一看就知道怎么搞了吧，不用多少了首先建一个Springboot的Demo工程

首先建立一个BookApplication 代码如下很简单

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
public class BookApplication {

    @RequestMapping(value = "/available")
    public String available() {
        return "Spring in Action";
    }

    @RequestMapping(value = "/checked-out")
    public String checkedOut() {
        return "Spring Boot in Action";
    }

    public static void main(String[] args) {
        SpringApplication.run(BookApplication.class, args);
    }
}

然后在application.properties配置文件配置端口号

spring.application.name=book
server.port=8090

完成

二在建立一个Demo2项目，SimpleFilter可以加也可以不加，

package com.example;

import com.example.filter.SimpleFilter;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.context.annotation.Bean;

@EnableZuulProxy
@SpringBootApplication
public class Demo2Application {

    @Bean
    public SimpleFilter simpleFilter() {
        return new SimpleFilter();
    }

    public static void main(String[] args) {
        SpringApplication.run(Demo2Application.class, args);
    }


}

Filter代码如下

package com.example.filter;

import com.netflix.zuul.ZuulFilter;
import com.netflix.zuul.context.RequestContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.servlet.http.HttpServletRequest;

public class SimpleFilter extends ZuulFilter {

  private static Logger log = LoggerFactory.getLogger(SimpleFilter.class);

  @Override
  public String filterType() {
    return "pre";
  }

  @Override
  public int filterOrder() {
    return 1;
  }

  @Override
  public boolean shouldFilter() {
    return true;
  }

  @Override
  public Object run() {
    RequestContext ctx = RequestContext.getCurrentContext();
    HttpServletRequest request = ctx.getRequest();

    log.info(String.format("%s request to %s", request.getMethod(), request.getRequestURL().toString()));

    return null;
  }

}

最后配置下application.properties

测试访问

http://localhost:8080/books/available

日志

2016-04-15 20:17:36.095 INFO 5033 --- [nio-8080-exec-1] o.s.c.n.zuul.web.ZuulHandlerMapping : Mapped URL path [/books/**] onto handler of type [class org.springframework.cloud.netflix.zuul.web.ZuulController]

2016-04-15 20:17:58.587 INFO 5033 --- [nio-8080-exec-4] com.example.filter.SimpleFilter : GET request to http://localhost:8080/books/available

由结果可以看已经帮你重定向到了8090
