智能提醒助理系列-jdk8升级到21,springboot2.3升级到3.3

        本系列文章记录“智能提醒助理”产品建设历程,记录实践经验、巩固知识点、锻炼总结能力。

本篇介绍技术栈升级的过程,遇到的问题和解决方案。

一、需求出发点

智能提醒小程序 当前使用的是jdk8,springboot2.3,升级到jdk21和springboot3.3 学习新知识的同时,感受带来的性能提升。

二、实现路径

先了解其他人的升级经验,获取maven 依赖的版本号。

然后就是 报错替换,最最主要的还是servlet包 变动大。

<properties>
    <jdy.version>4.0</jdy.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>21</java.version>

    <mybatis-plus.version>3.5.7</mybatis-plus.version>
    <dynamic-datasource.version>4.3.1</dynamic-datasource.version>
    <pagehelper.boot.version>1.4.7</pagehelper.boot.version>

    <druid.version>1.2.23</druid.version>
    <bitwalker.version>1.19</bitwalker.version>
    <kaptcha.version>2.3.2</kaptcha.version>

    <oshi.version>3.9.1</oshi.version>
    <commons.io.version>2.15.1</commons.io.version>
    <commons.fileupload.version>1.3.3</commons.fileupload.version>
    <commons.beanutils.version>1.9.3</commons.beanutils.version>
    <jsoup.version>1.18.1</jsoup.version>
    <poi.version>3.17</poi.version>
    <velocity.version>1.7</velocity.version>
    <lombok.version>1.18.34</lombok.version>
    <fastjson.version>1.2.83</fastjson.version>
  </properties>

  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>3.3.4</version>
  </parent>

三、实际操作遇到的问题

1、shiro无springboot3.3版本的支持

先参考以上3篇完成后,基本就能跑起来了。

跑起来 遇到的第一个问题就shiro 与springboot3.3.4 不兼容的问题。

调整了多次无果,最后决定把shiro框架卸载掉,重写了shiro部分,过程比预计的难度要低。

2、swagger API 调整较大

API差别较大,修改工作量大,且当前开发人员少,用不上。考虑先卸载掉,后续需要的时候再加上。

3、springboot3.3.4版本 404 请求报错

升级前:

当前访问一个不存在的资源时会返回404,不会抛出异常。

升级后:

会抛出异常:

 [XNIO-1 task-7] ERROR [18d92340fb214056b1e2691fb04aeb36] [c.j.c.c.c.e.GlobalExceptionHandler.handleException-55] - No static resource version.

解决办法:

增加全局异常处理,顺便把其他分类的异常也统一处理下

package com.jdy.common.core.controller.exception;

import com.jdy.common.core.domain.R;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.HttpRequestMethodNotSupportedException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.servlet.resource.NoResourceFoundException;

/**
 * 全局异常处理器
 *
 * @author ruoyi
 */
@RestControllerAdvice
@Slf4j
public class GlobalExceptionHandler {


  /** 404全局异常处理 */
  @ExceptionHandler(NoResourceFoundException.class)
  public R handleException(NoResourceFoundException e) {
    log.error("请求资源不存在:{}",e.getMessage());
    return R.failure("404", "请求资源不存在", "");
  }

  /** 400 无效请求,参数错误 */
  @ExceptionHandler(IllegalArgumentException.class)
  public R handleException(IllegalArgumentException e) {
    log.error("无效请求,参数错误:{}",e.getMessage());
    return R.failure("400", "无效请求,参数错误", "");
  }

  /** 405请求方式不支持 */
  @ExceptionHandler({HttpRequestMethodNotSupportedException.class})
  public R handleException(HttpRequestMethodNotSupportedException e) {
    log.error("请求方式不正确:{}",e.getMessage(), e);
    return R.failure("405", "请求资源不支持" + e.getMethod() + "请求", "");
  }

  /** 500全局异常处理 */
  @ExceptionHandler(Exception.class)
  public R handleException(Exception e) {
    log.error("全局异常:{}",e.getMessage(), e);
    return R.failure("500", "服务器忙", "");
  }

}

 结果展示:

4、pagehelper 分页插件失效

升级前
    <!-- pagehelper 分页插件 -->
    <dependency>
      <groupId>com.github.pagehelper</groupId>
      <artifactId>pagehelper-spring-boot-starter</artifactId>
      <version>1.4.1</version>
    </dependency>

升级后
 <dependency>
      <groupId>com.github.pagehelper</groupId>
      <artifactId>pagehelper-spring-boot-starter</artifactId>
      <version>1.4.7</version>
      <exclusions>
        <exclusion>
          <groupId>com.github.jsqlparser</groupId>
          <artifactId>jsqlparser</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

    <dependency>
      <groupId>com.github.jsqlparser</groupId>
      <artifactId>jsqlparser</artifactId>
      <version>4.5</version>
    </dependency>

需要注意:
第一个参数 要从1开始 而不是0
startPage(page==0 ? 1 : page, size, "id", "DESC");

5、单元测试框架从Junit4升级到了Junit5

org.junit.Test; 升级到了 org.junit.jupiter.api.Test;

升级前:

@RunWith(SpringRunner.class)
@SpringBootTest

升级后:

@RunWith 不再支持。

仅使用 @SpringBootTest 即可

6、容器部署 镜像升级

升级前 11对jdk8是兼容的:
FROM amd64/openjdk:11

升级后:
FROM amd64/openjdk:21-rc-jdk

四、总结

升级后要进行全方面的测试,测试后 还可以通过新老版本并行的方式,观察运行情况,及时调整。
