Spring Boot 是由Pivotal團(tuán)隊(duì)提供的全新框架恐疲，其設(shè)計(jì)目的是用來簡化新Spring應(yīng)用的初始搭建以及開發(fā)過程。該框架使用了特定的方式來進(jìn)行配置衔瓮，從而使開發(fā)人員不再需要定義樣板化的配置。通過這種方式，Spring Boot致力于在蓬勃發(fā)展的快速應(yīng)用開發(fā)領(lǐng)域(rapid application development)成為領(lǐng)導(dǎo)者姥饰。

下面，我們先做個(gè)簡單的樣例：

一孝治、新建項(xiàng)目

新建maven項(xiàng)目springboot-bucket-mine列粪，然后再其下新建module springboot-base，建完后目錄如下圖所示

項(xiàng)目搭建 1

二谈飒、引入依賴

• 打開springboot官網(wǎng)https://projects.spring.io/spring-boot岂座，點(diǎn)擊QUICK START，可以看到如下圖所示
  

  項(xiàng)目搭建 2

• 如上圖所示杭措，我們在父pom.xml中加入如下代碼

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.2.RELEASE</version>
    </parent>

• 在子pom.xml加入

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

三费什、新建restController

代碼如下

package com.springboot.my.controller;

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

@RestController
public class HelloController {

    @RequestMapping("/")
    public String index(){
        return "Greetings from Spring Boot!";
    }
}

四、新建啟動類

代碼如下

package com.springboot.my;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class BaseApplication {
    public static void main(String[] args) {
        SpringApplication.run(BaseApplication.class, args);
    }
}

五手素、啟動&驗(yàn)證

執(zhí)行BaseApplication.java中的main方法鸳址，控制臺啟動日志和接口驗(yàn)證如下

啟動

接口驗(yàn)證

五瘩蚪、Junit Test

• 新增依賴

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

• 編寫測試代碼

package com.springboot.my;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;

import static org.hamcrest.Matchers.equalTo;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class HelloControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void helloTest() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/").accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk())
                .andExpect(content().string(equalTo("Greetings from Spring Boot!")));
    }
}
