java - java拆分类时spring失败

Question

我已经为前端和后端创建了带有两个配置子类的 spring 安全配置类。

@EnableWebSecurity
public class SecurityConfig {

    private static AuthenticationProvider authenticationProvider = new FakeAuthenticationProvider();

    /**
     * Frontend security configuration
     */
    @Configuration
    @Order(2)
    public static class FrontendSecurityConfiguration extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authenticationProvider(authenticationProvider)
                .authorizeRequests()
                    .antMatchers("/resources/**").permitAll()
                    .anyRequest()
                    .hasRole("USER")
                    .and()
                .formLogin()
                    .loginPage( "/login")
                    .permitAll()
                .defaultSuccessUrl("/", true);

        }
    }

    /**
     * Backend security configuration
     */
    @Configuration
    @Order(1)
    public static class BackendSecurityConfiguration extends WebSecurityConfigurerAdapter {
        @Autowired
        private String backendUrl;

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.antMatcher(backendUrl + "**").authenticationProvider(authenticationProvider)
                .authorizeRequests()
                    .anyRequest()
                    .hasRole("ADMIN")
                    .and()
                .formLogin()
                    .loginPage(backendUrl + "login")
                    .permitAll()
                .defaultSuccessUrl(backendUrl, true);
        }
    }

}

而Java为它编译了三个class文件:SecurityConfig$FrontendSecurityConfiguration.class
安全配置$BackendSecurityConfiguration.class
SecurityConfig.class

但是 eclipse 只编译了一个文件 SecurityConfig.class 并且一切正常。

有人知道怎么解决吗？

Answer 1

看来我已经解决了这个问题。刚刚为顶级 SecurityConfig 添加了 @Configuration 注释。
