## 1 创建项目，导入jar包 ##

jar包

## 2 编写配置文件 ##

redis.properties

redis.pool.maxTotal=20
    redis.pool.maxIdle=10
    redis.pool.minIdle=5
    redis.conn.hostName=127.0.0.1
    redis.conn.port=6379

    </beans>

## 3 测试 ##

在运行之前先开启redis-server，创建一个Users对象

package per.czt.test;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
    import org.springframework.data.redis.serializer.JdkSerializationRedisSerializer;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    import per.czt.pojo.Users;
    
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration("classpath:applicationContext.xml")
    public class RedisTest {
    	@Autowired
    	private RedisTemplate<String,Object> redisTemplate;
    	/*
    	 * 添加键值对
    	 */
    	/*@Test
    	public void test() {
    		redisTemplate.opsForValue().set("key", "test");;
    		
    	}*/
    	/*
    	 * 获取redis中的数据
    	 */
    
    	@Test
    	public void test1() {
    		String value=(String) redisTemplate.opsForValue().get("key");
    		System.out.println(value);
    	}
    	/*
    	 * 添加users
    	 */
    	
    	/*@Test
    	  public void test2() {
    		Users users=new Users();
    		users.setUserid(2);
            users.setUserage(13);
            users.setUsername("张三");
            //对值做jdk序列化处理
            this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
            this.redisTemplate.opsForValue().set("user", users);
    	}*/
    	/*
    	 * 获取Users
    	 */
    	@Test
    	public void test3() {
    	     //对值做jdk序列化处理
    		this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
    		Users users=(Users) this.redisTemplate.opsForValue().get("user");
    		System.out.println(users);
    	}
    	/*
    	 * 添加Users json格式
    	 */
    	/*@Test
    	public void test4() {
    		Users users=new Users();
    		users.setUserid(9);
            users.setUserage(18);
            users.setUsername("李四");
             //对值做jackson序列化处理，转换为json格式
            this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class));
            
            this.redisTemplate.opsForValue().set("usersjson",users);
            
    	}*/
    	/*
    	 * 获取Users json格式
    	 */
    	@Test
    	public void test5() {
    	    //对值做jackson序列化处理，转换为json格式
    		this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class));
    		Users users=(Users) this.redisTemplate.opsForValue().get("usersjson");
    		System.out.println(users);
    	}
    }
