DUBBO 2.7.12 使用Java -jar 命令启动， 自定义拦截器报错，但使用IDEA启动是正常的

打成的jar包我检查过， META-INF/dubbo/internal/org.apache.dubbo.rpc.filter 文件是存在的。

[CrazyHZM]

确认一下providerTraceFilter 所在的类二进制文件是否有被打进去

打进去了， 这个providerTraceFilter，和 META-INF/dubbo/internal/org.apache.dubbo.rpc.filter 文件我是打在一个jar包中，给另外一个spring boot 的jar项目引用的。

这是providerTraceFilter：

`@Activate(group = {CONSUMER, PROVIDER}, value = VALIDATION_KEY, order = 10000) public class ProviderTraceFilter extends ValidationFilter { private Logger logger = LoggerFactory.getLogger(this.getClass());

// 调用过程拦截
@Override
public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException {
    try {
        //获取session信息
        initSession(invocation);
        return invoker.invoke(invocation);
    }catch (RpcException e) {
        throw e;
    }finally {
    }
}
private void initSession(Invocation invocation) {
    String sessionId = invocation.getAttachment("sessionId");
    String qrCode = invocation.getAttachment("qrCode");
    String openId = invocation.getAttachment("openId");
    if (null != sessionId) {
        MDC.put("sessionId",sessionId);
    }
    if (null != qrCode){
        MDC.put("qrCode", qrCode);
    }
    if (null != openId){
        MDC.put("openId", openId);
    }
}

}`

jar包启动报错问题原因找到了：META-INF/dubbo/internal/org.apache.dubbo.rpc.filter，最后 Filter应该大写，应该是org.apache.dubbo.rpc.Filter，但是直接用IDEA开发工具能正常启动原因还不知道……
