springboot 中 集成druid ，redis

1，导入druid jar包

<!--引入drud-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.</version>
        </dependency>

2，配置文件

#datasource
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.druid.driverClassName=com.mysql.jdbc.Driver
spring.datasource.druid.url=jdbc:mysql:///xxxxxx?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
spring.datasource.druid.username=root
spring.datasource.druid.password=xxxxx
spring.datasource.druid.initialSize=5
spring.datasource.druid.minIdle=5
spring.datasource.druid.maxActive=20
spring.datasource.druid.maxWait=60000
spring.datasource.druid.timeBetweenEvictionRunsMillis=60000
spring.datasource.druid.min-evictableIdleTimeMillis=300000
spring.datasource.druid.validationQuery=SELECT 1 FROM DUAL
spring.datasource.druid.testWhileIdle=true
spring.datasource.druid.testOnBorrow=false
spring.datasource.druid.testOnReturn=false
spring.datasource.druid.poolPreparedStatements=true
spring.datasource.druid.maxPoolPreparedStatementPerConnectionSize=20
spring.datasource.druid.filters=stat,wall
## druid 过滤
spring.datasource.druid.web-stat-filter.enabled=true
spring.datasource.druid.web-stat-filter.url-pattern=/*
spring.datasource.druid.web-stat-filter.exclusions=*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*
## druid 监控
spring.datasource.druid.stat-view-servlet.enabled=true
spring.datasource.druid.stat-view-servlet.url-pattern=/druid/*
spring.datasource.druid.stat-view-servlet.login-username=druid
spring.datasource.druid.stat-view-servlet.login-password=xxxxxx

　　3，配置redis

 @Value("${redis.hostName}")
    private String host;

    @Value("${redis.port}")
    private Integer port;

    @Value("${redis.password}")
    private String password;

    @Value("${redis.timeout}")
    private Integer timeout;

    @Value("${redis.maxIdle}")
    private Integer maxIdle;

    @Value("${redis.maxTotal}")
    private Integer maxTotal;

    @Value("${redis.maxWaitMillis}")
    private Integer maxWaitMillis;

    @Value("${redis.minEvictableIdleTimeMillis}")
    private Integer minEvictableIdleTimeMillis;

    @Value("${redis.numTestsPerEvictionRun}")
    private Integer numTestsPerEvictionRun;

    @Value("${redis.timeBetweenEvictionRunsMillis}")
    private long timeBetweenEvictionRunsMillis;

    @Value("${redis.testOnBorrow}")
    private boolean testOnBorrow;

    @Value("${redis.testWhileIdle}")
    private boolean testWhileIdle;

    @Bean
    public RedisTemplate redisTemplate(){

        JedisPoolConfig poolConfig = new JedisPoolConfig();

        //最大空闲
        poolConfig.setMaxIdle(maxIdle);

        //最大连接
        poolConfig.setMaxTotal(maxTotal);

        //最大等待时间
        poolConfig.setMaxWaitMillis(maxWaitMillis);

        //创建Jedis 连接工厂
        JedisConnectionFactory connectionFactory = new JedisConnectionFactory(poolConfig);

        connectionFactory.setHostName(host);
        connectionFactory.setPort(port);

        //调用后初始化方法，没有将抛出异常
        connectionFactory.afterPropertiesSet();

        //自定义Redis 序列化器
        RedisSerializer jdkSerializationRedisSerializer = new JdkSerializationRedisSerializer();
        RedisSerializer stringRedisSerializer = new StringRedisSerializer();

        //定义RedisTemplate
        RedisTemplate redisTemplate = new RedisTemplate();
         redisTemplate.setConnectionFactory(connectionFactory);

         //设置序列化器
        redisTemplate.setDefaultSerializer(stringRedisSerializer);
        redisTemplate.setKeySerializer(stringRedisSerializer);
        redisTemplate.setValueSerializer(jdkSerializationRedisSerializer);
        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        redisTemplate.setHashValueSerializer(jdkSerializationRedisSerializer);
        return redisTemplate;

    }

    @Bean(name="redisCacheManager")
    public CacheManager cacheManager(@Autowired RedisTemplate redisTemplate){
        RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);

        //设置超时时间,10分种
        cacheManager.setDefaultExpiration(600);
        List<String> cacheName = new ArrayList<>();
        cacheName.add("redisCacheManger");
        cacheManager.setCacheNames(cacheName);
        return cacheManager;
    }
