Tomcat html Chinese garbled solution

The jsp in tomcat will not be garbled, but the Chinese html will be garbled

There are several reasons:

The page encoding is not set. The configuration of tomcat is incorrect. The encoding format for saving the file is not utf. -8 Let’s discuss the solution below

Set the html page to utf-8 Add a tag to the head of the page

Tomcat’s server.xml configuration

(1) Add URIEncoding="UTF-8"

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8"/>

(2) Set catalina.bat (jvm encoding) in tomcat

set "JAVA_OPTS=%JAVA_OPTS% %JSSE_OPTS%" in catalina.bat Add the following: -Dfile.encoding=UTF8 -Dsun.jnu.encoding=UTF8

as shown below:

set "JAVA_OPTS=%JAVA_OPTS% %JSSE_OPTS%"
-Dfile.encoding=UTF8 -Dsun.jnu.encoding=UTF8

(3) Set tomcat's web.xml (mine is about 108 lines ) is modified as follows:

<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>

The above is the solution to solve tomcat garbled code. After configuration, restart tomcat

tomcat restart:

如果你的toamcat已经启动：在命令行中进入tomcat安装目录
C:\tomcat\bin>stutdown
之后 C:\tomcatbin>startup
这样tomcat完成了一次重启。
