i'm creating a controller of the entity "ChaineKO". In this controller i want to add a function which extract data from a file and add them to the DataBase. The extraction works but the recording in the DB does not.
#RestController
#CrossOrigin
public class ChaineKOContoller {
#Autowired
private ChaineKORepository chaineKORepository;
String pathToFile = "d:\\Profiles\\khbedoui\\Desktop\\Fichier_log__FDCALK2W-
41343.txt";
ChaineKO chaineKO;
#PostMapping("/ChaineKOAdd")
public void dataExtraction (String pathToFile){
try {
BufferedReader reader = new BufferedReader(new FileReader(new
File(pathToFile)));
String ligne;
while((ligne = reader.readLine()) != null){
if(ligne.contains("FP800BOP-BBAO0002-TRAVAIL TRAITE")){
String matricule = "";
matricule = ligne.substring(58);
chaineKO.setMatricule(matricule);
}
else if (ligne.contains("FP800BOP-BBAD0003-DEBUT DE
TRAITEMENT")) {
String date="";
date = ligne.substring(64);
chaineKO.setDate(date);
}
else if (ligne.contains("FP800BOP-BBAD0003-DEBUT DE
TRAITEMENT")) {
String nomChaine = "";
nomChaine = ligne.substring(7,11);
chaineKO.setNomChaine(nomChaine);
}
else if (ligne.contains("FIN ANORMALE")){
chaineKO.setEtat("NON TRAITE");
}
}
} catch (Exception ex){
System.err.println("Error. "+ex.getMessage());
}
chaineKORepository.save(chaineKO);
}}
And this is my class Repository :
#Repository
public interface ChaineKORepository extends JpaRepository<ChaineKO, Long> {
#Query("select e from ChaineKO e where e.nomLog like :x")
public Page<ChaineKO> chercher(#Param("x")String mc,Pageable pageable);
}
This is the response when i tested it with postman :
<h1>Not Found</h1>
<p>The requested URL /8080/ChaineKOAdd was not found on this server.</p>

Any Help please !!
I receive this error when I'm calling my endpoint which call Feign in the background :
com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of
`org.springframework.http.ResponseEntity` (no Creators, like default constructor, exist): cannot deserialize
from Object value (no delegate- or property-based Creator)
at [Source: (BufferedReader); line: 1, column: 2]
This is my endpoint inside Controller :
#RestController
#RequestMapping(Routes.URI_PREFIX)
public class CartoController {
#Autowired
private ReadCartographyApiDelegate readCartographyApiDelegate;
#GetMapping(value = "/cartographies/{uid}", produces = {MediaType.APPLICATION_JSON_VALUE})
public ResponseWrapper<ReadCartographyResponse> readCarto(HttpServletRequest request,
#PathVariable(name = "uid") String uid) {
ResponseEntity<ReadCartographyResponse> result ;
try {
result = readCartographyApiDelegate.readCartography(uid);
}catch (Exception e){
throw new TechnicalException("Error during read Carto");
}
return responseWrapperWithIdBuilder.of(result.getBody());
}
}
Interface ReadCartographyApiDelegate generated automatically by openApi from yaml file :
#javax.annotation.Generated(value = "org.openapitools.codegen.languages.SpringCodegen", date = "...")
public interface ReadCartographyApiDelegate {
default Optional<NativeWebRequest> getRequest() {
return Optional.empty();
}
default ResponseEntity<ReadCartographyResponse> readCartography(String uid) {
getRequest().ifPresent(request -> {
for (MediaType mediaType: MediaType.parseMediaTypes(request.getHeader("Accept"))) {
if (mediaType.isCompatibleWith(MediaType.valueOf("application/json"))) {
String exampleString = "null";
ApiUtil.setExampleResponse(request, "application/json", exampleString);
break;
}
}
});
return new ResponseEntity<>(HttpStatus.NOT_IMPLEMENTED);
}
}
This my ReadCartoApiDelegateImpl which implements ReadCartographyApiDelegate interface :
#Service
public class ReadCartographyApiDelegateImpl implements ReadCartographyApiDelegate {
private EcomGtmClient ecomGtmClient;
public ReadCartographyApiDelegateImpl(EcomGtmClient ecomGtmClient) {
this.ecomGtmClient = ecomGtmClient;
}
#Override
public ResponseEntity<ReadCartographyResponse> readCartography(String uid) {
ResponseEntity<ReadCartographyResponse> response = ecomGtmClient.readCartography(uid);
return response;
}
}
This is the feign client :
#FeignClient(name = "ecomGtmSvc", url = "http://localhost/")
public interface EcomGtmClient {
#GetMapping(value = "/read-carto/{uid}")
ResponseEntity<ReadCartographyResponse> readCartography(#PathVariable("uid") String uid);
}
The problem is that ResponseEntity (spring class) class doesn't contain default constructor which is needed during creating of instance. is there Any config to resolve this issue ?
