扩展 Log4j2 测试

Question

我有一个 log4j2 记录器的包装器 class - 例如

import org.apache.logging.log4j.core.Logger;
       
public class MyLogger extends Logger {
    protected MyLogger(LoggerContext context, String name, MessageFactory messageFactory) {
        super(context, name, messageFactory);
    }

    ....
    
}

我正在尝试扩展 LoggerTest class 以验证 MyLogger 功能（因此我可以运行包含的测试并添加新的）。我试过类似下面的东西：

@SpringBootTest
@LoggerContextSource(
    value = "log4j-test2.xml",
    reconfigure = ReconfigurationPolicy.AFTER_EACH
)
public class MyLoggerTest extends LoggerTest {
    public MyLoggerTest(LoggerContext context, ListAppender app, ListAppender host, ListAppender noThrown) {
        super(context, app, host, noThrown);
    }
}

org.junit.jupiter.api.extension.ParameterResolutionException: No ParameterResolver registered for parameter [org.apache.logging.log4j.test.appender.ListAppender arg1] in constructor....

我尝试创建 @LoggerContextSource 和属性 resolver/extensions class 的本地实现，它引用 (@Extensions({@ExtendWith({LoggerContextResolver.class}), @ExtendWith({ConfigurationResolver.class}), @ExtendWith({AppenderResolver.class})})) 并引用它们例如

@MyLoggerContextSource(
    value = "log4j-test2.xml",
    reconfigure = ReconfigurationPolicy.AFTER_EACH
)

...
@Extensions({
   @ExtendWith({MyLoggerContextResolver.class}), 
   @ExtendWith({MyConfigurationResolver.class}), 
   @ExtendWith({MyAppenderResolver.class})
})
public @interface MyLoggerContextSource {
...
}

但 LoggerContextResolver 和 MyLoggerContextResolver

出现 Duplicate ParameterResolver... 错误

我是否可以扩展 log4j2 测试？

Answer 1

感谢@rgoers，结果我遗漏了参数上的 @Named 注释。

所以我的 MyLoggerTest 适用于以下内容：

@SpringBootTest
@LoggerContextSource(
    value = "log4j-test2.xml",
    reconfigure = ReconfigurationPolicy.AFTER_EACH
)
public class MyLoggerTest extends LoggerTest {
    public MyLoggerTest(final LoggerContext context, @Named("List") final ListAppender app, @Named("HostTest") final ListAppender host, @Named("NoThrowable") final ListAppender noThrown) {
        super(context, app, host, noThrown);
    }
}
