Spring Security 4.x -> 5.x 踩坑记录

Lovnx · 2月前 · 920 ·

1、应用服务基路径问题

这个问题应该是Spring Boot 2.0升级带来的,既然遇到了,就在这里写一写。笔者在授权服务器想设置一个统一基路径,按照Spring Boot 1.0,是这样的:

server.context-path=/xxx

但是升级之后并不好使,最后看官方文档发现改掉了,现在是这样的:

server.servlet.context-path=/xxx

2、AuthenticationManager无法注入

在覆写AuthorizationServerConfigurerAdapter类的public void configure(AuthorizationServerEndpointsConfigurer endpoints) 方法时,往往需要显式注入AuthenticationManager ,但是在5.x版本中,启动会报如下错误:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field authenticationManager in cn.springcloud.book.OAuthConfiguration 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:
在启动主类继承WebSecurityConfigurerAdapter 类同时,手动注入:

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

3、登陆报错:There is no PasswordEncoder mapped for the id “null”

在使用Spring Security 5.x登陆页面进行登陆时,后端会报错:There is no PasswordEncoder mapped for the id “null”,因为5.x版本新增了多种密码加密方式,必须指定一种,比如这样解决:

    @Bean
    public static NoOpPasswordEncoder passwordEncoder() {
      return (NoOpPasswordEncoder) NoOpPasswordEncoder.getInstance();
    }

下列加密方式供参考,选取一种即可:

bcrypt - BCryptPasswordEncoder (Also used for encoding)
ldap - LdapShaPasswordEncoder
MD4 - Md4PasswordEncoder
MD5 - new MessageDigestPasswordEncoder("MD5")
noop - NoOpPasswordEncoder
pbkdf2 - Pbkdf2PasswordEncoder
scrypt - SCryptPasswordEncoder
SHA-1 - new MessageDigestPasswordEncoder("SHA-1")
SHA-256 - new MessageDigestPasswordEncoder("SHA-256")
sha256 - StandardPasswordEncoder
