dependencies {
implementation 'org.springframework.boot:spring-boot-starter-data-redis'
implementation 'org.springframework.boot:spring-boot-starter-web'
implementation 'redis.clients:jedis:4.0.1'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
}
2.properties文件配置
spring.redis.database=0 spring.redis.host=127.0.0.1 spring.redis.port=6379 spring.redis.password= spring.redis.pool.max-active=8 spring.redis.pool.max-wait=-1 spring.redis.pool.max-idle=8 spring.redis.pool.min-idle=0 spring.redis.timeout=03.编解码器用来序列化和反序列化对象(如果不需要存储对象可以省略)
import org.springframework.core.convert.converter.Converter; import org.springframework.core.serializer.support.DeserializingConverter; import org.springframework.core.serializer.support.SerializingConverter; import org.springframework.data.redis.serializer.RedisSerializer; import org.springframework.data.redis.serializer.SerializationException; public class RedisObjectSerializer implements RedisSerializer4.编写配置类,装载并注入redisTemplate实例,代码如下
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;
@Configuration
public class redisConfig {
@Bean
RedisTemplate createRedisTemplate(RedisConnectionFactory redisConnectionFactory){
RedisTemplate template = new RedisTemplate();
template.setConnectionFactory(redisConnectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new RedisObjectSerializer());
return template;
}
}
5.使用RedisTemplate代码如下
import com.zqw.learnredies.bean.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.HashMap;
import java.util.Map;
@RestController
public class testController {
private RedisTemplate redisTemplate;
@Autowired
public void setRedisTemplate(RedisTemplate redisTemplate) {
this.redisTemplate = redisTemplate;
}
@GetMapping("/test")
public Map test(){
Map res = new HashMap<>();
redisTemplate.opsForValue().set("url", "http://www.zqwxsf.top");
res.put("usl",redisTemplate.opsForValue().get("url"));
User user = new User("C++", 40);
redisTemplate.opsForValue().set(user.name, user);
res.put(user.name,redisTemplate.opsForValue().get(user.name));
user = new User("Java", 30);
redisTemplate.opsForValue().set(user.name, user);
res.put(user.name,redisTemplate.opsForValue().get(user.name));
user = new User("python", 33);
redisTemplate.opsForValue().set(user.name, user);
res.put(user.name,redisTemplate.opsForValue().get(user.name));
return res;
}
}
user类如下
import java.io.Serializable;
public class User implements Serializable {
public String name;
public int age;
public User() {
}
public User(String name, int age) {
this.name = name;
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
运行结果如下
