这章我们来介绍在系统中引入redisson-spring-boot-starter依赖来实现redis缓存管理
1、在GitEgg-Platform中新建gitegg-platform-redis用于管理工程中用到的Redis公共及通用方法。
<!-- redisson Redis客户端--> <dependency> <groupId>org.redisson</groupId> <artifactId>redisson-spring-boot-starter</artifactId> </dependency>
2、在gitegg-platform-bom的pom.xml文件中添加gitegg-platform-redis
<!-- gitegg cache自定义扩展 --> <dependency> <groupId>com.gitegg.platform</groupId> <artifactId>gitegg-platform-redis</artifactId> <version>${gitegg.project.version}</version> </dependency>
3、GitEgg-Platform重新install，在GitEgg-Cloud子工程gitegg-service-system代码SystemController.java中添加设置和获取缓存的测试方法
private final RedissonClient redisson; private final RedisTemplate<String, String> template; @ApiOperation(value = "缓存测试设置值") @GetMapping(value = "redis/set") public Result redisSet(@RequestParam("id") String id) { RMap<String, String> m = redisson.getMap("test", StringCodec.INSTANCE); m.put("1", id); return Result.success("设置成功"); } @ApiOperation(value = "缓存测试获取值") @GetMapping(value = "redis/get") public Result redisGet() { BoundHashOperations<String, String, String> hash = template.boundHashOps("test"); String t = hash.get("1"); return Result.success(t); }
4、gitegg-service-system中的GitEggSystemApplication.java添加@EnableCaching注解
package com.gitegg.service.system; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cache.annotation.EnableCaching; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.context.annotation.ComponentScan; /** * gitegg-system 启动类 */ @EnableDiscoveryClient @ComponentScan(basePackages = "com.gitegg") @MapperScan("com.gitegg.*.*.mapper") @SpringBootApplication @EnableCaching public class GitEggSystemApplication { public static void main(String[] args) { SpringApplication.run(GitEggSystemApplication.class,args); } }
5、在Nacos配置文件中添加redis的相关配置，这里使用单机版redis，其他模式配置请参考官方文档
spring: redis: database: 1 host: 127.0.0.1 port: 6379 password: root ssl: false timeout: 2000 redisson: config: | singleServerConfig: idleConnectionTimeout: 10000 connectTimeout: 10000 timeout: 3000 retryAttempts: 3 retryInterval: 1500 password: root subscriptionsPerConnection: 5 clientName: null address: "redis://127.0.0.1:6379" subscriptionConnectionMinimumIdleSize: 1 subscriptionConnectionPoolSize: 50 connectionMinimumIdleSize: 32 connectionPoolSize: 64 database: 0 dnsMonitoringInterval: 5000 threads: 0 nettyThreads: 0 codec: !<org.redisson.codec.JsonJacksonCodec> {} "transportMode":"NIO"
6、启动项目，使用swagger进行测试

通过以上设置的值和获取的结果可知，我们配置的缓存已生效。
