忙亂，熱鬧。處處手忙腳亂，時時心神不寧。一切時間似乎都不夠再用，注意力也永遠無法聚焦于一點……凡此種種，有一個特別的名字，叫做浮躁。
浮躁從何而來？起因緣于繁忙。工作繁忙，一人同時辟有多條戰線，一年需要完成多項任務，一天被日程充斥，一時可能有幾件事情需要處理。于是則浮躁，則心不著地，儼然一只上滿發條的時鐘，滴答滴答飛轉！其實不僅只有繁忙，浮躁與計劃也密切相關。事情一多，腦子發懵，心里起火，手足無措。顯然，此情此景，計劃二字則被淹沒。當然，造成浮躁還有一因，或許還十分重要，那就是心理素質。沒有經歷，沒有經驗，心理脆弱，毫無主見。此時此刻，眾多事情壓來，既而丟失計劃，浮躁所有生成條件頓時全部具備，有如電腦病毒一樣瞬間爆發。
有條不紊，按部就班。時時安然，處處井然。單元時間，所有其它均已排除在外，時時刻刻都在輕松有序的勞作……如此這般，也有一個雙音的名字——靜心！
為何需要靜心？目的在于抵擋浮躁。浮躁一來，忙亂姑且不說，工作效果自然沒有成色。工作好壞，并非只是表面上完成與否。工作質量，需要以工作過程的質量作為依托。手忙腳亂的工作，做過工作，心里無所收獲。心猿意馬的追趕進度，完成的僅是表面文章。靜心則不然。靜心可以讓人呼吸勻稱，靜心能夠叫人心明眼亮，靜心幫助人計劃分明、胸有成竹，靜心還能使人處事坦然。
人人都有忙亂之時，人人都有浮躁之舉。而浮躁遺患無窮，當以何物作為護法？若說浮躁是酸，靜心則屬于堿。為避免浮躁，必以靜心相對。高三后半，復習任務繁重，去浮躁，修靜心，好處多多。

　　在貴州貴陽趕回上海的飛機上，時值傍晚。夜幕悄悄降臨，貴陽的夜來的比沿海城市稍稍遲了一些。云彩朵朵，在飛機的腳下匆匆而過。一邊是太陽的余霞，一邊是月亮姑娘的臉龐已露出來，夜晚的黑與白天的白相映成趣。

矛盾是普遍存在的。
////////////////////////////////////////////////////////////////////////////////////////////
淅淅瀝瀝連著下了十幾天雨，終于今天晴朗起來了。
春天到了，萬物復蘇，等待著春姑娘的腳步。

　　這是一個關于鷹的故事。

　　鷹是世界上壽命最長的鳥類，它一生的年齡可達70歲。

　　要活那么長的壽命，它在40歲時必須做出困難卻重要的決定。這時，它的喙變得又長又彎，幾乎碰到胸脯；它的爪子開始老化，無法有效地捕捉獵物；它的羽毛長得又濃又厚，翅膀變得十分沉重，使得飛翔十分吃力。

　　此時的鷹只有兩種選擇：要么等死，要么經過一個十分痛苦的更新過程——150天漫長的蛻變。它必須很努力地飛到山頂，在懸崖上筑巢，并停留在那里，不得飛翔。

　　鷹首先用它的喙擊打巖石，直到其完全脫落，然后靜靜地等待新的喙長出來。鷹會用新長出的喙把爪子上老化的趾甲一根一根拔掉，鮮血一滴滴灑落。當新的趾甲長出來后，鷹便用新的趾甲把身上的羽毛一根一根拔掉。

　　5個月以后，新的羽毛長出來了，鷹重新開始飛翔，重新再度過30年的歲月！

We also introduced some core JBI concepts:

• JBI container 
• JBI components  
  • Service Engines (SE) provide additional ways of building business services  
  • Binding Components (BC) add the necessary transports to have our ESB communicate with the rest of the world
• Service assemblies (SA), which contain service units (SU) 
• Internal and external endpoints
  container
  components: SE BC

SA SU
endpoints

agent 代理
A service such as the Mule JMX agent that is used by or associated with Mule but is not a Mule-managed
service component. An agent is registered with the Mule Manager and has the same lifecycle as the Mule
instance, so you can initialize and destroy resources when the Mule instance starts or stops.
application 應用
Any program that sends data through Mule. An application can be a web application, back office system,
application server, or another Mule instance.『應用程序、后臺辦公系統、應用程序服務器或其它Mule實例』
channel 通道
A logical pathway on which messages are sent
on a messaging framework. Channels connect
services together as well as different Mule nodes
across a local network or the Internet.
configuration builder 配置構造器
A class that knows how to parse a given configuration file. The default configuration builder is the
org.mule.config.MuleXmlConfigurationBuilder class that knows how to parse a Mule XML configuration file.
connector 連接器
The heart of a transport that maintains the configuration and state for the transport.
endpoint  端點
A configuration entity specifying how and where
a message should be routed. The endpoint is
configured in an inbound or outbound router
and specifies where the message should be
sent or from where it should be received, using
which transport (and optionally which connector
in that transport), and which filters should be
applied before routing the message.
Enterprise Service Bus (ESB)
An architecture that allows different applications to communicate with each other by acting as a
transit system for carrying data between applications within or outside your intranet. An ESB provides
transaction management, routing, security, and other functionality for the messages.
filter過濾器
Specifies logic for determining which messages
are routed to a component. You can set filters
on an inbound router to filter which messages
that service component can receive, or you can
set filters on an outbound router to indicate how
you want to route messages after they have been
processed by the service component.
inbound router 入站路由
A Java class that you configure in the Mule configuration file to determine how a service component will
receive messages. The inbound router includes an endpoint that indicates where the messages will come
from.
interceptor 攔截器
A Java class that is used to intercept message flow into a service component. An interceptor can be used
to trigger or monitor events or interrupt the flow of the message.

