= Jackson Support |
|
|
|
Spring Security provides Jackson support for persisting Spring Security related classes. |
|
This can improve the performance of serializing Spring Security related classes when working with distributed sessions (i.e. session replication, Spring Session, etc). |
|
|
|
To use it, register the `SecurityJackson2Modules.getModules(ClassLoader)` with `ObjectMapper` (https://github.com/FasterXML/jackson-databind[jackson-databind]): |

mapper.registerModules(modules); |

- spring-security-core (`CoreJackson2Module`) |
|
- spring-security-web (`WebJackson2Module`, `WebServletJackson2Module`, `WebServerJackson2Module`) |
|
- xref:servlet/oauth2/client/index.adoc#oauth2client[ spring-security-oauth2-client] (`OAuth2ClientJackson2Module`) |
|
