How to insert into db in spring-data?

Question

I want to make a request that inserts data into my database. The table has 4 columns: ID_DOCUMENT (PK), ID_TASK, DESCRIPTION, FILEPATH

Entity

... 
@Column(name = "ID_TASK")
private Long idTask;


@Column(name = "DESCRIPTION")
private String description;

@Column(name = "FILEPATH")
private String filepath;
...

Repository

@Modifying
@Query("insert into TaskDocumentEntity c (c.idTask, c.description, c.filepath) values (:id,:description,:filepath)")
public void insertDocumentByTaskId(@Param("id") Long id,@Param("description") String description,@Param("filepath") String filepath);

Controller

@RequestMapping(value = "/services/tasks/addDocument", method = RequestMethod.POST)
@ResponseBody
public void set(@RequestParam("idTask") Long idTask,@RequestParam("description") String description,@RequestParam("filepath") String filepath){

    //TaskDocumentEntity document = new TaskDocumentEntity();
    taskDocumentRepository.insertDocumentByTaskId(idTask,descriere,filepath);
}

When I run my test, I get this error: Caused by: org.hibernate.hql.ast.QuerySyntaxException: expecting OPEN, found 'c' near line 1, column 32 [insert into TaskDocumentEntity c (c.idTask, c.descriere, c.filepath) values (:id,:descriere,:filepath)] I tried to remove the alias c, and still doesn`t work.

Spring data provides out of the box save method used for insertion to database - no need to use @Query. Take a look at core concepts of springData (http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.core-concepts)

thus in your controller just create object TaskDocumentEntity and pass it to repository

@RequestMapping(value = "/services/tasks/addDocument", method = RequestMethod.POST)
@ResponseBody
public void set(@RequestParam("idTask") Long idTask,@RequestParam("description") String description,@RequestParam("filepath") String filepath){

// assign parameters to taskDocumentEntity by constructor args or setters
        TaskDocumentEntity document = new TaskDocumentEntity(idTask,descriere,filepath);
        taskDocumentRepository.save(document);
    }
