Spring Security已添加Jackson Support以保持Spring Security相关类的持久性。这能够提升在使用分布式会话（即会话复制，Spring会话等）时序列化Spring Security相关类的性能。要使用它，请将JacksonJacksonModules.getModules（ClassLoader）注册为Jackson Modules。

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

要使用它，请将JacksonJacksonModules.getModules（ClassLoader）注册为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);
