2.解决方案

2.1 分析报错原因：

xxl-job 执行业务方法新增， mp 自动填充创建者ID 使用了 StpUtil.getLoginIdDefaultNull()，此时是非 web 上下文，所以报错 非 web 上下文无法获取 HttpServletRequest

2.2 解决方案--只需修改 mp 自动填充 creatorId 代码

/** * MybatisPlus 自动填充策略处理器 */@Componentpublic class MybatisPlusHandler implements MetaObjectHandler {    @Override    public void insertFill(MetaObject metaObject) {        // 获取 createTime 属性，如果 createTime 为空，则设置为当前时间        Object createTime = getFieldValByName("createTime", metaObject);        if (createTime == null) {            this.setFieldValByName("createTime", LocalDateTime.now(), metaObject);        }        this.setFieldValByName("ts", LocalDateTime.now(), metaObject);        try {            Object loginId = StpUtil.getLoginIdDefaultNull();            this.setFieldValByName("creatorId", loginId, metaObject);        } catch (Exception e){            // creatorId 为 0 表示是定时任务添加数据            this.setFieldValByName("creatorId", "0", metaObject);        }    }    @Override    public void updateFill(MetaObject metaObject) {        // 属性名        this.setFieldValByName("ts", LocalDateTime.now(), metaObject);    }}
