这是具体错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jedisClientPool' defined in file [F:\eclipseUseful\fastssm\target\classes\spring\applicationContext-redis.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'jedisPool' of bean class [redis.clients.jedis.JedisPool]: Bean property 'jedisPool' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

其实就是bean没有被配置，spring无法注入对象。

看上面这个

jedisPool

找到配置文件这个bean id，查看

<bean id="jedisClientPool" class="com.fast.ssm.util.jedis.JedisClientPool">
    		<property name="jedisPool" ref="jedisPool"/>
    	</bean>

我这里是这样配置的

刚开始主要是配置文件class忘记了对应具体的class，所以找到JedisClientPool这个类，复制一下全限定名路径，粘贴就行了。

这样配置文件就可以找到具体的bean，并把它注入了。

**还有一种是**

这个name写的不对，spring里面有一种情况就是开始小写，后边遵循驼峰法的可以正常被管理，其他的会报错。
