druid 1.2.22 的 DruidDataSourceAutoConfigure 改动导致与 dynamic-datasource 不兼容
duird 1.2.22 之前的版本，DruidDataSourceAutoConfigure 定义了 DataSource Bean，该Bean定义会被 dynamic-datasource 的 DataSource Bean覆盖，所以没有问题。
public class DruidDataSourceAutoConfigure {
private static final Logger LOGGER = LoggerFactory.getLogger(DruidDataSourceAutoConfigure.class);
/**
* Not setting initMethod of annotation {@code @Bean} is to avoid failure when inspecting
* the bean definition at the build time. The {@link DruidDataSource#init()} will be called
* at the end of {@link DruidDataSourceWrapper#afterPropertiesSet()}.
*
* @return druid data source wrapper
*/
@Bean
@ConditionalOnMissingBean
public DataSource dataSource() {
LOGGER.info("Init DruidDataSource");
return new DruidDataSourceWrapper();
}
}
但 duird 1.2.22 的 DruidDataSourceAutoConfigure 把 Bean 类型改为了 DruidDataSourceWrapper，dynamic-datasource 不能覆盖这个Bean定义。所以，由于没有相应的druid配置，导致加载 DruidDataSourceWrapper Bean 失败。
public class DruidDataSourceAutoConfigure {
private static final Logger LOGGER = LoggerFactory.getLogger(DruidDataSourceAutoConfigure.class);
/**
* Not setting initMethod of annotation {@code @Bean} is to avoid failure when inspecting
* the bean definition at the build time. The {@link DruidDataSource#init()} will be called
* at the end of {@link DruidDataSourceWrapper#afterPropertiesSet()}.
*
* @return druid data source wrapper
*/
@Bean
@ConditionalOnMissingBean
public DruidDataSourceWrapper dataSource() {
LOGGER.info("Init DruidDataSource");
return new DruidDataSourceWrapper();
}
}
我的druid版本是1.1.22 ， dynamic 版本是3.2.0 下面是我的yaml配置
spring:
autoconfigure:
exclude: com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure
datasource:
dynamic:
primary: test1
datasource:
test1:
url: jdbc:mysql://192.168.1.1:5/test1
username: root
password: root
test2:
url: jdbc:mysql://192.168.1.1:5/test2
username: root
password: root
当我启动时，会抛出如下错误
***************************
APPLICATION FAILED TO START
***************************
Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine suitable jdbc url
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (the profiles test are currently active).
Disconnected from the target VM, address: '127.0.0.1:14021', transport: 'socket'
Process finished with exit code 1
我将dynamic 的版本降到了2.5.6，再次启动可以正常启动，我不知道跟这个话题有没有关系，但是我想知道为什么会导致出现这个情况，感谢
启动类加个注解也可以暂时解决
@SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)
问题一样，能否迭代？
@Umenezumi 联系 druid 哦。 我这边不会更改
看了下 druid 那边，确实不需要您修改，他们会在下一个版本解决这个问题，劳烦您到时更新 Readme ，避免大家使用 1.2.22 版本
