根据标红的错误信息可以看出来：

在itemCatService中Injection of autowired dependencies failed; 依赖注入失败

为什么会依赖注入失败呢？

从最后一个报错日志来看，问题可能发生在redis.core.RedisTemplate上。

经过同学的指导发现我的pom文件依赖引入错误。

在另一个模块的applicationContext_redis.xml中，已经对redisTemplate进行了注入

 <bean id="JedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
        p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:pool-config-ref="poolConfig"/>

 <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
       <property name="connectionFactory" ref="JedisConnectionFactory" />
 bean>

而我在这个模块引入的依赖，在这个模块的applicationContext_service.xml中并没有对redisTemplate进行注入，所以提示我注入失败。

<dependency>
   <groupId>org.springframework.datagroupId>
   <artifactId>spring-data-redisartifactId>
dependency>

<dubbo:protocol name="dubbo" port="20881">dubbo:protocol>

<dubbo:application name="ylx_service_sellergoods"/>
<dubbo:registry address="zookeeper://192.168.182.135:2181"/>
<dubbo:annotation package="com.youlexuan.sellergoods.service" />

最后在pom文件中把spring-data-redis改成了另一个模块的依赖，这样就可以注入成功。或者在applicationContext_service.xml中对redisTemplate进行注入也可以。
