（转）spring boot整合redis

一篇写的更清晰的文章，包括redis序列化：http://makaidong.com/ncjava/330749_5285125.html

1.项目目录结构

2、引入所需jar包

<!-- Spring Boot 使用 Redis 缓存 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

3.配置文件

application.yml

testName:
  applicationName: testRedis
spring:
  redis:
    host: 192.168.200.108
    port: 6379

redis.properties

host=192.168.200.108
port=6379
connectionTimeout=5000
soTimeout=5000
database=0

build.gradle

group 'springBootDemo'
version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'war'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile("junit:junit:$springJunit")
    compile("org.springframework.boot:spring-boot-starter-web:$springBootVersion")
    compile("org.springframework.boot:spring-boot-starter-redis:$springRedisVersion")
    compile("org.springframework.data:spring-data-redis:$springDataRedis")
}

gradle.properties

#spring
springBootVersion=1.3.5.RELEASE
springRedisVersion=1.3.5.RELEASE
springDataRedis=1.7.2.RELEASE
springJunit=1.3.5.RELEASE
