想了解SpringBoot中定制异常页面的实现方法的相关内容吗,Asurplus、在本文为您仔细讲解SpringBoot 定制异常页面的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:SpringBoot,定制异常页面,SpringBoot,,异常页面,下面大家一起来学习吧。

定制异常页面,可以避免用户产生恐慌心理,使得产品有更好的用户体验。今天来学习在 SpringBoot 中如何定制开发异常页面

一、历史回顾

在 SpringMVC 年代,我们的异常页面一般配置在 web.xml 文件中,如下:

<!-- 配置404页面 -->
<error-page>
   <error-code>404</error-code>
   <location>/error/404.html</location>
 </error-page>

这里我们指定了异常请求状态码 404,然后配置了 404 异常请求的页面地址,这就意味着如果某一个请求发生了 404 异常,则会出现 404.html 界面

二、SpringBoot中配置

1、默认异常页面


这是 SpringBoot 中默认的异常页面,返回的是一堆异常信息和异常状态码,那用户固然是看不懂这些信息的,容易使得用户产生恐慌的心里,从而影响产品的用户体验

2、定制异常页面

SpringBoot 中定制异常页面非常简单,我们需要一个配置文件 ExceptionPageConfig.java

import org.springframework.boot.web.server.ConfigurableWebServerFactory;
import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;

/**
 * 统一异常页面处理
 *
 * @Author Lizhou
 **/
@Configuration
public class ExceptionPageConfig {

  /**
   * SpringBoot2.0以上版本
   * WebServerFactoryCustomizer代替之前版本的EmbeddedWebServerFactoryCustomizerAutoConfiguration
   *
   * @return
   */
  @Bean
  public WebServerFactoryCustomizer<ConfigurableWebServerFactory> webServerFactoryCustomizer() {
    return (container -> {
      ErrorPage error400Page = new ErrorPage(HttpStatus.BAD_REQUEST, "/400");
      ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/404");
      ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/500");
      container.addErrorPages(error400Page, error404Page, error500Page);
    });
  }
}

可以看出,这里我们配置了 400、404、500 三种异常页面,然后我们需要编写 API 请求异常页面 SysExceptionController.java

import com.zyxx.common.utils.PasswordUtils;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.apache.shiro.SecurityUtils;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

/**
 * <p>
 * 前端控制器
 * </p>
 *
 * @author lizhou
 * @since 2020-07-15
 **/
@Api(tags = "后台管理端--异常处理")
@Controller
public class SysExceptionController {

  @ApiOperation(value = "请求400页面", notes = "请求400页面")
  @GetMapping("400")
  public String badRequest() {
    return "sys/exception/400";
  }

  @ApiOperation(value = "请求404页面", notes = "请求404页面")
  @GetMapping("404")
  public String notFound() {
    return "sys/exception/404";
  }

  @ApiOperation(value = "请求500页面", notes = "请求500页面")
  @GetMapping("500")
  public String serverError() {
    return "sys/exception/500";
  }
}

API 写好,下面我们就需要开发异常页面的展示信息了,这里贴一张页面吧,404.html

import com.zyxx.common.utils.PasswordUtils;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.apache.shiro.SecurityUtils;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

/**
 * <p>
 * 前端控制器
 * </p>
 *
 * @author lizhou
 * @since 2020-07-15
 **/
@Api(tags = "后台管理端--异常处理")
@Controller
public class SysExceptionController {

  @ApiOperation(value = "请求400页面", notes = "请求400页面")
  @GetMapping("400")
  public String badRequest() {
    return "sys/exception/400";
  }

  @ApiOperation(value = "请求404页面", notes = "请求404页面")
  @GetMapping("404")
  public String notFound() {
    return "sys/exception/404";
  }

  @ApiOperation(value = "请求500页面", notes = "请求500页面")
  @GetMapping("500")
  public String serverError() {
    return "sys/exception/500";
  }
}

然后所需要的 exception.css

三、测试

项目启动后,我们访问一个并不存在的 API


那,通过访问一个项目中并不存在的 API,得到 404 页面,页面可以提示一些友好的文字,从而安抚用户紧张的心理,其实也是一个不错的选择吧
