我在练习Spring Boot。我在我的项目中添加了一个安全类，但从那时起我无法访问主页“/”在我添加安全类之前它工作正常，但现在我得到了一个白标签错误页面。
这是我的配置类：

package com.teszt.thymeleaftest.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@EnableWebMvc
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/event**").authenticated()
                .antMatchers("/").anonymous()
                .and()
                .formLogin()
                    .loginPage("/login/login")
                    .loginProcessingUrl("/logIn")
                    .permitAll()
                .and()
                .csrf().disable();
    }
}

这是我的控制器：

package com.teszt.thymeleaftest.controller;

import com.teszt.thymeleaftest.dao.MemberRepository;
import com.teszt.thymeleaftest.entity.Members;

        theModel.addAttribute("members", theMembers);

            return "/login/welcomePage";
        }else{

        }

        return "/login/login";
    }

    @GetMapping("/member")
    public String member(@RequestParam("userId") int theId, Model theModel) {

        //get the employee from the service
        Users theUser = usersService.findById(theId);

        //set employee as a model attribute to pre-populate the form
        theModel.addAttribute("member", theUser);

        return "login/member";

    }

    @PostMapping("/saveMember")

            membersService.save(theMember);

            //delete the user because he/she is a member now
            usersService.deleteByEmail(theUser.getEmail());

            //prevent duplication
            return "redirect:/";
        }

    }

    @GetMapping("/showMemberFormForUpdate")
    public String updateMember(@RequestParam("memberId") int theId, Model theModel){

        //get the employee from the service

这是我的pom的一个简短版本，但我的所有依赖项都在这里
我希望有人能帮助我。
