如果对你有帮助请给个start，本项目会持续更新，目标是做一个可用的快速微服务开发平台，成为接私活，毕设的开发神器， 欢迎大神们多提意见和建议
使用的都是spring官方最新的版本，版本如下：
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.2.6.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Hoxton.SR3</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-dependencies</artifactId>
<version>2.2.0.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
springcloud gateway进行token校验时使用框架封装好的，不在需要通过自定义过滤器进行认证
引入依赖：
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-oauth2-resource-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-oauth2-jose</artifactId>
</dependency>
</dependencies>
修改配置文件
spring:
security:
oauth2:
resourceserver:
jwt:
jwk-set-uri: http://localhost:8000/public/key.json
增加一个配置文件
package com.digierp.gateway.config;
import com.digierp.gateway.component.PermissionAuthorizationManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.config.web.server.ServerHttpSecurity;
import org.springframework.security.web.server.SecurityWebFilterChain;
/**
* @author liuhao
* @date 2020/4/10
*/
@EnableWebFluxSecurity
public class GateWayWebSecurityConfig {
@Autowired
private PermissionAuthorizationManager permissionAuthorizationManager;
@Bean
public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
http.authorizeExchange()
.pathMatchers("/security/**").permitAll()
.anyExchange().access(permissionAuthorizationManager);
http.oauth2ResourceServer().jwt();
http.csrf().disable();
return http.build();
}
}
需要在网关做权限控制添加ReactiveAuthorizationManager<AuthorizationContext>接口的实现， 如果不需要，请忽略
package com.digierp.gateway.component;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.RandomUtils;
import org.springframework.security.authorization.AuthorizationDecision;
import org.springframework.security.authorization.ReactiveAuthorizationManager;
import org.springframework.security.core.Authentication;
import org.springframework.security.oauth2.jwt.Jwt;
import org.springframework.security.web.server.authorization.AuthorizationContext;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;
/**
* @author liuhao
* @date 2020/4/11
*/
@Slf4j
@Component
public class PermissionAuthorizationManager implements ReactiveAuthorizationManager<AuthorizationContext> {
/**
* 实现权限验证判断
*/
@Override
public Mono<AuthorizationDecision> check(Mono<Authentication> authenticationMono, AuthorizationContext authorizationContext) {
ServerWebExchange exchange = authorizationContext.getExchange();
//请求资源
String requestPath = exchange.getRequest().getURI().getPath();
return authenticationMono.map(auth -> {
new AuthorizationDecision(checkAuthorities(exchange, auth, requestPath));
}).defaultIfEmpty(new AuthorizationDecision(false));
}
//权限校验
private boolean checkAuthorities(ServerWebExchange exchange, Authentication auth, String requestPath) {
Jwt principal = (Jwt) auth.getPrincipal();
log.info("访问的URL是：{}用户信息:{}",requestPath, principal.getClaims().get("user_name"));
return RandomUtils.nextInt() % 2 == 0 ;
}
}
