SpringBoot

一、SpringBoot项目构建

1、通过SpringBoot的官方项目生成工具自动生成

可以从http://start.spring.io/这个网站上自动生成springboot基础项目的压缩包，解压缩后导入IDE

2、手动创建maven工程

二、服务开发

1、在src/main/java下建包，编写Controller：

package com.bin.cotroller;

 

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

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

 

@RestController

public class DemoController {

    @RequestMapping("/hello")

    public String helloSrpingBoot() {

        return "Hello Spring Boot";

    }

}

以clean spring-boot：run启动springBoot项目，然后在浏览器中通过Url：http://localhost:8080/hello访问，页面打印出 Hello Spring Boot；

三、单元测试

Spring的配置类

package com.bin.spring.config;

 

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.Configuration;

 

@Configuration//这是一个Spring的配置类

@ComponentScan(basePackages="com.bin.cotroller")//包扫描

public class SpringConfig {

 

}

 

测试类：

package com.bin.demo;

 

import static org.hamcrest.CoreMatchers.equalTo;

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

 

import org.junit.Before;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.boot.test.SpringApplicationConfiguration;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.http.MediaType;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import org.springframework.test.context.junit4.SpringRunner;

import org.springframework.test.context.web.WebAppConfiguration;

import org.springframework.test.web.servlet.MockMvc;

import org.springframework.test.web.servlet.MockMvcBuilder;

import org.springframework.test.web.servlet.MvcResult;

import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;

import org.springframework.test.web.servlet.setup.MockMvcBuilders;

 

import com.bin.cotroller.DemoController;

import com.bin.spring.config.SpringConfig;

 

@RunWith(SpringJUnit4ClassRunner.class)//引入spring对junit的支持

@SpringApplicationConfiguration(classes=SpringConfig.class)//springboot的启动类，spring的配置类

@WebAppConfiguration//开启web应用的配置@SpringBootTest

public class DemoApplicationTests {

    private MockMvc mvc;

    @Before

    public void setUp() throws Exception{

        mvc = MockMvcBuilders.standaloneSetup(new DemoController()).build();

    }

    @Test

    public void hello() throws Exception{

        mvc.perform(MockMvcRequestBuilders.get("/hello").accept(MediaType.APPLICATION_JSON))

        .andExpect(status().isOk())

        .andExpect(content().string(equalTo("Hello Spring Boot")));

    }

}
