Question

我正在为我的测试编写自定义AppenderBase并在logback-test.xml中进行配置然而，append（）函数没有被调用。

import ch.qos.logback.core.AppenderBase;
import org.apache.log4j.spi.LoggingEvent;

import java.util.ArrayList;
import java.util.List;

public class TestAppender extends AppenderBase<LoggingEvent> {
    public static List<LoggingEvent> events = new ArrayList<>();

    @Override
    protected void append(LoggingEvent e) {
        events.add(e);
    }
}

这是我的配置文件：logback-test.xml

<?xml version="1.0" encoding="UTF-8" ?>
<configuration scan="false">
    <contextName>logging</contextName>

    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>
                %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{32} - %msg%n
            </pattern>
        </encoder>
    </appender>

    <root level="WARN">
        <appender-ref ref="CONSOLE" />
    </root>

    <logger name="com.egencia.library" level="INFO" />


        
    <appender name="map" class="com.egencia.service.contact.controller.TestAppender" />
        
    <root level="ERROR">
                
        <appender-ref ref="map"/>
            
    </root>


</configuration>

这是我的测试代码

private final static Logger LOGGER = LoggerFactory.getLogger(ServiceController.class);

在我调用的函数中：

LOGGER.error("Unhandled type");

在我的测试中，我检查：

Assert.assertEquals(1, TestAppender.events.size());

这是我的堆栈跟踪：

Answer 1

我使用的是LoggingEvent而不是ILoggingEvent。改变它解决了我的问题。

Answer 2

回溯状态消息表明＆lt; root＆gt; element被放置在一个appender＆lt; element＆gt;里面。在您的配置文件中。这不行。但是，上面的配置文件不会出现此问题，即不的＆lt; root＆gt;元素放在一个appender＆lt; element＆gt;里面。

问题中列出的配置文件和状态消息是否匹配？

另外，您要声明＆lt; root＆gt;元素两次。相反，放置两个＆lt; appender-ref＆gt;一个＆lt; root＆gt;中的元素。

自定义AppenderBase未被调用
