I have implemented three microservices. sysadmin is for user management and provides some user identity permission queries. Authentication-server is an authentication service, which implements the normal functions of spring security. But my authentication-server needs to get data from sysadmin. Here I use feign-api. Here I implement a simple client service to get data from sysadmin.
This is the github address of my project
Let me get straight to the point and look at the error reports of my project.

code of bufen sysadmin
//Get user's infamation
@RestController
@RequestMapping(value = "/api")
public class SysUserController {
@Autowired
SysUserMapper sysUserMapper;
/**
* 返回用户信息
*/
@GetMapping(value = "/finUserById/{userId}")
public SysUser finUserById(@PathVariable("userId") String userId){
return sysUserMapper.findUserById(userId);
}
}
I think pom.xml and other configurations are fine, so I omitted them.
Then there is the feign-api service：
//Interface to obtain resources
@FeignClient(value = "sysadmin")
public interface SysAdminClient {
@GetMapping(value = "finUserById/{userId}")
SysUser finUserById(@PathVariable("userId") String userId);
@GetMapping(value = "/findRolesByUserId/{userId}")
List<SysRole> findRolesByUserId(@PathVariable("userId") String userId);
@GetMapping(value="/findPermissionByUserId/{userId}")
List<SysPermission> findPermissionByUserId(@PathVariable String userId);
}
Then there is the authentication service.I think there is a big problem here, because I really don’t know how to write. This is a simple case from the official website.

// 根据登录方式，查询用户

// 如果是用户名登录

//判断该账号是否存在
if(sysUser == null) {
System.out.println("用户：" + userId + "不存在");
//用户不存在
throw new UsernameNotFoundException("用户名或密码错误");
}
//开始查询已登录的用户的权限集合
String sysUserId = String.valueOf(sysUser.getId());
//查询角色
List<SysRole> roles = sysAdminClient.findRolesByUserId(sysUserId);
System.out.println("roles:"+roles);
//查询权限
List<SysPermission> permissions = sysAdminClient.findPermissionByUserId(sysUserId);
//定义一个字符串泛型的List集合
List<String> authorities = new ArrayList<>();
for(SysRole role : roles){
//角色名称纳入权限管理，必须增加前缀 ROLE_
authorities.add("ROLE_" + role.getRoleName());
}
for(SysPermission permission : permissions){
//权限字符串描述，不需要特定的任何前后缀
authorities.add(permission.getPermit());
}
System.out.println("sysAccount:"+ sysUser);
//返回UserDetails接口类型对象
return new User(
userId,//登录用户的账号
sysUser.getPassword(),//登录密码，是服务端存储的密文
AuthorityUtils.createAuthorityList(authorities.toArray(new String[0]))//通过工具把字符串权限转换为Security定义的权限
);
}
}
I really don’t know what to do now, I have a headache from learning.
