Spring Tool Suite
Version: 3.9.2.RELEASE
File–>New–>Maven Project
在pom.xml文件中进行以下修改:
<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.iamapsycho</groupId> <artifactId>SpringBootTest</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>billingBootTest-iamapsycho</name> <description>Demo project for Spring Boot</description> <!-- spring-boot-starter-parent是Spring Boot的核心启动器, 包含了自动配置、日志和YAML等大量默认的配置,大大简化了我们的开发。 引入之后相关的starter引入就不需要添加version配置, spring boot会自动选择最合适的版本进行添加。 --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> </parent> <dependencies> <!-- spring-boot-starter-web包含了Spring Boot预定义的一些Web开发的常用依赖包 如: spring-webmvc,Tomcat.... --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <properties> <java.version>1.8</java.version> </properties> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
在src/main/java下 创建包com.iamapsycho,并在包内创建Application.java
package com.iamapsycho;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
在src/main/java下 创建包com.iamapsycho.controller,并在包内创建HelloWorldController.java
package com.iamapsycho.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloWorldController {
@ResponseBody
@RequestMapping("/helloworld")
public String helloWorld(){
return "Hello World! This is Spring Boot !!!";
}
}
接下来就运行Application.java,然后访问地址:
http://localhost:8080/helloworld
当需要在spring boot 项目中定义一些变量,设置参数时候,可以在application.yml中进行设置
现在访问 http://localhost:8080/helloworld 将会报错,
应加上项目名称
http://localhost:8080/SpringBootTest/helloworld
