How to correct my code to remove CORS Problem to fetch?

Good afternoon!I get error "Access to fetch at 'http://localhost:8080/registration' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled."
I am trying to put information from web app angular, react into java app(spring boot). I looked many different links and did not find where the error in code is.
here is my Registration.js, I suppose there is a mistake, but cannot find where.
import fetch from "node-fetch";
class Registration extends Component{
constructor(props) {
super(props);
this.handleChange = this.handleChange.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
this.state = {
username: '',
password: '',
confirmPassword: '',
user_fullname: '',
user_email: '',
company_name: '',
position_name: '',
};
}
handleChange = (event, title) => this.setState({[title]: event.target.value});
handleSubmit = async event => {
event.preventDefault();
this.setState({isloading: true});
console.log(this.state);
const headers: HttpHeaders = new HttpHeaders().set('Content-Type', 'application/json;charset=UTF-8')
.append('Content-type', 'application/json;')
.append('Accept','application/json')
.append('Access-Control-Allow-Origin', '*')
return fetch('http://localhost:8080/registration',
{ mode:"no-cors" , headers: headers, method:"POST" ,body:this.state}
).then(response => {
console.log(response);
})
.catch(error => {
console.log(error)
})
};
render() {
return (

It seems like you have a problem with Spring Boot security. Assuming you have Spring Boot security enabled, based on the error message you've received "Response to preflight request doesn't pass access control check", you need to allow pre-flight request in the back-end. You can try to create a new class and extend WebSecurityConfigurerAdaptor like so:
#Configuration
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers(Http.OPTIONS, "/**").permitAll()
.anyRequest().authenticated()
.and()
.httpBasic();
}
}
Http.OPTIONS are pre-flight requests send to the server to make sure you have the right authentication to retrieve the resource. Here, you are permitting all pre-flight requests to let the actual request retrieve the resource.

Like #Andreas has Mentioned use #RequestBody instead of #ModelAttribute ( I believe #ModelAttribute annotation binds a method parameter) and also in client side you are posting that as JSON.
So try using below
#PostMapping(value = "/registration")
public String registration(#RequestBody User userForm, BindingResult bindingResult) {
//Code Logic
}

I believe #ModelAttribute only maps request parameters, i.e. values from query string or from form POST content with content type application/x-www-form-urlencoded or multipart/form-data.
Since you're sending the data as JSON, you need to change annotation to #RequestBody.

How to correctly bind form to #ManyToOne structure and save to DB. Spring MVC, Hibernate

I'm a novice java developer and now develop User Management application using Spring-Hibernate. I have two entities User and Email. And User entity has a field Email which is mapped to Email entity as #ManyToOne. Any Email can be used by multiple users.
When I save a new User in DB for every new user I get a new row Email, even if the same record is already in the Email Table. How to properly make save operation to avoid duplication of the same records in the table Email?
User.java
#Entity
#Table(name = "USER")
public class User implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="ID")
private Long id;
#Column(name = "name")
private String name;
#ManyToOne
#JoinColumn(name = "email_id")
private Email email;
public User(){
}
public Email getEmail() {
return email;
}
public void setEmail(Email email) {
this.email = email;
}
...
}
Email.java
#Entity
#Table(name = "EMAIL")
public class Email implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="ID")
private Long id;
#Column(name = "emailaddress")
private String emailaddress;
#OneToMany (mappedBy = "email", targetEntity=User.class)
private Set<User> user= new HashSet<User>();
public Email() {
}
public Email(String emailaddress) {
this.emailaddress = emailaddress;
}
public String getEmailaddress() {
return emailaddress;
}
public void setEmailaddress(String emailaddress) {
this.emailaddress = emailaddress;
}
...
}
Controller.java
#Transactional
#RequestMapping(value = "/adduser", method = RequestMethod.POST)
public String saveOrder(#ModelAttribute("user") User user, BindingResult result, #RequestParam String action){
emailDAO.create(user.getEmail());
userDAO.create(user);
return "index";
...
}
EmailDAO.java
#Transactional
#Repository
public class EmailDAO{
#Autowired
private SessionFactory sessionFactory;
public Email create(Email email) {
sessionFactory.getCurrentSession().save(email);
return email;
}
}
UserDAO.java
#Transactional
#Repository
public class UserDAO{
#Autowired
private SessionFactory sessionFactory;
public User create(User user) {
sessionFactory.getCurrentSession().save(user);
return user;
}
}
webform.jsp
<form:form action="${formUrl}" method="post" modelAttribute="user">
<form:label path="name" for="appname">username</form:label>
<form:input path="name" id= "appname" cssClass="form-control"/>
<form:label path="email.emailaddress" for="appemail">Email</form:label>
<form:input path="email.emailaddress" id= "appemail"/>
<button type="submit" name="action" value="Add">Save</button>
</form:form>
database diagram
Example of the DB records

