This article first describes how to configure the Maven+scala development environment in Eclipse, and then describes how to implement the spark local run. Finally, the spark program written by Scala is successfully run.
At first, my Eclipse+maven environment was well configured.

Add struts and hibernate support (Eclipse) for Web engineering
One: Add struts support:
1: Build your own Web project.
2: Add struts support to the Web app, and first copy the jar files from the Lib directory under struts to the Web-inf/lib directory of the Web App.
3: If you need to use the tag library of struts, you should copy all the TLD
Development is used by Eclipse, which has engineering files. Project this file, run Release:prepare when the report exception:Cannot prepare the release because you have local modificationsYou are prompted to have the file not submitted, the normal file can be submitted, but this file we have to let the plugin itself filter out.The configuration is as follows: O
First, preface:This section describes some of the basics of Cocos2d-x 3.0, and compiles our cocos2d-x project on Eclipse to successfully execute HelloWorld. After reading this blog post. You'll know that Cocos2d-x 3.0 has changed so much. has become so simple, the environment construction, the project creation, compiles the way to be more humanized. Second, the Environment preparation:1. Download the ADT Bundle (E

When using MAVEN development, because the project is usually divided into several modules (the main module depends on other modules), the debugging process need to see the other module code is a long-seeing requirement.This article describes how to set up to meet this requirement when you debug:(i) Runtime selection dependent workspace Resolve Workspace artifacts(ii) Refresh options Check Refresh resources upon completion(iii) Source tab added to workspace workspaceIf you need to see the source
ensure that the mapping relationship is unified, there will be hidden trouble.3. Development, maintenance is unfavorable. Because if either side needs to be replaced for some reason, it is often necessary to change both sides so that the likelihood of inconsistent mapping is not only greater, but inefficient. And if the use of reverse engineering, it is easy to solve.So, because of the project, I studied t

1. Gradle Installation:Download the latest version from the official website www.gradle.org and add the Gradle_home/bin directory to the System environment variable path after decompression. Test whether the configuration was successfully run at the command line: GRADLE-V will print out information such as the Gradle version number.2. Gradle Basic use:After creating a new project, create a Build.gradle file under the project

reason, it is often necessary to change the two sides. In this case, the possibility of inconsistent mappings is not only greater, but also inefficient. However, if positive and reverse engineering is used, it is easy to solve the problem.
Therefore, for project reasons, I studied how to reverse generate the hibernate entity class from the database.

Controlling the Eclipse Rich customer Platform (RCP) is a powerful software platform that allows developers to build common applications based on interconnection and collaboration between Plug-ins. RCP allows developers to focus on the development of application business code without taking the time to reinvent the wheel to write application management logic.

The development of the general DAO layer is this, the first database design, what e-R diagram, and so on, and then select a database products, to build a good table. Finally, the Java entity and mapping file are generated in reverse, which guarantees consistency and convenience.
If you use MyEclipse, reverse is easier, use eclipse must use Plug-ins, but myeclipse
