tomcat8.5 启动控制台日志乱码

使用IDEA在本地启动tomcat进行调试时，发现日志/页面会出现乱码的状况，经过如下方式解决问题。

如下操做所有在Windows10系统中。

• 直接启动tomcat会出现控制台汉字乱码的问题。

这是由于 tomcat启动默认编码 UTF-8，windows系统默认编码市 GBK，因此最简单的方式就是将tomcat的默认编码改成GBK便可。

找到tomcat目录下的 conf/logging.properties 文件，将以下配置修改成GBK

java.util.logging.ConsoleHandler.encoding = GBK

•  Catalina.log 和localhost.log出现乱码状况，能够尝试如下修改

1catalina.org.apache.juli.AsyncFileHandler.level = FINE

1catalina.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs

1catalina.org.apache.juli.AsyncFileHandler.prefix = catalina.

1catalina.org.apache.juli.AsyncFileHandler.encoding = GBK

 

2localhost.org.apache.juli.AsyncFileHandler.level = FINE

2localhost.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs

2localhost.org.apache.juli.AsyncFileHandler.prefix = localhost.

2localhost.org.apache.juli.AsyncFileHandler.encoding = GBK

 

3manager.org.apache.juli.AsyncFileHandler.level = FINE

3manager.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs

3manager.org.apache.juli.AsyncFileHandler.prefix = manager.

3manager.org.apache.juli.AsyncFileHandler.encoding = GBK

 

4host-manager.org.apache.juli.AsyncFileHandler.level = FINE

4host-manager.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs

4host-manager.org.apache.juli.AsyncFileHandler.prefix = host-manager.

4host-manager.org.apache.juli.AsyncFileHandler.encoding = GBK

 

java.util.logging.ConsoleHandler.level = FINE

java.util.logging.ConsoleHandler.formatter = org.apache.juli.OneLineFormatter

java.util.logging.ConsoleHandler.encoding = GBK

•   访问页面乱码

尝试conf/server.xml，在Connector标签中加入 URIEncoding = "UTF-8" ，无效

<Connector connectionTimeout="20000"

     port="8080"

     protocol="HTTP/1.1"

     redirectPort="8443"

     maxPostSize="0"

     URIEncoding="UTF-8"/

修改bin/catalina.bat，可能会致使 tomcat启动异常 ，无效

set “JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG% -Dfile.encoding=UTF-8

最后，修改  conf/web.xml  问题解决

<servlet>

        <servlet-name>default</servlet-name>

        <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>

        <init-param>

            <param-name>debug</param-name>

            <param-value>0</param-value>

        </init-param>

        <init-param>

            <param-name>fileEncoding</param-name>

            <param-value>UTF-8</param-value>

        </init-param>

        <init-param>

            <param-name>listings</param-name>

            <param-value>false</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>
