当使用 Quarkus rest 数据 Panache 如何在 @PrePersist 中从请求 header 访问用户名

Question

我正在尝试记录修改实体的用户。 反向代理在请求 header 中设置用户名。

当使用 rest Panache 公开 JAX-RS CRUD 时，如何从独立的 class 读取请求和标头

下面是我尝试过的示例，但我得到 null 或 null 指针 exep

package org.acme.manrest;

import javax.enterprise.context.RequestScoped;
import javax.persistence.PrePersist;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.HeaderParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.HttpHeaders;

import org.acme.jpa.TBusiness;
import org.jboss.logging.Logger;

@RequestScoped
public class HeaderValue {
  private static final Logger LOG = Logger.getLogger(HeaderValue.class);

  @Context
  HttpServletRequest request;

  public HttpServletRequest getRequest() {
    return request;
  }

  @Context
  HttpHeaders httpHeaders;

  @HeaderParam("x-remote-user")
  String userName;

  public String getUserName() {
    LOG.info("xxx: " + getRequest().getHeader("x-remote-user"));
    LOG.info("userName: " + userName);
    LOG.info("getUserName2: " + getUserName2());
    LOG.info("getUserName3: " + getUserName3());
    return userName;
  }

  public String getUserName2() {
    return httpHeaders.getRequestHeader("x-remote-user").get(0);
  }

  public String getUserName3() {
    LOG.info("getUserName from class " + request.getHeader("x-remote-user"));
    return request.getHeader("x-remote-user");
  }

  @PrePersist
  void onPrePersist(TBusiness myEntity) {
    LOG.info("getUserName: " + userName);

    myEntity.createdBy = userName;
    myEntity.updatedBy = userName;
  }

}

在 Quarkus 中切换到 JWT 并使用 JWT RBAC 是否可以解决？

Answer 1

通过添加 undertow 依赖项使其工作：

    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-undertow</artifactId>
    </dependency>

然后在PrePersist方法下创建的EntityListener class 中：

@RequestScoped
// @Path("api/v1/Header")
public class AuditingEntityListener {
  private static final Logger LOG = Logger.getLogger(AuditingEntityListener.class);

  // Inject the bean so that Quarkus does not remove it at build time (IMPORTANT)
  @Inject
  HttpServletRequest requestNotUsed;

  @PrePersist
  void onPrePersist(TBusiness myEntity) {
    HttpServletRequest HSR = CDI.current().select(HttpServletRequest.class).get();
    LOG.info("HSR getRequestHeader user: " + HSR.getHeader("x-remote-user"));
  }
}

在 Quarkus 中使用 JWT RBAC 也可以：

  @PrePersist
  void onPrePersist(TBusiness myEntity) {
    JsonWebToken context = CDI.current().select(JsonWebToken.class).get();
    LOG.info("context: " + context.getClaim("preferred_username"));
  }
