跟随SpringBoot的文档(http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-documentation)学习,前后几章关联才调通代码,煞是痛苦,在这里记录结果,过程隐忍。
一、准备工作
1、根据Maven工程特点,建立文档结果
myFirstProject
+-src
+-main
+-java
+-resources
+-test
+-java
+-resources
2、再在src/main/java下依次建立文件夹com,example,myFirstProject,可以构成Maven工程包(package)–>com.example.myFirstProject,最后文档结构如图1
图1
3、编制pom.xml,存于myFirstProject文件夹下,与src同级
<?xml version="1.0" encoding="UTF-8"?>
<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>com.example</groupId>
<artifactId>myFirstproject</artifactId>
<version>0.0.1-SNAPSHOT</version>
<!-- Inherit defaults from Spring Boot -->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.0.BUILD-SNAPSHOT</version>
</parent>
<!-- Add typical dependencies for a web application -->
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
<!-- Package as an executable jar -->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
<!-- Add Spring repositories -->
<!-- (you don't need this if you are using a .RELEASE version) -->
<repositories>
<repository>
<id>spring-snapshots</id>
<url>http://repo.spring.io/snapshot</url>
<snapshots><enabled>true</enabled></snapshots>
</repository>
<repository>
<id>spring-milestones</id>
<url>http://repo.spring.io/milestone</url>

<pluginRepositories>

</pluginRepository>
<pluginRepository>
<id>spring-milestones</id>
<url>http://repo.spring.io/milestone</url>
</pluginRepository>
</pluginRepositories>
</project>
文档内容从SpringBoot的文档拷贝
4、编制Application.java存于myFirstProject\src\main\java\com\example\myFirstProject下
package com.example.myFirstProject;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
5、编制Example.java,存于myFirstProject\src\main\java\com\example\myFirstProject下
package com.example.myFirstProject;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@EnableAutoConfiguration
public class Example {
@RequestMapping("/")
String home() {
return "Hello World!";
}
@RequestMapping("/hello/{myName}")
String index(@PathVariable String myName) {
return "Hello "+myName+"!!!";
}
}
二、Maven工程导入
1、启动eclipse
1.1、java–>jdk1.7.0_80x64
1.2、maven–>Apache Maven 3.3.3
1.3、Eclipse Java EE IDE for Web Developers. Version: Mars Release (4.5.0)
1.4、为本练习,新建一个workgroup
2、在eclipse中,依次点击file–>import–>Maven–>Existing Maven Projects–>Next–>Browse–>定位到myFirstProject文件夹–>确定–Finish
3、导入结果如图2
图2
三、运行
1、在eclipse的工程myFirstProject上右击鼠标,选择Run as–>Java Application,如图3
2、在select Java Aplication中选择“Application -com.example.myFirstProject”,如图4
图4
3、再次点击“OK”按钮,在Eclipse的Console中开始打印如图5
图5
4、打开浏览器,输入http://localhost:8080,显示如图6
5、在浏览器中,输入http://localhost:8080/hello/SpringBoot
四、后记
痛则不通,通则不痛。这个例子非常之简单,为了这个简单,费事不少。为了这个例子能够成功,最好做以下准备
1、构建本地的Maven伺服,否则速度痛苦
2、Sonatype Nexus尽量和jdk相对应的版本,不要最求最新,否则可能启动不起来。
3、Sonatype Nexus搭建,参考
