springBoot中使用使用junit测试文件上传,以及文件下载接口编写
本篇文章将介绍如何使junit在springBoot中测试文件的上传,首先先阅读如何在springBoot中进行接口测试.
文件上传操作测试代码
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.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.mock.web.MockMultipartFile;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.util.Date;
@RunWith(SpringRunner.class)
@SpringBootTest
public class BootStarterSecurityDemoApplicationTests {
@Test
public void contextLoads() {
}
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
/**
* 在每次测试执行前构建mvc环境
*/
@Before
public void setup() {
mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
/**
* 测试上传文件
*/
@Test
public void whenUploadFileSuccess() {
try {
String result = mockMvc.perform(
MockMvcRequestBuilders
.fileUpload("/file")
.file(
new MockMultipartFile("file", "test.txt", ",multipart/form-data", "hello upload".getBytes("UTF-8"))
)
).andExpect(MockMvcResultMatchers.status().isOk())
.andReturn().getResponse().getContentAsString();
System.out.println(result);
} catch (Exception e) {
e.printStackTrace();
}
}
}
编写文件下载接口
package com.micro.fast.security.demo.controller;
import org.apache.tomcat.util.http.fileupload.IOUtils;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
@RestController
@RequestMapping("/file")
public class FileController {
/**
* 处理文件上传
* @param file
*/
@PostMapping
public String upload(MultipartFile file){
File localfile = new File("/file/name");
try {
//将文件上传到本地路径
file.transferTo(localfile);
} catch (IOException e) {
e.printStackTrace();
}
String fileInfo = "";
fileInfo += file.getName()+file.getOriginalFilename()+file.getContentType();
return fileInfo;
}
/**
* 文件的下载
* @param id
* @param request
* @param response
*/
@GetMapping("/{id}")
public void download(@PathVariable String id , HttpServletRequest request, HttpServletResponse response){
try (InputStream inputStream = new FileInputStream(new File("/root/file/name"));
OutputStream outputStream = response.getOutputStream();
){
response.setContentType("application/x-download");
//指定文件的名称
response.addHeader("Content-Disposition","attachment;filename=test.txt");
IOUtils.copy(inputStream,outputStream);
outputStream.flush();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
