Redis之通过RedisTemplate对象访问Redis

Redis之通过RedisTemplate对象访问Redis

spring框架中

首先导入依赖

        
        
            redis.clients
            jedis
            2.9.1
        
        
        
            org.springframework.data
            spring-data-redis
            2.1.10.RELEASE
        
        
        
            com.fasterxml.jackson.core
            jackson-databind
            2.10.2
        

配置application.xml文件

测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(value = "classpath:application.xml")
public class AppTest {

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void testStr() {
        //默认使用的是JDK序列化的编码
        redisTemplate.opsForValue().set("username", "hello");
        String result = (String) redisTemplate.opsForValue().get("username");
        System.out.println(result);
        redisTemplate.opsForValue().set("age", 20);
        System.out.println(redisTemplate.opsForValue().increment("age"));
    }

    @Test
    public void testEmp() {
        Emp emp = new Emp(1001, "hello", new Date());
        redisTemplate.opsForValue().set("emp:" + emp.getEmpno(), emp);
        Emp result = (Emp) redisTemplate.opsForValue().get("emp:1001");
        System.out.println(result.getEname() + ":" + result.getHiredate());
    }

    @Test
    public void testAddEmps() {
        List emps = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            Emp emp = new Emp(i, "hello" + i, new Date());
            emps.add(emp);
        }
        redisTemplate.opsForValue().set("emps", emps);
        List list = (List) redisTemplate.opsForValue().get("emps");
        for (Emp emp : list) {
            System.out.println(emp.getEname());
        }
    }

    @Test
    public void testHash() {
        redisTemplate.opsForHash().put("emp", "ename", "张三");
        String ename = (String) redisTemplate.opsForHash().get("emp", "ename");
        System.out.println(ename);
        RedisOperations redisOperations = redisTemplate.opsForHash().getOperations();
        String empName = redisOperations.boundValueOps("ename").get();
        System.out.println(empName);
        Map result = redisTemplate.opsForHash().entries("emp");
        for (String key : result.keySet()) {
            System.out.println(key + ":" + result.get(key));
        }
        Emp emp = new Emp(1001, "张三", new Date());
        Map empMap = new HashMap();
        empMap.put("ename", emp.getEname());
        empMap.put("empno", emp.getEmpno());
        empMap.put("hiredate", emp.getHiredate());
        redisTemplate.opsForHash().putAll("empmap", empMap);
        redisTemplate.opsForHash().entries("empmap");

    }


    @Test

springboot项目中

导入依赖
使用配置类配置Jedis和RedisTemplate
具体的有时间再写
