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
