Engineering Building

The tools used in this project are:

JDK1.8
Maven
Idea

Open idea, create a new project, then right-click the project, create a new module, select Spring INITIALIZR

Then next, fill in group, artifact, and Next,

Select Web,next to complete the project creation.
The project catalog is as follows:

-src
    -main
        -java
            -package
                -springbootapplication
        -resouces
            -statics
            -Templates
            -application.yml
    -test
-Pom

The pom file is as follows:

<?xml version= "1.0" encoding= "UTF-8"?> <project xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "http ://www.w3.org/2001/XMLSchema-instance "xsi:schemalocation=" http://maven.apache.org/POM/4.0.0/http Maven.apache.org/xsd/maven-4.0.0.xsd "> <modelVersion>4.0.0</modelVersion> <groupid>com.spri Ngcloud</groupid> <artifactId>springboot</artifactId> <version>0.0.1-snapshot</ version> <packaging>jar</packaging> <name>springboot</name> <description>dem o Project for Spring boot</description> <parent> <groupid>org.springframework.boot</grou Pid> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.release</v Ersion> <relativePath/> <!--lookup parent from repository to </parent> <propert Ies> &LT;PROJECT.BUILD.SOURCEENCODING&GT;UTF-8&LT;/project.build.sourceencoding> <project.reporting.outputencoding>utf-8</ project.reporting.outputencoding> <java.version>1.8</java.version> </properties> &lt

Modify the program entry class as follows:

/**
 * @author wang_ * *
@SpringBootApplication public
class Springbootapplication extends Springbootservletinitializer {

    @Override
    protected Springapplicationbuilder Configure ( Springapplicationbuilder application) {
        return application.sources (Springbootapplication.class);
    }

    public static void Main (string[] args) {
        springapplication.run (springbootapplication.class, args);
    }
}

Modify the configuration file as follows:

# Server settings (serverproperties)
#端口
server.port=8082
server.address=127.0.0.1
# server.sessiontimeout=30
#访问路径名称
server.contextpath=/boot

Create a new Test.controller package and create a new Web class:

/**
 * @Package: Com.springboot.test.controller
 * @ClassName:
 Test * @Description: Testing Web
 * @Author Shuyu.wang
 * @Date 2017-12-07 10:05
 **/
@RestController public
class TestController {
    @ Requestmapping (value = "/hello", method = requestmethod.get) public
    String Hello () {
        return  ' Hello Spring Boot ";
    }
}

Run the program and see the console:

The description program started successfully.

Then the browser accesses: Http://127.0.0.1:8082/boot/hello
Return:

Hello Spring Boot
First spring Boot project completed
