我正在使用Springboot作为我的Web应用程序。有一个API端点使用多部分csv文件。我应该读取此文件，然后将其映射到我的用户java类，然后将其存储在数据库中。 我的控制器类
@PostMapping(value = "/students" ,consumes = {"multipart/form-data"})
public void registerStudents(@Valid @RequestParam("file") MultipartFile file) throws Exception{
if(file.isEmpty())
throw new Exception("File is Empty!");
registrationService.registerStudents(file);
}
我的RegistrationService类
public void registerStudents(MultipartFile file) throws IOException {
CsvToBean<PlatformUser> csvToBean = new CsvToBean<PlatformUser>();
HeaderColumnNameMappingStrategy<PlatformUser> strategy = new HeaderColumnNameMappingStrategy<PlatformUser>();
strategy.setType(PlatformUser.class);
File convertedFile = new File(Objects.requireNonNull(file.getOriginalFilename()));
file.transferTo(convertedFile);
CSVReader csvReader = new CSVReader(new FileReader(convertedFile));
List<PlatformUser> userList = csvToBean.parse(strategy,csvReader);
}
我的csv文件是
FIRST NAME,MIDDLE NAME,LAST NAME
Rajeev,K,Hegde
我的PlatformUser类是
@CsvBindByName(column = "FIRST NAME", required = true)
private String firstName;
@Size(max = 30)
@CsvBindByName(column = "MIDDLE NAME")
private String middleName;
@Size(max = 30)
@CsvBindByName(column = "LAST NAME", required = true)
private String lastName;
以下是我的邮递员对我的api电话的回复
{
"timestamp": "2018-05-01T13:21:27.882+0000",
"status": 500,
"error": "Internal Server Error",
"message": "org.apache.commons.lang3.reflect.FieldUtils.getAllFields(Ljava/lang/Class;)[Ljava/lang/reflect/Field;",
"path": "/api/v1/registration/students"
}
当我尝试调试我的应用程序时，我发现了一行strategy.setType（PlatformUser.class）;在RegistrationService中抛出错误 java.lang.reflect.InvocationTargetException 为了清晰的图片添加我的stacktrace
java.lang.NoSuchMethodError: org.apache.commons.lang3.reflect.FieldUtils.getAllFields(Ljava/lang/Class;)[Ljava/lang/reflect/Field;
