Spring Boot使用-SpringMVC拦截器

可以在Spring Boot项目中配置自定义SpringMVC拦截器

  1. 编写拦截器(实现HandlerInterceptor);
  2. 编写配置类实现 WebMvcConfigurer,在该类中添加各种组件;

具体实现:


import com.myself.interceptor.MyInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class MvcConfig implements WebMvcConfigurer {

    //注册拦截器
    @Bean
    public MyInterceptor myInterceptor(){
        return new MyInterceptor();
    }

    //添加拦截器到spring mvc拦截器链
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(myInterceptor()).addPathPatterns("/*");
    }
}