That is because you keep on saving the Email as a new Record
#Transactional
#RequestMapping(value = "/adduser", method = RequestMethod.POST)
public String saveOrder(#ModelAttribute("user") User user, BindingResult result, #RequestParam String action){
emailDAO.create(user.getEmail()); // Inserting Email as New Record
userDAO.create(user);
return "index";
...
}
And you don't have unique=true on Email Entity
#Column(name = "emailaddress", unique = true)
private String emailaddress;
Which you should ideally have so that there will be no duplicate Emails will get inserted even by accidentally.
You need to modify EmailDAO
#Transactional
#Repository
public class EmailDAO{
#Autowired
private SessionFactory sessionFactory;
public Email create(Email email) {
sessionFactory.getCurrentSession().save(email);
return email;
}
public Email getEmail(String inputEmail) {
Email email = null;
Query query = sessionFactory.getCurrentSession().createQuery("FROM Email e WHERE e.emailaddress = :email");
query.setString("email", inputEmail);
List emails = query.list();
if(emails != null && emails.size() > 0) {
email = (Email)emails.get(0);
} else {
email = new Email();
email.setEmailAddress(inputEmail);
}
return email;
}
}
And you getEmail
#Transactional
#RequestMapping(value = "/adduser", method = RequestMethod.POST)
public String saveOrder(#ModelAttribute("user") User user, BindingResult result, #RequestParam String action){
user.setEmail(emailDAO.getEmail(user.getEmail().getEmailAddress())); // Inserting Email as New Record
userDAO.create(user);
return "index";
...
}

Don't allow the user to save data in mysql database if the input is incorrect

First, you shouldn't modify any .aj because Spring Roo will overwrite your changes next time you run it. To customize your field you have to move its declaration into related .java file (we call it push-in).
To set the field validation, Roo uses the JSR-303 specification, using the Hibernate validation as implementation.
So, to archive it, try:
Push-in the phone declaration into User.java and add javax.validation.constraints.Size annotation:
public class User {
#Column(name = "phone", length = 10, unique = true)
#NotNull
#Size(max=10,min=10)
private String phone;
}
Run Spring Roo console.
After that, Roo will:
remove phone definition from User_Roo_DbManaged.aj
create the getter and setter on User_Roo_bean.aj
Update User related .jspx
Note that #Column definition refers to database declaration. Any other field validation you should use the javax.validation.constraints.* annotations or create yours (here you have an example)
Good luck!

I was able to successfully deploy the web service and then i added a new Restful web client using netbeans, which created the following class
public class Client {
private WebTarget webTarget;
private javax.ws.rs.client.Client client;
private static final String BASE_URI = "http://localhost:31691/ProductionEntitiesService/api";
public Client() {
client = javax.ws.rs.client.ClientBuilder.newClient();
webTarget = client.target(BASE_URI).path("entities.users");
}
...
public <T> T find_XML(Class<T> responseType, String id) throws ClientErrorException {
WebTarget resource = webTarget;
resource = resource.path(java.text.MessageFormat.format("{0}", new Object[]{id}));
return resource.request(javax.ws.rs.core.MediaType.APPLICATION_XML).get(responseType);
}
public <T> T findAll_XML(Class<T> responseType) throws ClientErrorException {
WebTarget resource = webTarget;
return resource.request(javax.ws.rs.core.MediaType.APPLICATION_XML).get(responseType);
}
public void close() {
client.close();
}
}
This line of code then returned an xml result of the query
result = c.findAll_XML(String.class);
which had this format
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<userss>
<users>
<userCategoryId>
<categoryId>2</categoryId>
<userCategory>admin</userCategory>
</userCategoryId>
<userName>admin</userName>
<userPassword>d033e22ae348aeb5660fc2140aec35850c4da997</userPassword>
</users>
</userss>
However, this line of code
List<Users> l = (List<Users>)c.findAll_XML(Users.class);
produces an exception, which seems to be caused by the "userss" tag that surrounds the xml result, I'm not sure how that came about.
Can anyone help me resolve this?

Hi I am new to Spring Mvc i have 3 tables first is role,resources,roleresource tables respectively. I have a created a jsp in which a list of resources are shown along with check boxes and also rolename where user enters,my prob is i need to insert rolename to role table and generated roleid to roleresource table with selected resources ids. problem here is i am not able to bind selected checkbox values here is my controller
package com.steadyground.controller;

here is my role.java file

here is my resources.java

}
public void setUrlName(String urlName) {

}
here is my roleresource.java

</div>
</div>
</div>
</springform:form>
could someone help me in how to receive the data and save it in two tables

<springform:checkboxes path="resources" items="${resources}" itemLabel="urlName" itemValue="resourceId"/>
From your code, what I've understood, the RoleResourcesForm is more like a wrapper of the 2 entities Resource & Role with another object resources.
I think, to use form:checkboxes you better give it an object List in the path.
And what's this variable resources?
If it's really an List object in the RoleResourcesForm wrapper, in the items, you should use
items="${roleResourceForm.resources}"
When you commit it, it will send the form model attribute with only checked checkbox values.
