Spring Redis - 从 application.properties 文件读取配置 [英] Spring Redis - Read configuration from application.properties file

问题描述

我让 Spring Redis 使用 spring-data-redis 和所有默认配置工作，比如 localhost 默认 port 等等.

I have Spring Redis working using spring-data-redis with all default configuration likes localhost default port and so on.

现在我试图通过在 application.properties 文件中进行配置来进行相同的配置.但是我不知道我应该如何准确创建读取我的属性值的 bean.

Now I am trying to make the same configuration by configuring it in application.properties file. But I cannot figure out how should I create beans exactly that my property values are read.

Redis 配置文件

@EnableRedisHttpSession
@Configuration
public class SpringSessionRedisConfiguration {

@Bean
JedisConnectionFactory connectionFactory() {
    return new JedisConnectionFactory();
}

@Autowired
@Bean
RedisCacheManager redisCacheManager(final StringRedisTemplate stringRedisTemplate) {
    return new RedisCacheManager(stringRedisTemplate);
}

@Autowired
@Bean
StringRedisTemplate template(final RedisConnectionFactory connectionFactory) {
    return new StringRedisTemplate(connectionFactory);
}
}

application.properties 中的标准参数

Standard Parameters in application.properties

spring.redis.sentinel.master=themaster

spring.redis.sentinel.master=themaster

spring.redis.sentinel.nodes=192.168.188.231:26379

spring.redis.sentinel.nodes=192.168.188.231:26379

spring.redis.password=12345

spring.redis.password=12345

我试过的，

1. 我可以使用 @PropertySource 然后注入 @Value 并获取值.但我不想这样做，因为这些属性不是我定义的，而是来自 Spring.
2. 在本文档中 Spring Redis 文档，它只说可以使用属性进行配置，但没有显示具体示例.
3. 我还浏览了 Spring Data Redis API 类，发现 RedisProperties 应该对我有帮助，但仍然无法弄清楚如何告诉 Spring 从属性文件中读取数据.

1. I can possibly use @PropertySource and then inject @Value and get the values. But I don't want to do that as those properties are not defined by me but are from Spring.
2. In this documentation Spring Redis Documentation, it only says that it can be configured using properties but doesn't show concrete example.
3. I also went through Spring Data Redis API classes, and found that RedisProperties should help me, but still cannot figure out how exactly to tell Spring to read from properties file.

推荐答案

您可以使用 @PropertySource 从 application.properties 或您想要的其他属性文件中读取选项.请查看 PropertySource 使用示例 并使用 使用示例 spring-redis-cache.或者看看这个小样本:

You can use @PropertySource to read options from application.properties or other property file you want. Please look PropertySource usage example and working example of usage spring-redis-cache. Or look at this small sample:

@Configuration
@PropertySource("application.properties")
public class SpringSessionRedisConfiguration {

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

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

    @Bean
    public static PropertySourcesPlaceholderConfigurer    propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean
    JedisConnectionFactory jedisConnectionFactory() {
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setHostName(redisHostName);
        factory.setPort(redisPort);
        factory.setUsePool(true);
        return factory;
    }

    @Bean
    RedisTemplate<Object, Object> redisTemplate() {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
        redisTemplate.setConnectionFactory(jedisConnectionFactory());
        return redisTemplate;
    }

    @Bean
    RedisCacheManager cacheManager() {
        RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate());
        return redisCacheManager;
    }
}

目前(2015 年 12 月)application.properties 中的 spring.redis.sentinel 选项对 RedisSentinelConfiguration 的支持有限:

In present time (december 2015) the spring.redis.sentinel options in application.properties has limited support of RedisSentinelConfiguration:

请注意，目前只有 Jedis 和生菜 Lettuce 支持Redis Sentinel.

Please note that currently only Jedis and lettuce Lettuce support Redis Sentinel.
