• 配置pom 引入依赖

        <!-- 配置starter -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

        <!-- 配置jedis客户端，默认lettuce -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>

• yml配置Redis连接参数

spring:
  redis:
    #    url: redis://:123456@127.0.0.1:6379
    port: 6379
    host: 127.0.0.1
    username:
    password: 123456
    # 客户端类型 lettuce(默认) jedis
    client-type: jedis
    # jedis连接池配置
    jedis:
      pool:
        max-active: 10
    # lettuce连接池配置
    lettuce:
      pool:
        max-active: 10

• 案例：redis记录控制器访问次数
• 配置拦截器，用于记录每次请求的记录

// redis记录控制器访问拦截器
@Component
public class UrlRedisControllerInterceptor implements HandlerInterceptor {

    // 注入redis客户端模版
    @Autowired
    StringRedisTemplate redisTemplate;

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        // 获取请求路径
        String uri = request.getRequestURI();
        // 记录访问次数自增
        redisTemplate.opsForValue().increment(uri);
        // 一律放行
        return true;
    }
}

• 注册拦截器

// 自定义Spring配置
@Configuration
public class WebConfig implements WebMvcConfigurer {

    // 在容器中获取Auth拦截器
    @Autowired
    AuthInterceptor authInterceptor;

    // 在容器中获取Redis记录控制器访问拦截器
    @Autowired
    UrlRedisControllerInterceptor urlRedisControllerInterceptor;

    /**
     * 拦截器
     *
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // Auth拦截器
        registry.addInterceptor(authInterceptor)
                // 需要拦截路径
                .addPathPatterns("/**")
                // 排除的拦截路径
                .excludePathPatterns("/login", "/favicon.ico", "/image/**", "/js/**", "/css/**");

        // redis记录控制器访问拦截器
        registry.addInterceptor(urlRedisControllerInterceptor)
                // 需要拦截路径
                .addPathPatterns("/**")
                // 排除的拦截路径
                .excludePathPatterns("/login", "/favicon.ico", "/image/**", "/js/**", "/css/**");
    }
}

• 获取Redis数据

    @Autowired
    StringRedisTemplate stringRedisTemplate;

    @Test
    void redisTest() {
        ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
        String index_num = operations.get("/index");
        // index页面访问次数
        System.out.println(index_num);
    }
