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 |
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 spring-learn-integration-datajpa-redis Spring DataJPA Redis教程(基础版) org.springframework.boot spring-boot-starter-web ${dependency.springboot2.common.version} org.springframework.boot spring-boot-starter-data-redis ${dependency.springboot2.common.version} org.projectlombok lombok ${dependency.lombok.version} redis.clients jedis ${dependency.jedis.version} io.lettuce lettuce-core ${dependency.lettuce.version} org.springframework.boot spring-boot-maven-plugin ${dependency.springboot2.common.version} true org.apache.maven.plugins maven-compiler-plugin ${plugin.maven.compiler.version} ${system.java.version}
spring-boot-starter-data-redis整合Redis需要的依赖包,或者多带带使用spring-data-redis和jedis依赖包
一个简单的应用类

*/ @SpringBootApplication public class SpringBootDataJPARedisIntegration { public static void main(String[] args) { SpringApplication.run(SpringBootDataJPARedisIntegration.class, args); } }
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

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

*/ @RestController @RequestMapping(value = "redis") public class RedisController { @Autowired private RedisSupport support; @GetMapping public Object get() { return this.support.findAll(); } @PostMapping public Object post(@RequestBody RedisModel mode) { return this.support.save(mode); } @PutMapping public Object put(@RequestBody RedisModel mode) { return this.support.save(mode); } @DeleteMapping public Object delete(@RequestParam String id) { this.support.deleteById(id); return "SUCCESS"; } }
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
