springboot使用jta-atomikos搭建分布式事物、多数据源
作者:互联网
不多说,上代码:
1:引入包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jta-atomikos</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
2:配置application.yml
spring:
datasource:
atomikos:
dbcms:
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/zbox_cms?useUnicode=true&characterEncoding=utf8
minPoolSize: 5
maxPoolSize: 25
maxLifetime : 20000
borrowConnectionTimeout : 30
loginTimeout : 30
maintenanceInterval : 60
maxIdleTime : 60
dbuser:
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/zbox_user?useUnicode=true&characterEncoding=utf8
minPoolSize: 5
maxPoolSize: 25
maxLifetime : 20000
borrowConnectionTimeout : 30
loginTimeout : 30
maintenanceInterval : 60
maxIdleTime : 60
3:配置数据源实体和config

说明:
sourceconfig类需要扫描到准确的mapper,在分包的时候一定记得包内尽量不要出现多个数据源的mapper
出现问题,多看看自己扫描的包是否有问题。
启动失败,有可能是扫描出问题,看看启动的日志。
