Google App Engine Java 11 无法实例化 com.google.cloud.logging.LoggingHandler

Question

我目前正在测试向 Java 11 的迁移，但我遇到了日志记录组件的问题。 在 Java 8 中，一切都正确记录，具有适当的日志级别并将日志聚合到请求中。 然而，在移动到 Java 11 之后，情况就不再如此了。

我阅读了以下指南： https://cloud.google.com/appengine/docs/standard/java11/writing-application-logs https://cloud.google.com/logging/docs/setup/java#the_javautillogging_handler我对我们的代码进行了必要的更改，现在服务器在初始化时崩溃了。 我收到以下错误：

java.lang.AbstractMethodError: Receiver class com.google.api.gax.grpc.InstantiatingGrpcChannelProvider does not define or inherit an implementation of the resolved method 'abstract com.google.api.gax.rpc.TransportChannelProvider withExecutor(java.util.concurrent .Executor)' 接口 com.google.api.gax.rpc.TransportChannelProvider。 at com.google.api.gax.rpc.ClientContext.create(ClientContext.java:140) at com.google.api.gax.rpc.ClientContext.create(ClientContext.java:123) at com.google.cloud.logging .spi.v2.GrpcLoggingRpc.(GrpcLoggingRpc.java:132) at com.google.cloud.logging.LoggingOptions$DefaultLoggingRpcFactory.create(LoggingOptions.java:61) at com.google.cloud.logging.LoggingOptions$DefaultLoggingRpcFactory.create( LoggingOptions.java:55) at com.google.cloud.ServiceOptions.getRpc(ServiceOptions.java:561) at com.google.cloud.logging.LoggingOptions.getLoggingRpcV2(LoggingOptions.java:129) at com.google.cloud.logging .LoggingImpl.(LoggingImpl.java:109) 在 com.google.cloud.logging.LoggingOptions$DefaultLoggingFactory.create(LoggingOptions.java:46) 在 com.google.cloud.logging.LoggingOptions$DefaultLog ggingFactory.create(LoggingOptions.java:41) at com.google.cloud.ServiceOptions.getService(ServiceOptions.java:541) at com.google.cloud.logging.LoggingHandler.getLogging(LoggingHandler.java:362) at com.google .cloud.logging.LoggingHandler.(LoggingHandler.java:195) at com.google.cloud.logging.LoggingHandler.(LoggingHandler.java:151) at com.google.cloud.logging.LoggingHandler.(LoggingHandler.java:120) at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at java.base/jdk.internal.reflect.

我们的代码最后调用的是：com.altairix.comm.adf.root.log.DefaultLogger.(DefaultLogger.java:26)，它是：

logger = java.util.logging.Logger.getLogger(DefaultLogger.class.getName());

我不确定我的 logging.properties 文件是否正确，但它是从上述指南之一复制的

.level = INFO
io.grpc.netty.level=INFO
sun.net.level=INFO
com.altairix.adf.root.log.ServerLogger.handlers=com.google.cloud.logging.LoggingHandler
com.altairix.comm.adf.root.log.DefaultLogger.handlers=com.google.cloud.logging.LoggingHandler
com.google.cloud.logging.LoggingHandler.log=custom_log
com.google.cloud.logging.LoggingHandler.level=FINEST
default : ERROR
com.google.cloud.logging.LoggingHandler.flushLevel=ERROR
com.google.cloud.logging.LoggingHandler.resourceType=container
com.google.cloud.logging.LoggingHandler.formatter=java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format=%3$s: %5$s%6$s

Answer 1

我能够通过向记录器添加处理程序来解决此问题：

import com.google.cloud.logging.LoggingHandler;
...
logger.addHandler(new LoggingHandler());

并删除对 logging.properties 文件的引用，但我不认为这是预期用途，并且在尝试使用 logging.properties 文件时似乎存在错误
