+### Q：开启了懒加载后，启动报“未能获取有效的上下文处理器”
+开启了`lazy-initialization=true`后，启动报异常 `InvalidContextException`: 未能获取有效的上下文处理器, 配置如下:
+``` yaml
+spring:
+  main:
+    lazy-initialization: true
+```
+原因是sa-token自动配置入口类SaTokenContextRegister被延迟加载了，只需要手动指定懒加载排除掉SaTokenContextRegister就可以了,实现代码如下:
+```java
+@Configuration
+class MyConfiguration {
+    @Bean
+    LazyInitializationExcludeFilter integrationLazyInitExcludeFilter() {
+        return LazyInitializationExcludeFilter.forBeanTypes(SaTokenContextRegister.class);
+    }
+}
+```
