Spring Security（三十四）：10.4 Jackson Support

Spring Security has added 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).

Spring Security已添加Jackson Support以保持Spring Security相關類的持久性。這能夠提升在使用分佈式會話（即會話複製，Spring會話等）時序列化Spring Security相關類的性能。 要使用它，請將JacksonJacksonModules.getModules（ClassLoader）註冊爲Jackson Modules。

To use it, register the  JacksonJacksonModules.getModules(ClassLoader) as  Jackson Modules.

要使用它，請將JacksonJacksonModules.getModules（ClassLoader）註冊爲Jackson Modules。

 

ObjectMapper mapper = new ObjectMapper();
ClassLoader loader = getClass().getClassLoader();
List<Module> modules = SecurityJackson2Modules.getModules(loader);
mapper.registerModules(modules);

// ... use ObjectMapper as normally ...
SecurityContext context = new SecurityContextImpl();
// ...
String json = mapper.writeValueAsString(context);
