springboot自学笔记-整合redis（二）

基于整合redis（一）的基础上，将连接池信息和redis连接信息整合到配置文件application.properties中。

整合redis的关键类：

package com.test.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import redis.clients.jedis.JedisPoolConfig;

@Configuration
public class RedisConfig {

    @Bean
    public JedisPoolConfig jedisPoolConfig() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        //最大空闲数量
        jedisPoolConfig.setMaxIdle(10);
        //最小空闲数量
        jedisPoolConfig.setMinIdle(5);
        //最大连接数量
        jedisPoolConfig.setMaxTotal(30);
        return jedisPoolConfig;
    }
    
    @Bean
    public JedisConnectionFactory jedisPoolConfig(JedisPoolConfig config) {
        JedisConnectionFactory JedisConnectionFactory = new JedisConnectionFactory();
        //关联连接池的配置对象
        JedisConnectionFactory.setPoolConfig(config);
        //配置连接redis的信息
        JedisConnectionFactory.setHostName("127.0.0.1");
        //端口号
        JedisConnectionFactory.setPort(6379);
        return JedisConnectionFactory;
    }
    
    @Bean
    public RedisTemplate<String, Object> redisTemplate(JedisConnectionFactory factory){
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(factory);//关联
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new StringRedisSerializer());
        return template;
    }
    
}

通过注解@ConfigurationProperties(prefix=""),提取完信息如下:

package com.test.config;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import redis.clients.jedis.JedisPoolConfig;

@Configuration
public class RedisConfig2 {

    @Bean
    @ConfigurationProperties(prefix="spring.redis.pool")
    public JedisPoolConfig jedisPoolConfig() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        return jedisPoolConfig;
    }
    
    @Bean
    @ConfigurationProperties(prefix="spring.redis")
    public JedisConnectionFactory jedisPoolConfig(JedisPoolConfig config) {
        JedisConnectionFactory JedisConnectionFactory = new JedisConnectionFactory();
        //关联连接池的配置对象
        JedisConnectionFactory.setPoolConfig(config);
        return JedisConnectionFactory;
    }
    
    @Bean
    public RedisTemplate<String, Object> redisTemplate(JedisConnectionFactory factory){
        RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(factory);//关联
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new StringRedisSerializer());
        return template;
    }
    
}

application.properties如下：

spring.redis.pool.max-idle=10
spring.redis.pool.min-idle=5
spring.redis.pool.max-total=30

spring.redis.hostName=127.0.0.1
spring.redis.port=6379
