springboot如何获取前端请求头的值并加入ThreadLocal

依赖：

<dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>1.9.7</version>
</dependency>

示例：

public class ThreadLocalUtil {private static ThreadLocal<String> aaHeaderValueThreadLocal = new ThreadLocal<>();public static void setAAHeaderValue(String aaHeaderValue) {aaHeaderValueThreadLocal.set(aaHeaderValue);}public static String getAAHeaderValue() {return aaHeaderValueThreadLocal.get();}public static void clear() {aaHeaderValueThreadLocal.remove();}
}

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface MyAnnotation {
}

import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;import javax.servlet.http.HttpServletRequest;public class HttpServletRequestUtil {public static String getAAHeaderValue() {HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();return request.getHeader("aaHeader");}
}

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;@Aspect
@Component
public class RequireXXAspect {@Pointcut("@annotation(com.mySpringSecurity.mySpringSecurity.aspect.MyAnnotation)")public void myAnnotationMethod() {}@Before("myAnnotationMethod() && @annotation(requireXX)")public void beforeMethodWithRequireXX(JoinPoint joinPoint, MyAnnotation requireXX) {// 获取aaHeader头的值，这里假设通过ServletRequest获取String aaHeaderValue = HttpServletRequestUtil.getAAHeaderValue();// 将aaHeaderValue存放到ThreadLocal中ThreadLocalUtil.setAAHeaderValue(aaHeaderValue);}
}
