1. Create a Java Project

1) file ---> New ---> other ---> Maven projet

2) Select Maven-Archetype-Quickstart.

2. Create a WEB Project

1) file ---> New ---> other ---> Maven projet

2) Select Maven-Archetype-webapp

 

3) Fill in the project information

 

4) production Web project package structure

 

 

 

4.1) convert the project to dynamic web module, right-click the project, select Properties, select project facets, and click convert to faceted form...

Select dynamic web module and select 3.0 to support servlet3.0.

Select Java and JDK 1.6 or later.

4.2) the tool generates only one source folder named src/main/resource, we need to manually add src/main/Java, src/test/Java and src/test/resource three source folder, right-click the Project New ----> source folder, enter the folder name.

 

4.3) modify the source folder compilation path, enter the Java build bath window, double-click the Output Folder under each folder, and specify the path.

Src/main/Java and src/main/resource Specify target/calsses, src/test/Java and src/test/resource Specify target/test-classes

Select allow output folders for source folders.

4.4) configure and deployProgramDeployment Assembly: Delete the two items of test. This is not required when the test program is released. Add the maven dependency library and release it to the lib directory during release, add/src/main/webapp as the root directory for deployment

5) Configure Tomcat 7 and release the running project
