详解SpringBoot 解决拦截器注入Service为空问题

一、自定义拦截器实现 handlerinterceptor 接口

/**
 * 
 * created by zhh on 2018/04/20.
 */
public class myinterceptor implements handlerinterceptor {

 @autowired
 private networkproxyinfoservice networkproxyinfoservice;
 
 @override
 public void aftercompletion(httpservletrequest arg0, httpservletresponse arg1, object arg2, exception arg3)
   throws exception {
  // todo auto-generated method stub
 }

 @override
 public void posthandle(httpservletrequest arg0, httpservletresponse arg1, object arg2, modelandview arg3)
   throws exception {
  networkproxyinfoservice.getallnetworkproxyinfobyisvalid(gobalconstant.proxyvalid.valid);
 }

 @override
 public boolean prehandle(httpservletrequest arg0, httpservletresponse arg1, object arg2) throws exception {
  // todo auto-generated method stub
  return true;
 }
}

二、自定义拦截器配置

/**
 * 
 * created by zhh on 2018/04/20.
 */
@configuration
public class mywebmvcconfig extends webmvcconfigureradapter {
 
 /**
  * 将自定义拦截器作为bean写入配置
  * @return
  */
 @bean
 public myinterceptor myinterceptor() {
  return new myinterceptor();
 }

 @override
 public void addinterceptors(interceptorregistry registry) {
  /**
   * 多个拦截器组成一个拦截器链
   * addpathpatterns 用于添加拦截规则
   * excludepathpatterns 用户排除拦截
   */
  registry.addinterceptor(myinterceptor()).addpathpatterns("/**");
  super.addinterceptors(registry);
 } 
}
