第一个SpringBoot测试实例

1.SpringBoot项目构建：http://start-spring.io   自动化构建SpringBoot项目，保存在本地并解压

2.安装gradle并配置gradle环境

3.配置阿里云maven仓库：修改gradle.build 里面额maven仓库，改为：maven{  url 'http://maven.aliyun.com/nexus/content/groups/public'  }

4.构建项目，进入解压后的项目路径下，打开控制台执行以下命令：cmd -> cd E:/hello ->E:  ->  gradle build  ->java -jar build/libs/xxxxx.jar

5.导入开发工具，进行测试，测试代码如下：

在main目录下，新建HelloController类：

package com.waylau.spring.boot.blog.controller;

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

@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String hello(){
        return "Hello World!";
    }
}

在test下，新建HelloControllerTest类：

package com.waylau.spring.boot.blog.contrller;

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 testHello() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/hello").accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk())
                .andExpect(content().string(equalTo("Hello World!")));
    }

}
