问题描述:
使用springboot,权限管理使用spring security,使用内存用户验证,但无响应报错:
java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id “null”
在Spring Security 5.0之前,默认值PasswordEncoder是NoOpPasswordEncoder需要纯文本密码。在Spring Security 5中,默认值为DelegatingPasswordEncoder,这需要密码存储格式。
解决方法:
方法一:- 添加密码存储格式,对于纯文本,添加{noop}
修改配置类代码,在密码前面加{noop}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// super.configure(auth);
auth.inMemoryAuthentication()
.withUser("张三").password("{noop}123").roles("vip1","vip2")
.and()
.withUser("李四").password("{noop}123").roles("vip1");
}
方法二:创建MyPasswordEncoder类实现PasswordEncoder,加注解 @Component
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;
@Component
public class MyPasswordEncoder implements PasswordEncoder {
@Override
public String encode(CharSequence charSequence) {
return charSequence.toString();
}
@Override
public boolean matches(CharSequence charSequence, String s) {
return s.equals(charSequence.toString());
}
}
配置类写法:加个.passwordEncoder(new MyPasswordEncoder())
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// super.configure(auth);
auth.inMemoryAuthentication().passwordEncoder(new MyPasswordEncoder())
.withUser("张三").password("123").roles("vip1","vip2")
.and()
.withUser("李四").password("123").roles("vip1");
}
