spring boot Redis集成—RedisTemplate
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
前些天發現了一個巨牛的人工智能學習網站，通俗易懂，風趣幽默，忍不住分享一下給大家。點擊跳轉到教程。
Spring boot 基于Spring, ?Redis集成與Spring大同小異。
文章示例代碼均以前篇筆記為基礎增加修改，直接上代碼：
pom.xml ?Redis相關依賴：
?
[html]?view plain?copy
<?xml?version="1.0"?encoding="UTF-8"?>??<project?xmlns="http://maven.apache.org/POM/4.0.0"?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"??????xsi:schemaLocation="http://maven.apache.org/POM/4.0.0?http://maven.apache.org/xsd/maven-4.0.0.xsd">??????<modelVersion>4.0.0</modelVersion>??????<groupId>com.vic</groupId>??????<artifactId>vic</artifactId>??????<version>0.1.0</version>????????<properties>??????????<java.version>1.7</java.version>??????</properties>????????????<parent>??????????<groupId>org.springframework.boot</groupId>??????????<artifactId>spring-boot-starter-parent</artifactId>??????????<version>1.3.8.RELEASE</version>??????</parent>????????<dependencies>??????????<!--?spring?boot?-->??????????<dependency>??????????????<groupId>org.springframework.boot</groupId>??????????????<artifactId>spring-boot-starter-web</artifactId>??????????</dependency>????????????????????<!--?mybatis?-->??????????<dependency>??????????????<groupId>org.springframework.boot</groupId>??????????????<artifactId>spring-boot-starter-jdbc</artifactId>??????????</dependency>????????????<dependency>??????????????<groupId>org.mybatis</groupId>??????????????<artifactId>mybatis-spring</artifactId>??????????????<version>1.2.2</version>??????????</dependency>??????????<dependency>??????????????<groupId>org.mybatis</groupId>??????????????<artifactId>mybatis</artifactId>??????????????<version>3.2.8</version>??????????</dependency>????????????<dependency>??????????????<groupId>mysql</groupId>??????????????<artifactId>mysql-connector-java</artifactId>??????????</dependency>????????????<dependency>??????????????<groupId>com.mchange</groupId>??????????????<artifactId>c3p0</artifactId>??????????????<version>0.9.2.1</version>??????????</dependency>??????????????????????????????<!--?redis?-->??????????<dependency>??????????????<groupId>org.springframework.boot</groupId>??????????????<artifactId>spring-boot-starter-redis</artifactId>????????????</dependency>????????????????????<!--Gson-->????????????<dependency>????????????????<groupId>com.google.code.gson</groupId>????????????????<artifactId>gson</artifactId>????????????</dependency>????????????????????????????</dependencies>??????<build>??????????<plugins>??????????????<plugin>??????????????????<groupId>org.springframework.boot</groupId>??????????????????<artifactId>spring-boot-maven-plugin</artifactId>??????????????</plugin>??????????</plugins>??????</build>??</project>??

application.properties增加redis相關屬性：
?
?
[plain]?view plain?copy
#datasource??spring.datasource.jdbcUrl=jdbc:mysql://115.28.92.178:3306/wms?useUnicode\=true&characterEncoding\=utf8;autoReconnect\=true;maxReconnects\=10;connectTimeout\=180000;socketTimeout\=180000??spring.datasource.user=root??spring.datasource.password=xx??spring.datasource.driverClass=com.mysql.jdbc.Driver??spring.datasource.maxActive=100??spring.datasource.initialPoolSize=5??spring.datasource.minPoolSize=5??spring.datasource.maxPoolSize=20??spring.datasource.maxStatements=100??spring.datasource.maxIdleTime=3600??spring.datasource.acquireIncrement=2??spring.datasource.acquireRetryAttempts=10??spring.datasource.acquireRetryDelay=600??spring.datasource.testConnectionOnCheckin=true??spring.datasource.idleConnectionTestPeriod=1200??spring.datasource.checkoutTimeout=100000??????#redis??spring.redis.hostName=115.28.92.178??spring.redis.port=6379????spring.redis.password=xxx??spring.redis.pool.maxActive=8????spring.redis.pool.maxWait=-1????spring.redis.pool.maxIdle=8????spring.redis.pool.minIdle=0????spring.redis.timeout=0??

com.vic.config包中新增RedisConfig.java:
?
?
[java]?view plain?copy
/**??*???*?@author?vic??*?@desc?redis?config?bean??*??*/??@Configuration??@EnableAutoConfiguration??public?class?RedisConfig?{????????private?static?Logger?logger?=?Logger.getLogger(RedisConfig.class);????????????@Bean??????@ConfigurationProperties(prefix="spring.redis")??????public?JedisPoolConfig?getRedisConfig(){??????????JedisPoolConfig?config?=?new?JedisPoolConfig();??????????return?config;??????}????????????@Bean??????@ConfigurationProperties(prefix="spring.redis")??????public?JedisConnectionFactory?getConnectionFactory(){??????????JedisConnectionFactory?factory?=?new?JedisConnectionFactory();??????????JedisPoolConfig?config?=?getRedisConfig();??????????factory.setPoolConfig(config);??????????logger.info("JedisConnectionFactory?bean?init?success.");??????????return?factory;??????}??????????????????@Bean??????public?RedisTemplate<?,??>?getRedisTemplate(){??????????RedisTemplate<?,?>?template?=?new?StringRedisTemplate(getConnectionFactory());??????????return?template;??????}??}??
?

