## Spring MVC project with Java config
2+
3+
This is a simple template for creating issue reproduction projects per
4+
the [README in the root of this repository](https://github.com/spring-projects/spring-framework-issues#readme).
5+
Please review that document before starting.
6+
7+
As described at the link above, do not edit this project directly! Rather
8+
use the `./create-repro-project.sh` script to create a fresh copy to
9+
a new directory having the same name as the JIRA issue you're trying
10+
to reproduce and edit from there.
11+
12+
## Deploying
13+
14+
It is possible to deploy your application directly from the command-line
15+
using maven. See the next two sections on Cargo and Jetty.
16+
17+
### Cargo
18+
19+
You can deploy with the [Cargo Maven plugin](http://cargo.codehaus.org/) which
20+
supports a wide [range of servers](http://cargo.codehaus.org/Containers).
21+
The required command is `mvn package cargo:run`.
22+
23+
By default Cargo is configured to start with `Tomcat 8` but you can easily
24+
edit the plugin settings in `pom.xml` to switch to a different server
25+
and version. The pom.xml or to switch to debug settings.
26+
27+
### Jetty
28+
29+
You can also deploy with the
30+
[Jetty Maven plugin](http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html).
31+
The required command is `mvn jetty:run` or `mvnDebug jetty:run`.
32+
33+
## Logging
34+
35+
This project contains a `log4j.properties` file in `src/main/resources` that you
36+
may wish to configure to emit more detailed logging. The root logger is set to
37+
`INFO` and a custom `org.springframework.web` logger is set to `DEBUG`.
