# 问题分析 #

初建Spring Cloud OAuth2项目中访问获取access\_token票证的端点/oauth/token时报错，在postman中报如下错误：

{ 
        "error": "unauthorized",
        "error_description": "Full authentication is required to access this resource"
    }

如下图：

java控制台报There is no PasswordEncoder mapped for the id "null"错误，如下：

从中可以看出缺少PasswordEncoder的问题，原因是Spring Cloud OAuth2强制要求使用WebSecurityConfigurerAdapter，而WebSecurityConfigurerAdapter需要依赖PasswordEncoder。

# 问题解决 #

增加配置类继承WebSecurityConfigurerAdapter，并在内部定义PasswordEncoder的Bean，代码如下：

package com.wongoing.oauth2.config;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
    import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
    import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
    import org.springframework.security.crypto.password.PasswordEncoder;
    
    @Configuration
    @EnableWebSecurity
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter { 
    
    	@Bean
    	public PasswordEncoder passwordEncoder() { 
    		return new BCryptPasswordEncoder();
    	}
    }

这样此问题就解决了。
