How to solve: Java log error: Record content is garbled
In the Java development process, logs are a very important part, it can help us track and debug the code . However, sometimes when we use the logger, we encounter the problem of garbled recording content. In this article, we will discuss how to solve this problem and provide some code examples.
import java.nio.charset.StandardCharsets; import java.util.logging.ConsoleHandler; import java.util.logging.Handler; import java.util.logging.Logger; public class LogExample { private static final Logger LOGGER = Logger.getLogger(LogExample.class.getName()); public static void main(String[] args) { Handler[] handlers = LOGGER.getHandlers(); for (Handler handler : handlers) { if (handler instanceof ConsoleHandler) { handler.setEncoding(StandardCharsets.UTF_8.name()); } } } }
In this example, we get all the processors of the current logger and iterate over them . We then check if the processor is a console processor and set its encoding to UTF-8.
import org.apache.log4j.Logger; import java.io.UnsupportedEncodingException; public class LogExample { private static final Logger LOGGER = Logger.getLogger(LogExample.class); public static void main(String[] args) { String message = "这是一个示例消息"; try { byte[] bytes = message.getBytes("UTF-8"); String encodedMessage = new String(bytes, "UTF-8"); LOGGER.info(encodedMessage); } catch (UnsupportedEncodingException e) { LOGGER.error("Unsupported encoding: " + e.getMessage()); } } }
In this example, we use the getBytes() method to encode the string in UTF-8 Encoding converted into byte array. Then, convert the byte array back to a string via the new String() method, specifying UTF-8 encoding. Finally, we use a logger to output the converted string.
Summary:
In Java development, it is not uncommon to encounter the problem of garbled Java log record content. To solve this problem, we need to check the encoding format of the log file, set the encoding format of the logger, use the appropriate logger and log output format, and use the character encoding correctly. We hope that the code examples in this article can help readers solve the problem of garbled recorded content in Java log errors. If you still encounter difficulties, it is recommended to consult the relevant official documentation or seek help from the community.
