SpringBoot学习笔记（一）

学了springboot才知道以前的一大堆配置是多么的痛。废话不多说，将学习springboot过程中遇到的问题总结下

已知个人有两个spring boot的启动类

一、单元测试

package com.mkydy.springboot;

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.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@SpringBootTest(classes= com.mkydy.springboot.SpringBootFastjsonApplication.class)
@AutoConfigureMockMvc
public class UserControllerTest {

	
	@Autowired
	private MockMvc mvc;

	@Test
	public void exampleTest() throws Exception {
		this.mvc.perform(get("/")).andExpect(status().isOk())
				.andExpect(content().string("\"Greetings from Spring Boot!\""));
	}
}

1.和官网示例不同的是，@SpringBootTest注解需要配置classes，指定你自定义的启动类（是我有两个启动类的原因？）

另外，注意导入三个静态方法。不然看了其它教程会一脸懵逼。

2.string()中的字符串需要加转意字符，因为body的内容是纯字符串没有双引号包裹。

二、集成测试

package com.mkydy.springboot;

import java.net.URL;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.reactive.AutoConfigureWebTestClient;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.context.SpringBootTest.WebEnvironment;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.boot.web.server.LocalServerPort;
import org.springframework.http.ResponseEntity;
import org.springframework.test.context.junit4.SpringRunner;
/**
 * Spring Boot 集成测试
 * @author Mkydy
 *
 */
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT,classes=com.mkydy.springboot.SpringBootFastjsonApplication.class)
@AutoConfigureWebTestClient
public class HelloWorldTest {

	
	private URL base;
	
	@LocalServerPort
	private int port;
	
	@Autowired
	private TestRestTemplate template;
	
	@Before
    public void setup() throws Exception {
        this.base = new URL("http://localhost:" + port + "/");
    }
	
	@Test
    public void getHello() throws Exception {
        ResponseEntity<String> response = template.getForEntity(base.toString(), String.class);
        assert (response.getBody().equals("Greetings from Spring Boot!"));
    }
}

和官网不同的是需要加上@AutoConfigureWebTestClient注解，不然会报错，其次，还需要引入webflux jar包

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

var code = "979cb6e2-280c-4c7b-9501-71e946ea17f5"
