SpringBoot-拦截器的使用

• 使用注解 @Configuration 配置拦截器
• 继承 WebMvcConfigurerAdapter
• 重写 addInterceptors 添加需要的拦截器地址
• 具体实现

package com.worksplaza.edu.online.configuration;

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 MyWebMvcConfigurer implements WebMvcConfigurer {

    @Bean
    public SessionInterceptor sessionInterceptor() {
        return new SessionInterceptor();
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(sessionInterceptor())
                .addPathPatterns("/**").excludePathPatterns("/crossdomain.xml")
                .excludePathPatterns("/weixin/")
                .excludePathPatterns("/wechat/notify");
    }  
    
}
