1. 报错信息
系统错误，错误信息：org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'defaultTx' is expected to be of type 'org.springframework.transaction.PlatformTransactionManager' but was actually of type 'org.springframework.transaction.support.TransactionTemplate'2.2. 原因
使用了自定义的事务模板，样例代码如下
@Bean(name = TransactionConfig.DEFAULT_TX)
@Primary
public TransactionTemplate transaction(@Qualifier("firstDataSource") DataSource firstDataSource) {
DataSourceTransactionManager dataSourceTransactionManager = new DataSourceTransactionManager(firstDataSource);
return new TransactionTemplate(dataSourceTransactionManager);
}
@Bean(name = TransactionConfig.SECOND_TX)
public TransactionTemplate secondTransaction(@Qualifier("secondDataSource") DataSource secondDataScoure) {
DataSourceTransactionManager dataSourceTransactionManager = new DataSourceTransactionManager(secondDataScoure);
return new TransactionTemplate(dataSourceTransactionManager);
}
3. 解决方法
@Bean(name = DEFAULT_TX)
@Primary
public DataSourceTransactionManager firstDataSourceTransaction(@Qualifier("firstDataSource") DataSource firstDataSource) {
return new DataSourceTransactionManager(firstDataSource);
}
@Bean(name = SECOND_TX)
public DataSourceTransactionManager secondDataSourceTransaction(@Qualifier("secondDataSource") DataSource secondDataSource) {
return new DataSourceTransactionManager(secondDataSource);
}
