Jersey clientFilter 过滤

eureka-wiki

POM依赖:

<dependency>     <groupId>com.sun.jersey</groupId>     <artifactId>jersey-client</artifactId>     <version>1.19.1</version> </dependency> 

实现抽象类ClientFilter的handle方法

public class IpCilentFilter extends ClientFilter {     @Override     public ClientResponse handle(ClientRequest clientRequest) throws ClientHandlerException {         //响应对象的处理         ClientResponse response = this.getNext().handle(clientRequest);         return response;     } } 

注入clientFilter

 @Bean public DiscoveryClientOptionalArgs discoveryClientOptionalArgs() {     DiscoveryClientOptionalArgs discoveryClientOptionalArgs = new DiscoveryClientOptionalArgs();     discoveryClientOptionalArgs.setAdditionalFilters(Collections.singletonList(new IpCilentFilter()));     return discoveryClientOptionalArgs; } 

自定义filter过滤

@Bean public FilterRegistrationBean filterRegistrationBean() {     FilterRegistrationBean registration = new FilterRegistrationBean(new ServerRequestAuthFilter());     registration.addUrlPatterns("/*");     return registration; }  public class ServerRequestAuthFilter implements Filter {     @Override     public void doFilter(ServletRequest request, ServletResponse response,                          FilterChain filterChain) throws IOException, ServletException {         //业务实现，根据请求的IP或者参数判断是否可以执行注册或者访问         filterChain.doFilter(request, response);     } } 

拦截具体客户端注册、续约、下线请求，请参考 /eureka/apps

总结：

eureka:   client:     fetch-registry: true 

1. 跟了下源码，第一种clientFilter只支持懒加载模式（版本1.6.2）
2. 自定义filter过滤比clientFilter 更加灵活，因为clientfilter不会限制在eureka-server上的任何东西