If you want access to the body or headers on feign responses, you should use the feign.Response class. ResponseEntity does not work with feign because it is not meant to. I think it is best if you just return Response from your feign client method. You should then be able to pass the body to the ResponseEntity instance in the Controller.
What is your reason to even use the response-wrapper, i can't really figure that out from your code?
Sadly I couldn't find any documentation on the Response class, but here's the link to the source on GitHub.
https://github.com/OpenFeign/feign/blob/master/core/src/main/java/feign/Response.java
My Suggestion would be
#FeignClient(name = "ecomGtmSvc", url = "http://localhost/")
public interface EcomGtmClient {
#GetMapping(value = "/read-carto/{uid}")
ReadCartographyResponse readCartography(#PathVariable("uid") String uid);
}
#RestController
#RequestMapping(Routes.URI_PREFIX)
public class CartoController {
#Autowired
private ReadCartographyApiDelegate readCartographyApiDelegate;
#GetMapping(value = "/cartographies/{uid}", produces = {MediaType.APPLICATION_JSON_VALUE})
public ResponseWrapper<ReadCartographyResponse> readCarto(HttpServletRequest request,
#PathVariable(name = "uid") String uid) {
ReadCartographyResponse result ;
try {
result = readCartographyApiDelegate.readCartography(uid);
}catch (Exception e){
throw new TechnicalException("Error during read Carto");
}
// I don't know where you get the builder from, so I assume it does something import and is needed
return responseWrapperWithIdBuilder.of(result);
}
}
Of course you'd also have to change all intermediate classes.
The Response Output was the correct Object that I have to put, cause every time I need to check the status from my feign client endpoint to do différent logic
#FeignClient(name = "ecomGtmSvc", url = "http://localhost/")
public interface EcomGtmClient {
#GetMapping(value = "/read-carto/{uid}")
ReadCartographyResponse readCartography(#PathVariable("uid") String uid);
}
i have below resttempalte which invokes rest controller of another service..
#Override
public ResponseEntity<String> callRestAPI(APIReqDataMO apiReqDataMO) {
String apiURL = URIGenerator.getAPIURL(apiReqDataMO);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);
HttpEntity<?> request = new HttpEntity<>(apiReqDataMO.getRequestObject(), headers);
ResponseEntity<String> httpRes = restTemplate.postForEntity(apiURL, request, String.class);
return httpRes;
}
and in my service i have controller, which consumes above request..
#RequestMapping(value = "/targetService/createUser", method = RequestMethod.POST, consumes = "application/json")
public String fuzzerServiceAge(UserMO userMO) {
System.out.println("---------------------age is -------------------------" + userMO.getAge());
if (userMO.getAge() > 0) {
System.out.println("error age greater than 0 ");
return "invalid user age";
} else if (userMO.getAge() == 0) {
return "invalid user age";
}
return "user added successfully";
}
when i try my test.. the age which i am pushing through rest template is not getting mapped..and i am getting age as 0 always in my system.out.. what could be wrong in my code... and is there anything missing from configuration perspective..
EDIT -
public class APIReqDataMO {
private String restAPIURL;
private Object[] pathParam;
private Object[] requestParam;
private String requestType;
private String paramType;
private Object requestObject;
public String getParamType() {

#PostMapping("/targetService/createUser")

System.out.println("--------------------- age is -------------------------" + userMO.getAge());
if (userMO.getAge() > 0) {
// return ResponseEntity.ok("Hello World!");
} else if (userMO.getAge() == 0) {
System.out.println(" it is else block");
// return ResponseEntity.badRequest().build();
}
// return ResponseEntity.ok("user added successfully!");
return "user added successfully";
}
usermo
public class UserMO {
#JsonProperty("name")
private String name;
#JsonProperty("age")
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
Issue
There is an issue in API implementation. You are creating POST API and when the user will invoke this API by passing UserMO in the request body then mapping won't happen because the #RequestBody annotation is missing.
