定时任务xxl-job国产化改造，适配磐维数据库（PostgreSQL）

前言

因公司要求系统需要全面国产化改造，其中也涉及到定时任务xxl-job的改造。

使用的xxl-job版本为：2.5.0

一、修改配置

1、修改pom.xml，引入postgresql组件

+               <dependency>
+                       <groupId>org.postgresql</groupId>
+                       <artifactId>postgresql</artifactId>
+                       <version>42.7.4</version>
+               </dependency>

2、修改application，删除mysql配置，增加postgresql配置

-### xxl-job, datasource
-spring.datasource.url=jdbc:mysql://127.0.0.1:3306/xxl_job?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai
-spring.datasource.username=root
-spring.datasource.password=root_pwd
-spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
-### datasource-poolspring.datasource.type=com.zaxxer.hikari.HikariDataSourcespring.datasource.hikari.minimum-idle=10

+# spring.datasource.hikari.schema=xxl_job

二、修改SQL，适配postgresql

1、文件路径：xxl-job-admin/src/main/resources/mybatis-mapper/XxlJobGroupMapper.xml

-               INSERT INTO xxl_job_group ( `app_name`, `title`, `address_type`, `address_list`, `update_time`)
+               INSERT INTO xxl_job_group ( app_name, title, address_type, address_list, update_time)

-               SET `app_name` = #{appname},
-                       `title` = #{title},
-                       `address_type` = #{addressType},
-                       `address_list` = #{addressList},
-                       `update_time` = #{updateTime}
+               SET app_name = #{appname},
+                       title = #{title},
+                       address_type = #{addressType},
+                       address_list = #{addressList},
+                       update_time = #{updateTime}

2、文件路径：xxl-job-admin/src/main/resources/mybatis-mapper/XxlJobLogGlueMapper.xml

        <insert id="save" parameterType="com.xxl.job.admin.core.model.XxlJobLogGlue" useGeneratedKeys="true" keyProperty="id" >INSERT INTO xxl_job_logglue (
-                       `job_id`,
-                       `glue_type`,
-                       `glue_source`,
-                       `glue_remark`,
-                       `add_time`,
-                       `update_time`
+                       job_id,^M
+                       glue_type,^M
+                       glue_source,^M
+                       glue_remark,^M
+                       add_time, ^M
+                       update_time^M) VALUES (#{jobId},#{glueType},

                WHERE id NOT in(SELECT id FROM(SELECT id FROM xxl_job_logglue
-                               WHERE `job_id` = #{jobId}
+                               WHERE job_id = #{jobId}^MORDER BY update_time descLIMIT 0, #{limit}) t1
-               ) AND `job_id` = #{jobId}
+               ) AND job_id = #{jobId}

        <delete id="deleteByJobId" parameterType="java.lang.Integer" >DELETE FROM xxl_job_logglue
-               WHERE `job_id` = #{jobId}
+               WHERE job_id = #{jobId}^M</delete>

3、xxl-job-admin/src/main/resources/mybatis-mapper/XxlJobLogMapper.xml

总结

因为公司要求系统国产化，所以得把定时任务xxl-job改造适配磐维数据库，大体步骤如下。

1、修改配置。

2、修改SQL，适配postgresql。

最后因本人能力有限，有什么不对的地方望各位大佬指出好让我改进，多多包含，谢谢大家。
