二、异常信息分析


通过打印的异常,可以确定三个问题:


1.找不到com.sku.common.model.JavaMerchant这个类(JavaMerchant是其他项目中的实体类),说明我们项目读取到了其他项目(SKU项目路)存储的数据



Caused by: com.fasterxml.jackson.databind.exc.InvalidTypeIdException: Could not resolve type id 'com.sku.common.model.JavaMerchant' as a subtype of [simple type, class java.lang.Object]: no such class found



2.涉及到redisson,说明和redis相关



ERROR org.redisson.client.handler.CommandDecoder - Unable to decode data. channel



3.涉及到tomcat,说明和容器有关



at org.apache.tomcat.util.net.SocketProcessorBase.



三、解决方案


通过上面的分支,定位到了项目SKU,发现该项目使用了HttpSession存值数据。



httpRequest.getSession().setAttribute("merchant", JSONObject.parseObject(JSON.toJSONString(apiResponse.getData()), JavaMerchant.class));



并且该项目和我们项目连的redis是一个,datebase也是同一个。然后通过看代码,发现我们项目引入了spring-session,也就是session共享,Session().setAttribute存储的数据,将存储到redis,并且其他项目也能访问到



   

           org.springframework.session
           spring-session-data-redis
       



所以解决办法就是


项目中不要使用httpRequest.getSession().setAttribute存储数据
