我尝试在我的 Spring Security 配置中注册多个过滤器，但是我总是遇到同样的异常:

04-Nov-2015 14:35:23.792 WARNING [RMI TCP Connection(3)-127.0.0.1] org.springframework.web.context.support.AnnotationConfigWebApplicationContext.refresh Exception encountered during context initialization - cancelling refresh attempt org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration': Injection of autowired dependencies failed; nested exception is java.lang.IllegalStateException: @Order on WebSecurityConfigurers must be unique. Order of 100 was already used, so it cannot be used on com.payment21.webapp.MultiHttpSecurityConfig$ApiWebSecurityConfigurationAdapter$$EnhancerBySpringCGLIB$$35c79fe4@1d381684 too.

由于我自己的尝试没有成功，我尝试了 完全相同的代码，如 Spring Security reference 中所示:

@EnableWebSecurity
public class MultiHttpSecurityConfig {
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) { 
        auth
            .inMemoryAuthentication()
                .withUser("user").password("password").roles("USER").and()
                .withUser("admin").password("password").roles("USER", "ADMIN");
    }

    @Configuration
    @Order(1)                                                        
    public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
        protected void configure(HttpSecurity http) throws Exception {
            http
                .antMatcher("/api/**")                               
                .authorizeRequests()
                    .anyRequest().hasRole("ADMIN")
                    .and()
                .httpBasic();
        }
    }

    @Configuration                                                   
    public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                .authorizeRequests()
                    .anyRequest().authenticated()
                    .and()
                .formLogin();
        }
    }
}

为了隔离错误，我尝试用基于 Java 的方法替换 web.xml，但它也不起作用。不知道怎么回事，是不是文档错了？我的应用程序中的某些内容会与配置混淆吗？系统正常启动，除非我注册第二个 WebSecurityConfigAdapter。

这些是我的依赖项:

compile 'org.springframework:spring-webmvc:4.2.2.RELEASE'
compile 'org.springframework:spring-messaging:4.2.2.RELEASE'
compile 'org.springframework:spring-websocket:4.2.2.RELEASE'
compile 'org.springframework:spring-aop:4.2.2.RELEASE'
compile'javax.servlet:javax.servlet-api:3.0.1'
compile 'org.springframework.security:spring-security-web:4.0.3.RELEASE'
compile 'org.springframework.security:spring-security-config:4.0.3.RELEASE'

最佳答案

也许您已经使用 @EnableWebSecurity 注释对另一个类进行了注释。请注意，只有一个类可以实现此注解。希望对您有所帮助!
