SpringBoot整合Redis入门HelloWorld及配置序列化器_spring boot 整合redisearch

1、Redis安装

Redis安装教程

2、环境搭建

创建SpringBoot项目

导入依赖

<dependencies>
    <!--redis-->
    <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>

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.junit.vintage</groupId>
                <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
</dependencies>

配置配置文件

可参考上图配置

使用SpringBoot配置好的StringRedisTemplate来操作redis

---

3、基本测试

@Test
    void contextLoads() {
        stringRedisTemplate.opsForValue().set("hello","world");

        String hello = stringRedisTemplate.opsForValue().get("hello");

        System.out.println("键hello对应的数据是："+hello);
}

4、向redis中以JSON格式存入Java实体类（配置序列化器）

创建实体类

注意实现Serializable 接口

public class User implements Serializable {
    private String name;
    private Integer age;
    private String address;

    @Override
    public String toString() {
        return "User{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", address='" + address + '\'' +
                '}';
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

1、如果使用RedisTemplate

但是redis存储的是一堆乱码

需要配置在配置类中设置序列化器

@Configuration
public class MyRedisConfig {

    @Bean(name="redisTemplate")
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, String> template = new RedisTemplate<>();
        RedisSerializer<String> redisSerializer = new StringRedisSerializer();
        template.setConnectionFactory(factory);
        //key序列化方式
        template.setKeySerializer(redisSerializer);
        //value序列化
        template.setValueSerializer(redisSerializer);
        //value hashmap序列化
        template.setHashValueSerializer(redisSerializer);
        //key haspmap序列化
        template.setHashKeySerializer(redisSerializer);
        //
        return template;
    }
}

2、如果使用StringRedisTemplate

可使用JSON工具进行转化

@Test
    void contextLoads() {
        User user = new User();
        user.setName("小明");
        user.setAge(17);
        user.setAddress("学校");
		//JSON工具进行转化
        String s = JSONValue.toJSONString(user);
        redisTemplate.opsForValue().set("data",s);

        Object hello = redisTemplate.opsForValue().get("data");

        System.out.println("键hello对应的数据是："+hello.toString());
    }
