Spring 5 In Action - Spring MVC Form Submit object always null where as the post method arguments are showing values

It's from Spring in Action ch03 JDBC
The taco object is always null.
Taco saved = designRepo.save(taco) throws null pointer exception
--updated as below, thanks JB Nizet --

How to change boolean value if checked with checkbox in thymeleaf?

I'm building weekly availability when a new user is registering. I'm using checkboxes to see what part of the day the user is available. For example if user is available on Monday until evening then user checks morning and evening under Monday.
th:field="${schedule.morning}" gives me and error.
th:name="${schedule.morning}" doesn't change the boolean value.
Schedule model
#NotNull
#NotEmpty(message = "Day of the availability is required.")
private String day;
#NonNull
#Column(nullable = false)
private boolean morning;
#NonNull
#Column(nullable = false)
private boolean afternoon;
#NonNull
#Column(nullable = false)
private boolean evening;
Controller
#GetMapping("/new-agent")
public String register(Model model) {
ScheduleHelper availability = new ScheduleHelper();
model.addAttribute("user", new User());
model.addAttribute("profile", new Profile());
model.addAttribute("schedules", availability);
model.addAttribute("languages", languages);
return "profile_reg";
}
#PostMapping("/new-agent")
public String registerNewUser(#Valid User user, BindingResult bindingResultUser,
#Valid Profile profile, BindingResult bindingResult,
ScheduleHelper schedules, BindingResult bindingResultSchedule,
Model model, RedirectAttributes redirectAttributes) {
if(bindingResult.hasErrors() || bindingResultUser.hasErrors() || bindingResultSchedule.hasErrors()) {
// Show validation errors.
logger.info("Errors registering a new user.");
model.addAttribute("validationErrors", bindingResult.getAllErrors());
model.addAttribute("validationErrorsUser", bindingResultUser.getAllErrors());
model.addAttribute("validationErrorsSchedule", bindingResultSchedule.getAllErrors());
model.addAttribute("user", user);
model.addAttribute("profile", profile);
model.addAttribute("schedules", schedules);
model.addAttribute("languages", languages);
return "profile_reg";
} else {
schedules.print();
// Register new user.
User newUser = userService.register(user);
profile.setUser(newUser);
Profile newProfile = profileService.register(profile);
for(int i = 0; i < 7; i++) {
Schedule newSchedule = schedules.getSchedule(i);
newSchedule.setProfile(newProfile);
scheduleService.register(newSchedule);
}
redirectAttributes

I want the program to change the boolean value from false to true when checkbox is checked.

According to the official thymeleaf documentation
http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#fixed-value-boolean-attributes
`th:checked is considered as a fixed-value Boolean attribute. So try like bellow.
<input type="checkbox" class="custom-control-input" th:checked="${schedule.morning}"
th:id="|morning-${schedule.day}|" />

Form Data Is Not Getting Validated Even If ExceptionHandler Is Defied

I'm implementing validation logic to the application. I have declared a class for custom validation logic. My class extends ResponseEntityExceptionHandler and overrides one method (handleMethodArgumentNotValid) to support #Valid and validate form data and I have some other methods for other exception propagation.
The problem I'm getting all custom exception is propagating to POSTMAN as JSON format but when I'm entering form data with wrong info it's ending with a java error and the overridden method is not getting called.
But I'm getting 200 as response and a blank data response not the validation error messages.
I have tried adding #Validated annotation along with #Valid annotation but it also didn't work.
I have added hibernate related validation annotation like #NotBlank(message=""), #NotNull(message="") in the pojo classes.
Though I'm getting the exception with the same message that I have provided in eclipse console but I'm not getting the desired response with the error messages in the postman.
Whenever I'm sending request from POSTMAN with incorrect form data and though #Valid annotation is there it should directly call the appropriate #ExceptionHandler annotated method but how it is propagating to the DAO with the null or incorrect values.

