java.lang.UnsupportedOperationException adding to a list [duplicate] - java

Arrays.asList give UnsupportedOperationException [duplicate]
(2 answers)
Closed 5 years ago.
I have some really strange problem. I want to call the method called create but unfortunately the server throws error, but I don't know why.
Here is my sample REST controller
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.*;
import pl.toby.model.User;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;
#RestController
#RequestMapping("/index")
public class HelloController {
private List<User> users;
public HelloController() {
users = Arrays.asList(
new User(1, "Jan", "Kowalski"),
new User(2, "Anna", "Nowak"),
new User(3, "Andrzej", "Przybylski"),
new User(4, "Maciej", "Adamczyk"),
new User(5, "Jacek", "Król")
);
}
// here is method, that I can create user
// i call it with /index/create request URI
#RequestMapping(value = "/create", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public List<User> create(#RequestBody User user) {
users.add(user);
return users;
}
}
And I cannot add user, because server throws the "Internal server error", but I don't know, why.
{
"timestamp": 1493548738275,
"status": 500,
"error": "Internal Server Error",
"exception": "java.lang.UnsupportedOperationException",
"message": "No message available",
"path": "/index/create"
}
EDIT
Ops. I forgot it. Here is my Tomcat error Log

You are using Arrays.asList method, here's what the Javadoc says:
Returns a fixed-size list backed by the specified array. (Changes to
the returned list "write through" to the array.) This method acts as
bridge between array-based and collection-based APIs, in combination
with Collection.toArray(). The returned list is serializable and
implements RandomAccess.
So, it returns a fixed size list, backed by the array. A list on which you can't perform add/remove operations (thats why UnsupportedOperationException is thrown). If you want to add or remove elements, try this:
users = new ArrayList<>();
users.add(new User(1, "Jan", "Kowalski"));
users.add(new User(2, "Anna", "Nowak"));
users.add(new User(3, "Andrzej", "Przybylski"));
users.add(new User(4, "Maciej", "Adamczyk"));
users.add(new User(5, "Jacek", "Król"));

It is not a Spring problem but how you initialize the Arraylist.
You can reproduce the problem with the code below
public static void main(String[] args) {
List<String> users = Arrays.asList(
"a","b"
);
users.add("c");
}
This happens because you are initializing the list as fixed one using the Arrays.asList and cannot be modified
Returns a fixed-size list backed by the specified array
If you modify how add the elements in the list you will be able to try the endpoint
Example:
users = new ArrayList<>();
users.add(new User(1, "Jan", "Kowalski"));
users.add(new User(2, "Anna", "Nowak"));
users.add(new User(3, "Andrzej", "Przybylski"));
users.add(new User(4, "Maciej", "Adamczyk"));
users.add(new User(5, "Jacek", "Król"));

I have written this code:
#RestController
public class UserController {
private final static Logger LOGGER = LoggerFactory.getLogger(UserController.class);
#RequestMapping(path = "/", produces = "application/json")
public #ResponseBody Principal getUser(HttpServletRequest request) throws Exception {
try {
Principal principal = request.getUserPrincipal();
LOGGER.debug("User found" + principal.toString());
return principal;
}
catch (Exception e) {
LOGGER.debug("User not found : " + e.getMessage());
throw e;
}
}
}
But it throws:
java.lang.IllegalStateException: getOutputStream() has already been
called for this response
How do I serialize that object? What makes an object serializable for Spring Boot? During the execution, the actual object type is the org.apache.catalina.realm.GenericPrincipal implementation of Principal

By exposing a Principal instance (such as an instance of GenericPrincipal from Apache Tomcat) in your web API, you may ended up leaking some sensitive details you don't intent to.
A better approach would be creating a DTO and then mapping only the principal details you want to expose to this DTO.
Despite the security breaches, let me just clarify what may be wrong with the serialization itself.
If you create an instance of GenericPrincipal and then attempt to serialize it to JSON using ObjectMapper directly, you'll see it won't succeed:
ObjectMapper mapper = new ObjectMapper();
Principal principal = new GenericPrincipal("john.doe", "secret", Arrays.asList("admin"));
String json = mapper.writeValueAsString(principal);
The exception is:
Exception in thread "main" com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Direct self-reference leading to cycle (through reference chain: org.apache.catalina.realm.GenericPrincipal["userPrincipal"])
If you check the GenericPrincipal source code, you'll see a userPrincipal field:
protected final Principal userPrincipal;
Well, you could attempt to use mix-in annotations, but it's probably not worth it. Just create a DTO and expose only what you need.

