When I use Spring #Validated for validating I get a strange problem.
Here is the core code.
Java model:
#Getter
#Setter
public class User {
private String userName;
private String password;
private String email;
}
Custom UserValidate:
public class UserValidate implements Validator {
#Override
public boolean supports(Class<?> arg0) {
System.out.println("ee:"+arg0+","+User.class.isAssignableFrom(arg0));
return User.class.isAssignableFrom(arg0);
}
#Override
public void validate(Object target, Errors errors) {
//ValidationUtils.rejectIfEmpty(errors, "userName", "user.userName.required", "username can not be empty");
//ValidationUtils.rejectIfEmpty(errors, "password", "user.password.required", "password can not be empty");
//ValidationUtils.rejectIfEmpty(errors, "email", "user.email.required", "email can not be empty");
User user = (User) target;
int length = user.getUserName().length();
if (length > 20) {
errors.rejectValue("userName", "user.userName.too_long", "Username cannot exceed {20} characters");
}
length = user.getPassword().length();
if (length < 6) {
errors.rejectValue("password", "user.password.too_short", "Password is too short to be less than {6} characters");
} else if (length > 20) {
errors.rejectValue("password", "user.password.too_long", "Password is too long to be longer than {20} characters");
}
int index = user.getEmail().indexOf("#");
if (index == -1) {
errors.rejectValue("email", "user.email.invalid_email", "Bad mailbox format");
}
}
}
Thymeleaf form:
<html>
<head>
</head>
<body>
<br /><hr />
<form action="#" th:action="#{/addUser}" method="POST">
userName :<input type="text" name="userName" /><br />
password :<input type="text" name="password" /><br />
email :<input type="text" name="email" /><br />
result：<div style="font-size:18px;"><span th:text="${result}"></span></div>
<input type="submit" />
</form>
</body>
Controller:
import java.util.List;
import java.util.function.Consumer;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.validation.ObjectError;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.ModelAndView;
import com.example.demo.app.model.User;
import com.example.demo.app.validate.UserValidate;
import com.google.common.collect.ImmutableListMultimap;
import com.google.common.collect.ImmutableListMultimap.Builder;
#Controller
public class UserController {
#GetMapping("/userInfo")
public ModelAndView userInfo() {
ModelAndView userView = new ModelAndView("user");
return userView;
}
#PostMapping("/addUser")
public String addBook(#Validated User user,BindingResult result, Model model) {
if(result.hasErrors()){
List<ObjectError> allErrors = result.getAllErrors();
Builder<String, String> builder = ImmutableListMultimap.builder();
allErrors.stream().forEach(new Consumer<ObjectError>() {
#Override
public void accept(ObjectError t) {
builder.put(t.getObjectName(), t.getDefaultMessage());
}
});
ImmutableListMultimap<String, String> build = builder.build();
model.addAttribute("result",build);
}else {
model.addAttribute("result","success");
}
return "user";
}
#InitBinder
public void initBinder(WebDataBinder binder) {
binder.addValidators(new UserValidate());
}
}
After submitting, the exception is abnormal. The result of the exception is that the ImmutableListMultimap class also performs the validation process of UserValidate. Why does this happen?
exception stack:
ee:class com.example.demo.app.model.User,true
ee:class com.google.common.collect.ImmutableListMultimap,false

I'm trying to configure shiro redis session storage for vaadin spring boot app. but application failed whenever I try to set redisSessionDao to SessionMananger. application able to run if I remove redisSessionDao from SessionMananger but still can't persist session to redis. And also when I debug I save session is instance of DelegatingSubject$StopingAwareProxiedSession it should be SimpleSession, this caused Serializable issue when I try to save session manually using redisSessionDao.
Here is my configuration

Thank you everyone.
Thank you everyone.
Thank you everyone.
Thank you everyone.
Thank you everyone.
No need to write
#Autowired
private final ProductsRepository repo;
Since you are already injecting using constructor. You can simply autowire e.g.
public class YourController {
private final ProductsRepository repo;
public YourController(ProductRepository repo) {
this.repo = repo;
}
}
Put #Autowired on repo
#Autowired
private final ProductsRepository repo;
I have a new spring boot application that is attempting to make a soap call by extending Springs WebServiceGatewaySupport class, but receive "Unrecognised Callback" error.
I've tried modifying my getWebService method to use different varieties of getWebServiceTemplate implementations but continue to receive the error.
public class SOAPConnector extends WebServiceGatewaySupport {
public Object callWebService(String url, Object request) {
setInterceptor();
setMarshallerAndUnmarshaller();
// return getWebServiceTemplate().marshalSendAndReceive(url, request);
return getWebServiceTemplate().marshalSendAndReceive(
url, request, new WebServiceMessageCallback() {
#Override
public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
logger.info(message);
}
});
}
public void setInterceptor() {
Wss4jSecurityInterceptor interceptor = new Wss4jSecurityInterceptor();
interceptor.setSecurementActions("UsernameToken Timestamp");
interceptor.setSecurementUsername("username");
interceptor.setSecurementPassword("password");
interceptor.setSecurementUsernameTokenNonce(true);
this.setInterceptors(new ClientInterceptor[]{interceptor});
}
public Jaxb2Marshaller marshaller() {
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setContextPath("com.widget.api.job");
return marshaller;
}
public void setMarshallerAndUnmarshaller() {
this.setMarshaller(marshaller());
this.setUnmarshaller(marshaller());
}
}

Turns out this was a data related issue. For some reason the sever was returning back this generic message. Seems like it was doing some sort of validation or something, not absolutely sure. But I updated some of the info being passed and it's working now.
I have this basic application written in Spring Boot, with a Web Controller. I included a HTML form to add some input which will save the inputs using the JpaRepository save method.
I am using Thymeleaf as my templating engine and MySql as DB. When I run the app, it runs just fine. However, when i hit the page localhost:8080/addExpense, it gives a white label error page with the following error:
There was an unexpected error (type=Internal Server Error,
status=500).
Error during execution of processor 'org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor'
(template: "addExpense" - line 19, col 49)
I think the issue is with this code
th:field="*{expense}"
My IDE console prints the following error:
org.thymeleaf.exceptions.TemplateProcessingException: Error during
execution of processor
'org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor'
(template: "addExpense" - line 19, col 49) at
