注释类型 OrmQuery

@Target(value=TYPE)
 @Retention(value=RUNTIME)
public @interface OrmQuery

对象映射关系,提供一个懒加载方式加载，如果模板sql文件里已经有，则会做合并 并以sql模板里的优先。

@OrmQuery(
value={
        @OrmCondition(target=Department.class,attr="departmentId",targetAttr="id",type=OrmQuery.Type.ONE),
        @OrmCondition(target=ProductOrder.class,attr="id",targetAttr="userId" ,type=OrmQuery.Type.MANY),
        @OrmCondition(target=Role.class,attr="id",targetAttr="userId" ,sqlId="user.selectRole",type=OrmQuery.Type.MANY)

}
)
 

java代码

 
                List<User> list = sql.select("user.queryUsers", User.class, null);
                User user = list.get(0);
                Department dept = (Department)user.get("department");
                System.out.println(dept.getName());
                List<Role> roles  = (List<Role>)user.get("role");
                System.out.println(roles.size());
