我的世界做壁纸的网站,网站要怎么样做排名才上得去,做枸杞的网站,公众号官方其实所有的Filter都是一样的原理
大致流程:
创建一个自定义Filter, 用于拦截所有异常此Filter正常进行后续Filter调用当调用后续Filter时, 如果发生异常, 则委托给HandlerExceptionResolver进行后续处理即可
以sa-token的SaServletFilter为例
首先注册SaToken的过滤器

大致流程:
创建一个自定义Filter, 用于拦截所有异常此Filter正常进行后续Filter调用当调用后续Filter时, 如果发生异常, 则委托给HandlerExceptionResolver进行后续处理即可
以sa-token的SaServletFilter为例
首先注册SaToken的过滤器
package kim.nzxy.demo.config;import cn.dev33.satoken.filter.SaServletFilter;
import cn.dev33.satoken.stp.StpUtil;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;Configuration
public class SaTokenConfig {/*** 注册 [Sa-Token全局过滤器]*/Beanpublic SaServletFilter getSaServletFilter() {return new SaServletFilter().addInclude(/**).addExclude(/favicon.ico, /hello.html).setAuth(obj - StpUtil.checkLogin());}
}其次, 自定义一个自己的过滤器, 优先级设为最高:
package kim.nzxy.demo.filter;import jakarta.servlet.FilterChain;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;
import org.springframework.web.servlet.HandlerExceptionResolver;Component
Order(Ordered.HIGHEST_PRECEDENCE)
public class ExceptionHandlerFilter extends OncePerRequestFilter {private HandlerExceptionResolver resolver;Autowiredpublic void setResolver(Qualifier(handlerExceptionResolver) HandlerExceptionResolver resolver) {this.resolver resolver;}Overrideprotected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) {try {filterChain.doFilter(request, response);} catch (Exception e) {resolver.resolveException(request, response, null, e);}}
}最后, 自定义一个自己的异常拦截器, 这里就直接返回文字格式的异常Message了:
package kim.nzxy.demo.ex;import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;/*** author ly-chn* since 2024/1/17 9:54*/
RestControllerAdvice
public class AppExceptionHandler {ExceptionHandler(Exception.class)public String handler(Exception e) {return Some error happened: e.getMessage();}
}效果如图所示: 完整demo见github
