如何解决spring-security java config：如何配置多个AuthenticationManager实例？

您可以具有多个http配置元素，每个元素都有自己的AuthenticationManager。它可能看起来像这样：

@Configuration
@EnableWebSecurity
public class SecurityConfig {

    @Bean
    private AuthenticationManager authenticationManager1() {
        // defines first AuthenticationManager
        return authenticationManager;
    }

    @Bean
    private AuthenticationManager authenticationManager2() {
        // defines second AuthenticationManager
        return authenticationManager;
    }

    @Configuration
    @Order(1)
    public static class Uri1APIConfigurationAdapter extends WebSecurityConfigurerAdapter {

        @autowired
        @QualifIEr(authenticationManager1)
        private authManager1;

        @OverrIDe
        protected AuthenticationManager authenticationManager() {
            return authManager1;
        }

        protected voID configure(httpSecurity http) throws Exception {
            http
                .antMatcher("/URI1/**")
                ...
        }
    }

    @Configuration
    @Order(2)
    public static class Uri2APIConfigurationAdapter extends WebSecurityConfigurerAdapter {

        @autowired
        @QualifIEr(authenticationManager2)
        private authManager2;

        @OverrIDe
        protected AuthenticationManager authenticationManager() {
            return authManager2;
        }

        protected voID configure(httpSecurity http) throws Exception {
            http
                .antMatcher("/URI2/**")
                ...
        }
    }
}

解决方法

@Override
@Bean( name = "authManager1" )
public AuthenticationManager authenticationManagerBean() throws Exception



@Override
@Bean( name = "authManager2" )
public AuthenticationManager authenticationManagerBean() throws Exception

org.springframework.beans.factory.beanCreationException: Error creaTing bean with name 'springSecurityFilterChain'
