基于Springboot使用logback的注意事项

@Override
protected String[] getStandardConfigLocations() {
 return new String[] { "logback-test.groovy", "logback-test.xml", "logback.groovy", "logback.xml" };
}

private String[] getCurrentlySupportedConfigLocations() {
 List<String> supportedConfigLocations = new ArrayList<>();
 supportedConfigLocations.add("log4j2.properties");
 if (isClassAvailable("com.fasterxml.jackson.dataformat.yaml.YAMLParser")) {
  Collections.addAll(supportedConfigLocations, "log4j2.yaml", "log4j2.yml");
 }
 if (isClassAvailable("com.fasterxml.jackson.databind.ObjectMapper")) {
  Collections.addAll(supportedConfigLocations, "log4j2.json", "log4j2.jsn");
 }
 supportedConfigLocations.add("log4j2.xml");
 return StringUtils.toStringArray(supportedConfigLocations);
}

Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.apache.logging.slf4j.Log4jLoggerFactory loaded from file:/C:/Users/fyk/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.7/log4j-slf4j-impl-2.7.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.apache.logging.slf4j.Log4jLoggerFactory
