1. 背景
在升级springboot版本从1.5.13到2.2.x的过程中出现问题如下
1 *************************** 2 APPLICATION FAILED TO START 3 *************************** 4 5 Description: 6 7 Field configurers in org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerEndpointsConfiguration required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found. 8 9 The injection point has the following annotations: 10 - @org.springframework.beans.factory.annotation.Autowired(required=true) 11 12 13 Action: 14 15 Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.
2. 解决方案：
添加一下配置类WebSecurityConfig，代码如下：
/** * @Auther: duke * @Date: 2018-11-23 10:36 * @Description:要求用户在进入你的应用的任何URL之前都进行验证 */ @Configuration public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Bean @Override public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); } //....... //要求用户在进入你的应用的任何URL之前都进行验证 //创建一个用户名是“user”，密码是“password”，角色是“ROLE_USER”的用户 //启用HTTP Basic和基于表单的验证 //Spring Security将会自动生成一个登陆页面和登出成功页面 }
