将log4j2与slf4j一起使用
所以我尝试在他们的网站上遵循这个 （非maven实现）和要求，将slf4j添加到log4j。 并尝试使用此代码
public static void main(String[] args) { Logger logger = LoggerFactory.getLogger(Main.class); logger.info("test"); } 并将以下内容添加到我的库中
- log4j的-API-2.3.jar
- log4j的核心-2.3.jar
- log4j的-sl4j-IMPL-2.3.jar
- log4j的到sl4j-2.3.jar
- SLF4J-API 1.7.12.jar
当我尝试运行它时，我收到以下错误
Exception in thread "main" java.lang.StackOverflowError at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936) at java.util.concurrent.ConcurrentHashMap.containsKey(ConcurrentHashMap.java:964) at org.apache.logging.slf4j.SLF4JLoggerContext.getLogger(SLF4JLoggerContext.java:40) at org.apache.logging.slf4j.Log4jLoggerFactory.newLogger(Log4jLoggerFactory.java:37) at org.apache.logging.slf4j.Log4jLoggerFactory.newLogger(Log4jLoggerFactory.java:29) at org.apache.logging.log4j.spi.AbstractLoggerAdapter.getLogger(AbstractLoggerAdapter.java:47) at org.apache.logging.slf4j.Log4jLoggerFactory.getLogger(Log4jLoggerFactory.java:29) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:284) at org.apache.logging.slf4j.SLF4JLoggerContext.getLogger(SLF4JLoggerContext.java:41) at org.apache.logging.slf4j.Log4jLoggerFactory.newLogger(Log4jLoggerFactory.java:37) at org.apache.logging.slf4j.Log4jLoggerFactory.newLogger(Log4jLoggerFactory.java:29) at org.apache.logging.log4j.spi.AbstractLoggerAdapter.getLogger(AbstractLoggerAdapter.java:47) at org.apache.logging.slf4j.Log4jLoggerFactory.getLogger(Log4jLoggerFactory.java:29) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:284)...
知道我哪里错了吗？
您正在使用log4j-sl4j-impl-2.3.jar和log4j-to-sl4j-2.3.jar创建一个调用循环。
log4j-sl4j-impl-2.3.jar是将slf4j调用发送到log4j的适配器的实现。
log4j-to-sl4j-2.3.jar正在将log4j调用发送回slf4j。 删除这个 。
