Spring mvc 未从AppConfig加载SpringBeans xml

我正在尝试将所有配置从xml移动到基于注释的

`web.xml'文件是

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = { "jbr.springmvc" })
public class AppConfig extends WebMvcConfigurerAdapter {
  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    System.out.println("inside addResourceHandlers");
    registry.addResourceHandler("/resources/**")
        .addResourceLocations("classpath:/resources/config/");
  }

我在src/main/resources/config文件夹下有

user bean.xml

（maven web项目，视图：eclipse中的Navigator）

有人能指出这里出了什么问题吗？

使用@ImportResource将Spring XML配置文件导入@configuration

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = { "jbr.springmvc" })
@ImportResource("classpath:/config/user-bean.xml")
public class AppConfig extends WebMvcConfigurerAdapter {
  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    System.out.println("inside addResourceHandlers");
    registry.addResourceHandler("/resources/**")
        .addResourceLocations("classpath:/resources/config/");
  }
}

您需要将user-bean.xml导入配置类@importThanks很多，我尝试了@ImportResource（“classpath*：user beans.xml”）并对我有效。
