spring-boot从创建到部署(内含swagger配置)

今天介绍一下spring-boot这个开箱即用的框架，从创建到部署

创建spring-boot项目

• 首先点击creat new project
  
• 然后点击spring initializr
  
• 输入组名和项目名
  
• 选择web
  
• finsh完成创建
  
• pom.xml配置文件

<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">

    build>

project>

• 此时会发现在target目录下有了loginDemo-0.0.1-SNAPSHOT.jar文件
  
• 将这个文件上传到服务器上，服务器上要确保已经成功安装jdk。
• 使用nohup java -jar loginDemo-0.0.1-SNAPSHOT.jar即可运行项目(加nohup代表一直执行，不会停止，否则关闭就会停止项目)
• 使用tail -f nohup.out即可查看动态日志
• 或者使用java -jar loginDemo-0.0.1-SNAPSHOT.jar > log.file 2>&1 &(有时候断开与服务器连接，项目还是会停止)

如果需要在项目上部署swagger，请看下面的教程

添加swagger2

• 首先在pom.xml中添加两个依赖

        <dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger2artifactId>
            <version>2.7.0version>
        dependency>
                <dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger-uiartifactId>
            <version>2.7.0version>
        dependency>

• 然后添加一个Sagger2配置类

package com.stalary;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.context.request.async.DeferredResult;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2 {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("demo")
                .genericModelSubstitutes(DeferredResult.class)
                .useDefaultResponseMessages(false)
                .apiInfo(apiInfo())
                .pathMapping("/")
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.stalary.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("登陆测试模块")
                .description("源码请访问：https://github.com/stalary/SpringBootDemo")
                .termsOfServiceUrl("stalary.com")
                .version("1.0")
                .build();
    }
}

这时访问http://120.24.5.178:8100/swagger-ui.html#/即可展示出页面
