使用log4j2时,报:ERROR:SimpleLoggerContextFactory which does not implement Log4jContextFactory

本文介绍了一种常见的Log4j2初始化错误,即SimpleLoggerContextFactory未实现Log4jContextFactory接口导致的问题,并提供了具体的解决方案,包括在src目录下创建配置文件log4j2.component.properties,并设置正确的loggerContextFactory参数。

异常:ERROR StatusLogger LogManager returned an instance of org.apache.logging.log4j.simple.SimpleLoggerContextFactory which does not implement org.apache.logging.log4j.core.impl.Log4jContextFactory. Unable to initialize Log4j
翻译:错误状态日志记录器LogManager返回org.apache.logging.log4j.simple的实例。SimpleLoggerContextFactory,它没有实现org.apache.log.log4j.core.impl. log4jcontextfactory。无法初始化Log4j

解决:
在src目录下创建一个配置文件,叫:log4j2.component.properties;
内容配置为:log4j2.loggerContextFactory=org.apache.logging.log4j.core.impl.Log4jContextFactory
log4j.configurationFile=/log4j2.xml

### PCIe Signaling Advisory Non-Fatal Error Causes and Solutions #### Overview of Non-Fatal Errors Non-fatal errors are a category of issues that do not cause immediate system failure but indicate potential problems within the PCI Express (PCIe) communication channel or device operation. These errors can be detected through various mechanisms defined by the PCIe specification, including specific registers like "Uncorrectable Error Severity," which allows each uncorrectable error to be classified as either fatal or non-fatal[^2]. #### Common Causes of Non-Fatal Errors Several conditions may lead to signaling advisory non-fatal errors: - **Invalid Request Handling**: When devices receive requests violating their operational rules—such as attempting to read BAR space lengths beyond capabilities—the response might result in an incomplete status message indicating an issue with request processing[^1]. - **Device State Issues**: If a device is already in an erroneous state due to previous failures or misconfigurations, it could fail to respond correctly even when receiving valid commands. - **Access Control Violations**: Requests containing access control service errors will also trigger this type of warning from compliant hardware components. - **Bridge Communication Failures**: In cases where bridges cannot forward transactions successfully because downstream endpoints reject them, these scenarios too contribute towards generating such advisories. ```python def check_non_fatal_error(error_status): """ Checks if given error status indicates a non-fatal condition. Args: error_status (int): Value obtained from Uncorrectable Error Status register Returns: bool: True if error marked as non-fatal; False otherwise """ severity_register = get_uncorrectable_severity() # Hypothetical function call return ((error_status & ~severity_register) != 0) def handle_non_fatal_error(): """Handles identified non-fatal errors appropriately.""" log_event("Detected non-fatal error") # Log event for monitoring purposes reset_device_state() # Attempt recovery without disrupting operations ``` #### Recommended Solutions To address signaling advisory non-fatal errors effectively: - Implement robust logging practices so administrators have visibility into what kinds of events occur frequently enough to warrant investigation. - Develop scripts similar to those shown above to monitor critical registers continuously while providing automated responses aimed at mitigating impacts on overall performance whenever possible. - Regularly update firmware/drivers ensuring compatibility across all connected peripherals thereby reducing chances of encountering unexpected behaviors during runtime. - Consider implementing redundancy strategies wherever applicable especially concerning mission-critical applications relying heavily upon stable interconnectivity between multiple pieces of equipment over extended periods. --related questions-- 1. What tools exist specifically designed for diagnosing PCIe related faults? 2. How does one interpret values found inside different fields contained within Transaction Layer Packets (TLPs)? 3. Can you provide examples illustrating how certain types of malformed packets would manifest themselves under normal operating circumstances? 4. Are there any best practices recommended regarding configuration settings associated with advanced error reporting features supported by modern PCIe implementations?
