有网友反应，看了后，还是不知道怎么做spring的unit test，下面把 自己写的抽象类给出来，应该容易懂了。

public abstract class AbstractTest extends AbstractTransactionalDataSourceSpringContextTests{

 public String[] getConfigLocations() {   String[] config= new String[]{"frame-applicationContext.xml"};    return config; } protected RoleInfoService roleInfoService; protected OperationInfoService operationInfoService; protected UserBaseInfoService userService; protected void onSetUpInTransaction() throws Exception {         super.onSetUpInTransaction();         //this.setPopulateProtectedVariables(true);         roleInfoService = (RoleInfoService) this.applicationContext.getBean("roleInfoService");        operationInfoService=(OperationInfoService)this.applicationContext.getBean("operationInfoService");        userService = (UserBaseInfoService) this.applicationContext.getBean("userBaseInfoService");

    }

    protected void onTearDownInTransaction() {

     roleInfoService = null;     operationInfoService=null;     userService = null;    }}

每个service的独立的unit test，只要继承该类就可以了。
