我有MasterSecurity配置，这是管理登录的主人。和AdminSecurity配置，管理登录。
当我注解掉一个时，另一个可以工作。但是当我尝试同时使用两个时，主登录显示
不允许PostMapping

package Spring.LoginRegister.Config;

import Spring.LoginRegister.Entity.RolesConstant;
import Spring.LoginRegister.Repository.AdminRepository;
import Spring.LoginRegister.Service.CustomAdminDetailsService;
import lombok.AllArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@EnableWebSecurity
@AllArgsConstructor
@Order(1)
public class AdminSecurityConfig  {

    private final AdminRepository adminRepository;

    @Bean
    public UserDetailsService userDetailsService1(){
        return new CustomAdminDetailsService(adminRepository);
    }

    @Bean
    public BCryptPasswordEncoder passwordEncoder1(){
        return new BCryptPasswordEncoder();
    }

    @Bean
    public DaoAuthenticationProvider authenticationProvider1(){
        DaoAuthenticationProvider authProvider= new DaoAuthenticationProvider();
        authProvider.setUserDetailsService(userDetailsService1());
        authProvider.setPasswordEncoder(passwordEncoder1());
        return authProvider;
    }

    @Bean
    public SecurityFilterChain AdminsecurityFilterChain(HttpSecurity http) throws Exception {
        http
            .authenticationProvider(authenticationProvider1());
        http
            .csrf().disable()
            .authorizeHttpRequests((request) -> request
                .requestMatchers("/AdminDashBoard/**").authenticated()
                .requestMatchers("/admin/login").hasRole(RolesConstant.ROLE_ADMIN.toString() )
                .anyRequest().permitAll()
            )
            .formLogin((form) ->form
                .loginPage("/admin/login")
                .defaultSuccessUrl("/AdminDashBoard", true)                
                .permitAll()
            )
            .logout(form -> form
                .logoutUrl("/logout")
                .invalidateHttpSession(true)
                .clearAuthentication(true)
                .logoutSuccessUrl("/")
            );

        return http.build();
    }
}

我的问题是，当一个从应用程序中删除时，它们都可以单独工作。当我尝试将两者合并时，只有管理配置工作正常。

Method 'POST' is not supported.

这是我的第二个配置：

package Spring.LoginRegister.Config;

import Spring.LoginRegister.Repository.MasterRepository;
import Spring.LoginRegister.Service.CustomAdminDetailsService;
import Spring.LoginRegister.Service.CustomMasterDetails;
import Spring.LoginRegister.Service.CustomMasterDetailsService;

import org.springframework.context.annotation.Configuration;

import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@Order(2)
public class MASTERSecurityConfig  {
    private MasterRepository masterRepository;

    @Bean
    public UserDetailsService userDetailsService2(){
        return new CustomMasterDetailsService(masterRepository);
    }

    @Bean
    @Primary
    public BCryptPasswordEncoder passwordEncoder2(){
        return new BCryptPasswordEncoder();
    }

    @Bean
    public DaoAuthenticationProvider authenticationProvider2(){
        DaoAuthenticationProvider authProvider2= new DaoAuthenticationProvider();
        authProvider2.setUserDetailsService(userDetailsService2());
        authProvider2.setPasswordEncoder(passwordEncoder2());
        return authProvider2;
    }

    @Bean

    public SecurityFilterChain MastersecurityFilterChain(HttpSecurity http) throws Exception {
        http
            .authenticationProvider(authenticationProvider2());
        http
            .csrf().disable()
            .authorizeHttpRequests((request) ->request
                .requestMatchers("/master/home/**").authenticated()
                .requestMatchers("/master/login")
                .hasRole(RolesConstant.ROLE_HOUSEMASTER.toString())
                .anyRequest().permitAll()
            )
            .formLogin((form) ->form
                .loginPage("/master/login")
                .defaultSuccessUrl("/master/home", true)
                .permitAll())
            .logout(form -> form
                .logoutUrl("/logout")
                .invalidateHttpSession(true)
                .logoutSuccessUrl("/")
                .permitAll()
            );

        return http.build();
    }
}

我试过StackOverflow之前的答案。
