本篇文章小编给大家分享一下SpringBoot整合SpringDataRedis代码示例,文章代码介绍的很详细,小编觉得挺不错的,现在分享给大家供大家参考,有需要的小伙伴们可以来看看。
一、创建项目添加依赖
创建SpringBoot项目,并添加如下依赖:
org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-data-redis org.springframework.boot spring-boot-starter-test test redis.clients jedis 2.9.0
二、设置application.properties文件
spring.redis.jedis.pool.max-idle=10 spring.redis.jedis.pool.min-idle=5 spring.redis.pool.max-total=20 spring.redis.hostName=192.168.88.120 spring.redis.port=6379
三、添加Redis的配置类
添加Redis的java配置类,设置相关的信息。
/** * @program: springboot-redis-demo * @description: Redis的配置类 * @author: 烤鸭 * @create: 2019-05-20 23:40 */ @Configuration public class RedisConfig { /** * 1.创建JedisPoolConfig对象。在该对象中完成一些链接池配置 * @ConfigurationProperties:会将前缀相同的内容创建一个实体。 */ @Bean @ConfigurationProperties(prefix="spring.redis.pool") public JedisPoolConfig jedisPoolConfig(){ JedisPoolConfig config = new JedisPoolConfig(); /*//最大空闲数 config.setMaxIdle(10); //最小空闲数 config.setMinIdle(5); //最大链接数 config.setMaxTotal(20);*/ System.out.println("默认值:"+config.getMaxIdle()); System.out.println("默认值:"+config.getMinIdle()); System.out.println("默认值:"+config.getMaxTotal()); return config; } /** * 2.创建JedisConnectionFactory:配置redis链接信息 */ @Bean @ConfigurationProperties(prefix="spring.redis") public JedisConnectionFactory jedisConnectionFactory(JedisPoolConfig config){ System.out.println("配置完毕:"+config.getMaxIdle()); System.out.println("配置完毕:"+config.getMinIdle()); System.out.println("配置完毕:"+config.getMaxTotal()); JedisConnectionFactory factory = new JedisConnectionFactory(); //关联链接池的配置对象 factory.setPoolConfig(config); //配置链接Redis的信息 //主机地址 /*factory.setHostName("192.168.70.128"); //端口 factory.setPort(6379);*/ return factory; } /** * 3.创建RedisTemplate:用于执行Redis操作的方法 */ @Bean public RedisTemplateredisTemplate(JedisConnectionFactory factory){ RedisTemplate template = new RedisTemplate<>(); //关联 template.setConnectionFactory(factory); //为key设置序列化器 template.setKeySerializer(new StringRedisSerializer()); //为value设置序列化器 template.setValueSerializer(new StringRedisSerializer()); return template; } }
四、添加pojo
/** * @program: springboot-redis-demo * @description: Users * @author: 烤鸭 * @create: 2019-05-20 23:47 */ public class Users implements Serializable { private Integer id; private String name; private Integer age; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } @Override public String toString() { return "Users [id=" + id + ", name=" + name + ", age=" + age + "]"; } }
五、单元测试
@RunWith(SpringRunner.class) @SpringBootTest(classes = SpringbootRedisDemoApplication.class) public class SpringbootRedisDemoApplicationTests { @Autowired private RedisTemplateredisTemplate; /** * 添加一个字符串 */ @Test public void testSet(){ this.redisTemplate.opsForValue().set("key", "bobokaoya..."); } /** * 获取一个字符串 */ @Test public void testGet(){ String value = (String)this.redisTemplate.opsForValue().get("key"); System.out.println(value); } /** * 添加Users对象 */ @Test public void testSetUesrs(){ Users users = new Users(); users.setAge(20); users.setName("张三丰"); users.setId(1); //重新设置序列化器 this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer()); this.redisTemplate.opsForValue().set("users", users); } /** * 取Users对象 */ @Test public void testGetUsers(){ //重新设置序列化器 this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer()); Users users = (Users)this.redisTemplate.opsForValue().get("users"); System.out.println(users); } /** * 基于JSON格式存Users对象 */ @Test public void testSetUsersUseJSON(){ Users users = new Users(); users.setAge(20); users.setName("李四丰"); users.setId(1); this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class)); this.redisTemplate.opsForValue().set("users_json", users); } /** * 基于JSON格式取Users对象 */ @Test public void testGetUseJSON(){ this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class)); Users users = (Users)this.redisTemplate.opsForValue().get("users_json"); System.out.println(users); } }
