Change Jetty default port

Question

Jetty default port is 8080, but I want to change to default port to some other port (9999).

I read a few tutorials and they said almost all of configuration information is by default maintained in file jetty.xml , this file is located under $JETTY_HOME/etc/ . Then, change property jetty.port to 9999. However, when I opened up that file, I couldn't find jetty.port property inside the jetty.xml . I'm currently using Jetty-9.2.1 and the port is at 8080.

I found jetty.port property under jetty-http.xml file. Even though I changed the port to 8090 in the jetty-http.xml file, jetty is still running at port 8080.

I was also advised to use an integration test to configure Jetty to use other port. There's a integration-tests.properties file inside the project. Maybe a solution is to set jetty.port to 9999 inside this file?

integration-tests.properties:

host = localhost
port = 9999

Answer 1

如果在从命令行启动它时设置端口，它是否有效，如下所示：

java -jar start.jar -Djetty.port=9999

Answer 2

I did this in Jetty 9.x version. You need to go to $JETTY_HOME/start.ini file and edit this setting jetty.port .

Lets say that you want to run jetty at 9090 port: Please change jetty.port setting in $JETTY_HOME/start.ini from

jetty.port=8080

to

 jetty.port=9090

Then start jetty using java -jar start.jar option. Then jetty will be running at 9090 port than default 8080 port. Then do curl -i -XGET "http://localhost:9090" . That should give you 200 http status.

Thats it.

Answer 3

Update:

On Jetty 9.x, jetty.port has been deprecated and you can use jetty.http.port instead, as shown below:

$> cd $JETTY_HOME && java -jar start.jar -Djetty.http.port=8080

Answer 4

On jetty 9.2.3.v20140905 it`s need to write in /etc/default/jetty

# JETTY_ARGS
#   The default arguments to pass to jetty.
#   For example
JETTY_ARGS="jetty.port=8080 jetty.spdy.port=8443 jetty.secure.port=443"

but this change only http port. To change https port in jetty 9.2 create ini file $JETTY_HOME/start.d/https.ini

# Initialize module https
#
--module=https
## HTTPS Configuration
# HTTP port to listen on
https.port=8443
# HTTPS idle timeout in milliseconds
https.timeout=30000
# HTTPS Socket.soLingerTime in seconds. (-1 to disable)
# https.soLingerTime=-1

jetty 9.3 in /etc/default/jetty

# JETTY_ARGS
# The default arguments to pass to jetty.
# For example
JETTY_ARGS="jetty.http.port=8080 jetty.ssl.port=443"

or command line parameters -Djetty.http.port=8080 -Djetty.ssl.port=443

Answer 5

我成功地改变了端口，你可以尝试编辑jetty.port位于文件$Jetty_home/start.d/http.ini 。

Answer 6

You need to change the http port in the start.ini file because it will over-right jetty-http.xml config.Or just comment the line in start.ini and keep your config from jetty-http.xml. In [jetty home]/start.ini

## HTTP port to listen on
#jetty.port=8080

Answer 7

只是为了在码头 7 上的完整性，你可以使用这个：

java -jar start.jar --module=http jetty.port=9080

Answer 8

If you are using eclipse you need to set the run configurations. When you install jetty in eclipse, the default port for jetty is 8080 .

So you need to change it into an XML file. If the problem remains, you need to change it in eclipse run configurations.

I hope it works, as it worked for me.

Answer 9

For IntelliJ, this can be done similar to Magnus Lassi's command-line answer.

Run --> Edit Configurations --> Add "-Djetty.port=XXXX", eg:

jetty:run-war -Djetty.port=9999

Answer 10

For SSL port you can pass the param:

-Dssl.port=8445

It worked for me.

Answer 11

for a spring boot application, inside your application.properties file 
add server.port = preferred port number eg. 8082

Answer 12

I changed the jetty.http.port property in jetty/start.ini and it worked for me!

Answer 13

For changing SSL port, you need to change jetty.ssl.port property in below directory:

• $JETTY_HOME/etc
  • jetty-ssl.xml

<Configure id="Server" class="org.eclipse.jetty.server.Server">
...
  <Call  name="addConnector">
    <Arg>
      <New id="sslConnector" class="org.eclipse.jetty.server.ServerConnector">
      ...
        <Set name="port"><Property name="jetty.ssl.port" deprecated="ssl.port" default="8443" /></Set>
      ...
      </New>
    </Arg>
  </Call>
...
</Configure>
