十一、使用注解方式注入属性

1.1删除applicationContext中employeeService对于sessionFactory的注入

<bean id="employeeService" class="com.myz.service.imps.EmployeeService">
    </bean>

1.2在employeeService类中增加注解

//当我们给某个属性值增加了@Resource后，spring就会启动byName的方式注入此属性
    @Resource
    private SessionFactory sessionFactory;

1.3启用注解扫描

<!-- 启用注解扫描 -->
    <context:annotation-config />

2.1同理，移除applicationContext中action对于employeeService的注入

<!-- 配置action 而且配置scope可以解决action的单例的问题-->
    <bean name="/login" class="com.myz.web.actions.LoginAction" scope="prototype">
    </bean>

2.2在LoginAction中增加注解

public class LoginAction extends DispatchAction {
    @Resource
    private EmployeeServiceInterface employeeService;
    
    
    public EmployeeServiceInterface getEmployeeService() {
        return employeeService;
    }


    public void setEmployeeService(EmployeeServiceInterface employeeService) {
        this.employeeService = employeeService;
    }

 2.3已经启用了注解扫描的话，就不用再启用了