#PostMapping("/targetService/createUser")
public String fuzzerServiceAge(UserMO userMO) {
System.out.println("--------------------- age is -------------------------" + userMO.getAge());
if (userMO.getAge() > 0) {
// return ResponseEntity.ok("Hello World!");
} else if (userMO.getAge() == 0) {
System.out.println(" it is else block");
// return ResponseEntity.badRequest().build();
}
// return ResponseEntity.ok("user added successfully!");
return "user added successfully";
}
Solution
If you are using #RestController annotation on top of the controller class then add #RequestBody annotation before UserMO userMO and try again.
Like this
#PostMapping("/targetService/createUser")
public String fuzzerServiceAge(#RequestBody UserMO userMO) {
//logic
}
if you are using #Controller annotation on top of the controller class then add #ResponseBody annotation on top of method fuzzerServiceAge() and #RequestBody annotation before UserMO userMO and try again.
Like this
#PostMapping("/targetService/createUser")
#ResponseBody
public String fuzzerServiceAge(#RequestBody UserMO userMO) {
//logic
}
we need to make a spring boot project that works with spring ldap.
every things is good.But when we remove a member from a group,the member deleted form group (i see it in debug mode in a Setmembers) but, in ldap(Oracle Internet Directory) that member exists!
Please help me!
//Group Entry
#Entry(objectClasses = {"top", "groupOfUniqueNames", "orclGroup"}, base = "cn=Groups")
public final class Group {
#Id
private Name dn;
#Attribute(name = "cn")
private String name;
private String description;
private String displayName;
#Attribute(name = "ou")
private String ou;
#Attribute(name = "uniqueMember")
private Set<Name> members;
public void addMember(Name newMember) {
members.add(newMember);
}
public void removeMember(Name member) {
members.remove(member);
}
//Custom LdapUtils
public class CustomLdapUtils {
private static final String GROUP_BASE_DN = "cn=Groups";
private static final String USER_BASE_DN = "cn=Users";
public Name buildGroupDn(String name) {
return LdapNameBuilder.newInstance(GROUP_BASE_DN)
.add("cn","Charts")
.add("cn",name)
.build();
}
private static final CsutomLdapUtils LDAP_UTILS = new CsutomLdapUtils ();
private CsutomLdapUtils () {
}
public Name buildPersonDn(String name) {
return LdapNameBuilder.newInstance(USER_BASE_DN)
.add("cn", name)
.build();
}
}
//Controller
#DeleteMapping(value = "/memberOfGroup", consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> removeMemberFromGroup(#RequestBody Map<String,String> map) throws NamingException {
List<Group> groupToFind = ldapSearchGroupsService.getGroupByCn(map.get("groupName"));
List<User> userToFind = ldapSearchUserService.getAllUserByUserName(map.get("userName"));
if (groupToFind.isEmpty()) {
//TODO : Group no found!
return new ResponseEntity<>(HttpStatus.NO_CONTENT);
} else {
for (Group group1 : groupToFind) {
group1.removeMember(userToFind.stream().findAny().get().getDn());
//ldapBindGroupService.deleteMemberFromGroup(group1);
DirContextOperations ctx = ldapTemplate.lookupContext(CustomLdapUtils.getInstance().buildGroupDn(map.get("groupName")));
ctx.removeAttributeValue("uniqueMember",map.get("userName"));
ctx.rebind(CustomLdapUtils.getInstance().buildGroupDn(map.get("groupName")),map.get("groupName"));
ldapTemplate.modifyAttributes(ctx);
}
return new ResponseEntity<>(HttpStatus.OK);
}
}
Is some problem in code? or need some methods?
Finally after several search and debug,i found the problem!
In each ldap env,after every changes,the directory must be commit and apply.
In above code,i implemented that,but not in true way!
Best way is here:
#DeleteMapping(value = "/membersOfGroup", consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<?> removeMemberFromGroup(#RequestBody Map<String,String> map) {
List<Group> groupToFind = ldapSearchGroupsService.getGroupByCn(map.get("groupName"));
List<User> userToFind = ldapSearchUserService.getAllUserByUserName(map.get("userName"));
if (groupToFind.isEmpty()) {
//TODO : Group no found!
