1, spring-boot Study notes (a) Simple introduction

First, the new general Maven project

Pom.xml

<parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>1.5.4.RELEASE</version>    <relativePath/>  </parent>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <java.version>1.8</java.version>  </properties>    <dependencies>  <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-web</artifactId>    </dependency>  </dependencies>  <build>  <plugins>      <plugin>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-maven-plugin</artifactId>      </plugin>    </plugins>    <finalName>SpringBoot001_HelloWorld</finalName>  </build>

Second, write the code

@SpringBootApplication@RestControllerpublic class Application{ @RequestMapping("/hello") public String hello(){  return "hello world"; } @RequestMapping("/geeting") public String geeting(){  return "Index page"; }  @RequestMapping("/geeting/{user}") public String get(@PathVariable("user") String name ){  if(name.equals("zhangsan")){   return name+" Hello";  }  return "hello"; } public static void main(String[] args) {  SpringApplication.run(Application.class, args); }}

* * @SpringBootApplication * *: Specifies whether the Springboot app

* * @RestContrller * *: This is generally added to the class, indicating that this is a rest application, each method returned is no longer a view

* * @RequestMapping * *: URL path mapping

* * @PathVariable * *: The value of the variable in the read path is assigned to name

Third, code execution

Execute the Java-jar jar package path on the command line by MVN the package directly first

The following content as an understanding; wait till the century is applied.

Iv. Cessation of

1), forced stop

ps aux | grep spring | xargs kill -9

2), stop through the front desk

3), add password Authentication
