我使用的是JpaTransactionManager，而不是DataSourceTransactionManager。
JavaDoc http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/orm/jpa/JpaTransactionManager.html
This transaction manager also supports direct DataSource access within a transaction (i.e. plain JDBC pre working with the same DataSource). This allows for mixing services which access JPA and services which use plain JDBC (without being aware of JPA)! Application pre needs to stick to the same simple Connection lookup pattern as with DataSourceTransactionManager (i.e. DataSourceUtils.getConnection(javax.sql.DataSource) or going through a TransactionAwareDataSourceProxy). Note that this requires a vendor-specific JpaDialect to be configured.
在我将jpaVendorAdapter添加到我的entityManagerFactory配置中之后，一切正常，JdbcTemplate查询和MyBatis都按预期在同一事务中运行。基于JavaDoc，我猜jpaDialect应该足够了，但是现在是4点，所以我现在就不尝试了：)
<bean id="entityManagerFactory"> <property name="persistenceUnitName" value="persistenceUnit"/> <property name="dataSource" ref="dataSource"/> <property name="jpaVendorAdapter"> <bean > <property name="showSql" value="true" /> <property name="generateDdl" value="true" /> <property name="databasePlatform" value="org.hibernate.dialect.PostgreSQLDialect" /> </bean> </property></bean>
