Hibernate throws such exception:
org.hibernate.QueryException: Expected positional parameter count: 2, actually detected 0
at org.hibernate.query.internal.QueryParameterBindingsImpl.verifyParametersBound(QueryParameterBindingsImpl.java:270)
at org.hibernate.query.internal.AbstractProducedQuery.beforeQuery(AbstractProducedQuery.java:1309)
at org.hibernate.query.internal.AbstractProducedQuery.list(AbstractProducedQuery.java:1408)
at org.hibernate.query.Query.getResultList(Query.java:146)
at pl.code.dao.PersonDAO.personExists(PersonDAO.java:59)
In this method:
#Override
public boolean personExists(String firstName, String location) {
TypedQuery<Person> query = entityManager.createQuery("Select p FROM Person p WHERE p.firstName = ? and p.location = ?", Person.class);
List<Person> all = query.getResultList();
return all.size() > 0 ? true : false;
}
I'm using Hibernate version 5.2.9.Final.
Any ideas what's wrong?
Please use this as the below example to pass in your paramters
Query q =session.createQuery("select u from User u where u.location=? and u.id in (:user_ids)");
q.setParameter(0, location);
q.setParameterList("user_ids", userIds);
return q.list();
I pass in parameters this way:
#Override
public synchronized boolean addPerson(Person person){
if (personDAO.personExists(person.getFirstName(), person.getLocation())) {
return false;
} else {
personDAO.addPerson(person);
return true;
}
}
and in controller
#RequestMapping(value= "/person", method = RequestMethod.POST)
public ResponseEntity<Void> addPerson(#RequestBody Person person, UriComponentsBuilder builder) {
boolean flag = personService.addPerson(person);
if (flag == false) {
return new ResponseEntity<Void>(HttpStatus.CONFLICT);
}
HttpHeaders headers = new HttpHeaders();
headers.setLocation(builder.path("/person/{id}").buildAndExpand(person.getPid()).toUri());
return new ResponseEntity<Void>(headers, HttpStatus.CREATED);
}

I want to prevent not logged user form accessing the proxy. I can throw an exception but the response is 404 instead of `401 or '403'. It it possible?
Filter code:
#Component
public class CustomZuulFilter extends ZuulFilter {
//FIXME - if 401,403 get the new token??, fallbackMethod = "fall",
#HystrixCommand(
commandProperties = {
#HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "5000"),
#HystrixProperty(name = "circuitBreaker.errorThresholdPercentage", value = "60")
}
)
#Override
public Object run() {
logger.debug("Adding zulu header");
String userName = getLoggedUser();
RequestContext ctx = RequestContext.getCurrentContext();
if (userName == null) {
// throw new RuntimeException("User not authenticated");
logger.info("User not authenticated");
ctx.setResponseStatusCode(401);
ctx.sendZuulResponse();
return null;
}
return null;
}
private String getLoggedUser() {
[...]
}
#Override
public boolean shouldFilter() {
return true;
}
#Override
public String filterType() {
return PRE_TYPE;
}
#Override
public int filterOrder() {
return PRE_DECORATION_FILTER_ORDER - 1;
}
}
It might be a bit late, but i think you can remove ctx.sendZuulResponse();
and add ctx.setSendZuulResponse(false);
I want to create dynamic query in spring data jpa. Doing many search I can implement it, but I came across a problem when I add IN operator in where clause. I need to check id IN (longlist)
Here is my entity class
#Entity
#Table(name = "view_detail")
public class ViewDetailDom {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
private String name;
#Column(name = "user_id")
private Long userId;
private String description;
Here is specification builder class and specification class
public class ViewDetailSpecificationsBuilder {
private final List<SearchCriteria> params;
public ViewDetailSpecificationsBuilder() {
params = new ArrayList<SearchCriteria>();
}
public ViewDetailSpecificationsBuilder with(String key, Operation operation, Object value) {
params.add(new SearchCriteria(key, operation, value));
return this;
}
public Specification<ViewDetailDom> build() {