OK,此時Reddis已經集成完成，下面來對常用操作做一些封裝測試：
新增IRedisService接口定義一些常用操作接口，以及添加實現類RedisServiceImpl，代碼如下：
?
IRedisService.java
?
[java]?view plain?copy
/**??*???*?@author?vic??*?@desc?redis?service??*/??public?interface?IRedisService?{????????????public?boolean?set(String?key,?String?value);????????????public?String?get(String?key);????????????public?boolean?expire(String?key,long?expire);????????????public?<T>?boolean?setList(String?key?,List<T>?list);????????????public?<T>?List<T>?getList(String?key,Class<T>?clz);????????????public?long?lpush(String?key,Object?obj);????????????public?long?rpush(String?key,Object?obj);????????????public?String?lpop(String?key);????????}??
RedisServiceImpl.java
?
?
[java]?view plain?copy
/**??*???*?@author?vic??*?@desc?resdis?service??*??*/??@Service??public?class?RedisServiceImpl?implements?IRedisService{????????@Autowired??????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;??????}????????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?<T>?boolean?setList(String?key,?List<T>?list)?{??????????String?value?=?JSONUtil.toJson(list);??????????return?set(key,value);??????}????????@Override??????public?<T>?List<T>?getList(String?key,Class<T>?clz)?{??????????String?json?=?get(key);??????????if(json!=null){??????????????List<T>?list?=?JSONUtil.toList(json,?clz);??????????????return?list;??????????}??????????return?null;??????}????????@Override??????public?long?lpush(final?String?key,?Object?obj)?{??????????final?String?value?=?JSONUtil.toJson(obj);??????????long?result?=?redisTemplate.execute(new?RedisCallback<Long>()?{??????????????@Override??????????????public?Long?doInRedis(RedisConnection?connection)?throws?DataAccessException?{??????????????????RedisSerializer<String>?serializer?=?redisTemplate.getStringSerializer();??????????????????long?count?=?connection.lPush(serializer.serialize(key),?serializer.serialize(value));??????????????????return?count;??????????????}??????????});??????????return?result;??????}????????@Override??????public?long?rpush(final?String?key,?Object?obj)?{??????????final?String?value?=?JSONUtil.toJson(obj);??????????long?result?=?redisTemplate.execute(new?RedisCallback<Long>()?{??????????????@Override??????????????public?Long?doInRedis(RedisConnection?connection)?throws?DataAccessException?{??????????????????RedisSerializer<String>?serializer?=?redisTemplate.getStringSerializer();??????????????????long?count?=?connection.rPush(serializer.serialize(key),?serializer.serialize(value));??????????????????return?count;??????????????}??????????});??????????return?result;??????}????????@Override??????public?String?lpop(final?String?key)?{??????????String?result?=?redisTemplate.execute(new?RedisCallback<String>()?{??????????????@Override??????????????public?String?doInRedis(RedisConnection?connection)?throws?DataAccessException?{??????????????????RedisSerializer<String>?serializer?=?redisTemplate.getStringSerializer();??????????????????byte[]?res?=??connection.lPop(serializer.serialize(key));??????????????????return?serializer.deserialize(res);??????????????}??????????});??????????return?result;??????}????}??
其中的JSONUtil類，可下載demo代碼查看，其實就是一個JSON的工具類。
?
?
在ExampleController中添加測試方法：
?
[java]?view plain?copy
@RestController??public?class?ExampleController?{????????@Autowired??????private?IUserService?userService;????????????@Autowired??????private?IRedisService?redisService;????????????@RequestMapping("/users")??????public?ResponseModal?users(){??????????List<User>?users?=?userService.getAll();??????????ResponseModal?modal?=?new?ResponseModal(200,true,"",users);??????????return?modal;??????}????????????@RequestMapping("/redis/set")??????public?ResponseModal?redisSet(@RequestParam("value")String?value){??????????boolean?isOk?=?redisService.set("name",?value);??????????return?new?ResponseModal(isOk???200?:?500,?isOk,?isOk???"success"?:?"error"?,?null);??????}????????????@RequestMapping("/redis/get")??????public?ResponseModal?redisGet(){??????????String?name?=?redisService.get("name");??????????return?new?ResponseModal(200,?true,"success",name);??????}????????}??
?
?
?
?
?
運行Application的main函數
瀏覽器輸入：http://localhost:8080/redis/set?value=vic ?響應結果：
?
{"code":200,"success":true,"message":"success","response":null}
?
瀏覽器輸入：http://localhost:8080/redis/get ?響應結果：
?
{"code":200,"success":true,"message":"success","response":"vic"}
