Spring DataJPA Redis教程(基础版)

本教程主要详细讲解Spring Data Redis,它向Redis提供Spring Data平台的抽象.

Redis由基于key/value库的数据结构存数，以持久保存数据，并可用作数据库，缓存，消息代理等。

基础环境

---

技术	版本
Java	1.8+
SpringBoot	2.x.x
DataJPA	2.x.x
Jedis	2.9.x

创建项目

---

• 初始化项目

mvn archetype:generate -DgroupId=com.edurt.sli.slidr -DartifactId=spring-learn-integration-datajpa-redis -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0.0 -DinteractiveMode=false

• 修改pom.xml增加redis的支持

    
        spring-learn-integration-datajpa
        com.edurt.sli
        1.0.0
    

    4.0.0

                    ${system.java.version}
                
            
        
    

spring-boot-starter-data-redis整合Redis需要的依赖包,或者单独使用spring-data-redis和jedis依赖包

• 一个简单的应用类

    public static void main(String[] args) {
        SpringApplication.run(SpringBootDataJPARedisIntegration.class, args);

}

配置支持Redis

---

• 在resources资源目录下创建一个application.properties的配置文件,内容如下

spring.redis.host=localhost
spring.redis.port=6379
spring.redis.database=0
spring.redis.jedis.pool.max-active=8
spring.redis.jedis.pool.max-wait=1ms
spring.redis.lettuce.pool.max-active=8
spring.redis.jedis.pool.min-idle=0

操作Redis数据

---

• 在/src/main/java/com/edurt/sli/slidr目录下创建model目录,并在该目录下新建RedisModel文件

@RedisHash(value = "Redis")
@Data
@ToString
@AllArgsConstructor
@NoArgsConstructor
public class RedisModel {

    @Id
    private String id;
    private String name;

}

@RedisHash为每个数据库创建域类的空子类。

@Id注解的属性和被命名为id的属性会被当作标识属性

• 在/src/main/java/com/edurt/sli/slidr目录下创建repository目录,并在该目录下新建RedisSupport文件

public interface RedisSupport extends CrudRepository {

在CrudRepository中提供了一些基础的增删改查的功能.

• 测试增删改查的功能

在/src/main/java/com/edurt/sli/slidr目录下创建controller目录,并在该目录下新建RedisController文件

添加数据

shicheng@shichengdeMacBook-Pro ~> curl -X POST http://localhost:8080/redis -H 'Content-Type:application/json' -d '{"id": "1", "name": "Hello Redis"}'
{"id":"1","name":"Hello Redis"}⏎

修改数据

shicheng@shichengdeMacBook-Pro ~> curl -X PUT http://localhost:8080/redis -H 'Content-Type:application/json' -d '{"id": "1", "name": "Hello Redis Modfiy"}'
{"id":"1","name":"Hello Redis Modfiy"}⏎

获取数据

shicheng@shichengdeMacBook-Pro ~> curl -X GET http://localhost:8080/redis
[{"id":"1","name":"Hello Redis Modfiy"}]⏎

删除数据

shicheng@shichengdeMacBook-Pro ~> curl -X DELETE 'http://localhost:8080/redis?id=1'
SUCCESS⏎

打包文件部署

---

• 打包数据

mvn clean package -Dmaven.test.skip=true -X

运行打包后的文件即可

java -jar spring-learn-integration-datajpa/spring-learn-integration-datajpa-redis/target/spring-learn-integration-datajpa-redis-1.0.0.jar