Transforms 轉換消息格式，針對已注冊的服務提供者的需求將消息從一種格式轉換到另一種格式。
Routes 路由消息，將消息傳輸到已注冊的服務，并保證傳輸的服務質量、服務層的特性。
Augments 擴展信息，在傳輸的內容中添加額外信息，比如關于消息請求者的元數據。在消息中增加新的通信協議內容以滿足服務提供者的需求。
Notifies 通知消息監聽者的特性消息請求。
Secures 安全傳輸，對于傳輸的消息增加消息認證、授權、不可否認性、機密性等機制。

SLD（Style Layer Descriptor）樣式層描述符

基于XML語言

創建樣式，相對比較簡單。
1. SLD Hello World
1.1 Create the SLD File----OK
1.2 Load Your New SLD  ----OK
1.3 Give a FeatureType Your New SLD---OK
View the Style---OK

2. SLD Text Symbolizers 文本符號----OK 存在問題：使用中國地圖顯示異常，請求樣式不適用于圖層，進一步操作？？？？？？
Modify the SLD File to Include Text Symbolizers
<Label>: What label to give each rendered object. Here we use an attribute of the object, "TYPE". The property name is case sensitive. 標簽
<Font>: The font and size the label will have. 字體
<Fill>: The color that we will fill the font with 填充
3. Outlines and Filters -----OK
<ogc:Filter>
 <ogc:Not>
  <ogc:PropertyIsEqualTo>
   <ogc:PropertyName>TYPE</ogc:PropertyName>
   <ogc:Literal>highway</ogc:Literal>
  </ogc:PropertyIsEqualTo>
 </ogc:Not>
</ogc:Filter>

<ogc:PropertyIsLessThan>
<ogc:PropertyIsGreaterThan>

The halo is essentially a buffer outline of the text.  halo文本的暈環

4. What SLDs are, a text approach
SLD (Styled Layer Descriptor) is a specification put out by the OGC, that defines an XML language to allow users to define symbolization of their feature data. It was written to be a complement to their Web Map Service (WMS) specification, by extending it to allow users a way to define how they want to visualize their features.

Then there are 5 types of symbolizers you can use to actually portray the features,
(1)line,  線
(2)polygon, 多邊形
A Polygon Symbolizer has a geometry and a stroke, just like a line symbolizer, but also has a 'fill', defining what color to put in the center. Can be straight color, or a graphic, of varying opacity and the like.
(3)point, 點
A point symbolizer is made up of a geometry and a Graphic. A graphic is made of either an External Graphic, or a Mark, and has an opacity, a size, and a rotation. Opacity is the same as for the other symbolizers, Size is the absolute size of the graphic in pixels (default is to be dynamic), and rotation defines the rotation of the graphic in the clockwise dimension in decimal degrees. A Mark has a well known name (like square, circle, star, ect.), and a fill and a stroke. An External Graphic uses an xlink to refer to the location of an resource on the web to use to represent the point.
(4)text, 文本
A text symbolizer is made up of a Geometry, a Label, a Font, a LabelPlacement, a Halo, and a Fill.
(5)and raster. 光柵
A raster symbolizer consists of a Geometry(幾何學), opacity（透明度）, channel selection(路線選擇), overlap behavior(交疊事件), color map（顏色地圖）, contrast enhancement(對照增強), shaded relief(陰影浮雕) and image outline(圖像輪廓).

 

有一些客戶本身的需求梳理工作沒有進行，但是認識到相應的IT信息建設的必要性。面對這樣的技術方案書，就相對難寫一些。因為巧婦難為無米之炊。
如何編寫這樣的技術方案書？
（1）把握管理的通用性。普遍企業上信息系統，主要針對需要進行管理上提升，加強收入和成本的管理，提升客戶服務滿意度。
（2）把握行業的通用性。針對企業來說，行業的特性也具有普遍性？如何做好企業的運營？行業運營的方案在信息系統中如何體現？
（3）面子工程。作為企業上信息系統，面子形象工程，也是很關鍵的。提升公司的知名度、品牌效應、提升行業規范性等等。
