我在 Spring Boot 2 应用程序中使用 LogBack，并且正在尝试配置控制台附加程序，但它给了我以下错误：
Description:
Parameter 1 of method consoleAppender in com.thalasoft.user.rest.config.LogWeb required a bean of type 'ch.qos.logback.classic.encoder.PatternLayoutEncoder' that could not be found.
Action:
Consider defining a bean of type 'ch.qos.logback.classic.encoder.PatternLayoutEncoder' in your configuration.
但是我确实指定了这样一个bean：
@Configuration
public class LogWeb {
private final static String PATTERN = "%date %-5level [%thread] %logger{36} %m%n %rEx";
@Bean
public static LoggerContext loggerContext() {
return (LoggerContext) LoggerFactory.getILoggerFactory();
}
@Bean
public static PatternLayoutEncoder encoder (LoggerContext ctx) {
PatternLayoutEncoder encoder = new PatternLayoutEncoder();
encoder.setContext(ctx);
encoder.setPattern(PATTERN);
return encoder;
}
@Bean (initMethod = "start", destroyMethod = "stop")
public static ConsoleAppender<ILoggingEvent> consoleAppender (LoggerContext loggerContext, PatternLayoutEncoder encoder) {
ConsoleAppender<ILoggingEvent> consoleAppender = new ConsoleAppender<ILoggingEvent>();
consoleAppender.setContext(loggerContext);
consoleAppender.setEncoder(encoder);
return consoleAppender;
}
@Bean (initMethod = "start", destroyMethod = "stop")
public static FileAppender<ILoggingEvent> fileAppender(LoggerContext loggerContext, PatternLayoutEncoder encoder) throws IOException {
RollingFileAppender<ILoggingEvent> fileAppender = new RollingFileAppender<ILoggingEvent>();
fileAppender.setContext(loggerContext);
fileAppender.setEncoder(encoder);
fileAppender.setFile("build.log");
return fileAppender;
}
@Bean
public Logger registerApplicationLogger(LoggerContext loggerContext, ConsoleAppender<ILoggingEvent> consoleAppender, FileAppender<ILoggingEvent> fileAppender) throws IOException {
Logger logger = loggerContext.getLogger("com.thalasoft.user.rest");
logger.setLevel(Level.DEBUG);
logger.addAppender(consoleAppender);
logger.addAppender(fileAppender);
return logger;
}
@Bean
public Logger registerSpringLogger(LoggerContext loggerContext, ConsoleAppender<ILoggingEvent> consoleAppender, FileAppender<ILoggingEvent> fileAppender) throws IOException {
Logger logger = loggerContext.getLogger("org.springframework");
logger.setLevel(Level.DEBUG);
logger.addAppender(consoleAppender);
logger.addAppender(fileAppender);
return logger;
}
}
我正在使用Spring Boot 2.0.3.
