本文介绍下SpringBoot如何整合springDataRedis 框架的，SpringDataRedis具体的内容在前面已经介绍过了，可自行参考。

1.创建项目添加依赖

创建SpringBoot项目，并添加如下依赖:


<dependencies>
    <!-- springBoot 的启动器 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-WEB</artifactId>
    </dependency>
    <!-- Spring Data Redis 的启动器 -->
    <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>

2.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

3.添加Redis的配置类

添加Redis的java配置类，设置相关的信息。



@Configuration
public class RedisConfig {

    
    @Bean
    @ConfigurationProperties(prefix="spring.redis.pool")
    public JedisPoolConfig jedisPoolConfig(){
        JedisPoolConfig config = new JedisPoolConfig();
		
        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;
    }

    
    @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
		
        return factory;
    }

    
    @Bean
    public RedisTemplate<String,Object> redisTemplate(JedisConnectionFactory factory){
        RedisTemplate<String, Object> 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;
    }
}

4.添加pojo



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 + "]";
    }

}

5.单元测试


@RunWith(SpringRunner.class)
@SpringBootTest(classes = SpringbootRedisDemoApplication.class)
public class SpringbootRedisDemoApplicationTests {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    
    @Test
    public void testSet(){
        this.redisTemplate.opsForValue().set("key", "bobokaoya...");
    }

    
    @Test
    public void testGet(){
        String value = (String)this.redisTemplate.opsForValue().get("key");
        System.out.println(value);
    }

    
    @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);
    }

    
    @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);
    }

    
    @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);
    }

    
    @Test
    public void testGetUseJSON(){
        this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Users.class));
        Users users = (Users)this.redisTemplate.opsForValue().get("users_json");
        System.out.println(users);
    }

}
