Spring Security（三十四）：10.4 Jackson Support

Posted 2021-01-28 帅S俊

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相关类的持久性。这可以提高在使用分布式会话（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);
