+> 本项目主要为了配合 `jap-ids` 使用，内置了 `IdsAccessTokenFilter`（Access Token 验权过滤器） 和 `IdsUserStatusFilter`（用户登录状态过滤器）
+> 如果不需要该项目中的过滤器，开发者可以自己实现。
+

+
+
+## 配置过滤器
+
+`jap-ids` 默认提供了两类过滤器：
+- Access Token 验权过滤器
+- 用户登录状态过滤器
+
+以本项目为例，配置以下两个过滤器：
+
+### Access Token 验权过滤器
+```java
+@Bean
+public FilterRegistrationBean<IdsAccessTokenFilter> registeraccessTokenFilter() {
+    FilterRegistrationBean<IdsAccessTokenFilter> registration = new FilterRegistrationBean<>();
+    registration.setFilter(new IdsAccessTokenFilter());
+    registration.addUrlPatterns("/*");
+    registration.addInitParameter("ignoreUrl",
+            "/," +
+            "/oauth/login," +
+            "/oauth/error," +
+            "/oauth/confirm," +
+            "/oauth/authorize," +
+            "/oauth/token," +
+            "/oauth/check_session," +
+            "/oauth/registration," +
+            "/.well-known/jwks.json," +
+            "/.well-known/openid-configuration"
+    );
+    registration.setName("IdsAccessTokenFilter");
+    registration.setOrder(1);
+    return registration;
+}
+```
+
+### 用户登录状态过滤器
+```java
+@Bean
+public FilterRegistrationBean<IdsUserStatusFilter> registerUserStatusFilter() {
+    FilterRegistrationBean<IdsUserStatusFilter> registration = new FilterRegistrationBean<>();
+    registration.setFilter(new IdsUserStatusFilter());
+    registration.addUrlPatterns("/*");
+    registration.addInitParameter("ignoreUrl",
+            "/," +
+            "/oauth/login," +
+            "/oauth/error," +
+            "/oauth/confirm," +
+            "/oauth/authorize," +
+            "/oauth/token," +
+            "/oauth/check_session," +
+            "/oauth/registration," +
+            "/.well-known/jwks.json," +
+            "/.well-known/openid-configuration"
+    );
+    registration.setName("IdsUserStatusFilter");
+    registration.setOrder(1);
+    return registration;
+}
+```
