springboot拦截器注入service为null【踩坑记录】

以下这种方式能注册拦截器，也能使用，但是获取到注入的service 是null。

我的拦截器类

@Component
public class LesionInterceptor implements HandlerInterceptor {

	@Autowired
	private IOrganizationService organizationService;
	
	// TODO 其他代码
}

配置类

@Configuration
public class MyWebMvcConfig implements WebMvcConfigurer {

	@Bean
	public MyWebMvcConfig getMyWebMvcConfig() {
		MyWebMvcConfig myWebMvcConfig = new MyWebMvcConfig() {
			@Override
			public void addViewControllers(ViewControllerRegistry registry) {
				// registry.addViewController("/").setViewName("alogin");
				// registry.addViewController("/login").setViewName("alogin");
				// registry.addViewController("/main.html").setViewName("dashboard");
			}

			// 注册拦截器
			@Override
			public void addInterceptors(InterceptorRegistry registry) {
				registry.addInterceptor(new LesionInterceptor())
						.addPathPatterns("
@Configuration
public class MyWebMvcConfig implements WebMvcConfigurer {

	//这里的LesionInterceptor 是上面定义的拦截器的类型
	@Bean
	public LesionInterceptor MyWebMvcConfig() {
//		MyWebMvcConfig myWebMvcConfig = new MyWebMvcConfig() {
//			@Override
//			public void addViewControllers(ViewControllerRegistry registry) {
//				// registry.addViewController("/").setViewName("alogin");
//				// registry.addViewController("/login").setViewName("alogin");
//				// registry.addViewController("/main.html").setViewName("dashboard");
//			}
//
//			// 注册拦截器
//			@Override
//			public void addInterceptors(InterceptorRegistry registry) {
//				registry.addInterceptor(new LesionInterceptor())
//						.addPathPatterns("/**")
//						.excludePathPatterns("/login", "/swagger", "/",
//								"/swagger-resources/**", "/webjars/**",
//								"/v2/**", "/swagger-ui.html/**");
//				super.addInterceptors(registry);
//			}
//		};
		return new LesionInterceptor();
	}

	@Override
	public void addInterceptors(InterceptorRegistry registry) {
		//多个拦截器组成一个拦截器链
		// addPathPatterns用于添加拦截规则
		// excludePathPatterns用户排除拦截
		//对来自/** 全路径请求进行拦截
		registry.addInterceptor(MyWebMvcConfig()).addPathPatterns("/**");

	}

}

至此解决，
还有一种方式就是继承 WebMvcConfigurerAdapter，但是这种方式已经过时。可参考 https://blog.csdn.net/wmh13262227870/article/details/77005920
