spring项目中配置MVC拦截器

    

    
    
    
    

    
    
        
         
还有一种方法: 是通过注解配置类的方式拦截,这两种二选其一
 
package com.hwxx.common.web;

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 SpringMebConfig implements WebMvcConfigurer{
	//配置spring mvc拦截器
	@Override
	public void addInterceptors(InterceptorRegistry registry) {
		registry.addInterceptor(new AccessInterceptor())
				.addPathPatterns("/**")
				.excludePathPatterns("/login");  //放行哪个不拦截
	}
}
