Send JSON Object from Postman to Restful webservices

Send JSON Object from Postman to Restful webservices - java

For exercise I'm trying to make a POST call on postman having the following classes but it always gives me an error that it cannot read the data.
The GET give me back the various users in the db and the commented POST where I go to create the new user manually (ie by setting the strings "blabla") works. I would like my POST to take a json object from the postman body
{
"username": "1",
"password": "2",
"email": "3"
}
and sending the request I enter the new user in the db. How can I do?
UserDB.java
public class UserDB {
public void insertUser(User user) {
EntityManager entityManager = JPAUtil.getEntityManagerFactory().createEntityManager();
EntityTransaction entityTransaction = entityManager.getTransaction();
entityTransaction.begin();
user.setUsername(user.getUsername());
user.setPassword(user.getPassword());
user.setEmail(user.getEmail());
entityManager.persist(user);
entityTransaction.commit();
}
User.java
#XmlRootElement(name = "user")
#XmlAccessorType(XmlAccessType.FIELD)
#Entity
#Table(name = "users")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "user_id")
private int user_id;
#Column(name = "username")
private String username;
#Column(name = "password")
private String password;
#Column(name = "email")
private String email;
public User() {
}
public User(int user_id, String username, String password, String email) {
this.user_id = user_id;
this.username = username;
this.password = password;
this.email = email;
}
public User(String username, String password, String email) {
this.username = username;
this.password = password;
this.email = email;
}
public int getUser_id() {
return user_id;
}
public void setUser_id(int user_id) {
this.user_id = user_id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String passoword) {
this.password = passoword;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
RestUser.java
#Path("/users")
public class RestUser {
private UserDB userDB;
public RestUser() {
this.userDB = new UserDB();
}
#GET
#Produces(MediaType.APPLICATION_JSON)
public String getUsers_JSON() {
String listUser = null;
List<User> list = userDB.selectAllUsers();
Gson gson = new Gson();
listUser = gson.toJson(list);
return listUser;
}
#GET
#Path("/{id}")
#Produces(MediaType.APPLICATION_JSON)
public String getUser_byid(#PathParam("id") int id) {
String u = null;
User user = userDB.selectUser_ID(id);
Gson gson = new Gson();
u = gson.toJson(user);
return u;
}
/*
#POST
#Produces(MediaType.APPLICATION_JSON)
public String message() {
String u = null;
Gson gson = new Gson();
User user = new User("user", "sss", "sss");
u = gson.toJson(user);
userDB.insertUser(user);
return u;
}
*/
#POST
#Path("/insert")
#Produces(MediaType.APPLICATION_JSON)
public void createUser(#QueryParam("username") String username,#QueryParam("password") String password,#QueryParam("email") String email) {
User newuser = new User(username, password, email);
userDB.insertUser(newuser);
}
}

In your controller method createUser you defined three query parameters for the user attributes instead of using the request body to receive the user data.
If you want to receive the user object as JSON in the request body try this:
#POST
#Path("/insert")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public void createUser(User user) {
userDB.insertUser(user);
}
Note the #Consumes annotation. When a HTTP POST request is sent to /users/insert (you could also leave /insert out, see below) the createUser method will be called and the JSON document with the user details will be converted into a Java object of the type User.
You can simplify it to:
#POST
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public void createUser(User user) {
userDB.insertUser(user);
}

Please help me to fix this,

Since you are using #ReuestParam you can't pass JSON like what you did.
In order to pass JSON format change #RequestParam to #RequestBody as below:
#PostMapping(path = "/add")
public #ResponseBody String addNewUser(#RequestBody User user){
// User n =new User();
//
// n.setName(name);
// n.setEmail(email);
// userRepository.save(n);
userRepository.save(user);
return "Saved";
}
And postman result would be as below:
But if you need to use #RequestParam then pass query string as below:
localhost:8811/demo/add?name=upul&email=upul#gmail.com

It seems that you have mixed up #RequestParam with #RequestBody
You seem to want to POST a JSON object to your controller, in which case your method signature should be
public #ResponseBody String addNewUser(#RequestBody User user){

Required String parameter 'name' is not present
Method parameters annotated with #RequestParam are required by default. It looks like while you are calling the API, you are not passing the name query param.
Edit: In this case, we could be passing the user in the request body.

#MockMvc does not work with validation annotated with #Valid

None of these solutions helped here: Spring mockMvc doesn't consider validation in my test. Added all of these dependencies, nothing helps.

