spring-boot-starter-data-redis学习笔记01

1.Redis在Unbuntu14开启，

进入安装的src目录：

1.修改redis.conf，因为redis默认是受保护模式。

protected-mode yes   （改为no）

bind 127.0.0.1    （注释掉，因为默认只有本机能访问）

requiredpass "password"  (新增一行，作为权限验证密码)

接下来开启redis,(这里一定要指定conf文件，默认不会使用你修改的redis.conf文件,导致修改内容无效)

nohup ./redis-server ../redis.conf  &

2.用./redis-cli 打开cli

127.0.0.1:6379>auth password

OK

127.0.0.1:6379>ping

PONG

验证通过

2.搭建SpringBoot-Redis环境

1.新建项目，pom.xml文件：

 　　<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 </dependencies>

　　2.application.properties配置

 核心只需配：

spring.redis.port=6379
spring.redis.host=xxx
spring.redis.password=password

编写controller方法

 @Autowired
    private StringRedisTemplate stringRedisTemplate;

    @GetMapping("set")
    public void setString() {
        stringRedisTemplate.opsForValue().set("lisi", "美女");
    }

    @GetMapping("show")
    public String getString() {
        return stringRedisTemplate.opsForValue().get("lisi");
    }

启动

@SpringBootApplication
public class SpringDataRedis01Application {

    public static void main(String[] args) {
        SpringApplication.run(SpringDataRedis01Application.class, args);
    }
}

　

StringRedisTemplate是继承自RedisTemplate，提供的一种对Key,Value为String类型的一种便利的操作对象
官方文档（Since it’s quite common for the keys and values stored in Redis to be java.lang.String, the Redis modules provides two extensions to RedisConnection
 and RedisTemplate, respectively the StringRedisConnection (and its DefaultStringRedisConnection implementation) and StringRedisTemplate as a convenient one-stop
 solution for intensive String operations. In addition to being bound to String keys, the template and the connection use the StringRedisSerializerunderneath
 which means the stored keys and values are human readable (assuming the same encoding is used both in Redis and your code)）

public class StringRedisTemplate extends RedisTemplate<String, String> {

    /**
     * Constructs a new <code>StringRedisTemplate</code> instance. {@link #setConnectionFactory(RedisConnectionFactory)}
     * and {@link #afterPropertiesSet()} still need to be called.
     */
    public StringRedisTemplate() {
        RedisSerializer<String> stringSerializer = new StringRedisSerializer();
        setKeySerializer(stringSerializer);
        setValueSerializer(stringSerializer);
        setHashKeySerializer(stringSerializer);
        setHashValueSerializer(stringSerializer);
    }
。。。。。。
}
