java.lang.ClassCastException：org.apache.logging.slf4j.SLF4JLoggerContext不能转换到org.apache.logging.log4j.core.LoggerContext

Question

我试图通过API来创建拼写检查程序，这里是我的代码

SpellCheck.java

package com.spell; 

import org.xeustechnologies.googleapi.spelling.SpellChecker; 
import org.xeustechnologies.googleapi.spelling.SpellCorrection; 
import org.xeustechnologies.googleapi.spelling.SpellResponse; 

public class SpellCheck { 

    public static void main(String[] args) 
    { 

     SpellChecker checker = new SpellChecker(); 

     SpellResponse spellResponse = checker.check("helloo worlrd"); 

     for(SpellCorrection sc : spellResponse.getCorrections()) 
      System.out.println(sc.getValue()); 

    } 
} 

依赖

错误我它运行后得到：

Exception in thread "main" java.lang.ExceptionInInitializerError at com.spell.SpellCheck.main(SpellCheck.java:12) Caused by: java.lang.ClassCastException: org.apache.logging.slf4j.SLF4JLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext at org.apache.log4j.Logger$PrivateManager.getContext(Logger.java:59) at org.apache.log4j.Logger.getLogger(Logger.java:41) at org.xeustechnologies.googleapi.spelling.SpellChecker.(SpellChecker.java:50) ... 1 more

它看起来像org.xeustechnologies.google.api.spelling.SpellChecker使用log4j，你正在使用SLF4J。尝试将log4j-over-slf4j添加到类路径以桥接log4以使用slf4j。
