今天給大家?guī)淼氖顷P于Java的相關知識,文章圍繞著SpringBoot是如何整合SpringDataRedis展開,文中有非常詳細的介紹及代碼示例,需要的朋友可以參考下

一、創(chuàng)建項目添加依賴

創(chuàng)建SpringBoot項目，并添加如下依賴:

<dependencies>
    <!-- springBoot 的啟動器 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- Spring Data Redis 的啟動器 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
 
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>
</dependencies>

二、設置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的配置類

添加Redis的java配置類，設置相關的信息。

/**
 * @program: springboot-redis-demo
 * @description: Redis的配置類
 * @author: 波波烤鴨
 * @create: 2019-05-20 23:40
 */
@Configuration
public class RedisConfig {
 
    /**
     * 1.創(chuàng)建JedisPoolConfig對象。在該對象中完成一些鏈接池配置
     * @ConfigurationProperties:會將前綴相同的內容創(chuàng)建一個實體。
     */
    @Bean
    @ConfigurationProperties(prefix="spring.redis.pool")
    public JedisPoolConfig jedisPoolConfig(){
        JedisPoolConfig config = new JedisPoolConfig();
		/*//最大空閑數
		config.setMaxIdle(10);
		//最小空閑數
		config.setMinIdle(5);
		//最大鏈接數
		config.setMaxTotal(20);*/
        System.out.println("默認值："+config.getMaxIdle());
        System.out.println("默認值："+config.getMinIdle());
        System.out.println("默認值："+config.getMaxTotal());
        return config;
    }
 
    /**
     * 2.創(chuàng)建JedisConnectionFactory：配置redis鏈接信息
     */
    @Bean
    @ConfigurationProperties(prefix="spring.redis")
    public JedisConnectionFactory jedisConnectionFactory(JedisPoolConfig config){
        System.out.println("配置完畢："+config.getMaxIdle());
        System.out.println("配置完畢："+config.getMinIdle());
        System.out.println("配置完畢："+config.getMaxTotal());
 
        JedisConnectionFactory factory = new JedisConnectionFactory();
        //關聯鏈接池的配置對象
        factory.setPoolConfig(config);
        //配置鏈接Redis的信息
        //主機地址
		/*factory.setHostName("192.168.70.128");
		//端口
		factory.setPort(6379);*/
        return factory;
    }
 
    /**
     * 3.創(chuàng)建RedisTemplate:用于執(zhí)行Redis操作的方法
     */
    @Bean
    public RedisTemplate<String,Object> redisTemplate(JedisConnectionFactory factory){
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        //關聯
        template.setConnectionFactory(factory);
 
        //為key設置序列化器
        template.setKeySerializer(new StringRedisSerializer());
        //為value設置序列化器
        template.setValueSerializer(new StringRedisSerializer());
 
        return template;
    }
}

四、添加pojo

/**
 * @program: springboot-redis-demo
 * @description: Users
 * @author: 波波烤鴨
 * @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、單元測試

@RunWith(SpringRunner.class)
@SpringBootTest(classes = SpringbootRedisDemoApplication.class)
public class SpringbootRedisDemoApplicationTests {
 
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;
 
    /**
     * 添加一個字符串
     */
    @Test
    public void testSet(){
        this.redisTemplate.opsForValue().set("key", "bobokaoya...");
    }
 
    /**
     * 獲取一個字符串
     */
    @Test
    public void testGet(){
        String value = (String)this.redisTemplate.opsForValue().get("key");
        System.out.println(value);
    }
 
    /**
     * 添加Users對象
     */
    @Test
    public void testSetUesrs(){
        Users users = new Users();
        users.setAge(20);
        users.setName("張三豐");
        users.setId(1);
        //重新設置序列化器
        this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
        this.redisTemplate.opsForValue().set("users", users);
    }
 
    /**
     * 取Users對象
     */
    @Test
    public void testGetUsers(){
        //重新設置序列化器
        this.redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
        Users users = (Users)this.redisTemplate.opsForValue().get("users");
        System.out.println(users);
    }
 
    /**
     * 基于JSON格式存Users對象
     */
    @Test
    public void testSetUsersUseJSON(){
        Users users = new Users();
        users.setAge(20);
        users.setName("李四豐");
        users.setId(1);
        this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class));
        this.redisTemplate.opsForValue().set("users_json", users);
    }
 
    /**
     * 基于JSON格式取Users對象
     */
    @Test
    public void testGetUseJSON(){
        this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class));
        Users users = (Users)this.redisTemplate.opsForValue().get("users_json");
        System.out.println(users);
    }
 
}
