spring boot学习（一）---建项目结构

最近开始学习spring boot 在这里记录下,学习内容是根据慕课网的廖师兄的课程结合自己编写的。

一 搭建项目结构

1.使用eclipse 创建maven项目

选择 maven-archetype-webapp

在pom.xml中填写所需jar包，注意：需要继承父类的 pring-boot-starter-parent

<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/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.springboot.api</groupId>  <artifactId>springboot</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>springboot Maven Webapp</name>  <url>http://maven.apache.org</url>   <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.4.1.RELEASE</version>        <relativePath></relativePath>    </parent>  <dependencies>     <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>         <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</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>  <build>  <plugins>        <plugin>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-maven-plugin</artifactId>        </plugin>    </plugins>    <finalName>springboot</finalName>  </build></project>

2.创建对应项目结构

（我的是这个样子）

3.编写配置文件application.properties

spring.datasource.platform=mysqlspring.datasource.url=jdbc:mysql://127.0.0.1:3306/springboot?useUnicode=yes&characterEncoding=UTF-8spring.datasource.username=spring.datasource.password=spring.datasource.driverClassName=com.mysql.jdbc.Driver# Advanced configuration...spring.datasource.max-active=50spring.datasource.max-idle=6spring.datasource.min-idle=2spring.datasource.initial-size=6#create tablespring.jpa.hibernate.ddl-auto=validateserver.port=8080#server.context-path=/bootserver.session-timeout=30server.tomcat.uri-encoding=UTF-8

（username和password自行填写）

spring boot 同时也支持yaml配置
格式如下

server:  port: 8080

4.编写启动类 Application.java

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

编写测试用的Controller HelloController.java

5.编写测试用的Controller HelloController.java

“`
package com.boot.web;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {

@ResponseBody@RequestMapping(value="/hello" ,method = RequestMethod.GET)

public String say(){
return “spring boot!”;
}
}

回到Application.java 文件下 启动main函数
第一个springboot应用就启动了

在浏览器中输入 http://localhost:8080/hello
可以看到spring boot!

第一个spring boot应用就搭建完成
