这里有新鲜出炉的精品教程,程序狗速度看过来!

Spring Boot

Spring Boot 项目旨在简化创建产品级的 Spring 应用和服务。你可通过它来选择不同的 Spring 平台。可创建独立的 Java 应用和 Web 应用,同时提供了命令行工具来允许 'spring scripts'.


本篇文章主要介绍了springboot+maven快速构建项目的示例代码,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

最近公司运用springboot构建项目,确实比ssh搭建要快很多。

1.首先要下载maven,用maven管理项目很方便,下载完maven配置好环境,maven我就不细说了。

2.创建一个maven项目,pom.xml文件里面写这些:


<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>springboot</groupId>
  <artifactId>testSpringBoot</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <name>testSpringBoot</name>
  <packaging>jar</packaging>
  <!-- 继承父包 -->
  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.1.3.RELEASE</version>
    <relativePath></relativePath>
  </parent>
  <!-- spring-boot的web启动的jar包 -->
  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
  <!--jpa的jar包 ,操作数据库的,类似hibernate-->
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <!--mysql驱动-->
    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <!--thymeleaf模板jar,是很不错的html数据传递取值,类似jsp的jstl-->
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
  </dependencies>
  <!--maven的插件-->
  <build>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
    </plugins>
  <!-- 配置java版本 不配置的话默认父类配置的是1.6-->
  <pluginManagement>
   <plugins>
    <plugin>
     <artifactId>maven-compiler-plugin</artifactId>
     <configuration>
      <source>1.7</source>
      <target>1.7</target>
     </configuration>
    </plugin>
   </plugins>
  </pluginManagement>
 </build>
</project>

3.创建的文件目录如图:

4.在com.boot(即最外层目录文件)下写一个如下main方法:


package com.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application {
   public static void main(String[] args) {
     SpringApplication.run(Application.class, args);
   }
}

5.在com.boot.web下创建一个类如下:


package com.boot.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class MainController {
//  @RequestMapping("")
//  public String index(){
//    return "examples/index";
//  }
   @RequestMapping("/")
   @ResponseBody
   String home() {
    return "Hello World!";
   }
}

@RequestMapping     @ResponseBody这两个注解都是springMVC的,不懂得可以看springMVC

6.在resources下增加一个application.properties文件

文件内容如下配置:


spring.datasource.platform=mysql
spring.datasource.url=jdbc:mysql://localhost/springboot?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true&autoReconnect=true&failOverReadOnly=false
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driverClassName=com.mysql.jdbc.Driver
# Advanced configuration...
spring.datasource.max-active=50
spring.datasource.max-idle=6
spring.datasource.min-idle=2
spring.datasource.initial-size=6
#create table
spring.jpa.hibernate.ddl-auto=validate

server.port=8080
server.session-timeout=30
server.tomcat.uri-encoding=utf-8

spring.thymeleaf.prefix=classpath:templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=utf-8
spring.thymeleaf.content-type=text/html 
spring.thymeleaf.cache=false

该文件的配置可以参考springboot的官网

该文件的全部参数配置;如下(摘自官网)

7.找到com.boot下的Application以java Application方式启动,然后打开浏览器输入localhost:8080就会出现Hello World!

这样一个简单的web开发就搭建好了。

8.启动图片:
