春季安全性:从4.0迁移到5.0-错误-没有为id"null"映射的PasswordEncoder [英] Spring security : migrating 4.0 to 5.0 - Error -There is no PasswordEncoder mapped for the id “null”

问题描述

java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null"
    org.springframework.security.crypto.password.DelegatingPasswordEncoder$UnmappedIdPasswordEncoder.matches(DelegatingPasswordEncoder.java:236)
    org.springframework.security.crypto.password.DelegatingPasswordEncoder.matches(DelegatingPasswordEncoder.java:196)
    org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter$LazyPasswordEncoder.matches(WebSecurityConfigurerAdapter.java:593)

我的代码工作正常，现在我将Spring Security版本从4.0更改为5.0，它无法正常工作

My code was working fine, now i have changes the spring security version from 4.0 to 5.0, its not working

推荐答案

(对于基于Java的代码)，请在代码中进行这些更改并将其更新为

for Java based, make these changes in your code and update it as

@Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
    BCryptPasswordEncoder encoder = passwordEncoder();
    auth.inMemoryAuthentication().withUser("admin").password(encoder.encode("admin")).roles("ADMIN");
}

@Bean
public BCryptPasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
}

或

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

用于XML配置，

<bean id ="passwordEncoder" class = "org.springframework.security.crypto.NoOpPasswordEncoder" factory-method = "getInstance" />
