springcloud -zuul(1-zuul的简单使用)

1.maven引入包

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>

2.配置文件

zuul:
          host:
            socket-timeout-millis: 180000
            connect-timeout-millis: 180000
            max-total-connections: 1000
          #忽略所有服务
          ignoredServices: '*'
          #添加主机头
          addHostHeader: true
          #是否默认支持重试
          retryable: true
          #路由前缀
          prefix: /webmicroservice
          #自定义路由
          routes:
            leaguer:
              path: /leaguer/**
              serviceId: leaguer
              customSensitiveHeaders: true

3.自定义过滤器,都继承zuulFilter,实现其方法

3.1

public class AuthFilter extends ZuulFilter {
                @Override
                public String filterType() {
                    //类型为pre,前置
                    return FilterConstants.PRE_TYPE;
                }
 
                @Override
                public int filterOrder() {
                    //顺序为数字为6
                    return FilterConstants.PRE_DECORATION_FILTER_ORDER + 1;
                }
 
                @Override
                public boolean shouldFilter() {
                    //无条件执行
                    return true;
                }
 
                @Override
                public Object run() {
                    RequestContext context = RequestContext.getCurrentContext();
                    //TODO 实现自己需要执行的逻辑如,鉴定权限相关.....
                    log.info("authFilter----->pre_type----->order=6");
                    return null;
                }
            }

public class LoginPostFilter extends ZuulFilter {
                @Override
                public String filterType() {
                    //类型为post,后置
                    return FilterConstants.POST_TYPE;
                }
 
                @Override
                public int filterOrder() {
                    //顺序为数字为999
                    return FilterConstants.SEND_RESPONSE_FILTER_ORDER - 1;
                }
 
                @Override
                public boolean shouldFilter() {
                    //无条件执行
                    return true;
                }
 
                @Override
                public Object run() {
                    //TODO 实现自己需要执行的逻辑如,登录后做些什么
                    log.info("loginFilter----->post_type----->order=999");
                    return null;
                }
            }

3.2实例化,注入spring容器

@Bean
            public AuthFilter getAuthFilter(){
                return new AuthFilter();
            }
 
            @Bean
            public LoginPostFilter getLoginPostFilter(){
                return new LoginPostFilter();
            }

4.启动服务且发送请求
