异常问题记录 redis java dubbo

启动dubbo端服务器报错:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'jedisPool' defined in file [D:\gaoji\workspace\ego-soa\ego-rpc\ego-rpc-service-impl\target\classes\com\ego\config\spring\applicationContext-jedis.xml]: Unsatisfied
dependency expressed through constructor parameter 0: Could not convert argument value of type [java.lang.String] to required type [org.apache.commons.pool2.impl.GenericObjectPoolConfig]: Failed to convert value of type 'java.lang.String' to required type
'org.apache.commons.pool2.impl.GenericObjectPoolConfig'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'org.apache.commons.pool2.impl.GenericObjectPoolConfig': no matching editors or conversion
strategy found

错误分析:根据报错是我的 applicationContext-jedis配置文件的问题.好吧,单独把配置文件拎出来看,根据错误提示找到id="jedisPool" bean对象,发现把手残把ref写成了value,导致以上报错.红色标记处修改为ref,启动正常.

常见报错第2弹:

dubbo启动报错信息:noserializableexception或runtimeexception[13 xxxx]

原因分析:使用dubbo的时候,对象的参数或者返回值没有实现serializable接口,

解决方案:对dubbo中的方法的参数及返回值如果是自定义对象类型,实现serializable接口即可
