一、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>
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。
@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;
}
}
四、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 + "]";
}
}
五、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);
}
}
