java - 主要错误无法找到记录器配置“测试”的附加程序“测试”

Question

这是我的log4j2`JSON配置

{
  "Configuration": {
    "Appenders": {
      "Console": {
        "PatternLayout": {
          "pattern": "%d{yyyy-MMM-dd HH:mm:ss a} [%t] %-5level %logger{36} - %msg%n"
        },
        "name": "Console",
        "target": "SYSTEM_OUT"
      },
      "RollingFile": {
        "name": "general",
        "fileName": "C:/logs/simulator-log.log",
        "filePattern": "C:/logs/simulator-log-%d{yyyy-MM-dd HH-mm-ss}.log",
        "PatternLayout": {
          "pattern": "%msg%n"
        },
        "Policies": {
          "OnStartupTriggeringPolicy": {}
        }
      },
      "File": {
        "PatternLayout": {
          "pattern": "%msg%n"
        },
        "name": "test1",
        "fileName": "c:/logs/response_sent.log"
      }
    },
    "Loggers": {
      "Root": {
        "AppenderRef": [
          {
            "ref": "Console"
          }
        ],
        "level": "trace"
      },
      "logger": [
        {
          "name": "test",
          "level": "trace",
          "additivity": "false",
          "AppenderRef": {
            "ref": "test"
          }
        },
        {
          "name": "test1",
          "level": "trace",
          "additivity": "false",
          "AppenderRef": {
            "ref": "test1"
          }
        },
        {
          "name": "general",
          "level": "trace",
          "additivity": "false",
          "AppenderRef": {
            "ref": "general"
          }
        }
      ]
    }
  }
}

当我使用一个文件附加程序时，它工作正常。当我使用两个文件附加程序得到 title.cant 中提到的错误时，我们添加了超过 1 个文件附加程序。我不想使用滚动文件附加程序。

用于创建记录器变量的 Java 代码

private static final Logger requestsReceived = LogManager.getLogger("test");
private static final Logger responseSent = LogManager.getLogger("test1");
private static final Logger logger = LogManager.getLogger("general");

尝试使用type如下属性定义您的附加程序 -

{
    "type": "File",
    "PatternLayout": {
        "pattern": "%msg%n"
    },
    "name": "test",
    "fileName": "c:/logs/requests_received.log"
},
{
    "type": "File",
    "PatternLayout": {
        "pattern": "%msg%n"
    },
    "name": "test1",
    "fileName": "c:/logs/response_sent.log"
}

为此，您必须使用type属性修改所有附加程序配置。您的完整配置文件将更改如下 -

{
    "Configuration": {
        "Appenders": {
            "appender": [
                {
                    "type": "Console",
                    "PatternLayout": {
                        "pattern": "%d{yyyy-MMM-dd HH:mm:ss a} [%t] %-5level %logger{36} - %msg%n"
                    },
                    "name": "Console",
                    "target": "SYSTEM_OUT"
                },
                {
                    "type": "RollingFile",
                    "name": "general",
                    "fileName": "C:/logs/simulator-log.log",
                    "filePattern": "C:/logs/simulator-log-%d{yyyy-MM-dd HH-mm-ss}.log",
                    "PatternLayout": {
                        "pattern": "%msg%n"
                    },
                    "Policies": {
                        "OnStartupTriggeringPolicy": {

                        }