if (params.size() == 0) {
return null;
}
List<Specification<ViewDetailDom>> specs = new ArrayList<Specification<ViewDetailDom>>();
for (SearchCriteria param : params) {
specs.add(new ViewDetailSpecification(param));
}
Specification<ViewDetailDom> result = specs.get(0);
for (int i = 1; i < specs.size(); i++) {
result = Specifications.where(result).and(specs.get(i));
}
return result;
}
}
public class ViewDetailSpecification implements Specification<ViewDetailDom> {
private SearchCriteria criteria = new SearchCriteria();
public ViewDetailSpecification(SearchCriteria searchCriteria) {
this.criteria.setKey(searchCriteria.getKey());
this.criteria.setOperation(searchCriteria.getOperation());
this.criteria.setValue(searchCriteria.getValue());
}
#Override
public Predicate toPredicate(Root<ViewDetailDom> root, CriteriaQuery<?> query, CriteriaBuilder builder) {
String value = criteria.getValue().toString().replaceAll(" ", "%");
if (criteria.getOperation() != null && criteria.getOperation() != Operation.DEFAULT) {
if (criteria.getOperation() == Operation.GREATHERTHANEQUALTO) {
return builder.greaterThanOrEqualTo(root.<String>get(criteria.getKey()), value);
} else if (criteria.getOperation() == Operation.LESSTHANEQUALTO) {
return builder.lessThanOrEqualTo(root.<String>get(criteria.getKey()), value);
} else if (criteria.getOperation() == Operation.EQUAL) {
return builder.equal(root.<String>get(criteria.getKey()), value);
} else if (criteria.getOperation() == Operation.IN) {
Path<Long> view = root.<Long>get(criteria.getKey());
return view.in(criteria.getValue());
}
} else {
if (root.get(criteria.getKey()).getJavaType() == String.class) {
return builder.like(builder.lower(root.<String>get(criteria.getKey())),
"%" + value.toLowerCase() + "%");
} else {
return builder.equal(root.get(criteria.getKey()), value);
}
}
return null;
}
}
This method creates specification builder:
public ViewDetailSpecificationsBuilder createSearchSpecifications(ViewSearch view) {
ViewDetailSpecificationsBuilder builder = new ViewDetailSpecificationsBuilder();
if (StringUtils.isNotBlank(view.getName())) {
builder.with("name", Operation.DEFAULT, view.getName());
}
if (StringUtils.isNotBlank(view.getDescription())) {
builder.with("description", Operation.DEFAULT, view.getDescription());
}
return builder;
}
And finally I do this:
ViewDetailSpecificationsBuilder builder = createSearchSpecifications(view);
builder.with("userId", Operation.DEFAULT, userSessionHelper.getUserId());
builder.with("id", Operation.IN, viewids);
Specification<ViewDetailDom> spec = builder.build();
viewDetailDao.findAll(spec);
But I am getting following error:
"Unaware how to convert value [[5, 7, 8] : java.util.ArrayList] to requested type [java.lang.Long]; nested exception is java.lang.IllegalArgumentException: Unaware how to convert value [[5, 7, 8] : java.util.ArrayList] to requested type [java.lang.Long]"
I have resolved this problem in this way:
ViewDetailSpecification class:
if (criteria.getOperation() == Operation.IN) {
final List<Predicate> orPredicates = new ArrayList<Predicate>();
List<Long> viewIds = (List<Long>) criteria.getValue();
for (Long viewid : viewIds) {
orPredicates.add(builder.or(builder.equal(root.<String>get(criteria.getKey()), viewid)));
}
return builder.or(orPredicates.toArray(new Predicate[orPredicates.size()]));
}
In kotlin I have the same error, I change the ArrayList to Array, with this code:
fun values(): Array<String> {
val elems = arrayListOf<String>()
return elems.toTypedArray()
}
Try you convert ArrayList to array, for java see: make arrayList.toArray() return more specific types
I am trying to apply Around advice to my "Login.jsp" with angular js. And the problem is my controller method is check and I am applying around advice to check method but when I run my application I will get undefined as response at Login.jsp. And but the result which I had printed in my advice contains expected result.But I am not getting it on client side.
