<bean class="Person>
	<propety name="lastname" vlaue="字面量/${key}从环境变量，配置文件中获取值/#{SpEl}"></Propety>
</bean>

上面的这些代码，就相当于@Value的作用，@Value的写法和上面代码的Value一样

@Value直接放在你要赋值的对象上

@Value("${person.lastname}");  //这是从配置文件中读取信息的写法

private String lastname;
@ConfigurationProperties和@Value的功能比较



//这个类的所有方法返回的数据直接返回给浏览器

//@ResponseBody

//@Controller

@RestController

public class HelloController {

fnd_profile.value的用法：
select fnd_profile.value('gl_set_of_books_id')

   from dual

select fnd_profile.value('mfg_organization_id')

   from dual   --取子库

select fnd_profile.value('GL_SET_OF_BKS_ID')

   from dual--取帐套 


用此方式調整正確的當前咝协h境,特別是在multi_org環境下(在報表前,報表後均要執行因有可能在咝羞^程中變量被人為改變)
有一些view用到org環境參數的,一般要如下設定後,才能select到記錄:
begin
dbms_application_info.set_client_info(:org_id);--如1,2,3之類的
end;


可用'FND_PROFILE.GET' function 查看以下一些參數
取得set of book id
Select fnd_profile.value('GL_SET_OF_BKS_ID') from dual
取得master_id
select fnd_profile.value('SO_ORGANIZATION_ID') from dual;
取得當前org_id
select to_number(fnd_profile.value('ORG_ID')) from dual;
org_id = :$PROFILES$.ORG_ID;也可用此來取得,在定義報表參數時來定義


fnd_profile.value('MFG_ORGANIZATION_ID') 與上的區別
取得當前user_id
select TO_NUMBER(FND_PROFILE.VALUE('USER_ID')) from dual;
FND_GLOBAL.USER_ID 用此方式在report中有可能不好用,在report中建議用上一種方式FND_WHO.PROFILE('USERID') 又一種方式取得當前login_id
select TO_NUMBER(FND_PROFILE.VALUE('login_ID')) from dual;
取得當前username
Declare

username varchar2(30);

begin

username := FND_PROFILE.VALUE('USERNAME');

end;
另獲取username 也可以用FND_Global.User_Name
fnd_global package可以取得一些關於當前login in用戶的信息
取得當前request_id
select FND_PROFILE.VALUE('CONCURRENT_REQUEST_ID') from dual;
FND_REQUEST.SUBMIT_REQUEST 另一種方式
請看fnd_concurrent_requests functions
在PL/SQL Develop中没有环境变量，所以如果要查询多组织的View，需要先执行设置环境变量函数
dbms_application_info.set_client_info(81);end;与

 BEGIN    fnd_client_info.set_org_context(82)END; 效果一样,这个81是指OU_ID，业务实体的ID .al--取帐套

tf.clip_by_value的用法



tf.clip_by_value(A, min, max)：输入一个张量A，把A中的每一个元素的值都压缩在min和max之间。小于min的让它等于min，大于max的元素的值等于max。

例如：





[python] view
 plain copy





import tensorflow as tf;  

import numpy as np;  

  

A = np.array([[1,1,2,4], [3,4,8,5]])  

  

with tf.Session() as sess:  

    print sess.run(tf.clip_by_value(A, 2, 5))  


输出：



[[2 2 2 4]

 [3 4 5 5]]

从用法和底层梳理，比较详细。原链接地址

总结下编程思想：

无论何种介质的配置，加载到本地后封装好，在初始化bean时碰到@Value注解，就去去封装好的类中去解析得到key对应的value，赋值到类的属性。动态刷新时，碰到需要动态刷新的类，直接重新实例化该类就可以了（重新走下@Value解析流程）
