SpringBoot实战（四）:SpringBoot整合Redis

强烈推荐一个大神的人工智能的教程：http://www.captainai.net/zhanghan

【前言】

最近自己在整理过去搭建过的框架，将用到的各个组件进行了梳理并融入自己新建的项目中（https://github.com/dangnianchuntian/springboot），一是对过去项目的整理；二是在整理的过程中查漏补缺；三是以后可以拿过去就用；

【整合Redis实战】

一、Pom中引入相应的Jar包

<!-- redis -->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId>
</dependency><dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.9.0</version>
</dependency>

二、重要代码展示

1、读取配置文件中配置连接Redis属性值

package com.zhanghan.zhboot.properties;import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;@Component
@Data
@ConfigurationProperties
public class RedisProperties {@Value("${spring.redis.database}")private int database;@Value("${spring.redis.host}")private String host;@Value("${spring.redis.port}")private int port;@Value("${spring.redis.password}")private String password;@Value("${spring.redis.pool.max-idle}")private int maxIdle;@Value("${spring.redis.pool.min-idle}")private int minIdle;@Value("${spring.redis.pool.max-active}")private int maxActive;@Value("${spring.redis.pool.max-wait}")private int maxWait;@Value("${spring.redis.timeout}")private int timeout;}

2、创建相应的Redis操作template

package com.zhanghan.zhboot.config;import com.zhanghan.zhboot.properties.RedisProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;
import org.springframework.data.redis.connection.RedisPassword;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.jedis.JedisClientConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericToStringSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {@Autowiredprivate RedisProperties redisProperties;@Beanpublic JedisConnectionFactory jedisConnectionFactory() {RedisStandaloneConfiguration rf = new RedisStandaloneConfiguration();rf.setDatabase(redisProperties.getDatabase());rf.setHostName(redisProperties.getHost());rf.setPort(redisProperties.getPort());rf.setPassword(RedisPassword.of(redisProperties.getPassword()));JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jpb =(JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder();JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();jedisPoolConfig.setMaxIdle(redisProperties.getMaxIdle());jedisPoolConfig.setMinIdle(redisProperties.getMinIdle());jedisPoolConfig.setMaxTotal(redisProperties.getMaxActive());jedisPoolConfig.setMaxWaitMillis(redisProperties.getMaxWait());jedisPoolConfig.setEvictorShutdownTimeoutMillis(redisProperties.getTimeout());jpb.poolConfig(jedisPoolConfig);JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(rf, jpb.build());return jedisConnectionFactory;}@Beanpublic static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {return new PropertySourcesPlaceholderConfigurer();}@BeanRedisTemplate<Object, Object> redisTemplate() {RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();redisTemplate.setConnectionFactory(jedisConnectionFactory());return redisTemplate;}@BeanRedisTemplate<String, String> strRedisTemplate() {final RedisTemplate<String, String> template = new RedisTemplate<>();template.setConnectionFactory(jedisConnectionFactory());template.setKeySerializer(new StringRedisSerializer());template.setHashValueSerializer(new GenericToStringSerializer<>(String.class));template.setValueSerializer(new GenericToStringSerializer<>(String.class));return template;}@BeanRedisTemplate<String, Long> longRedisTemplate() {final RedisTemplate<String, Long> template = new RedisTemplate<>();template.setConnectionFactory(jedisConnectionFactory());template.setKeySerializer(new StringRedisSerializer());template.setHashValueSerializer(new GenericToStringSerializer<>(Long.class));template.setValueSerializer(new GenericToStringSerializer<>(Long.class));return template;}@BeanRedisTemplate<String, Boolean> booleanRedisTemplate() {final RedisTemplate<String, Boolean> template = new RedisTemplate<>();template.setConnectionFactory(jedisConnectionFactory());template.setKeySerializer(new StringRedisSerializer());template.setHashValueSerializer(new GenericToStringSerializer<>(Boolean.class));template.setValueSerializer(new GenericToStringSerializer<>(Boolean.class));return template;}
}

3、使用相应的RedisTemplate演示

package com.zhanghan.zhboot.controller;import com.mysql.jdbc.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.util.ObjectUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;import java.util.HashMap;
import java.util.Map;@RestController
public class RedisController {@Autowiredprivate RedisTemplate<String, String> strRedisTemplate;@Autowiredprivate RedisTemplate<String, Long> longRedisTemplate;@Autowiredprivate RedisTemplate<String, Boolean> booleanRedisTemplate;@RequestMapping(value = "/get/redis", method = RequestMethod.GET)public Map xmlAnalysis() {String strRedisKey = "zh:boot:String";String longRedisKey = "zh:boot:long";String booleanRedisKey = "zh:boot:bollean";String strRedisValue = strRedisTemplate.opsForValue().get(strRedisKey);if (StringUtils.isNullOrEmpty(strRedisValue)) {strRedisTemplate.opsForValue().set(strRedisKey, "张晗");}Long longRedisValue = longRedisTemplate.opsForValue().get(longRedisKey);if (ObjectUtils.isEmpty(longRedisValue)) {longRedisTemplate.opsForValue().set(longRedisKey, 1L);}Boolean booleanRedisValue = booleanRedisTemplate.opsForValue().get(booleanRedisKey);if (ObjectUtils.isEmpty(booleanRedisValue)) {booleanRedisTemplate.opsForValue().set(booleanRedisKey, true);}strRedisValue = strRedisTemplate.opsForValue().get(strRedisKey);longRedisValue = longRedisTemplate.opsForValue().get(longRedisKey);booleanRedisValue = booleanRedisTemplate.opsForValue().get(booleanRedisKey);Map result = new HashMap();result.put(strRedisKey, strRedisValue);result.put(longRedisKey, longRedisValue);result.put(booleanRedisKey, booleanRedisValue);return result;}}

三、效果展示

四、项目地址及代码版本

1、地址：https://github.com/dangnianchuntian/springboot

2、代码版本：1.0.0-Release

【总结】

1、总结，提炼，查漏补缺；

2、要有前瞻性。
