SpringBoot整合SpringDataRedis代码示例

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 RedisTemplate redisTemplate(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 RedisTemplate redisTemplate;
 
    /**
     * 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);
    }
 
}
