一种存储介质可扩展的持久化重试方案
- 增加pom依赖
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>easy-retry-memory-starter</artifactId>
<version>${last-version}</version>
</dependency>- 在application.properties增加配置
spring.easyretry.memory.enabled = true
- 在需要重试的方法上增加
@EasyRetryable注解
public class MemoryUserService {
@EasyRetryable
public User getUserById(Long userId){
return new User();
}
}- 增加pom依赖
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>easy-retry-mybatis-starter</artifactId>
<version>${last-version}</version>
</dependency>- 在application.properties增加配置
spring.easyretry.mybatis.enabled = true
- 声明
javax.sql.DataSource的Bean实例，参考下面例子（以druid连接池为例）
@Bean(name = "easyRetryMybatisDataSource", initMethod = "init", destroyMethod = "close")
public DataSource easyRetryMybatisDataSource() {
DruidDataSource tds = new DruidDataSource();
tds.setUrl("");
tds.setUsername("");
tds.setPassword("");
...
return tds;
}
- 新增持久化表
CREATE TABLE `easy_retry_task` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT COMMENT '主键',
`gmt_create` datetime NOT NULL COMMENT '创建时间',
`gmt_modified` datetime NOT NULL COMMENT '修改时间',
`sharding` varchar(64) DEFAULT NULL COMMENT '数据库分片字段',
`biz_id` varchar(64) DEFAULT NULL COMMENT '业务id',
`executor_name` varchar(512) NOT NULL COMMENT '执行名称',
`executor_method_name` varchar(512) NOT NULL COMMENT '执行方法名称',
`retry_status` tinyint(4) NOT NULL COMMENT '重试状态',
`args_str` varchar(7168) DEFAULT NULL COMMENT '执行方法参数',
`ext_attrs` varchar(3000) DEFAULT NULL COMMENT '扩展字段',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8 COMMENT='easy_retry_task'
;
- 在需要重试的方法上增加@EasyRetryable注解
public class MybatisUserService {
@EasyRetryable
public User getUserById(Long userId){
return new User();
