In-depth introduction to the Mybatis series (6) --- objectFactory, plugins, mappers introduction and configuration, mybatismappers
The previous article titled Mybatis series (v) --- TypeHandler introduction and configuration (mybatis source code) briefly gave a look at TypeHandler. This will end the study of mybatis configuration files, configuration of several nodes not mentioned in this section: objectFactory, databaseIdProvider, plugins, and

Once defined, the configuration is as follows: 3, mappers, this leads to mybatis one of the core, mappers role? Do I need to configure it?Under the Mappers node, configuring our Mapper mapping file, the so-called mapper mapping file, is a bridge for MyBatis to buil
fact, Parameterhandler is selected. Resultsethandler is the process of returning results.How to customize plugin? How to configure?To customize a plugin, you need to implement the Interceptor interface, here is not detailed, the latter part of the actual combat will be explained in detail. Once defined, the configuration is as follows:Configuration> ...... Plugins> pluginInterceptor= "Org.mybatis.example.ExamplePlugin"> Propertyname= "Someproperty"value= "+"/> plugin>
Here I simply tell you how to parse the XML configuration file and finish loading when creating the Sqlsessionfactory object.
The mapperelement is called to parse the mappers when the configuration node and child nodes are parsed from the MyBatis profile.
/**

That This mapper can also be seen by name, and is based on the Bean's name as a URL, so when configuring the handler bean, configure the Name property, set to the URL to be requested to correctly map.There is also a processor mapper called a simple mapper: org.springframework.web.servlet.handler.SimpleUrlHandlerMapping. The mapping method is directly based on the URL, as follows: This can be directly with

Mapper interface, Mpper XML file and mappers configuration
The Mapper XML file is used to map the defined Mapper interface to the corresponding SQL statement, which simplifies the process of dealing with the database, and can be configured to directly load the result of the query into the object you want to return to you.
This article only from the definition of the Mapper interface to Mybatis-config.xml in the Mapper registration, no detailed explan
Last month, acnchen, Business Development Manager of Bing (Bing Maps) Greater China, published an article titled loading other Maps (Google satellite Maps, etc.) in the Bing map SilverLight control, it details how to load Google satellite maps. This article is similar to this article. In addition to Google satellite
As described in the first article of this series, developing Bing Maps based on Silverlight requires a development Key in addition to the development environment. What is this Key used? The Silverlight control is an essential parameter for map rendering. It can be understood as Microsoft Bing Maps, which is an authorization Development Key activated by users, this article attempts to use a simple example dr
A few days ago, the project used network maps, mainly Baidu maps and search maps, or sogou maps and Google Maps. The search scope is mainly in Beijing urban areas, and a bit is used in the suburbs. The advantages and disadvantages are summarized as follows:

surface details of the polygon facing the screen are enhanced, rather than the whole model. Therefore, the performance cost is not as high as that of direct upper mode. In comparison, the displacement Paster has no flaws in the effect, but it does not have any disadvantages. First, hardware requirements are high. shadermode3.0 must be supported, because Sm3 can be used for texture operations at the vertex stage. At the same time, mosaic consumes a lot of performance. However, in terms of GPU pr
future dx10 uniform rendering architecture.
Compared with all the concave and convex pasters we have introduced, displacement pasters are the only way to change the geometric shape of a polygon surface. Compared with the light tracing algorithm to be introduced later, the performance consumption of this algorithm is not dominant, but it is actually more reasonable. It gives the screen more special effects. What's more interesting is that it does not conflict with other pixel-based concave and c
The OSM (OpenStreetMap-Open Street Map) service is an implementation type that allows you to publish your own map data images, the motive behind the establishment of open street maps is to create and provide geographical information (like street maps) that can be freely used to everyone who wants to use them, just as free software gives users freedom, this article describes how to use the map service releas
The function navigation provided by Bing Maps Silverlight Control is very powerful. In terms of design, it provides great support for extensions and provides commands and buttons that can be extended and directly used by many users, if you are not clear, you can view the article "Custom navigation bar" that I wrote earlier. However, compared with the functional navigation menu provided in DeepEarth, the menu is not so bold and dynamic. I personally pr
As you know, Google Maps is more and more popular around the world. Is it possible to integrate Google Maps into my MapGuide Enterprise Fusion viewer as base map? Yes, it is!
As MapGuide Fusion viewer uses a subset of OpenLayers, it allows us to access to the underlying OpenLayers API. in this article, we will show you how to integrate Google Maps into our exist
I believe that most of the users who use Bing Maps for development have seen the following picture: when we develop Bing Maps, a prompt error occurs when the Development KEY is incorrect, resulting in user authorization verification failure.
The disadvantage of using Bing Maps Silverlight Control is that it uses the online map data provided by Microsoft
The Bing maps provides a set of WCF map services that we can use to facilitate geographic search and other related functions in our application systems. They are geocoding services (geocodeservice), geo-imaging Services (IMAGERYSERVICE), Routing function Services (Routeservice), and geographical search services (Searthservice).
I. Geographic coding services (Geocodeservice)
The Map Coding service provides the function of matching the map address (bo
How can I use Google map data in the Google Maps API?
This is almost the most common question I have heard about Google Maps APIs. As we all know, Google Maps does not have a detailed map of China. In China, we only have a unique Google map website that provides a detailed map of China. The reason for this situation has not been officially explained by Google a
