SpringBoot的filter、listener、interceptor、AOP

SpringBoot下的Filter

SpringBoot下的Listener

##SpringBoot下的Interceptor

拦截器
需要继承类型HandlerInterceptorAdapter
并在@Configuration配置类型中配置拦截器

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.StringUtils;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

public class PermissionInterceptor extends HandlerInterceptorAdapter {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
		throws Exception {
	return super.preHandle(request, response, handler);
}

}

	@Bean
	public PermissionInterceptor permissionInterceptor() {
		return new PermissionInterceptor();
	}
@Override
public void addInterceptors(InterceptorRegistry registry) {
	registry.addInterceptor(permissionInterceptor()) // 权限拦截器
			.addPathPatterns("/**") // 拦截所有
			.excludePathPatterns("/callback/**") // 排除拦截回调
			.excludePathPatterns("/") // 排除拦截默认
			.excludePathPatterns("/css/**") // 排除拦截静态资源
			.excludePathPatterns("/js/**") // 排除拦截静态资源
			.excludePathPatterns("/favicon.ico"); // 排除拦截静态资源
	super.addInterceptors(registry);
