Constructor Details

BaseService

public BaseService()

Method Details

init

public void init(org.nutz.dao.Dao dao)

初始化方法，注入Dao对象 通过Resource注解自动注入Dao实例，并设置到父类中

低级(多数据源注意): @Resource(type=Dao.class) 按类型注入——容器中存在多个 Dao Bean 时 会抛 NoUniqueBeanDefinitionException。单数据源工程无影响;多数据源请改用 @Resource(name="xxxDao") 或 @Qualifier 指定具体 Bean

Parameters:

dao - 数据访问对象

getEntityType

public Class<T> getEntityType()

获取实体类型 实现ExtService接口的方法，返回当前服务处理的实体类类型

Specified by:

getEntityType in interface ExtService<T extends Entity>

Returns:

实体类的Class对象
