springmvc集成redis遇到的问题

刺骨的言语ヽ痛彻心扉 2021-12-03 14:37 689阅读 0赞

首先先下载redis相关的jar包：

<dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>
    
    
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-redis</artifactId>
        <version>1.8.7.RELEASE</version>
    </dependency>

然后配置spring中的redis配置：

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="105" />
        <property name="maxIdle" value="10" />
        <property name="maxWaitMillis" value="5000" />
        <property name="testOnBorrow" value="true" />
    </bean>
    
    
    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="127.0.0.1" />
        <property name="port" value="6379" />
        
        <property name="poolConfig" ref="jedisPoolConfig" />
    </bean>
    
    
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="jedisConnectionFactory" />
    </bean>

然后我是在controller进行注入的，一直报错：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'redisTemplate' available

重点就是一直说redisTemplate找不到，但是也确实能够跳转到XML文件中，网上说是将

@Autowired注解改成@Resource(name = "redisTemplate")但是没有用然后，
    在@Resource(name = "redisTemplate")之上加了一个在注解@Lazy进行懒加载，然后就没有问题了
