spring3 ibatis2.x multiple datasource

Question

我使用spring ibatis連接Oracle多用戶空間。

看起來像用戶A，用戶B，用戶系統。

用戶系統始終使用。其他用戶，而在任務（線程）調度研究

spring.xml

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" 
destroy-method="close"> 
    <property name="driverClassName" value="${jdbc.driverClassName}" /> 
    <property name="url" value="${jdbc.url}" /> 
    <property name="username" value="System" /> 
    <property name="password" value="system" /> 
</bean> 

<bean id="dataSource2" class="org.apache.commons.dbcp.BasicDataSource" 
destroy-method="close"> 
    <property name="driverClassName" value="${jdbc.driverClassName}" /> 
    <property name="url" value="${jdbc.url}" /> 
    <property name="username" value="A" /> 
    <property name="password" value="a" /> 
</bean> 

    <bean id="dataSource3" class="org.apache.commons.dbcp.BasicDataSource" 
destroy-method="close"> 
    <property name="driverClassName" value="${jdbc.driverClassName}" /> 
    <property name="url" value="${jdbc.url}" /> 
    <property name="username" value="B" /> 
    <property name="password" value="b" /> 
</bean> 

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> 
    <property name="configLocation" value="classpath:SqlMapConfig.xml" /> 
    <property name="dataSource" ref="dataSource" /> 
</bean> 
<bean id="sqlMapClient1" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> 
    <property name="configLocation" value="classpath:SqlMapConfig.xml" /> 
    <property name="dataSource" ref="dataSource2" /> 
</bean> 

<bean id="sqlMapClient2" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> 
    <property name="configLocation" value="classpath:SqlMapConfig.xml" /> 
    <property name="dataSource" ref="dataSource3" /> 
</bean> 

在道：

public class BaseDao extends SqlMapClientDaoSupport { 
Logger log = Logger.getLogger(getClass()); 

@Resource(name = "sqlMapClient") 
private SqlMapClient sqlMapClient; 


@PostConstruct 
public void initSqlMapClient() { 
    super.setSqlMapClient(sqlMapClient); 
} 
    } 

    public class UserDao extends BaseDao { 
     public void test() 
     { 
      this.getSqlMapClientTemplate().queryForObject("...."); 
     } 
    } 

任務：在taskJob我想調度研究其他datasorce。如何實現它？

public class TaskJob { 

      //@Autowired 
      //UserDao userDao; 
      public void test(){ 
       //to get other sqlmapclient in UserDao 
       userDao.test();//for User A,User B,User .... 
      } 

} 

Answer 1

你不能這樣做，使用SqlMapClientDaoSupport。如果你沒有使用SqlMapClientDaoSupport，那麼下面的解決方案就足夠了。

MapClientFactoryBean不應該有數據源

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> 
    <property name="configLocation" value="classpath:SqlMapConfig.xml" /> 
</bean> 

有兩臺UserDAO的（每個數據源）

<bean id = "userDAO" class = "com.xxxx.UserDAO"> 
    <property name="dataSource" ref="dataSource" /> 
     <property name="sqlMapClient" ref = "sqlMapClient"> 
<bean id = "userDAO1" class = "com.xxxx.UserDAO"> 
    <property name="dataSource2" ref="dataSource" /> 
     <property name="sqlMapClient" ref = "sqlMapClient"> 
</bean>

不可能對代碼進行測試自己。請嘗試。