AroundAdvice.java
#Aspect #Component
public class AroundAdvice {
static Logger log = Logger.getLogger(AfterLoginAspect.class.getName());
#Around("execution(* com.admin.controller.LoginController.check(..))")
public void logWrittter(ProceedingJoinPoint jp) throws Throwable {
SimpleDateFormat date=new SimpleDateFormat();
log.info("Date Time :: " + date.format(new Date().getTime()));
Object result = jp.proceed();
System.out.println("result around");
log.info("result :: " + result);
// returns {"get Status":"home"}
}
}
LoginController.jsp
// authentication check
#RequestMapping(value = "/PostFormData", method = RequestMethod.POST)
public #ResponseBody JSONObject check(#RequestBody LoginBo login) {
System.out.println("checkCredentials::" + login.getUserName());
String username = login.getUserName();
// log.info("uswername ::"+username);
JSONObject result = new JSONObject();
String encrptedpassword = encryptdPwd.encrypt(login.getPassWord());
boolean login_status = loginService.checkCredentials(username, encrptedpassword);
// log.info("login_status ::"+login_status);
// System.out.println("staus ::"+login_status);
if (login_status == true && login.isIs_system_generated_pwd() == true) {
System.out.println("sys gen chnge pwd:: " + login.isIs_system_generated_pwd());
result.put("getStatus", "change");
// System.out.println(resultPage);
// login.setIs_system_generated_pwd(false);
} else if (login_status == true && login.isIs_system_generated_pwd() == false) {
result.put("getStatus", "home");
// System.out.println("Home paege ");
} else {
result.put("getStatus", "error");
}
System.out.println("result ::" + result);
// log.info("result ::"+resultPage);
return result;
}
Your pointcut does not match because the advice has a void return type, but your method returns a JSONObject. So maybe you want to change your advice declaration to:
#Aspect #Component
public class AroundAdvice {
static Logger log = Logger.getLogger(AfterLoginAspect.class.getName());
#Around("execution(* com.admin.controller.LoginController.check(..))")
public JSONObject logWriter(ProceedingJoinPoint jp) throws Throwable {
SimpleDateFormat date=new SimpleDateFormat();
log.info("Date Time :: " + date.format(new Date().getTime()));
JSONObject result = (JSONObject) jp.proceed();
System.out.println("result around");
log.info("result :: " + result);
return result;
}
}
Please note
public JSONObject logWriter instead of public void logWrittter,
JSONObject result = (JSONObject) jp.proceed(); instead of Object result = jp.proceed(); and
return result; instead of no return value.
Can someone point out any mistake in my following code of Spring Jdbc Template?
When I click delete, the record is not getting deleted and there are no errors showing.
public void delete(String id) {
logger.debug("Deleting existing person");
// Prepare our SQL statement using Unnamed Parameters style
String query = "delete from person where id = ?";
// Assign values to parameters
Object[] person = new Object[] {id};
// Delete
jdbcTemplate.update(query, person);
}
Here is an example. Pay attention:
Integer id
public boolean delete(Integer id){
String sql = "DELETE FROM organization WHERE id = ?";
Object[] args = new Object[] {id};
return jdbcTemplate.update(sql, args) == 1;
}
#Override
public String deleteXXById(String id) {
String sql = "DELETE FROM VENUE WHERE id =:id?";
Map<String, Object> paramMap = new HashMap<String, Object>();
paramMap.put("id", id);
Object[] args = new Object[] {id};
int update = jdbcTemplate.update(sql, paramMap);
String updatecount = "Failed";
if (update == 0) {
updatecount = "Failed";
} else {
updatecount = "SUCCESS";
}
return updatecount;
}
I have a REST API that accepts 3 query params. When the query is called without any one of the query parameters, the API executes and returns the result. How do we make the queryparams mandatory? How can I add validation to check if all the parameters are present? Also, please let me know the best approach.
On a very simple level you could just inject the HttpServletRequest and check yourself:
#GET
public Response example(#Context HttpServletRequest request,
#QueryParam("name") String name) {
if (null == request.getParameter("name")) {
ResponseBuilder builder = Response.status(404);
return builder.build();
}
// Do something with name
}
Or you can implement something more elaborate using AOP. Here's a blog post about further options.
jersey doesn't give a mandatory parameter checking functionality out of the box. however you can do something like implementing your own annotation to achieve it.
