春季安全性：NoSuchBeanDefinitionException：找不到类型为[org.springframework.security.config.annotation.ObjectPostProcessor]的合格Bean

我正在尝试在我的rest应用程序中添加spring-
security。我按照Spring网站上的教程（https://spring.io/guides/tutorials/spring-security-
and-angular-js/）进行了操作，但是这里使用的是我不想使用的spring-boot组件。 ，也许问题就在这里。

我的安全配置在这里：

@Configuration@Order(2147483636)public class SecurityConfiguration extends WebSecurityConfigurerAdapter {@Overrideprotected void configure(HttpSecurity http) throws Exception {    http.httpBasic().and().authorizeRequests()            .antMatchers("/rest", "/").permitAll().anyRequest()            .authenticated().and().csrf()            .csrfTokenRepository(csrfTokenRepository()).and()            .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);}private Filter csrfHeaderFilter() {    return new OncePerRequestFilter() {        @Override        protected void doFilterInternal(HttpServletRequest request,                                        HttpServletResponse response, FilterChain filterChain)                throws ServletException, IOException {            CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class                    .getName());            if (csrf != null) {                Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");                String token = csrf.getToken();                if (cookie == null || token != null                        && !token.equals(cookie.getValue())) {                    cookie = new Cookie("XSRF-TOKEN", token);                    cookie.setPath("/");                    response.addCookie(cookie);                }            }            filterChain.doFilter(request, response);        }    };}private CsrfTokenRepository csrfTokenRepository() {    HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();    repository.setHeaderName("X-XSRF-TOKEN");    return repository;    }}

答案1

问题是您@EnableWebSecurity在SecurityConfiguration类上没有注释。

这将由Spring-boot自动添加，但是由于您选择不使用Spring-boot， 因此需要手动进行此操作 。

在 AppApplicationService 类上的 @Service , 我的代码中引入了 alibaba 的 Service 类: import  com.alibaba.dubbo.config.annotation.Service; 

实际应该引入 Spring 的 Service 类: import org.springframework.stereotype.Service;

修改后，问题消失，看来问题还要多方面考虑解决啊！

问题的根源是出现bean名称重复

原因：

1.两个bean名称重复，spring扫描无法创建bean对象（有时候会与引入的第三方的jar包中的bean名称重复）；

2.target中有缓存导致，Maven项目clean下再编译
