jdk16环境下example报错 #633

Closed tsgmq closed 3 years ago

tsgmq commented 3 years ago

com.alipay.sofa.jraft.storage.log.SegmentFile 编译不通过 报错信息 java: 程序包 sun.nio.ch 不可见 (程序包 sun.nio.ch 已在模块 java.base 中声明, 但该模块未将它导出到未命名模块) image

killme2008 commented 3 years ago

应该是误用了，我们改下，您要有兴趣也可以提个修复 PR

fengjiachun commented 3 years ago

这个不是误用，只有 sun.nio.ch.DirectBuffer 有 address() api, DirectByteBuffer 只是包可见级别，外部无法访问

killme2008 commented 3 years ago

我的意思是可以改成反射的方式，不需要强依赖。

tsgmq commented 3 years ago

我的水平太菜了，不会改，麻烦修改下，我重新下载代码

tsgmq commented 3 years ago

Method method = this.buffer.getClass().getMethod("address"); final long address = (long)method.invoke(this.buffer);

fengjiachun commented 3 years ago

我下载个 zulu jdk16 看下怎么改好些

fengjiachun commented 3 years ago

我下载了 jdk16, 发现可以编译，你的报错是你的 idea 报错吧？

fengjiachun commented 3 years ago

本地执行一下 mvn clean compile 看看？如果可以编译，那么可能需要看看怎么修改一下你的 IDE 的配置

closess commented 3 years ago

跟你一样的问题，我用的jdk11,哈哈哈 解决方式：鼠标点击那个报红的区域，然后直接使用’ALT + Enter‘自动修复一下就可以了

killme2008 commented 3 years ago

@tsgmq 这个是你自己实现的吧 TradeSnapshotFile ，不是 jraft 的问题。

closess commented 3 years ago

我的jdk11也不能用。 这种方式应该是只有jdk8可以用，jdk8以上就不能用了。 你可以照我上面的方式修复一下就行了

tsgmq commented 3 years ago

感谢各位指点，主要是SerializerManager.getSerializer(SerializerManager.Hessian2).deserialize(content, clazz.getName()) 这个序列化的不行，本地解决了在服务器jdk16依然不行，我已经换成ProtoStuffSerializer来做序列化和反序列化，通过其他方式解决