I use standard hibernate validation '#NotNull':
#Entity
#Table(name="employee")
#JsonInclude(JsonInclude.Include.NON_NULL)
#JsonIgnoreProperties(ignoreUnknown = true)
public class Employee {
#Id
#Column
#GeneratedValue(strategy = GenerationType.IDENTITY)
protected Long id;
#NotNull(message = "Please provide name")
#Column(name = "name")
private String name;
#Column(name = "role")
private String role;
public Employee() {}
public Employee(String name, String role) {
this.name = name;
this.role = role;
}
}
#RestController
#RequestMapping(EmployeeController.PATH)
public class EmployeeController {
public final static String PATH = "/employees";
#Autowired
private EmployeeService service;
#PostMapping("")
public Employee newEmployee(#RequestBody #Valid Employee newEmployee) {
return service.save(newEmployee);
}
}
#Service
public class EmployeeService {
#Autowired
private EmployeeRepository repository;
public Employee save(Employee entity) {
return getRepository().save(entity);
}
}
#Repository
public interface EmployeeRepository extends JpaRepository<Employee, Long> {
}
Then I test my controller:
#RunWith(SpringRunner.class)
#SpringBootTest
#Transactional
#DatabaseSetup("/employee.xml")
#TestExecutionListeners({
TransactionalTestExecutionListener.class,
DependencyInjectionTestExecutionListener.class,
DbUnitTestExecutionListener.class
})
public class EmployeeControllerWebApplicationTest {
#Autowired
private WebApplicationContext context;
private MockMvc mockMvc;
private static String employeeRouteWithParam = EmployeeController.PATH + "/{id}";
#Before
public void setup() {
mockMvc = MockMvcBuilders
.webAppContextSetup(context)
.build();
}
#Test
public void create_WithoutName_ShouldThrowException() throws Exception {
String role = "admin";
Employee expectedEmployee = new Employee(null, role);
ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String json = ow.writeValueAsString(expectedEmployee);
ResultActions resultActions = this.mockMvc.perform(post(PATH)
.contentType(MediaType.APPLICATION_JSON_UTF8)
.content(json))
.andDo(print());
String contentAsString = resultActions.andReturn().getResponse().getContentAsString();
System.out.println("content: " + contentAsString); // empty body
resultActions
.andExpect(status().isBadRequest())
.andExpect(jsonPath("error").exists()) // not exist!!!
.andExpect(jsonPath("timestamp").exists()); // not exist!!!
}
}
employee.xml:
<dataset>
<Employee id="1" name="John" role="admin"/>
<Employee id="2" name="Mike" role="user"/>
</dataset>
I can not understand why it does not work when I test through #MockMvc. What am i doing wrong? Status is correct, but there is no error content, empty response
But validation works if tested on a really running application, then everything works.

#NotNull constraint is not working in Spring Boot

I am using Spring Boot and the #NotNull is not working. When the name value is not provided the function runs fine.
#Entity
public class Employee implements Serializable{
#Id
//#GeneratedValue(strategy=GenerationType.AUTO)
private int id;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
//#Id
public void setName(String name) {
this.name = name;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
#NotNull // not working
private String name;
private String phone;
}
the controller is
#Controller
public class URLController {
#Autowired
EmployeeServiceImpl empService;
#GetMapping({"/", "/index"})
public String index1(Model model){
model.addAttribute("employee",new Employee());
return "index";
}
#PostMapping("/result")
public String result(#Valid #ModelAttribute Employee employee){
System.out.print(employee.getName());
empService.save(employee);
return "result";
}
}

i am using the model attribute to get the employee object. the pom.xml file contains the hibernate validator dependency.

you must add #Valid annotaion in mapping part in your code for example
void addEmployee(#Valid Employee emp);
using this import "import javax.validation.Valid;"
Another note if you want to validate List you must make a wrapper list
Like
public class ValidList<E> implements List<E> {
#Valid
private List<E> list;}
And override all methods in it

Try modifying method like below to check details about errors.
#PostMapping("/result")
public String result(#Valid #ModelAttribute("employee") Employee employee, BindingResult bindingResult){
List<FieldError> errors = bindingResult.getFieldErrors();
for (FieldError error : errors ) {
System.out.println (error.getObjectName() + " - " +error.getDefaultMessage());
}
System.out.print(employee.getName());
empService.save(employee);
return "result";
}
If no error in bindingResult then refer notnull-constraint-not-working to troubleshoot further.

Any idea why this error is occurring?
If i do the post request to UserController the User object is saved in db and then that error occur.
The configurations are done correctly i think, dispatcher serlvet is configured extending AbstractAnnotationConfigDispatcherServletInitializer
EDIT:
When i stop the server the following warning appears:
WARNING: The web application [Example] appears to have started a thread named
[Abandoned connection cleanup thread] but has failed to stop it.
This is very likely to create a memory leak. Stack trace of thread:
java.lang.Object.wait(Native Method)
java.lang.ref.ReferenceQueue.remove(Unknown Source)
com.mysql.jdbc.AbandonedConnectionCleanupThread.run(AbandonedConnectionCleanupThread.java:43)

Please check your version of jackson dependecies on your pom.xml , try to change it :)

I got the same error with jackson data bind 2.7.1, updating the version to 2.7.1-1 solve the problem

I had same problem, I downgrade jackson-databind from 2.7.1 to 2.6.5 and(or) to 2.7.3 and it worked.

Spring-Data-Mongodb NoSuchMethodError when writing to db

I'm building a spring webapp using mongodb but recently I began having problems with writing to DB. The following stack trace is what I get.
SEVERE: Servlet.service() for servlet [DispatcherServlet] in context with path [/afcrowther_blog] threw exception [Handler processing failed; nested exception is java.lang.NoSuchMethodError: org.springframework.data.mongodb.core.mapping.MongoPersistentProperty.isWritable()Z] with root cause

After reading up the most common cause of this seems to be dependency mismatches, but I'm not sure which dependencies are actually compatible with one another in that case.

These are mainly the latest release versions, although I changed spring framework to 4.0.7.Release to try and fix it, but I have also used 4.1.0.Release and the same exception occurs.
Thanks

Update on the question, Upon changing to spring bom and spring data bom dependency management, the problem persisted.
However, removing the "#PersistenceConstructor" tag from the first constructor, and then switching around the order of the constructors fixed the issue. So the default constructor has to be first one in the file by the look of things. Not sure why, but there you go!
