spring cloud集成springsecurity

参考github上yjmyzz的开源项目

新建三个项目：

• demo-server 服务端做security验证
• demo-client 客户端使用feign调用server端接口
• demo-gateway 网关层访问server端接口

1、demo-server项目：

• 1.1、pom.xml引入如下依赖：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

• 1.2、application.yml加入如下配置：

security:
  basic:
    enabled: true
  user:
    name: app01
    password: passwd01

• 1.3、启动工程后访问接口会出现下图：

2、demo-client项目：

• 2.1、feignclient客户端加入BasicAuth授权信息：

@FeignClient(value = "demo-server", configuration = BasicAuthConfiguration.class)
public interface SimpleClient {
}

• 2.2、BasicAuthConfiguration类如下

import feign.auth.BasicAuthRequestInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class BasicAuthConfiguration {
    @Bean
    public BasicAuthRequestInterceptor basicAuthorizationInterceptor() {
        return new BasicAuthRequestInterceptor("app01", "passwd01");
    }
}

• 2.3、启动demo-client，调用demo-server接口能正常调通

3、demo-gateway网关项目：

• 3.1、新建AccessFilter extends ZuulFilter，在run方法里加入Authorization的授权信息：

 public Object run() {
        RequestContext ctx = RequestContext.getCurrentContext();
        HttpServletRequest request = ctx.getRequest();
        //添加Basic Auth认证信息
        ctx.addZuulRequestHeader("Authorization", "Basic " + getBase64Credentials("app01", "passwd01"));
        return null;
    }
private String getBase64Credentials(String username, String password) {
        String plainCreds = username + ":" + password;
        byte[] plainCredsBytes = plainCreds.getBytes();
        byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
        return new String(base64CredsBytes);
    }

• 3.2、application.ym里面加入：

zuul:
  routes:
    api-demo1:
      path: /demo-server/**
      sensitiveHeaders: Cookie,Set-Cookie,Authorization
      serviceId: demo-server

• 3.3、启动gateway工程，就可以访问server的接口了
