今天在实现SpringSecurity 集成多种认证方式：密码模式+ 验证码模式 时，密码模式正常返回执行并返回Token ，验证码模式：总是提示上述错误信息：ProviderNotFoundException: No AuthenticationProvider found for \*\*\*\*

问题解决:

报错代码发生在:ProviderManager.authenticate()方法的235行，错误源码输出如下:

源码上已经标识产生错误的原因: provider.authenticate(authentication) 代码中provider 为null 或者parent.authenticate(authentication) 代码中 parent 为空触发错误信息。

ProviderManager.java 类实例化详解分析：

第一步:WebSecurityConfigurerAdapter适配器类中有一个config方法

@Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {
            // 加入自定义的安全认证
            auth.userDetailsService(this.authUserDetailsService)
                    .passwordEncoder(this.passwordEncoder())
                 .and()
                    .authenticationProvider(smsAuthenticationProvider())
                    .authenticationProvider(authenticationProvider());
        }

第二步：可以通过AuthenticationManagerBuilder对象的authenticationProvider方法添加AuthenticationProvider认证对象，看下authenticationProvider方法：

private List<AuthenticationProvider> authenticationProviders = new ArrayList<>();
    	public AuthenticationManagerBuilder authenticationProvider(
    			AuthenticationProvider authenticationProvider) {
    		this.authenticationProviders.add(authenticationProvider);
    		return this;
    	}

第三步:上面的是将AuthenticationProvider对象加入认证链中，下面的代码就是创建ProviderManager对象并初始化认证连：

@Override
    	protected ProviderManager performBuild() throws Exception {
    		if (!isConfigured()) {
    			logger.debug("No authenticationProviders and no parentAuthenticationManager defined. Returning null.");
    			return null;
    		}
    		ProviderManager providerManager = new ProviderManager(authenticationProviders,
    				parentAuthenticationManager);
    		if (eraseCredentials != null) {
    			providerManager.setEraseCredentialsAfterAuthentication(eraseCredentials);
    		}
    		if (eventPublisher != null) {
    			providerManager.setAuthenticationEventPublisher(eventPublisher);
    		}
    		providerManager = postProcess(providerManager);
    		return providerManager;
    	}

通过上述三步,完成ProviderManager 实例化过程。

错误代码:

WebSecurityConfig 配置:

@Configuration
    @EnableWebSecurity
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    	@Autowired
    	@Qualifier("userDetailServiceImpl")
    	private UserDetailsService userDetailService;
    
       /**
    	 * 自定义Provider
    	 */
    	@Autowired
    	private VerificationCodeProvider verificationCodeProvider;
    	
    	 /**
         * 认证
         *
         * @return
         */
        @Bean
        public AuthenticationProvider authenticationProvider() {
            DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
            //对默认的UserDetailsService进行覆盖
            authenticationProvider.setUserDetailsService(userDetailService);
            authenticationProvider.setPasswordEncoder(new PasswordEncoder() {
     
                // 对密码未加密
                @Override
                public String encode(CharSequence rawPassword) {
                    return rawPassword.toString();
                }
     
                // 判断密码是否正确, rawPassword 用户输入的密码,  encodedPassword 数据库DB的密码,当 userDetailService的loadUserByUsername方法执行完后执行
                @Override
                public boolean matches(CharSequence rawPassword, String encodedPassword) {
                	return rawPassword.toString().equalsIgnoreCase(encodedPassword);
                }
            });
            return authenticationProvider;
        }
    
       
    }

在上述配置文件中，定义了两个Provider 但是在代码跟踪中仅仅发现DaoAuthenticationProvider 实例化成功，另外一个失败

正确代码:

WebSecurityConfig 配置:

@Configuration
    @EnableWebSecurity
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    	@Autowired
    	@Qualifier("userDetailServiceImpl")
    	private UserDetailsService userDetailService;
    	
    	
    	
    	/**
    	 * 自定义Provider
    	 */
    	@Autowired
    	private VerificationCodeProvider verificationCodeProvider;
    	
    
    	
    	 /**
         * 认证
         *
         * @return
         */
        @Bean
        public AuthenticationProvider authenticationProvider() {
            DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
            //对默认的UserDetailsService进行覆盖
            authenticationProvider.setUserDetailsService(userDetailService);
            authenticationProvider.setPasswordEncoder(new PasswordEncoder() {
    
                // 对密码未加密
                @Override
                public String encode(CharSequence rawPassword) {
                    return rawPassword.toString();
                }
    
                // 判断密码是否正确, rawPassword 用户输入的密码,  encodedPassword 数据库DB的密码,当 userDetailService的loadUserByUsername方法执行完后执行
                @Override
                public boolean matches(CharSequence rawPassword, String encodedPassword) {
                	return rawPassword.toString().equalsIgnoreCase(encodedPassword);
                }
            });
            return authenticationProvider;
        }
        
    
    	@Override
    	protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    		// TODO Auto-generated method stub
    		auth.authenticationProvider(authenticationProvider());
    		auth.authenticationProvider(verificationCodeProvider);
    	}
    }
