環境¶

• CentOS 7
• Tomcat 7

解決策¶

/etc/tomcat/server.xml の 73 行目付近に
URIEncoding="UTF-8" と useBodyEncodingForURI="true" を追記して、Tomcat を再起動で解決

修正後の /etc/tomcat/server.xml から抜粋¶

    <!-- A "Connector" represents an endpoint by which requests are received
         and responses are returned. Documentation at :
         Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
         Java AJP  Connector: /docs/config/ajp.html
         APR (HTTP/AJP) Connector: /docs/apr.html
         Define a non-SSL HTTP/1.1 Connector on port 8080
    -->
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8" useBodyEncodingForURI="true" />

Tomcat 再起動コマンド¶

# systemctl restart tomcat
