springboot中redis相关配置1、pom.xml中引入依赖 <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> 2、springboot的习惯优于配置。也在项目中使用了application.yml文件配置mysql的基本配置项。这里也在application.yml里面配置redis的配置项。 spring: datasource: # 驱动配置信息 url: jdbc:mysql://localhost:3306/spring_boot?useUnicode=true&characterEncoding=utf8 username: root password: root type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver # 连接池的配置信息 filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20 redis: host: 127.0.0.1 port: 6379 password: pass1234 pool: max-active: 100 max-idle: 10 max-wait: 100000 timeout: 0 springboot中redis相关类
redis单独放在一个包redis里,在包里先创建RedisConfig.java文件。 RedisConfig.java @Configuration @EnableAutoConfiguration public class RedisConfig { @Bean @ConfigurationProperties(prefix = "spring.redis.pool") public JedisPoolConfig getRedisConfig(){ JedisPoolConfig config = new JedisPoolConfig(); return config; } @Bean @ConfigurationProperties(prefix = "spring.redis") public JedisConnectionFactory getConnectionFactory() { JedisConnectionFactory factory = new JedisConnectionFactory(); factory.setUsePool(true); JedisPoolConfig config = getRedisConfig(); factory.setPoolConfig(config); return factory; } @Bean public RedisTemplate<?, ?> getRedisTemplate() { JedisConnectionFactory factory = getConnectionFactory(); RedisTemplate<?, ?> template = new StringRedisTemplate(factory); return template; } }
RedisServiceImpl.java @Service("redisService") public class RedisServiceImpl implements RedisService { @Resource private RedisTemplate<String, ?> redisTemplate; @Override public boolean set(final String key, final String value) { boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { @Override public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = redisTemplate.getStringSerializer(); connection.set(serializer.serialize(key), serializer.serialize(value)); return true; } }); return result; } @Override public String get(final String key) { String result = redisTemplate.execute(new RedisCallback<String>() { @Override public String doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = redisTemplate.getStringSerializer(); byte[] value = connection.get(serializer.serialize(key)); return serializer.deserialize(value); } }); return result; } @Override public boolean expire(final String key, long expire) { return redisTemplate.expire(key, expire, TimeUnit.SECONDS); } @Override public boolean remove(final String key) { boolean result = redisTemplate.execute(new RedisCallback<Boolean>() { @Override public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer<String> serializer = redisTemplate.getStringSerializer(); connection.del(key.getBytes()); return true; } }); return result; } } 在这里execute()方法具体的底层没有去研究,只知道这样能实现对于redis数据的操作。 到此,redis在springboot中的整合已经完毕,下面就来测试使用一下。 5. springboot项目中使用redis在这里就直接使用springboot项目中自带的单元测试类SpringbootApplicationTests进行测试。 @RunWith(SpringRunner.class) @SpringBootTest public class SpringbootApplicationTests { private JSONObject json = new JSONObject(); @Autowired private RedisService redisService; @Test public void contextLoads() throws Exception { } /** * 插入字符串 */ @Test public void setString() { redisService.set("redis_string_test", "springboot redis test"); } /** * 获取字符串 */ @Test public void getString() { String result = redisService.get("redis_string_test"); System.out.println(result); } /** * 插入对象 */ @Test public void setObject() { Person person = new Person("person", "male"); redisService.set("redis_obj_test", json.toJSONString(person)); } /** * 获取对象 */ @Test public void getObject() { String result = redisService.get("redis_obj_test"); Person person = json.parseObject(result, Person.class); System.out.println(json.toJSONString(person)); } /** * 插入对象List */ @Test public void setList() { Person person1 = new Person("person1", "male"); Person person2 = new Person("person2", "female"); Person person3 = new Person("person3", "male"); List<Person> list = new ArrayList<>(); list.add(person1); list.add(person2); list.add(person3); redisService.set("redis_list_test", json.toJSONString(list)); } /** * 获取list */ @Test public void getList() { String result = redisService.get("redis_list_test"); List<String> list = json.parseArray(result, String.class); System.out.println(list); } @Test public void remove() { redisService.remove("redis_test"); } } class Person { private String name; private String sex; public Person() { } public Person(String name, String sex) { this.name = name; this.sex = sex; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } } 在这里先是用@Autowired注解把redisService注入进来,然后由于是使用json字符串进行交互,所以引入fastjson的JSONObject类。然后为了方便,直接在这个测试类里面加了一个Person的内部类。 一共测试了:对于string类型的存取,对于object类型的存取,对于list类型的存取,其实本质都是转成了json字符串。还有就是根据key来执行remove操作。 获取字符串: 获取对象: 获取list: redis管理客户端数据: 到此,测试完成,对于常用的一些数据类型的转换存取操作也基本调试通过。所以本文对于springboot整合redis到此结束。 到此这篇关于Redis在项目中的使用(JedisPool方式)的文章就介绍到这了,更多相关Redis项目中使用内容请搜索极客世界以前的文章或继续浏览下面的相关文章希望大家以后多多支持极客世界! |
