1.修改授权服务器配置

AuthorizationServerConfig.java

/**
 * @author etern
 * @title: AuthorizationServerConfig
 * @projectName springsecurityoauth2-demo
 * @description: TODO 授权服务器配置
 * @date 2022/2/17 15:57
 */
//配置类注解
@Configuration
//启用授权服务器注解
@EnableAuthorizationServer
//继承AuthorizationServerConfigurerAdapter类
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {


    //注入自定义的密码配置
    @Autowired
    private PasswordEncoder passwordEncoder;


    @Autowired
    private AuthenticationManager authenticationManager;


    @Autowired
    private UserService userService;


    /**
     * @return
     * @throws
     * @Author etern
     * @Description //TODO 使用密码模式所需配置
     * @Date 14:29 2022/2/19
     * @Param * @param endpoints
     **/
    //重写configure中参数是endpoints
    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        //密码授权模式是把密码直接传给授权服务器的
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userService);
    }


    //重写configure中参数是clients
    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                //配置client-id
                .withClient("admin")
                //配置client-secret
                .secret(passwordEncoder.encode("112233"))
                //配置访问token的有效时间(秒)
                //.accessTokenValiditySeconds(3600)
                //配置刷新token的有效时间(秒)
                //.refreshTokenValiditySeconds(864000)
                //配置redirect-uri,用于授权成功后跳转
                .redirectUris("http://www.baidu.com")
                //配置申请的权限范围
                .scopes("all")
                //配置grant-type,表示授权类型(授权码模式)
                //.authorizedGrantTypes("authorization_code");
                //授权模式:密码模式
                .authorizedGrantTypes("password");
    }
}

2.SecurityConfig.java中添加一个注入授权的bean

@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
    return super.authenticationManagerBean();
}