#RequestMapping("/emp")
public class EmployeeController {

try {
dtoo= service.insertEmp(dto);

}
return dtoo;
}

So you have the annotations on the ORM pojo and not on the DTO? How should Validation know what to validate?
You have to add the annotations to the DTO

Exception on sending multipart file request to eureka rest service end point

I am developing a file repository to store the pdf files. I am using eureka + spring boot which is in producer and consumer architecture. The client is having

Boolean.class);
callResponse = response.getBody();
}
} catch (Exception ex) {
ex.printStackTrace();

Now-a-days there are projects like Spring Content provide a very similar programming model for unstructured data (i.e. files, images, videos, etc) as Spring Data does for structured data. Plus it allows you to associate those files with your Entities.
So (assuming you are using Spring Boot) you would add the following dependencies:
pom.xml
<!-- Java API -->
<dependency>
<groupId>com.github.paulcwarren</groupId>
<artifactId>spring-content-fs-boot-starter</artifactId>
<version>0.4.0</version>
</dependency>
<!-- REST API -->
<dependency>
<groupId>com.github.paulcwarren</groupId>
<artifactId>spring-content-rest-boot-starter</artifactId>
<version>0.4.0</version>
</dependency>
Add the following attributes to your File entity so that content can be associated with it.
File.java
#Entity
public class File {
...existing fields...
#ContentId
private UUID contentId;
#ContentLength
private long contentLength = 0L;
// if you have rest endpoints
#MimeType
private String mimeType;
...
}
Create a ContentStore (the equivalent of your FileRepository but for your files):
FileContentStore.java
#StoreRestResource(path="fileContents")
public interface FileContentStore extends ContentStore<File, UUID> {
}
When you run your application Spring Content will see the FileContentStore interface and the spring-content-fs dependency and inject a Filesystem implementation of this interface for you. It will also see the spring-content-rest dependency and add an #Controller implementation that forwards GET, PUT, POST and DELETE REST requests onto FileContentStore as well. This saves you from having to write any of the controller code you have above. REST endpoints will be available at /fileContents so...
curl -X POST -F "image=#/path/to/local/file.pdf" /fileContents/{fileId}
will upload file.pdf and associate it with your file entity. And:
curl /fileContents/{fileId} will fetch it again.
This programming model also creates an abstraction over the file storage implementation allowing you to choose any type of storage that Spring Content supports (currently, this is Filesystem, S3, JPA BLOBs, Mongo's Gridfs and Google Storage). Your application code will stay the same regardless.

HTTP 500 error while trying to loop through a json array

I have a java RESTFUL webservice which gets a json array from my angular front end with HTTP POST. The json array is created dynamically inside a form with when you click a button to add more rows to the form, the weird thing is that if I submit with 1 row it works fine and adds the info to my database, but when I try with 2 rows or more I get the 500 error. Maybe my FOR loop to iterate on the json array is not the way it should be?
HTTP POST
postNeuromotora(params){
let headers = new Headers();
headers.append('Content-type','application/json');
return this.http.post(`${this.api}neuromotora/`,params,{
headers: headers
}).map(
(res:Response) => {return res.json();}
);
}
The json output that is send via http is this
"[ { "pacienteid": 4, "nervonome": "Mediano", "ladonervo": "Direito", "latencia": "2", "amplitudedistal": "1", "amplitudeprox": "321", "velocidade": "321", "ondaf": "4" }, { "pacienteid": 4, "nervonome": "Ulnar", "ladonervo": "Esquerdo", "latencia": "3", "amplitudedistal": "2", "amplitudeprox": "321", "velocidade": "312", "ondaf": "66" }]"
Neuromotora java file >
public class Neuromotora {
private int neuromotoraid;
private String latencia;
private String amplitudedistal;
private String amplitudeprox;
private String nervonome;
private String ladonervo;
private String velocidade;
private String ondaf;
private int pacienteid;
}
Insert method inside neuromotoraDAO
public void insert(List<Neuromotora> list) throws SQLException, ClassNotFoundException{
Long id = null;
for(Neuromotora n: list ){
String sqlQuery = "INSERT INTO neuromotora(nervonome,latencia,amplitudedistal,amplitudeprox,velocidade,ondaf,pacienteid,ladonervo)"
+ " VALUES(?,?,?,?,?,?,?,?)";
PreparedStatement stmt = this.con.getConnection().prepareStatement(sqlQuery);
stmt.setString(1,n.getNervonome());
stmt.setString(2,n.getLatencia());
stmt.setString(3,n.getAmplitudedistal());
stmt.setString(4,n.getAmplitudeprox());
stmt.setString(5,n.getVelocidade());
stmt.setString(6,n.getOndaf());
stmt.setInt(7,n.getPacienteid());
stmt.setString(8,n.getLadonervo());
ResultSet rs = stmt.executeQuery();
this.con.commit();
}
}
And the POST method at my java controller
#POST
#Consumes(MediaType.APPLICATION_JSON)
#Produces({MediaType.APPLICATION_JSON})
#Path("/neuromotora/")
public Response createNeuromotora(List<Neuromotora> n) throws SQLException, ClassNotFoundException{
