Where is my fault?How can i fix it?And I want to ask similar question.Sometimes we got some errors but i can't find it.So we understand this error's reason is pom.xml dependency conflicts.But no error on maven.We are tired because of incompatible dependency.Has it any solution of prevent dependency conflicts?(like maven dependency validator)

For using spring boot a easier way it's to create a Spring Boot project using Spring Initiliazr https://start.spring.io/. You can create from here a maven project that has the Spring Boot or more other dependencies alredeay patched in.

If you are just starting why don't you generate the project using https://start.spring.io/.
You added core Spring dependencies but not a single Spring Boot dependency. You only have a Spring Boot BOM and parent which only manage dependencies with <dependencyManagement>. You can inspect your dependencies by running mvn dependency:tree.

If you use Intellij Idea, you can resolve this problem in such way
Right-click on the folder of your project.
Choose "Add framework support".
Find "Maven" and set the checkbox.
After that, Intellij starts to download all dependencies.

#Valid #ModelAttribute not working properly

I have this controller
#Controller
public class EmpleadoController {
#Autowired
private EmpleadoService servicio;
#PostMapping("/empleado/new/submit")
public String nuevoEmpleadoSubmit(#Valid #ModelAttribute("empleadoForm") Empleado empleadoForm, BindingResult bindingResult) {
if(bindingResult.hasErrors()) {
return "formulario";
}else {
servicio.add(empleadoForm);
return "redirect:/empleado/list";
}
}
}
With this model
package com.alexotero.spring.model;
import javax.validation.constraints.Email;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotEmpty;
public class Empleado {
#Min(0)
private long id;
#NotEmpty
private String nombre;
#Email
private String email;
private String telefono;
//Constructors getters setters and stuff
I've also added this dependency to the pom.xml
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</dependency>
It doesn't matter what i introduce in the form, the controller never detects any error. Always adds the object to the List(in the service) and redirects to the list.html. I cannot find where is the problem.

For my case, I removed this dependency
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</dependency>
and added
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
I think they both conflict with each other.

#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 Spring Boot 2.1.2, pom.xml:

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.

I honestly don't understand you other questions (and you probably should ask them separately), but for question 2 I can tell you that a NoSuchMethodError is very likely to be caused by your using an incompatible version of Hibernate ORM with Hibernate Search.
To sum up:
Hibernate Search 5.7.0 and later should be used with Hibernate ORM 5.2.3 or later.
Hibernate Search 5.6.x and earlier should be used with Hibernate ORM 5.1.x or earlier.
EDIT: Your pom appears to contain a dependency to hibernate-entitymanager, and you didn't set the version for this dependency, so I suspect you're getting some older version. hibernate-entitymanager isn't required to use JPA starting with Hibernate ORM 5.2, so you should try to remove it.

"Caused by: java.lang.ClassNotFoundException: org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"
Please help me fix this exception. Thanks!!!

From your dependencies you missed (check you java version you use):
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.5.2.jre8-preview</version>
<scope>test</scope>
</dependency>
and into the application properties correct this line:
spring.datasource.driver-class- name=com.microsoft.sqlserver.jdbc.SQLServerDriver
to
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.jpa.hibernate.dialect=org.hibernate.dialect.SQLServer2012Dialect

Jersey cannot deserialize java.util.UUID out of String in request object

I have an endpoint which accepts a DriverJson class instance as http request payload. The DriverJson class has a property userId which is of type java.util.UUID.
The problem is that Jersey cannot deserialize UUID string into UUID object. When I debug and inspected driverJson, userId1 property is null (luckily it does not throw exception). I have read this article (article) that explains that classes that have fromString(String string) method (java.util.UUID has it) or have constructor with one (String) argument are deserialized by Jersey automatically (without writing any additional deserializer classes). If I change UUID type to String and I convert it my self (UUID.fromString(userId)) it's working perfectly.
In addition I use a #PathParam UUID arguments in some of my endpoints and they are working perfectly (as expected).
Below is my code:
My resource endpoint:
#POST
public Response add(DriverJson driverJson) {
DriverJson driver = service.add(driverJson);
return Response.status(Response.Status.CREATED).entity(driver).build();
}
My Driver class:
#XmlRootElement
public class DriverJson {
private UUID id;
private String name;
private UUID userId;
public DriverJson() {}
public DriverJson(UUID id, String name, UUID userId){
this.id = id;
this.name = name;
this.userId = userId;
}
/// getters & setters /////////
public UUID getId() {
return id;
}
public void setId(UUID id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public UUID getUserId() {
return userId;
}
public void setUserId(UUID userId) {
this.userId = userId;
}
}
My JSON request object:
{
"name" : "John",
"userId" : "ff06c5a4-135c-40b7-83f3-3648ec035efc"
}
I am using the standard Jersey archetype (version 2.23.2) with the following dependencies:
<dependencies>
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet-core</artifactId>
<!-- use the following artifactId if you don't need servlet 2.x compatibility -->

AFAIK you can fix it by using custom XmlAdapter:
public class UUIDAdapter extends XmlAdapter<String, UUID> {
#Override
public UUID unmarshal(String v) throws Exception {
return UUID.fromString(v);
}
#Override
public String marshal(UUID v) throws Exception {
return v.toString();
}
}
And then mark your fields with #XmlJavaTypeAdapter annotation
#XmlRootElement
public class DriverJson {
#XmlJavaTypeAdapter(UUIDAdapter.class)
private UUID id;
#XmlJavaTypeAdapter(UUIDAdapter.class)
private UUID userId;
/* ... */
}

Maven pom.xml Spring Boot does not exist - java

For using spring boot a easier way it's to create a Spring Boot project using Spring Initiliazr https://start.spring.io/. You can create from here a maven project that has the Spring Boot or more other dependencies alredeay patched in.

If you use Intellij Idea, you can resolve this problem in such way Right-click on the folder of your project. Choose "Add framework support". Find "Maven" and set the checkbox. After that, Intellij starts to download all dependencies.