Below is the annotation code:
#Target(value = ElementType.METHOD)
#Retention(value = RetentionPolicy.RUNTIME)
public #interface Required {
String[] value();
}
You also need a filter, below is the code:
public class RequiredParamResourceFilterFactory implements ResourceFilterFactory {
#Context
private transient HttpServletRequest servletRequest;
private class RequiredParamFilter implements ResourceFilter, ContainerRequestFilter {
private final String[] requiredParams;
protected List<String> parametersValueMissing;
private RequiredParamFilter(String[] requiredParams) {
this.requiredParams = requiredParams;
}
#Override
public ContainerRequest filter(ContainerRequest containerRequest) {
boolean missingMandatoryParameter = false;
List<String> missingParameters = new ArrayList<String>();
List<String> requiredParametersValueMissing = new ArrayList<String>();
List<String> URLParameters = getURLParameters(containerRequest.getQueryParameters());
List<String> methodRequiredParameters = Arrays.asList(requiredParams);
if (methodRequiredParameters != null) {
for (String methodRequiredParam : methodRequiredParameters) {
if (URLParameters == null) {
missingMandatoryParameter = true; //we will check this flag before returning result set to caller
missingParameters.add(methodRequiredParam);
} else if (!URLParameters.contains(methodRequiredParam)) {
missingMandatoryParameter = true; //we will check this flag before returning result set to caller
missingParameters.add(methodRequiredParam);
//Add to required parameters value missing List, only if the parameter is mandatory and value is not provided
// in the URL
} else if (parametersValueMissing.contains(methodRequiredParam)) {
requiredParametersValueMissing.add(methodRequiredParam);
}
}
if (missingMandatoryParameter && requiredParametersValueMissing.size() > 0) {
throw new YourCustomException("Missing Parameters = " + StringHelper.ArrayToString(missingParameters) +
"\nParameter value missing for " + StringHelper.ArrayToString(requiredParametersValueMissing));
} else if (missingMandatoryParameter) {
throw new YourCustomException("Missing Parameters = " + StringHelper.ArrayToString(missingParameters), MisbarErrorCode.VALIDATION_WRONG_INPUT_ERROR, "Customers");
} else if (requiredParametersValueMissing != null &&
requiredParametersValueMissing.size() > 0) {
throw new YourCustomException("Parameter value missing for " + StringHelper.ArrayToString(requiredParametersValueMissing));
}
}
return containerRequest;
}
#Override
public ContainerRequestFilter getRequestFilter() {
return this;
}
#Override
public ContainerResponseFilter getResponseFilter() {
return null;
}
/**
* To fetch the parameters sent to webservice call, these will be used to find if required parameter
* are present or not
*
* #param queryParams the queryparams sent
* #return all the parameters sent in URL
*/
private List<String> getURLParameters(MultivaluedMap<String,String> queryParams) {
parametersValueMissing = new ArrayList<String>();
List<String> arr = new ArrayList<String>();
for(String key:queryParams.keySet())
{
arr.add(key);
if(queryParams.get(key)==null)
parametersValueMissing.add(key);
}
if(!arr.isEmpty())
return arr;
return null;
}
}
#Override
public List<ResourceFilter> create(AbstractMethod am) {
Required required = am.getAnnotation(Required.class);
if(required!=null)
{
return Collections.<ResourceFilter>singletonList(new RequiredParamFilter(required.value()));
}
return null;
}
}
Below sample shows how to use this annotation, so in below webservice; file_id and count are mandatory parameters:
#GET
#Produces(MediaType.APPLICATION_JSON+";charset=utf-8")
#Cacheable(isCacheable = true)
#Path("posts/clusters")
#Required({"file_id","count"})
#Timed
public Response getClusters(
#QueryParam("file_id") Integer fileId,
#QueryParam("count") Integer count,
#DefaultValue("-1")#QueryParam("start_time") Long startTime){
;
}
If mandatory parameters are not provided in webservice call, you receive an error like below, mentioning the parameter names that are missing:
{
message: "Missing Parameters = file_id, count",
errorCode: "600"
}
Hope this solves your problem.