return new ResponseEntity<>(HttpStatus.NO_CONTENT);
} else {
for (Group group1 : groupToFind) {
group1.removeMember(userToFind.stream().findAny().get().getDn());
DirContextOperations ctx = ldapTemplate.lookupContext(CustomLdapUtils.getInstance().buildGroupDn(map.get("groupName")));
ctx.removeAttributeValue("member",CustomLdapUtils.getInstance().buildPersonDn(map.get("userName")));
//True way
ldapTemplate.update(group1);
}
return new ResponseEntity<>(HttpStatus.OK);
}
}
I want to make a rest webservice call :
#RestController
#RequestMapping("stock")
public class StockController {
#Autowired
private StockService stockService;
#GetMapping(value = "/TOM", produces = "application/json")
public JsonModel getByLocAndItm(#RequestParam(required=false) String LOC, #RequestParam(required=false) String ITM) {
JsonModel jsonModel = new JsonModel();
List<com.java.oxalys.beans.Stock> stock = stockService.getByLocAndItm(LOC.split("|"), null);
jsonModel.setDatas(stock);
return jsonModel;
}
}
service :
#Service
public class StockServiceImpl implements StockService {
#Autowired
private StockDao stockDao;
#Override
public List<com.java.oxalys.beans.Stock> getByLocAndItm(String[] locs, String[] itms) {
return stockDao.getByLocAndItm(locs, itms);
}
}
DAO :
#Repository
public class StockDaoImpl implements StockDao {
#Override
public List<Stock> getByLocAndItm(String[] locs, String[] itms) {
List<Stock> ret = new ArrayList<Stock>();
String where = "";
String where_locs = "", sep_locs = "";
for(String loc : locs) {
where_locs += sep_locs + " s.LOC_0 = '" + loc + "'";
sep_locs = " or ";
}
where_locs = "(" + where_locs + ")";
where = where_locs;
Stock tmp = new Stock();
tmp.setLoc("eto");
tmp.setItmoxa(where);
ret.add(tmp);
return ret;
}
}
At runtime with postman : localhost:8080/Oxalys_WS/stock/TOM?LOC=BOQSCM171L then I get error The resource identified by this request is able to generate responses only with features incompatible with the "accept" directive present in the request header
So what is wrong ?
I have created a database called student base on the tutorial provided by tutorials point PDF, they have covered how to map the form and insert values in to the database using controllers, but they have not explained how to display the data from the database on to the webpage.
My code to list all students.
#Override
public List<Student> listStudents() {
String SQL = "select * from Student";
List<Student> students = jdbcTemplateObject.query(SQL, new StudentMapper());
return students;
}
How to call this from my controller in spring and return the list to my webpage.
My contoller is given below
#Controller
public class StudentController {
#RequestMapping(value = "/student", method = RequestMethod.GET)
public ModelAndView student()
{
return new ModelAndView("student", "command", new Student());
}
#RequestMapping(value = "/addStudent", method = RequestMethod.POST)
public String addStudent(#ModelAttribute("SpringWeb")Student student, ModelMap model)
{
ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
StudentJDBCTemplate studentJDBCTemplate = (StudentJDBCTemplate)context.getBean("studentJDBCTemplate");
studentJDBCTemplate.create(student.getName(), student.getAge());
model.addAttribute("name", student.getName());
model.addAttribute("age", student.getAge());
model.addAttribute("msg", "Student Enrolled");
return "result";
}
// How to write the listing controller?
}
From the details you provide ,
public String ListStudents(ModelMap model)
{
List<Student> list= YourServiceClassObj.listStudents();
model.addAttribute("result", list);
return "View Name here";
}
public class AccountDAO {
Connection conn = null;
PreparedStatement ps = null;
ResultSet rs = null;
public Account getAll(String user, String pass) {
String query = "SELECT * FROM dbo.USERR WHERE username=? AND password =?";
try {
conn = new DBContext().getConnection();
ps = conn.prepareStatement(query);
ps.setString(1, user);
ps.setString(2, pass);
rs = ps.executeQuery();
while (rs.next()) {
return new Account(rs.getString(1),
rs.getString(2),
rs.getString(3));
}
} catch (Exception e) {
}
return null;
}
}
your controller and service methods should be like this .and then in the view use the controller returned attribute students.
#Controller
#RequestMapping(value = "/students", method = RequestMethod.GET)
public String students(ModelMap model)
{
List<Student> students= studentService.getStudents();
model.addAttribute("students", students);
return "student/studentList.html";
}
Service :
public interface StudentService {
List<Student> getStudents();
}
#Service
public class StudentServiceImpl implements StudentService {
#Override
public List<Student> getStudents() {
return studentRepository.findAll();
}
