Spring需要一个'AuthenticationManager'类型的bean [英] Spring required a bean of type 'AuthenticationManager'

问题描述

我一直在尝试按照教程

AuthApplication.java

  package com.spud.auth; 
 
 import org.springframework.beans.factory.annotation.Autowired; 
 import org.springframework.boot.SpringApplication; 
 import org.springframework.boot.autoconfigure.SpringBootApplication; 
 import org.springframework.context.annotation.Configuration;

 import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer; 
 
 @SpringBootApplication 
 @EnableResourceServer 
 public class AuthApplication {
 
 public static void main（String [] args）{
 SpringApplication.run （AuthApplication.class，args）; 
} 
 
 @Configuration 
 protected static class LoginConfig extends WebSecurityConfigurerAdapter {
 
 @Override 
 protected void configure（HttpSecurity http）throws Exception { 
 http.requestMatchers（）。antMatchers（/ login，/ oauth / authorize）。和（）。authorizeRequests（）。anyRequest（）
 .authenticated（）。和（）。formLogin （）.permitAll（）; 
} 
 
 @Override 
 protected void configure（AuthenticationManagerBuilder auth）抛出异常{
 auth.inMemoryAuthentication（）。withUser（user）。password（password ）.roles（ USER）; 
} 
} 
 
 @Configuration 
 @EnableAuthorizationServer 
 protected static class OAuth2Config extends AuthorizationServerConfigurerAdapter {
 @Autowired 
 private AuthenticationManager authenticationManager ; 
 
 @Override 
 public void configure（ClientDetailsS​​erviceConfigurer clients）抛出异常{
 clients.inMemory（）。withClient（foo）。secret（bar）
 .authorizedNCrantTypes（authorization_code，refresh_token，password）。scopes（user_info）
 .autoApprove（true）; 
} 
 
 @Override 
 public void configure（AuthorizationServerSecurityConfigurer oauthServer）抛出异常{
 oauthServer.tokenKeyAccess（permitAll（））。checkTokenAccess（isAuthenticated（） ）; 
} 
 
 @Override 
 public void configure（AuthorizationServerEndpointsConfigurer端点）抛出异常{
 endpoints.authenticationManager（authenticationManager）; 
} 
} 
} 
  

UserController.java

  package com.spud.controllers; 
 
 import java.security.Principal; 
 
 import org.springframework.web.bind.annotation.GetMapping; 
 import org.springframework.web.bind.annotation.RestController; 
 
 @RestController 
 public class UserController {
 
 @GetMapping（/ user / me）
 public Principal user（Principal principal）{
返还本金; 
} 
} 
  

application.properties

  server.context-path = / sso-server 
  

错误给定（运行时没有完整的控制台输出，但这是错误）

描述：
 
 com.spud.auth中的字段authenticationManager .AuthApplication $ OAuth2Config需要一个无法找到的类型为'org.springframework.security.authentication.AuthenticationManager'的bean。 
 
 
操作：
 
考虑在配置中定义类型为'org.springframework.security.authentication.AuthenticationManager'的bean。 
  

解决方案

您必须公开 AuthenticationManager 作为spring bean描述此处。

I have been trying to follow a tutorial found HERE for setting up a demo to help me understand SSO on my local machine before implementing in another project. I have run into a problem that has left me stuck. I receive and error telling me to add a bean. Please let me know what code I am missing. I cannot get the program to run.

Description:

Field authenticationManager in com.spud.auth.AuthApplication$OAuth2Config required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.

解决方案

You have to expose the AuthenticationManager as spring bean described here.
