忙乱，热闹。处处手忙脚乱，时时心神不宁。一切时间似乎都不够再用，注意力也永远无法聚焦于一点……凡此种种，有一个特别的名字，叫做浮躁。
浮躁从何而来？起因缘于繁忙。工作繁忙，一人同时辟有多条战线，一年需要完成多项任务，一天被日程充斥，一时可能有几件事情需要处理。于是则浮躁，则心不着地，俨然一只上满发条的时钟，滴答滴答飞转！其实不仅只有繁忙，浮躁与计划也密切相关。事情一多，脑子发懵，心里起火，手足无措。显然，此情此景，计划二字则被淹没。当然，造成浮躁还有一因，或许还十分重要，那就是心理素质。没有经历，没有经验，心理脆弱，毫无主见。此时此刻，众多事情压来，既而丢失计划，浮躁所有生成条件顿时全部具备，有如电脑病毒一样瞬间爆发。
有条不紊，按部就班。时时安然，处处井然。单元时间，所有其它均已排除在外，时时刻刻都在轻松有序的劳作……如此这般，也有一个双音的名字——静心！
为何需要静心？目的在于抵挡浮躁。浮躁一来，忙乱姑且不说，工作效果自然没有成色。工作好坏，并非只是表面上完成与否。工作质量，需要以工作过程的质量作为依托。手忙脚乱的工作，做过工作，心里无所收获。心猿意马的追赶进度，完成的仅是表面文章。静心则不然。静心可以让人呼吸匀称，静心能够叫人心明眼亮，静心帮助人计划分明、胸有成竹，静心还能使人处事坦然。
人人都有忙乱之时，人人都有浮躁之举。而浮躁遗患无穷，当以何物作为护法？若说浮躁是酸，静心则属于碱。为避免浮躁，必以静心相对。高三后半，复习任务繁重，去浮躁，修静心，好处多多。

　　在贵州贵阳赶回上海的飞机上，时值傍晚。夜幕悄悄降临，贵阳的夜来的比沿海城市稍稍迟了一些。云彩朵朵，在飞机的脚下匆匆而过。一边是太阳的余霞，一边是月亮姑娘的脸庞已露出来，夜晚的黑与白天的白相映成趣。

矛盾是普遍存在的。

淅淅沥沥连着下了十几天雨，终于今天晴朗起来了。
春天到了，万物复苏，等待着春姑娘的脚步。

　　这是一个关于鹰的故事。

　　鹰是世界上寿命最长的鸟类，它一生的年龄可达70岁。

　　要活那么长的寿命，它在40岁时必须做出困难却重要的决定。这时，它的喙变得又长又弯，几乎碰到胸脯；它的爪子开始老化，无法有效地捕捉猎物；它的羽毛长得又浓又厚，翅膀变得十分沉重，使得飞翔十分吃力。

　　此时的鹰只有两种选择：要么等死，要么经过一个十分痛苦的更新过程——150天漫长的蜕变。它必须很努力地飞到山顶，在悬崖上筑巢，并停留在那里，不得飞翔。

　　鹰首先用它的喙击打岩石，直到其完全脱落，然后静静地等待新的喙长出来。鹰会用新长出的喙把爪子上老化的趾甲一根一根拔掉，鲜血一滴滴洒落。当新的趾甲长出来后，鹰便用新的趾甲把身上的羽毛一根一根拔掉。

　　5个月以后，新的羽毛长出来了，鹰重新开始飞翔，重新再度过30年的岁月！

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 应用
Any program that sends data through Mule. An application can be a web application, back office system,
application server, or another Mule instance.『应用程序、后台办公系统、应用程序服务器或其它Mule实例』
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 配置构造器
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 连接器
The heart of a transport that maintains the configuration and state for the transport.
endpoint  端点
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过滤器
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 拦截器
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 转换消息格式，针对已注册的服务提供者的需求将消息从一种格式转换到另一种格式。
Routes 路由消息，将消息传输到已注册的服务，并保证传输的服务质量、服务层的特性。
Augments 扩展信息，在传输的内容中添加额外信息，比如关于消息请求者的元数据。在消息中增加新的通信协议内容以满足服务提供者的需求。
Notifies 通知消息监听者的特性消息请求。
Secures 安全传输，对于传输的消息增加消息认证、授权、不可否认性、机密性等机制。

SLD（Style Layer Descriptor）样式层描述符

基于XML语言

创建样式，相对比较简单。
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 文本符号----OK 存在问题：使用中国地图显示异常，请求样式不适用于图层，进一步操作？？？？？？
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. 标签
<Font>: The font and size the label will have. 字体
<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文本的晕环

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,  线
(2)polygon, 多边形
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, 点
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. 光栅
A raster symbolizer consists of a Geometry(几何学), opacity（透明度）, channel selection(路线选择), overlap behavior(交叠事件), color map（颜色地图）, contrast enhancement(对照增强), shaded relief(阴影浮雕) and image outline(图像轮廓).

 

有一些客户本身的需求梳理工作没有进行，但是认识到相应的IT信息建设的必要性。面对这样的技术方案书，就相对难写一些。因为巧妇难为无米之炊。
如何编写这样的技术方案书？
（1）把握管理的通用性。普遍企业上信息系统，主要针对需要进行管理上提升，加强收入和成本的管理，提升客户服务满意度。
（2）把握行业的通用性。针对企业来说，行业的特性也具有普遍性？如何做好企业的运营？行业运营的方案在信息系统中如何体现？
（3）面子工程。作为企业上信息系统，面子形象工程，也是很关键的。提升公司的知名度、品牌效应、提升行业规范性等等。