I am trying to write helloworld application using micro servise technique. In more details - I use spring cloud.
My hello world application interacts like this:
hello_service has single rest method:
#GetMapping("/hello")
public String hello(#RequestParam("name") String name) {
return "Hello " + name + "!";
}
hello_world_service uses hello_service and pass world as parameter
For routing I try to use ribbon+eurika. But I get following error:

Please help me to fix this issue.
P.S.
Full source code can be found here: https://github.com/gredwhite/spring-cloud

I found out that issue was related with service name hello_service.
In result of the URI parsing hello_service was a credentials. I fixed issue replacing hello_service with hello-service

The value is not set for parameter number 1 .; nested exception is
com.microsoft.sqlserver.jdbc.SQLServerException: The value is not set
to parameter number 1.
I see many tutorials and anwser about with use SimpleJdbcCall spring.
but no success, i am try this way, and have exception.
Other doubt, My parameter DUPLIC is a out parameter, how to use this out parameter in my code?
Obs: the database used is SQL Server
Edit: here's the procedure:
ALTER PROCEDURE [dbo].[AD_INSERT_ADIANTAMENTO_PARCELAS]
(#DATAVCM DATE,
#VALOR NUMERIC(18,2),
#MOTIVO INT,
#EMPRESA INT,
#NPARCELA INT,
#TOTALPARCELA INT,
#DOCUMENTO VARCHAR(100),
#FUNCIONARIO INT,
#HISTORICO VARCHAR(100),
#EXPORTAR INT,
#USUARIO INT,
#DUPLIC INT OUTPUT,
#PROTOCOLO VARCHAR(100))
AS
...

Here is the sample code.
declareParameters - Declare all input and output parameters of the
procedure. Use SqlOutParameter class for declaring the output
parameter
You can define DUPLIC as NUMBER (i.e. output parameter) and get the values using getInt.
Sample code:-
SimpleJdbcCall insertParcelas = new SimpleJdbcCall(jdbcTemplate)
.withSchemaName("dbo")
.withCatalogName("dbo")
.withProcedureName("AD_INSERT_ADIANTAMENTO_PARCELAS")
.declareParameters(
new SqlParameter("DATAVCM", OracleTypes.DATE),
new SqlParameter("VALOR", OracleTypes.VARCHAR),
....
new SqlOutParameter("DUPLIC", OracleTypes.NUMBER));
DateFormat fmt = new SimpleDateFormat("dd/MM/yyyy");
SqlParameterSource in = new MapSqlParameterSource()
.addValue("DATAVCM", new java.sql.Date(fmt.parse(arquivo.getVencimento()).getTime()))
.addValue("VALOR", arquivo.getValor())
.addValue("MOTIVO", arquivo.getCodMotivo())
.addValue("EMPRESA", arquivo.getCodEmpresa())
.addValue("NPARCELA", 1)
.addValue("TOTALPARCELA", 1)
.addValue("DOCUMENTO", arquivo.getDocumento())
.addValue("FUNCIONARIO", arquivo.getCodFunc())
.addValue("HISTORICO", "VALE IMPORTADO")
.addValue("EXPORTAR", 0)
.addValue("USUARIO", usuario.getCodigousuario())
.addValue("DUPLIC", 0)
.addValue("PROTOCOLO", "0");
Map<String, Object> out = insertParcelas.execute(in);
if (out != null && !out.isEmpty()) {
Sysout.out.println(out.getInt("DUPLIC"));
}

I have two request in same controller. I am using #InitBinder for validation in spring boot. My Controller is here.
#InitBinder
protected void initBinder(WebDataBinder webDataBinder) {
webDataBinder.setValidator(new FindPathValidator());
}
#PostMapping
public long addPath(#RequestBody #Valid PathResource resource) throws ResourceNotFoundException, DatabaseException {
}
#PostMapping(value = "find-all-path")
public FindPathResponse findAllPath(#RequestBody #Valid FindPathRequest resource) throws Exception {
}
My Validator is here
public class FindPathValidator implements Validator {
#Override
public boolean supports(Class<?> clazz) {
return FindPathRequest.class.equals(clazz);
}
#Override
public void validate(Object target, Errors errors) {
}

FindPathValidator.support() will throw exception when it is false. so we should limit the scope of #InitBinder to specific attribute:
#InitBinder("findPathRequest")
protected void initBinder(WebDataBinder webDataBinder) {
webDataBinder.setValidator(new FindPathValidator());
}

This question already has answers here:
How to use Jackson to deserialise an array of objects
(9 answers)
Closed 5 years ago.
I am trying to sort List of Object but it giving class cast exception. In Stacktrace it is showing that I am casting LinkedHashMap to Employee class. I am able to convert json to List object successfully but while sorting I am getting class cast exception.
#RequestMapping(value="/getAllEmployee/sortbyname",produces=MediaType.APPLICATION_JSON,consumes=MediaType.APPLICATION_JSON)
#ResponseBody
#POST
public String sortByName(#RequestBody String json) throws JsonMappingException, IOException{
logger.debug("Reached");
logger.debug(json);
List<Employee> list = JsonObjectConverter.mapFromJson(json.toString(), List.class); //converting to Object
logger.debug(list);
list.sort(new SortByName());
return JsonObjectConverter.mapToJson(list);
}
Here is my Comparator class
public class SortByName implements Comparator<Employee> {
#Override
public int compare(Employee emp1, Employee emp2) {
// TODO Auto-generated method stub
return emp1.getFirstName().compareTo(emp2.getFirstName());
}
}
This is the exception stacktrace I am getting
java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to org.ws.tutorial.model.Employee

Your mapFromJson method is returning a List containing LinkedHashMap objects as elements, instead of Employee objects. Such a list was capable of being assigned to a List<Employee> at runtime due to type erasure. Did you not get any compiler warnings about it?
The exception occurs when calling your comparator, which expects two Employee objects as arguments, but instead is passed LinkedHashMap objects.
You should check the Javadoc (or source code) of the mapFromJson method, and see what you need to do to obtain a List<Employee>.
