quartz在job中调用Feign报空指针

Question

在Spring中使用quartz，job触发时需要使用Feign调用一个额外的服务，但此时会报空指针（NullPointerException），请问如何处理？

Feign接口类似：

@FeignClient(name = "people-res")
public interface PeopleClient {
    // 不需要验证的普通接口
    @GetMapping("/people")
    public String peopleCheck() throws Exception;
}

调用方法类似：

public class PeopleJob implements Job {

    // 已经知道这样写无法注入，但用一般的直接在Spring容器中取Bean的方式取不到Feign接口类
    @Resource
    private PeopleClient peopleClient;

    public void execute(JobExecutionContext context) throws JobExecutionException {
      ...
      String id = peopleClient.peopleCheck(); // <-- 报错
      ...

报错为：

java.lang.NullPointerException

    at feign.SynchronousMethodHandler.targetRequest(SynchronousMethodHandler.java:176)

网上代码不很多嘛，自己去继承SpringBeanJobFactory，重写createJobInstance方法，这样生成的bean就能注入对象了
