Jackson Support

Spring Security 提供了 Jackson 支持,用于持久存储与 Spring Security 相关的类。在使用分布式会话(即会话复制、Spring Session 等)处理与 Spring Security 相关的类时,这样做可以提高序列化性能。

要使用它,请使用 ObjectMapper ( jackson-databind)向 SecurityJackson2Modules.getModules(ClassLoader) 注册:

  • Java

  • Kotlin

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);
val mapper = ObjectMapper()
val loader = javaClass.classLoader
val modules: MutableList<Module> = SecurityJackson2Modules.getModules(loader)
mapper.registerModules(modules)

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

以下 Spring Security 模块提供 Jackson 支持:

  • spring-security-core (CoreJackson2Module)

  • spring-security-web (WebJackson2Module, WebServletJackson2Module, WebServerJackson2Module)

  • spring-security-oauth2-client (OAuth2ClientJackson2Module)

  • spring-security-cas (CasJackson2Module)
