Build an environment

1. IDE uses the J2EE version of Eclipse. To ensure that Maven is installed, you can use Eclipse's Install New Software to install it.

Then click Next, install it and restart it again.

Note: when using the latest version of Eclipse, you can skip this step because the latest version of Eclipse already has built-in Maven.

2. After installing Maven, do not use the Maven that comes with IDE. Download one officially, and then let the Maven of IDE point to the Maven path of your download and installation, as shown in the figure:

Create a Maven project

1. Create a new Maven Project,File- > New- > Other- > Maven Project, select default, then click Next, and select maven-archetype-webapp in Select an Archetype, as shown below:

2. Click Next, type groupId:xxx;artifactId:xxx, then click Finish, wait a while, and then create it. The following figure shows an initial project that has been created:

IV. Customize the Maven project structure

Now the created project structure is not a standard Maven project structure, so you need to adjust the project structure.

1. Add Source Folder

Add three Source Folder of src/main/java,src/test/java and src/test/resources, right-click the project root directory and click New-> Source Folder to create the three Source Folder. Note that instead of building an ordinary Folder, it is Source Folder, as shown in the figure:

Note: you can also add src/test/java and src/test/resources for Junit testing here.

2. Create a package

Create 3 packages in src/main/java (the maven standard recommends a 3-tier package structure).

3. Modify JRE

Modify the JRE System Libary according to JDK.

4. Create a Web-related folder

You can think of src/main/webapp as WebRoot, and create folders such as js,css,jsp in this directory.

At this point, the directory structure of the project is shown in the figure:

Configure the project BuldPath1 and change the classes path

Right-click the project-> Properties- > Java Build Path-> Source, and there should be these four folders below: src/main/java,src/main/resources,src/test/java, src/test/resources. Double-click the Output folder for each folder and select the path:

① src/main/java,src/main/resources, select target/classes

② src/test/java, src/test/resources, select target/test-classes

Choose Allow output folders for source folders.

2. Change the display order of folders

Click Order and Export to change the order in which folders are displayed.

3. Change the JDK version

Double-click JRE System Library in Libraries, and version 1.6 or 1.7 is recommended.

Turn the project into a Dynamic Web project

Note: if you create a Maven Project with the latest version of Eclipse, the project is already a Dynamic Web project by default, and only the Dynamic Web version needs to be adjusted here.

1. Conversion project

Right-click Project-> Properties- > Project Facets, and click Convert to faceted from, as shown in the figure:

2. Configure Project Facets

Change the Version of Dynamic Web Module to 2.5. (3.0for Java7). If the prompt is wrong, you may need to set the Compiler compliance level to 1. 6 in Java Compiler. Or you need to change the Version of the Java in this window to 1.6.

3. Configure Modify Faceted Project

Click Further configuration available... , pop-up Modify Faceted Project window, here is to set the path of the web.xml file, enter src/main/webapp,Generate web.xml deployment descriptor to generate the web.xml file automatically, optional or not.

Setting up deployment assemblies (Web Deployment Assembly)

Right-click Project-> Properties- > Deployment Assembly, as shown in the figure:

The list here is the path to the file release when the project is deployed, and you need to do the following:

① We removed two items from test because test is for test use and does not need to be deployed.

② sets the jar package of Maven to be published under lib, Add-> Java Build Path Entries-> Maven Dependencies-> Finish

The completion effect of the configuration is as shown in the figure:

8. Configuration file 1. Configure pom.xml

Add the necessary jar package dependence to the pom file, which can be queried from two places:

After modifying the pom file, save, maven will automatically go to download these jar packages to the local.

2. Configure web.xml

Configure Spring,spring MVC,log4j, garbled handling, etc.

3. Configure properties

Add configuration files such as log4j.properties,jdbc.properties

4. Configure ApplicationContext.xml

The ApplicationContext.xml file is the configuration file for Spring

5. Configure xxx-servlet.xml

The xxx-servlet.xml file is the configuration file for SpringMVC, and the name of the xxx is configured in the web.xml file.

6. Configure ImplAndBusinessBeans.xml

ImplAndBusinessBeans.xml files mainly place bean objects for implementation and Business.

7. Configure SqlMapConfig.xml

The SqlMapConfig.xml file is the configuration file for Mybatis

8. Configure Test.xml

The Test.xml file is the Mapper configuration file for Mybatis

9. Create a package

Bean: put pojo, java bean

Business: put the business layer

Conroller: put the control layer, which is mainly responsible for accepting requests and calling business, and returns the view result.

Dao: put the interface corresponding to each bean

Impl: the concrete implementation of dal interface

Interceptor: filter

Resource: resource bundle, such as file path, configuration file

Test: test package

Util: toolkit

The full package name configuration path is shown in the figure:

Write the project code

Considering the length, all the code is omitted here. For more information, please see the Google Code link provided in the first part of the article.

11. The overall structure of the project

1. Use Alibaba Druid connection pool (efficient, powerful and scalable database connection pool, monitor database access performance, support Common-Logging, Log4j and JdkLog, monitor database access)

two。 Provide high concurrency JMS message processing mechanism

3. All functional modularization, all module service, all service atomization, provide an extensible service model, so that the program runs stably and never downtime.

4. Provides Wink Rest and Webservice services, so it can be deployed as an independent service platform

Framework integration:

Springmvc + Mybatis + Shiro (permission) + REST (Service) + WebService (Service) + JMS (message) + Lucene (search engine) + Quartz (scheduled scheduling) + Bootstrap Html5 (support for PC, IOS, Android)

Introduction to the framework:
