问题描述
我已成功将图像文件上传到 WebContent\resources\uploads\image.jsp 。但我在使用MockMvc测试时遇到了问题。当我运行测试用例时，我收到文件未找到和访问被拒绝的例外。
I have successfully uploaded a image file to WebContent\resources\uploads\image.jsp. But I am facing a problem in testing this using MockMvc. When I run the test case I am getting the exceptions file not found and access denied.
控制器看起来像这样：
@RequestMapping(value="/AddContacts", method=RequestMethod.POST)
public @ResponseBody String addContacts(ContactBean cb,HttpServletRequest request,HttpServletResponse response,@RequestParam("upload") MultipartFile file) throws IllegalStateException, IOException
{
String error=cb.validate();
if(error.equals("")){
Model m=new Model();
String ret=m.addData(cb);
System.out.println("Contact Bean: "+cb);
if(ret.equals("DBFAIL")){
response.setStatus(500);
}
else if(ret.equals("EXIST")){
response.setStatus(409);
}
else{
response.setStatus(200);
/* to upload a file */
if(file != null && file.getSize() > 0){
System.out.println("File name: "+file.getOriginalFilename());
String dir="C:\\web_latest\\Admin_FileUpload_29_01_15\\WebContent\\resources\\uploads\\"+cb.getName()+"_"+cb.getId()+"\\";
//String dir="C:\\Upload\\"+cb.getName()+"_"+cb.getId()+"\\";
File directory = new File(dir);
if (directory.exists()) {
System.out.println("Directory already exists ...");
}
else {
System.out.println("Directory not exists, creating now");
boolean success = directory.mkdir();
if (success) {
System.out.printf("Successfully created new directory : %s%n", dir);
}
else {
System.out.printf("Failed to create new directory: %s%n", dir);
}
}
String fileName = file.getOriginalFilename();
file.transferTo(new File(dir+fileName));
}
}
return error;
}
else{
//response.setStatus(500);
return error;
}
}
我的测试用例如下：
public void testAddContacts() throws Exception {
FileInputStream fis=new FileInputStream("C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg");
//MockMultipartFile upload = new MockMultipartFile("upload", "Penguins.jpg", "image/jpeg", "C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg\\".getBytes());
MockMultipartFile upload= new MockMultipartFile("upload",fis);
MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
mockMvc.perform(MockMvcRequestBuilders.fileUpload("/AddContacts")
.file(upload)
.param("some-random", "4")
.param("name","deerdad")
.param("email","niharik@gmail.com")
.param("phone", "1234567890"))
.andExpect(status().is(200));
}
我的jsp文件是这样的：
My jsp file is like this:
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

var email = $('#email').val();

var file = document.getElementById("uploadfile");
var formData = new FormData();
formData.append("upload", file.files[0]);
formData.append("name",$('#name').val());
formData.append("email",$('#email').val());
formData.append("phone",$('#phone').val());
$.ajax({

success: function(response){
$("#error").text("");
if(response==""){
$("#info").text("successfully added");
$('#myTable').append("<tr><td><input type='checkbox' name='cb' value='"+ response+"'><td>"+name + "</td><td>"+email + "</td><td>"+phone + "</td></tr>");
$("#addForm").hide();
}
else{
$("#info").text(response);
}
},
error: function(){

$("#error").text("Internal server error");
},
statusCode: {

}
}
});
}

推荐答案
public void testAddContacts() throws Exception{
File f = new File("C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg");
System.out.println(f.isFile()+" "+f.getName()+f.exists());
FileInputStream fi1 = new FileInputStream(f);
FileInputStream fi2 = new FileInputStream(new File("C:\\Users\\Public\\Pictures\\Sample Pictures\\Tulips.jpg"));
MockMultipartFile fstmp = new MockMultipartFile("upload", f.getName(), "multipart/form-data",fi1);
MockMultipartFile secmp = new MockMultipartFile("upload", "Tulips.jpg","multipart/form-data",fi2);
MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
mockMvc.perform(MockMvcRequestBuilders.fileUpload("/AddContacts")
.file(fstmp)
.file(secmp)
.param("name","abc").param("email","abc@gmail.com").param("phone", "1234567890"))
.andExpect(status().isOk());
}
