public class WebSphereDataSourceAdapter
extends IsolationLevelDataSourceAdapter
```
DataSource implementation that delegates all calls to a WebSphere target DataSource, typically obtained from JNDI, applying a current isolation level and/or current user credentials to every Connection obtained from it.
Uses IBM-specific API to get a JDBC Connection with a specific isolation level (and read-only flag) from a WebSphere DataSource (IBM code example). Supports the transaction-specific isolation level exposed by TransactionSynchronizationManager.getCurrentTransactionIsolationLevel(). It's also possible to specify a default isolation level, to be applied when the current Spring-managed transaction does not define a specific isolation level.
Usage example, defining the target DataSource as an inner-bean JNDI lookup (of course, you can link to any WebSphere DataSource through a bean reference):
```
 <bean id="myDataSource" class="org.springframework.jdbc.datasource.WebSphereDataSourceAdapter">
   <property name="targetDataSource">
     <bean class="org.springframework.jndi.JndiObjectFactoryBean">
       <property name="jndiName" value="jdbc/myds"/>
     </bean>
   </property>
 </bean>
```

  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    Checks that the specified 'targetDataSource' actually is a WebSphere WSDataSource.
    指定者:
    afterPropertiesSet 在接口中 InitializingBean
    覆盖:
    afterPropertiesSet 在类中 DelegatingDataSource
  - doGetConnection
```
protected Connection doGetConnection(String username,
                                     String password)
                              throws SQLException
```
    Builds a WebSphere JDBCConnectionSpec object for the current settings and calls WSDataSource.getConnection(JDBCConnectionSpec).
    覆盖:
    doGetConnection 在类中 IsolationLevelDataSourceAdapter
    参数:
    username - the username to use
    password - the password to use
    返回:
    the Connection
    抛出:
    SQLException

    createConnectionSpec(java.lang.Integer, java.lang.Boolean, java.lang.String, java.lang.String), com.ibm.websphere.rsadapter.WSDataSource#getConnection(com.ibm.websphere.rsadapter.JDBCConnectionSpec)

                               throws SQLException
```
    Create a WebSphere JDBCConnectionSpec object for the given characteristics.
    The default implementation uses reflection to apply the given settings. Can be overridden in subclasses to customize the JDBCConnectionSpec object (JDBCConnectionSpec javadoc; IBM developerWorks article).
    参数:
    isolationLevel - the isolation level to apply (or null if none)
    readOnlyFlag - the read-only flag to apply (or null if none)
    username - the username to apply (null or empty indicates the default)
    password - the password to apply (may be null or empty)
    抛出:
    SQLException - if thrown by JDBCConnectionSpec API methods
