xml文件中的Springboot多數據源

Question

我想用Springboot創建restService。但我想要一個可配置的數據源，我希望能夠在需要時添加新的數據源。但是我有這樣的例外：

> No qualifying bean of type 'javax.sql.DataSource' available: expected 
> single matching bean but found 2 

而且我使用此代碼：

<bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
     <property name="showSql" value="true"/> 
     <property name="generateDdl" value="true"/> 
     <property name="database" value="ORACLE"/> 
    </bean> 

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClassName" value="oracle.jdbc.OracleDriver"/> 
     <property name="url" value="jdbc:oracle:thin:@localhost:9999:TEST"/> 
     <property name="username" value="test"/> 
     <property name="password" value="test"/> 
    </bean> 

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
     <property name="dataSource" ref="dataSource"/> 
     <property name="jpaVendorAdapter" ref="jpaVendorAdapter"/> 
     <!-- spring based scanning for entity classes--> 
     <property name="packagesToScan" value="com.orange.aurore.model.entity"/> 
     <property name="persistenceUnitName" value="msPersistenceUnit" /> 
</bean> 

<bean id="controllerService" class="...controller.impl.ControllerServiceImpl"> 
    <property name="entityManager" ref="entityManagerFactory" /> 
    <property name="dataSource" ref="dataSource"/> 
</bean> 

和：

<bean id="dataSource2" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
      <property name="driverClassName" value="oracle.jdbc.OracleDriver"/> 
      <property name="url" value="jdbc:oracle:thin:@localhost:9999:TEST"/> 
      <property name="username" value="test2"/> 
      <property name="password" value="test2"/> 
     </bean> 

    <bean id="entityManagerFactory2" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
      <property name="dataSource" ref="dataSource2"/> 
      <property name="jpaVendorAdapter" ref="jpaVendorAdapter"/> 
      <!-- spring based scanning for entity classes--> 
      <property name="packagesToScan" value="com.orange.aurore.model.entity"/> 
      <property name="persistenceUnitName" value="msPersistenceUnit2" /> 
    </bean> 

    <bean id="controllerService2" class="...controller.impl.ControllerServiceImpl"> 
     <property name="entityManager" ref="entityManagerFactory2" /> 
     <property name="dataSource" ref="dataSource2"/> 
    </bean> 

和Java代碼：

public void setEntityManager(final HibernateEntityManagerFactory entityManager) { 
    final RepositoryFactorySupport factorySupport = new JpaRepositoryFactory(entityManager.createEntityManager()); 

    controlRepository = factorySupport.getRepository(ObjControlRepository.class); 

謝謝你的幫助。

這是一個愚蠢的錯誤，我爲我的兩個配置之一添加primary =「true」。
