Tomcat+eclipse+jsp乱码

# [在eclipse中使用Tomcat启动项目乱码](https://www.cnblogs.com/breeze-zZ/p/17614593.html "发布于 2023-08-08 15:49")

修改tomcat的配置文件

1）修改Tomcat的server.xml配置（config目录下）

先找到第一处添加URIEncoding=“UTF-8”

再找到第二处添加URIEncoding=“UTF-8”

2）修改catalina.bat配置（bin目录下）

找到”JAVA_OPTS=%JAVA_OPTS% %JSSE_OPTS%”换行添加

-Dfile.encoding=UTF8 -Dsun.jnu.encoding=UTF8

if not “%JSSE_OPTS%” == “” goto gotJsseOpts
set “JSSE_OPTS=-Djdk.tls.ephemeralDHKeySize=2048”
:gotJsseOpts
set “JAVA_OPTS=%JAVA_OPTS% %JSSE_OPTS%”
-Dfile.encoding=UTF8 -Dsun.jnu.encoding=UTF8
