springboot 整合redis_springboot自动装配原理详解

<div>
<h2><b>1)传统ssm整合redis的时候需要在xml的配置文件中进行大量的配置Bean</b></h2>
<p> 我们在这里使用springboot来代替ssm的整合，只是通过xml的形式来整合redis</p>
<p><b>第一步:加入配置</b></p>
<div class="blockcode">
  <pre class="blockcode"><code><dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>2.0.9.RELEASE</version>
</dependency>

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency></code></pre>
</div>
<p><b>第二步: 配置xml的bean的配置</b></p>
<div class="blockcode">
  <pre class="blockcode"><code> //配置连接池
<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
      <property name="minIdle" value="10"></property>
      <property name="maxTotal" value="20"></property>
</bean>

//配置连接工厂
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
      <property name="hostName" value="47.104.128.12"></property>
      <property name="password" value="123456"></property>
      <property name="database" value="0"></property>
      <property name="poolConfig" ref="poolConfig"></property>
</bean>

//配置 redisTemplate 模版类
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
      <property name="connectionFactory"  ref="jedisConnectionFactory"/>
      
      <property name="keySerializer">
         <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
      </property>
      <property name="valueSerializer">
         <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/>
      </property>
      <property name="hashKeySerializer">
         <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
      </property>
      <property name="hashValueSerializer">
      <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/>
      </property>
</bean></code></pre>
</div>
<p><b>第三步:导入配置</b></p>
<p><b>@ImportResource(locations = "classpath:beans.xml") 可以导入xml的配置文件</b></p>
<div class="blockcode">
  <pre class="blockcode"><code>@SpringBootApplication
@ImportResource(locations = "classpath:beans.xml")
@RestController
public class TulingOpenAutoconfigPrincipleApplication {

@Autowired
private RedisTemplate redisTemplate;

public static void main(String[] args) {
  SpringApplication.run(TulingOpenAutoconfigPrincipleApplication.class, args);
}

@RequestMapping("/testRedis")
public String testRedis() {
  redisTemplate.opsForValue().set("smlz","smlz");
  return "OK";
}
}</code></pre>
</div>
<p><b>2)综上所述我们发现，若整合redis的时候通过传统的整合，进行了大量的配置,那么我们来看下通过springboot自动装配整合的对比</b></p>
<p><b>导入依赖:</b></p>
<div class="blockcode">
  <pre class="blockcode"><code>  <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
  </dependency></code></pre>
</div>
<p><b>修改yml配置文件</b></p>
<div class="blockcode">
  <pre class="blockcode"><code>spring.redis.host=47.104.128.12
spring.redis.port=6379
spring.redis.password=123456</code></pre>
</div>
<p><b>直接使用(下述代码可以不要配置，为了解决保存使用jdk的序列方式才配置的)</b></p>
<div class="blockcode">
  <pre class="blockcode"><code> @Bean
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)  {
  RedisTemplate<Object, Object> template = new RedisTemplate<>();
  template.setDefaultSerializer(new Jackson2JsonRedisSerializer<Object>(Object.class));
  template.setConnectionFactory(redisConnectionFactory);
  return template;
}</code></pre>
</div>
<p><b>3）传统整合和springboot自动装配优劣势分析。。。。。。。。。。。。</b></p>
<p><b>4）自动装配原理前的不得不说的几个注解</b></p>
<p><b>4.1)通过@Import注解来导入ImportSelector组件</b></p>
<p><b>①:写一个配置类在配置类上标注一个@Import的注解，</b></p>
<div class="blockcode">
  <pre class="blockcode"><code>@Configuration
@Import(value = {Tuling
