如何用springboot创建maven的依赖工程

Answer 1

最近公司运用springboot构建项目，确实比ssh搭建要快很多。springboot官方学习网站

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:
<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。
