Java 无法运行my Spring Security MVC WebApp SpringChainFilter引发异常，密码不能为null

所以我试着做一个简单的spring安全硬编码安全，只是为了在连接到DB之前检查我的应用程序是如何工作的，但在此之前，它开始向我显示错误500

这是我的配置文件

package com.luv2code.springsecurity.demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages="com.luv2code.springsecurity.demo")
public class DemoAppConfig {

    @Bean
    public ViewResolver viewResolver()
    {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/view/");
        viewResolver.setSuffix(".jsp");
        
        return viewResolver;
    }
    
    
}

下面是我的webSecurity配置类，它使用一些示例数据进行内存内身份验证

package com.luv2code.springsecurity.demo.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.User.UserBuilder;


@Configuration
@EnableWebSecurity
public class DemoAppSecurity extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        UserBuilder users = User.withDefaultPasswordEncoder();
        
        auth.inMemoryAuthentication()
            .withUser(users.username("John")).withUser(users.password("test123")).withUser(users.roles("Manager"))
            
            .withUser(users.username("Rando")).withUser(users.password("test123")).withUser(users.roles("Executive"));
    
    
    }

    
    
}

这是我的Servlet初始化器类，我在其中使用基于java的配置，而不是web.xml

package com.luv2code.springsecurity.demo.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class MySpringMvcDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        // TODO Auto-generated method stub
        return new Class[] {DemoAppConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        // TODO Auto-generated method stub
        return new String[] { "/" };
    }

}

这是我的控制器类

package com.luv2code.springsecurity.demo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class DemoController {

    @GetMapping("/")
    public String showHome()
    {
        return "home";
    }
    
}

这是我的Pom文件，我在其中添加了我的从属关系
