springboot+redis（注解方式）使用（java代码部分）

pop.xml文件配置----使用maven导入依赖的包

<dependency>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-data-redis</artifactId>

</dependency>

application.properties---redis配置

#redis

spring.redis.host=127.0.0.1

spring.redis.port=6379

spring.redis.password=pw

spring.redis.maxIdle=100

spring.redis.maxActive=300

spring.redis.maxWait=1000

spring.redis.testOnBorrow=true

spring.redis.timeout=10000

测试类

@Cacheable(value = "s830_user" , key="'user_'+#usercode")

    public User redisQueryUser(String usercode)

    {

        User user = userService.getUser(usercode);

        return user;

    }

maven启动类：

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

import org.springframework.cloud.netflix.feign.EnableFeignClients;

@SpringBootApplication
@EnableDiscoveryClient

public class Application 

{

    public static void main( String[] args )

    {

    SpringApplication.run(Application.class, args);

    }

}
