观察报错原因 为 :
Failed to convert property value of type [java.lang.String] to required type [int] for property 'maxIdle'; nested exception is java.lang.NumberFormatException: For input string: "${redis.maxIdle}"
未能将java.lang.string类型的文件转换成maxIdle属性需要的int类型 为数据转换类型错误
仔细分析后:
原来是在测试时,没有导入redis.properties文件,value把${redis.maxIdle}解析为字符串,所以会报: For input string: "${redis.maxIdle}"异常。实际在项目部署启动tomcat后就不会报这样的异常,因为不会获取不到配置文件。
更改方法:
在spring配置文件目录下apllicationContext-redis中添加
<context:property-placeholder location="classpath*:properties/*.properties" />
修改后的application-redis.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="JedisConnectionFactory" />
</bean>
</beans>
修改完成后,项目正常运行。
