Question

我在控制器中测试POST方法，该控制器通过MultipartFile处理图像上传。允许为空，但如果存在文件，则应将其上传。我写了一个单元测试，以确保它有效，但测试失败，返回404，我不知道为什么 - 可能是因为我不擅长阅读正在发生的事情。这是测试：

@Test
  public void saveAnEntryWhenPOSTNewUserWithAPicture() throws Exception {
    MockMultipartFile multiPFImage = new MockMultipartFile("ABCPicture", "abcpic.png",
            "img/png", "Generate bytes to simulate a picture".getBytes());
    mockMvc.perform(MockMvcRequestBuilders.fileUpload("/newcontact")
            .file(multiPFImage)
            .param("userId", "12345")
            .param("name", "Picture Uploader User"))
            .andExpect(status().isOk())
            .andExpect(content().string(containsString("savedContact")));
  }

这是运行该测试产生的堆栈跟踪：

编辑：

以下是正在测试的控制器方法：

@PostMapping(path = "/newContact")
  public String createNewContact(@ModelAttribute ContactDTO newContact) {
    Contact contact = new Contact(newContact.getUserId(), newContact.getName());
    setOptionalContactFields(contact, newContact);
    contactDAO.save(contact); // contactId automatically generated here (via SQL autoIncrement)
    newContact.setContactId(contact.getContactId()); // update the newContact to include the contactId
    if (newContact.getContactImg() !=null ) { 
      uploadContactProfileImg(newContact); // handles actual saving of image to persistence layer
    }

    return "savedContact"; // assumes template that can display all fields of a Contact will be returned
  }

非常感谢任何见解。

我发现您有错误类型public class ContactDTO { private MultipartFile conactImg; }

应为CREATE PROCEDURE [dbo].[IndexManagement] -- Parameters AS BEGIN SET NOCOUNT ON DECLARE @command nvarchar(max), @Satetement nvarchar(max) DECLARE @action varchar(15) IF OBJECT_ID('tempdb..#TableList') IS NOT NULL DROP TABLE #TableList CREATE TABLE #TableList ( ID INT IDENTITY ,DbName varchar(100) ,TableList nvarchar(100) ,IndexName nvarchar(500) ,SchemaName nvarchar(500) ,fragmentation float ) SET @Satetement =' INSERT INTO #TableList(DbName,TableList,IndexName,SchemaName,fragmentation ) SELECT DB_NAME(DB_ID()), dbtables.[name], dbindexes.[name], dbschemas.[name], CAST(avg_fragmentation_in_percent AS DECIMAL(18,2))avg_fragmentation_in_percent FROM sys.dm_db_index_physical_stats (DB_ID(), NULL, NULL, NULL, NULL) AS indexstats INNER JOIN sys.tables dbtables on dbtables.[object_id] = indexstats.[object_id] INNER JOIN sys.schemas dbschemas on dbtables.[schema_id] = dbschemas.[schema_id] INNER JOIN sys.indexes AS dbindexes ON dbindexes.[object_id] = indexstats.[object_id] AND indexstats.index_id = dbindexes.index_id WHERE indexstats.database_id = DB_ID() AND indexstats.avg_fragmentation_in_percent BETWEEN 5 AND 100 AND indexstats.index_id > 0 AND page_count > 1000 ' SELECT @command = 'IF ''?''

其他：您的DTO中存在拼写错误

{{1}}

请求多部分名称应与DTO相同， ABCPicture 应为 conactImg
