我正在练习Spring Boot。我在我的项目中添加了一个安全类，但从那时起，我就不能到达主页面"/"了，在我添加安全类之前，它还能工作，但现在我得到了一个白标错误页面。
下面是我的配置类。
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();
}
}
这里是我的控制器。

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
Members theMember = membersService.findById(theId);
//set employee as a model attribute to pre-populate the form
theModel.addAttribute("member", theMember);
return "login/updateMember";
}
@PostMapping("/update")

/*if(tempMember != null){

membersService.save(theMember);

return "redirect:/login/login";
}
@GetMapping("/delete")
public String deleteMember(@RequestParam("memberId") int theId){
//delete the employee
membersService.deleteById(theId);
//redirect to index
return "redirect:/";
}
}

我希望有人能帮助我。
