Jedis API来操作redis
利用Jedis API来操作redis
1. 导入依赖
|
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.3.20.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.3.20.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.20.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.20.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> <version>4.3.20.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.3.20.RELEASE</version> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> <!-- 返回json字符串的支持 --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.8</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.3.0.RELEASE</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> |
2. 把相关的类交给spring容器管理
|
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <!-- 最大空闲连接数 --> <property name="maxIdle" value="3" /> <!-- 最大连接数 --> <property name="maxTotal" value="5" /> <!-- 连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true --> <property name="blockWhenExhausted" value="true" /> <!-- 获取连接时的最大等待毫秒数(如果设置为阻塞时BlockWhenExhausted),如果超时就抛异常, 小于零:阻塞不确定的时间, 默认-1 --> <property name="maxWaitMillis" value="30000" /> <!-- 在获取连接的时候检查有效性 --> <property name="testOnBorrow" value="true" /> </bean>
<bean id="jedisPool" class="redis.clients.jedis.JedisPool" destroy-method="close"> <constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg> <constructor-arg name="host" value="192.168.18.201" /> <constructor-arg name="port" value="6379" /> <constructor-arg name="timeout" value="30000" /> <constructor-arg name="password" value="123456"></constructor-arg> </bean> |
3. 测试
|
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext.xml") public class JedisTest {
@Autowired private JedisPool jedisPool; @Test public void testAdd(){ Jedis jedis = jedisPool.getResource(); jedis.set("name","wangwu"); jedis.close(); } @Test public void testAddPerson(){ Person person=new Person(100,"张三","男",22,new Date()); Jedis jedis = jedisPool.getResource(); // jedis.set("person", JsonUtils.objectToJson(person)); jedis.hset("persons",person.getName(),JsonUtils.objectToJson(person)); jedis.close(); }
@Test public void testAddPerson2(){
Jedis jedis = jedisPool.getResource(); String jsonData=jedis.get("person"); Person person=JsonUtils.jsonToEntity(jsonData,Person.class); System.out.println(person); jedis.close(); } }
