Spring Data Redis

第一步：创建项目，按如下所示添加Maven依赖：

    junit
    junit
    4.12
    test


    org.springframework
    spring-context
    5.0.5.RELEASE


    org.springframework
    spring-aop
    5.0.5.RELEASE


    org.springframework
    spring-tx
    5.0.5.RELEASE


    org.springframework
    spring-test
    5.0.5.RELEASE


    commons-logging
    commons-logging
    1.2


    org.springframework.data
    spring-data-redis
    2.0.7.RELEASE


    redis.clients
    jedis
    2.9.0


    com.fasterxml.jackson.core
    jackson-core
    2.9.5


    com.fasterxml.jackson.core
    jackson-databind
    2.9.5


    com.fasterxml.jackson.core
    jackson-annotations
    2.9.5

第二步：创建配置文件，代码如下： redis.properties

redis.pool.maxToal=20
redis.pool.maxIdel=10
redis.pool.minIdel=5
redis.conn.hostName= 127.0.0.1
redis.conn.port=6379
redis.conn.pass=

jedis.xml

第三步：创建实体类，代码如下：

public class Dept implements Serializable {
    private  Integer deptno;
    private String dname;
    private String loc;
    //…… getter/setter方法、toString()方法、默认构造方法、全参构造方法
}

第四步：测试代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/jedis.xml")
public class RedisTest {
    @Autowired
    private RedisTemplate redisTemplate;
    @Test
    public void fun1() {    //    向Redis添加字符串形式的健值对
        redisTemplate.opsForValue().set("name", "zhangsan");
    }
    @Test
    public void fun2() {
        Object name = redisTemplate.opsForValue().get("name");
        System.out.println(name);
    }
    @Test
    public void fun3() {
        Dept dept = new Dept(123, "sales", "new york");
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());//序列化器
        redisTemplate.opsForValue().set("dept", dept);
    }
    @Test
    public void fun4() {
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());//序列化器
        Dept dept = (Dept) redisTemplate.opsForValue().get("dept");
        System.out.println(dept);
    }
    @Test
    public void fun5() {
        Dept dept = new Dept(123, "sales", "new york");
        redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer(Dept.class)); 
        redisTemplate.opsForValue().set("dept", dept);
    }
    @Test
    public void fun6() {
        redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer(Dept.class)); 
        Dept dept = (Dept) redisTemplate.opsForValue().get("dept");
        System.out.println(dept);
    } 
}
