springboot+maven快速构建项目的示例代码

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。
