概述
@SpringBootTest注解是SpringBoot自1.4.0版本开始引入的一个用于测试的注解。基本用法如下:
1.添加依赖:

package com.cxh.test; import java.net.URL; import java.util.List; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.context.embedded.LocalServerPort; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.boot.test.web.client.TestRestTemplate; import org.springframework.http.ResponseEntity; import org.springframework.test.context.junit4.SpringRunner; import com.cxh.study.platform.GeneratorApp; import com.cxh.study.platform.entity.User; /** * * @desciption 用户管理测试类 * @author ChenXiHua * @date 2019年2月19日 * */ @RunWith (SpringRunner. class ) @SpringBootTest (classes = GeneratorApp. class , webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class UserTest { /** * @LocalServerPort 提供了 @Value("${local.server.port}") 的代替 */ @LocalServerPort private int port; private URL base; @Autowired private TestRestTemplate restTemplate; @Before public void setUp() throws Exception { String url = String.format( "http://localhost:%d/" , port); System.out.println(String.format( "port is : [%d]" , port)); this .base = new URL(url); } /** * 向"/test"地址发送请求,并打印返回结果 * @throws Exception */ //@Test public void test1() throws Exception { ResponseEntity<String> response = this .restTemplate.getForEntity( this .base.toString() + "/test" , String. class , "" ); System.out.println(String.format( "测试结果为:%s" , response.getBody())); } //@Test public void getAllTest() throws Exception { ResponseEntity<List> response = this .restTemplate.getForEntity( this .base.toString() + "/getAll" , List. class , "" ); System.out.println(String.format( "测试结果为:%s" , response.getBody())); } @Test public void getUserByIdTest() throws Exception { ResponseEntity<User> response = this .restTemplate.getForEntity( this .base.toString() + "/getUserById?id=1" , User. class , "" ); System.out.println(String.format( "测试结果为:%s" , response.getBody().toString())); } } |
其中,classes属性指定启动类,SpringBootTest.WebEnvironment.RANDOM_PORT经常和测试类中@LocalServerPort一起在注入属性时使用。会随机生成一个端口号。
7.测试结果:
