英文:
Wildlfy CLI debugging in embedded mode
问题
在创建嵌入式服务器时通过 EmbeddedProcessFactory.createStandaloneServer，没有可能启用标准输出回显——不允许使用 --std-out=echo 参数。现在在此服务器上调用 CLI 命令会丢弃所有输出，如果有任何错误消息不具有意义，如何调试这个问题？
英文:
When creating an embedded server via
EmbeddedProcessFactory.createStandaloneServer
there is no possibility to enable stdout echoing - the command --std-out=echo arg is not allowed here.
Now calling CLI commands on this server discards all the output and if any error message is not meaningful, how to debug this?

如果您直接使用WildFly嵌入式服务器，可以通过任何日志管理器来控制日志记录。默认情况下，这将使用JBoss日志管理器。您只需确保logging.properties文件在类路径上。以下是JBoss日志管理器的示例配置：
# 要配置的其他日志记录器名称（根记录器始终已配置）
loggers=
# 根记录器级别
logger.level=INFO
# 根记录器处理程序
logger.handlers=CONSOLE
# 控制台处理程序配置
handler.CONSOLE=org.jboss.logmanager.handlers.ConsoleHandler
handler.CONSOLE.properties=autoFlush
handler.CONSOLE.autoFlush=true
handler.CONSOLE.formatter=PATTERN
# 格式化程序模式配置
formatter.PATTERN=org.jboss.logmanager.formatters.PatternFormatter
formatter.PATTERN.properties=pattern
formatter.PATTERN.pattern=%K{level}%d{HH\:mm\:ss,SSS} %-5p [%c] (%t) %s%e%n
您也可以使用其他日志管理器，例如logback或log4j2。使用Configuration.Builder，您可以设置日志提示。以下是使用log4j2的示例：
final StandaloneServer server = EmbeddedProcessFactory.createStandaloneServer(
Configuration.Builder.of(Path.of("/opt/wildfly-27.0.1.Final"))
.setLoggerHint(Configuration.LoggerHint.LOG4J2)
.build());
try {
server.start();
try (ModelControllerClient client = ModelControllerClient.Factory.create("localhost", 9990)) {
final ModelNode op = Operations.createOperation("read-resource");
op.get("attributes-only").set(true);
System.out.println(client.execute(op));
}
} finally {
server.stop();
}
不要翻译代码部分。

If you're using the WildFly embedded server directly, you can control logging via any log manager. By default this will use the JBoss Log Manager. You'd just need to make sure a logging.properties file is on your class path. Here is an example configuration for the JBoss Log Manager.
# Additional logger names to configure (root logger is always configured)
loggers=
# Root logger level
logger.level=INFO
# Root logger handlers
logger.handlers=CONSOLE
# Console handler configuration
handler.CONSOLE=org.jboss.logmanager.handlers.ConsoleHandler
handler.CONSOLE.properties=autoFlush
handler.CONSOLE.autoFlush=true
handler.CONSOLE.formatter=PATTERN
# Formatter pattern configuration
formatter.PATTERN=org.jboss.logmanager.formatters.PatternFormatter
formatter.PATTERN.properties=pattern
formatter.PATTERN.pattern=%K{level}%d{HH\:mm\:ss,SSS} %-5p [%c] (%t) %s%e%n
You could use a different log manager as well like logback or log4j2. With the Configuration.Builder you'd set the logging hint. Here is an example using log4j2.
<!-- language: lang-java -->
final StandaloneServer server = EmbeddedProcessFactory.createStandaloneServer(
Configuration.Builder.of(Path.of("/opt/wildfly-27.0.1.Final"))
.setLoggerHint(Configuration.LoggerHint.LOG4J2)
.build());
try {
server.start();
try (ModelControllerClient client = ModelControllerClient.Factory.create("localhost", 9990)) {
final ModelNode op = Operations.createOperation("read-resource");
op.get("attributes-only").set(true);
System.out.println(client.execute(op));
}
} finally {
server.stop();
}
