redis:spring-data-redis

首先需要安装redis：
下载地址：https://github.com/MSOpenTech/redis/releases

完成后，开始写代码：
使用注解的方式进行配置

@Configuration@EnableWebMvc@ComponentScan(basePackages = {"xx.redis"})@PropertySource({"classpath:jedis.properties"}) public class ApplicationConfig extends WebMvcConfigurerAdapter {    @Override    public void addResourceHandlers(ResourceHandlerRegistry registry) {                    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");    }    @Override        public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {            configurer.enable();        }    @Autowired      private Environment env;    @Bean    public Gson gson(){        return new Gson();    }    @Bean    public JedisPoolConfig poolConfig(){        Integer maxIdle = getIntValueFromEnv("jedis.maxIdle");        Integer maxTotal = getIntValueFromEnv("jedis.maxTotal");        Long maxWaitMillis = getLongValueFromEnv("jedis.maxWaitMillis");        Boolean testOnBorrow = getBooleanValueFromEnv("jedis.testOnBorrow");        JedisPoolConfig jedisPoolConfig =  new JedisPoolConfig();        jedisPoolConfig.setMaxIdle(maxIdle == null ?

JedisPoolConfig.DEFAULT_MAX_TOTAL : maxTotal);        jedisPoolConfig.setMaxWaitMillis(maxWaitMillis == null ? JedisPoolConfig.DEFAULT_MAX_WAIT_MILLIS : maxWaitMillis);        jedisPoolConfig.setTestOnBorrow(testOnBorrow == null ? JedisPoolConfig.DEFAULT_TEST_ON_BORROW : testOnBorrow);        return jedisPoolConfig;    }    @Bean    public JedisConnectionFactory connectionFactory(){        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(poolConfig());        String hostName = getStringValueFromEnv("jedis.host");        System.out.println("hostName:"+hostName);        Integer port = getIntValueFromEnv("jedis.port");        String password = getStringValueFromEnv("jedis.password");        jedisConnectionFactory.setHostName(hostName);        if(port != null) jedisConnectionFactory.setPort(port);        if(port != null) jedisConnectionFactory.setPassword(password == null ? "" : password);        return jedisConnectionFactory;    }    @Bean    public StringRedisSerializer stringRedisSerializer(){        return new StringRedisSerializer();    }    @SuppressWarnings({ "rawtypes", "unchecked" })    @Bean    public RedisTemplate redisTemplate(){        RedisTemplate redisTemplate = new RedisTemplate<>();        redisTemplate.setConnectionFactory(connectionFactory());        redisTemplate.setKeySerializer(stringRedisSerializer());        redisTemplate.setEnableTransactionSupport(true);        return redisTemplate;    }    private String getStringValueFromEnv(String key) {        return env.getProperty(key) == null ? null : String.valueOf(env.getProperty(key));    }    private Long getLongValueFromEnv(String key) {        return env.getProperty(key) == null ? null : Long.valueOf(env.getProperty(key));    }    private Boolean getBooleanValueFromEnv(String key) {        return env.getProperty(key) == null ? null : Boolean.valueOf(env.getProperty(key));    }    public Integer getIntValueFromEnv(String key){        return env.getProperty(key) == null ? null : Integer.valueOf(env.getProperty(key));    }}

jedis.properties:

测试：

    @Override    public List<Teacher> listTeachers() {        String key = "allTeacherCache";        Long length = listOps.length(key);        if(length != 0){            List<String> teacherStringS = listOps.range(key, 0, Integer.valueOf(length.toString()));            return jsonsToTeachers(teacherStringS);        }        List<Teacher> teachers = getAllTeachers();        setTeachersCache(teachers, key);        return teachers;    }    private void setTeachersCache(List<Teacher> teachers, String key) {        teachers.stream().forEach(teacher->listOps.push(key, seriazileUtil.seriazileAsString(teacher)));    }    private List<Teacher> jsonsToTeachers(List<String> json){        return json.stream().map(teacherStr->{            return seriazileUtil.deserializeAsObject(teacherStr, Teacher.class);        }).collect(Collectors.toList());    }
