WebSecurityConfigurerAdapter除了包含的类的软件包以外，我在其他软件包中具有extendend
@SpringBootApplication。然后，它无法生成其默认的用户名和密码。

当它在同一包中时，它工作正常。

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;



@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

扩展 WebSecurityConfigurerAdapter的* 类 *

package com.securitymodule;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@Configuration
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // TODO Auto-generated method stub
        super.configure(http);
        http.antMatcher("/**").authorizeRequests().anyRequest().hasRole("USER").and().formLogin();
    }


    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
        .inMemoryAuthentication()
        .withUser("user").password("password").roles("USER");
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        // TODO Auto-generated method stub
        super.configure(auth);
        auth.
        inMemoryAuthentication()
        .withUser("user").password("password").roles("USER");
    }


}
