# 动态数据源JTA实现 (atomikos)
|
||
使用atomikos实现动态数据源事务管理
|
||
|
||
# 数据源配置
|
||
默认数据源配置,使用spring的jta配置即可:
|
||
```yaml
|
||
spring:
|
||
jta:
|
||
status: true
|
||
atomikos:
|
||
datasource:
|
||
xa-data-source-class-name: com.alibaba.druid.pool.xa.DruidXADataSource
|
||
xa-properties:
|
||
url : jdbc:h2:mem:core;DB_CLOSE_ON_EXIT=FALSE
|
||
username : sa
|
||
password :
|
||
max-pool-size: 20
|
||
borrow-connection-timeout: 1000
|
||
connectionfactory:
|
||
max-pool-size: 20
|
||
local-transaction-mode: true
|
||
```
|
||
|
||
动态数据源配置,默认提供一个 ``InMemoryAtomikosDataSourceRepository``,在application.yml 中进行配置即可:
|
||
```yaml
|
||
hsweb:
|
||
datasource:
|
||
jta:
|
||
test_ds: # 数据源ID
|
||
xa-data-source-class-name: com.alibaba.druid.pool.xa.DruidXADataSource
|
||
xa-properties: # 数据源的配置属性
|
||
url: jdbc:h2:mem:test;DB_CLOSE_ON_EXIT=FALSE
|
||
username: sa
|
||
password:
|
||
max-pool-size: 20
|
||
borrow-connection-timeout: 1000
|
||
test_ds2: # 数据源ID
|
||
xa-data-source-class-name: com.alibaba.druid.pool.xa.DruidXADataSource
|
||
xa-properties: # 数据源的配置属性
|
||
url: jdbc:mysql://localhost:3306/hsweb?pinGlobalTxToPhysicalConnection=true&useSSL=false&useUnicode=true&characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false
|
||
# url: jdbc:h2:mem:test2;DB_CLOSE_ON_EXIT=FALSE
|
||
username: root
|
||
password: "123456" # 纯数字密码要加上双引号，不然启动会报Cannot initialize AtomikosDataSourceBean
|
||
max-pool-size: 20
|
||
borrow-connection-timeout: 1000
|
||
init-timeout: 20
|
||
```
|
||
|
||
自定义,将数据源配置放到数据库中,实现 ``DynamicDataSourceConfigRepository<AtomikosDataSourceConfig>`` 接口并注入到spring容器即可
