本文介绍了解决Spring框架中redisTemplate注入失败的问题，并通过使用@Resource注解配合@Lazy注解实现了成功部署。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

首先先下载redis相关的jar包：

<!-- Redis客户端 -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

<!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-redis -->
<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：

<!-- 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>

<!-- redis单节点数据库连接配置 -->
<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="password" value="${redis.pass}" /> -->
    <property name="poolConfig" ref="jedisPoolConfig" />
</bean>

<!-- redisTemplate配置，redisTemplate是对Jedis的对redis操作的扩展，有更多的操作，封装使操作更便捷 -->
<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：

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
