# 一、问题描述 #

idea下使用tomcat，中文日志乱码，如下图所示：

如果直接startup.bat通过启动的话，中文日志乱码的可以参考下这篇文章：[https://blog.csdn.net/u011781521/article/details/116332248][https_blog.csdn.net_u011781521_article_details_116332248]

# 二、解决方法 #

由于我这是在idea里使用tomcat，所以项目的编码用的都是utf-8，此时按如下步骤检查配置即可：

## 1.查看tomcat\\conf\\logging.properties文件中的编码是否为utf-8 ##

java.util.logging.ConsoleHandler.encoding = UTF-8

## 2.idea查看项目编码是否为UTF-8 ##

## 3.tomcat启动参数添加编码 ##

-Dfile.encoding=UTF-8

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTE3ODE1MjE_size_16_color_FFFFFF_t_70 3][]

也可以直接在这添加参数

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTE3ODE1MjE_size_16_color_FFFFFF_t_70 4][]

### 3.修改idea配置文件添加编码，这里修改之后，最好重启下软件 ###

-Dfile.encoding=UTF-8
    -Dconsole.encoding=UTF-8

有个问题就是，修改好之后，打开软件，点击Help，edit custom vm选项查看下上面添加的两个配置是否加进来了，这里有可能没有，没有的话，这里也添加下

此时在idea中再启动tomcat基本上就没啥问题了

我这spring boot用的是logback作为日志，所以如果日志里中文乱码的话，还需要在logback的配置文件中，对输出日志指定下编码：

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
                <encoder>
                    
                    <pattern>%date [%level] [%thread] %logger{80} [%file : %line] %msg%n</pattern>
                    <charset>utf-8</charset>
                </encoder>
            </appender>
