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.
