        <load-on-startup>4</load-on-startup>

    </servlet>

 <servlet-mapping>
        <servlet-name>ssi</servlet-name>

3.4.Tomcat disables 3DES and DES algorithms:

Find the port configuration in tomcat/conf/server.xml, add Ciphers=””, add supported algorithms here, please do not add unsupported algorithms! as follows:

Ciphers="TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA256,TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_DHE_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_ AES_256_CBC_SHA256,TLS_DHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TL S_ECDHE_RSA_WITH_AES_256_CBC_SHA ,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384"

Just restart Tomcat

4.tomcat configuration Other path access (for disk expansion, directly pointing to the disk to store data)

exist

server.xml originally did not configure maxHttpHeaderSize, the default value is only 4096 bytes (4k)

Modify tomcat request header length limit

Add: maxHttpHeaderSize=”500000″

<Connector connectionTimeout="20000"
           port="8080"
           protocol="HTTP/1.1"
           redirectPort="8443"
           maxHttpHeaderSize="500000"/>
