微服务多模块：Springboot+Security+Redis+Gateway+OpenFeign+Nacos+JWT （附源码）仅需一招，520彻底拿捏你

news 2025/6/30 5:58:48

可能有些人会觉得这篇似曾相识，没错，这篇是由原文章进行二次开发的。

前阵子有些事情，但最近看到评论区说原文章最后实现的是单模块的验证，由于过去太久也懒得验证，所以重新写了一个完整的可以跑得动的一个。

OK，回到正题，以下是真正对应的微服务多模块的一个方法，使用到的技术有：基于微服务的Springboot+Security+Redis+Gateway+OpenFeign+Nacos+JWT。

对使用到的微服务技术进行在项目中的说明：

Security：负责登录验证（文章中没有实现授权，在过滤器中直接返回null，如果想实现授权，可以在返回null的地方添加授权信息类似ROLE_ADMIN，同时在Security的配置文件那里添加授权信息即可）。

Redis：负责缓存token跟用户数据。

Gateway：对前端提供的接口，由它多个模块进行接口调用。

OpenFeign：提供给security查询数据库中的用户信息。

Nacos：注册服务中心，注册服务的信息，使OpenFeign可以调用其他服务模块。

注意：虽然是原文章的二次编写，但是很多都不同，建议直接跟着这篇走。

1.项目结构

涉及的模块有

（1）common（Redis配置文件、Redis工具、Token工具、返回给前端信息的工具；即如下文件RedisConfig、RedisUtil、TokenUtil、ResponseUtil）；

（2）gateway；

（3）model（实体类，Feign的客户端）；

（4）service（用户模块、课程模块）；

（5）spring_security（security的过滤器跟配置文件）。

下面小编将全部一一介绍并且源码展示出来。

public interface UserFeign {@GetMapping("/api/user/{username}")public User findUserByName(@PathVariable("username") String username);}

4.service模块

4.1 目录结构

4.2 service_user模块

4.2.1 pom.xml

注意：service_user接入了security模块。

4.2.3 Service_UserApp启动类

@SpringBootApplication
@EnableSwagger2WebMvc
@EnableDiscoveryClient
@EnableFeignClients
@EnableCaching
public class Service_UserApp
{public static void main( String[] args ){SpringApplication.run(Service_UserApp.class, args);}
}

4.2.4 ApiController控制器

在任意一个控制器中，添加如下代码，该接口将用于OpenFeign的远程接口调用，由security模块中的自定义类MyUserDetailService去进行调用。（MyUserDetailService的代码在介绍security模块中会出现）

    @GetMapping("/api/user/{username}")public User findUserByName(@PathVariable("username") String username){User userByName = userService.findUserByName(username);return userByName;}

4.3 其他service模块

对于其他模块，相对应跟service_user模块一样，进行如下操作即可：

（1）在pom.xml中引入security模块

        <!--接入security模块--><dependency><groupId>com.goyes</groupId><artifactId>spring_security</artifactId><version>1.0-SNAPSHOT</version></dependency>

（2）在application.xml中添加以下代码

spring:main:allow-bean-definition-overriding: true

防止出现运行异常报错信息，对于同一个服务的FeignClient来说，配置该属性不会造成覆盖，详情可以查看该文章：Consider renaming one of the beans：

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

}

5.3 WebSecurityConfig（WebSecurityConfigurerAdapter）

注意：前面将对service_user的远程接口定义为/api/user/{username}，所以在过滤方面要放行该路径，否则security无法调用数据库查询用户信息，导致程序报错。

对此，可以查看该文章feign.FeignException$Unauthorized

}

5.4 TokenOncePerRequestFilter（OncePerRequestFilter）

注意：在这里TokenUtil跟RedisUtil对于过期时间的定义不同。

token过期时间为3分钟，redis上存储的异常时间为5分钟，并且redis上存储的刷新时间为7天

在下面的配置文件中，仅仅对token进行分析而已，可以根据需要在这里做验证码校验。

token的过期时间在以下代码中是这样做的，当token过期时间3分钟到了，判断redis上存储的异常时间是否到了5分钟，没到5分钟就返回一个新的token给前端，前端拿到该token就可以继续访问；如果到了5分钟，则会停止访问并通知前端 “用户已经过期，请重新登录”。

小编有个想法（还没做）：在这里可以重新定义过期时间，比如用户每次访问时都进行判断：当token的过期时间小于1分钟后就刷新redis的异常时间，这样可以使当token要过期时，就有新的token出现，但这样操作也存在缺点：就是要消耗内存资源，每次都得去读取token是否临近过期时间了。对于这块，可以针对自己的情况去做调整。

注意：在这里调用了model模块中的UserFeign文件，实现读取service_user模块中的findUserByName方法。
