使用SpringBoot cache+redis遇到的一個(gè)奇怪報(bào)錯(cuò).
而且并不是一開(kāi)始出現(xiàn)的，是在測(cè)試過(guò)程中，偶然出現(xiàn)的一個(gè)報(bào)錯(cuò)。
錯(cuò)誤提示是類型轉(zhuǎn)換異常, 自己不能轉(zhuǎn)換成為自己。

以為是實(shí)體類序列化問(wèn)題，有實(shí)現(xiàn)Serializable接口，并重新生成id，無(wú)效
由于項(xiàng)目使用了fastjson，redis cache序列化使用了Jackson2JsonRedisSerializer。一頓百度改為使用fastJson作為序列化和反序列化，無(wú)效。
排查pom.xml 但由于這問(wèn)題是中途出現(xiàn)，且偶爾出現(xiàn)。。。放棄排查pom.xml

偶然想起項(xiàng)目中用到了spring-boot-devtools, 嘗試從parent的pom.xml中注釋掉,報(bào)錯(cuò)消失。

        <!-- devtools,熱部署插件 -->
         <!-- <dependency>

忍不住上官網(wǎng)查了一下這個(gè)插件。官方里描述的部分內(nèi)容。

As described earlier in the Restart vs Reload section, restart functionality is implemented by using two classloaders. For most applications, this approach works well. However, it can sometimes cause classloading issues.

Known Limitations
Restart functionality does not work well with objects that are deserialized by using a standard ObjectInputStream. If you need to deserialize data, you may need to use Spring’s ConfigurableObjectInputStream in combination with Thread.currentThread().getContextClassLoader().
Unfortunately, several third-party libraries deserialize without considering the context classloader. If you find such a problem, you need to request a fix with the original authors.

個(gè)人大概理解是因?yàn)樵摬寮念惣虞d器與部分第三方j(luò)ar包的兼容性問(wèn)題，，several third-party libraries deserialize without considering the context classloader，部分的序列化框架/工具并沒(méi)有序列化的時(shí)候并沒(méi)有考慮使用contextClassLoader，而使用了其他類加載器。
我這個(gè)現(xiàn)像應(yīng)該就是從其他類加載器中的類型，反序列化到context classloader中的類型時(shí)發(fā)生問(wèn)題，
表面看起來(lái)二者的包名類命是一致的，但并不是在同一個(gè)加載器中的類，導(dǎo)致類型轉(zhuǎn)換異常。

因?yàn)槭桥紶柍霈F(xiàn)的怪現(xiàn)像，分析發(fā)現(xiàn)，只要用了默認(rèn)配置的緩存，都會(huì)報(bào)錯(cuò)，發(fā)現(xiàn)該默認(rèn)配置中少了指定的序列化和反序列化，應(yīng)該就是官方提到的類似兼容性問(wèn)題。于是給默認(rèn)配置添加上指定的序列化配置，spring-boot-devtools也能繼續(xù)使用了。
