.xml"}) //加载配置文件  
    //------------如果加入以下代码，所有继承该类的测试类都会遵循该配置，也可以不加，在测试类的方法上///控制事务，参见下一个实例  
    //这个非常关键，如果不加入这个注解配置，事务控制就会完全失效！  
    //@Transactional  
    //这里的事务关联到配置文件中的事务控制器（transactionManager = "transactionManager"），同时//指定自动回滚（defaultRollback = true）。这样做操作的数据才不会污染数据库！  
    //@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)  
    //------------  
    public class BaseJunit4Test {
    
    }
