無法處理提交的外鍵

有3一個一對多的關係發展成一個實體PTA：無法處理提交的外鍵

@Entity 
@Table(name = "pta") 
public class Pta { 

    @Id() 
    @SequenceGenerator(name="s_pta", sequenceName="pta.s_pta", allocationSize=1) 
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="s_pta") 
    @Column(name="pta_code")  
    private Integer code; 

    @Column(name="pta_intitule") 
    private String lib; 

    @ManyToOne 
    @JoinColumn(name = "obj_code") 
    private Objectif objectif; 

    @ManyToOne 
    @JoinColumn(name = "struct_code") 
    private Structure structure; 

    @ManyToOne 
    @JoinColumn(name = "exer_code") 
    private Exer exercice; 

    public Pta() { 
     super(); 
    } 

    public Pta(Integer code) { 
     super(); 
     this.code = code; 
    } 

    // getters and setters 

} 

@Entity 
@Table(name = "objectif") 
public class Objectif { 

    @Id 
    @SequenceGenerator(name="s_objectif", sequenceName="pta.s_objectif", allocationSize=1) 
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="s_objectif") 
    @Column(name = "obj_code") 
    private int code; 

    @Column(name="obj_intitule") 
    private String lib; 

    @ManyToOne 
    @JoinColumn(name = "prog_code") 
    private Programme programme; 

    @ManyToOne 
    @JoinColumn(name = "nat_obj_code") 
    private NatureObjectif nature_objectif; 

    public Objectif() { 
     super(); 
    } 

    public Objectif(int code) { 
     super(); 
     this.code = code; 
    } 

    public Objectif(int code, String lib) { 
     super(); 
     this.code = code; 
     this.lib = lib; 
    } 

    // getters and setters 

} 

@Entity 
@Table(name = "structure") 
public class Structure { 

    @Id() 
    @Column(name="struct_code") 
    private String code; 

    @Column(name="struct_sigle") 
    private String sigle; 

    @Column(name="struct_lib") 
    private String lib; 

    public Structure() { 
     super(); 
    } 

    public Structure(String code) { 
     super(); 
     this.code = code; 
    } 

    // getters and setters 

} 

@Entity 
@Table(name = "exercice") 
public class Exer { 

    @Id() 
    @Column(name="exer_code") 
    private String exerCode; 

    @Column(name="exer_lib") 
    private String exerLibelle; 

    public Exer(){ 
     super(); 
    } 

    public Exer(String exer_code) { 
     super(); 
     this.exerCode = exer_code; 
    } 

    // getters and setters 

}

我想插入一條記錄到PTA。

控制器頁面的jsp：

modelView.addObject("exercices",exerDao.list()); 
modelView.addObject("structures",structureDao.list()); 
HashMap<String, String> criteres = new HashMap<String, String>(); 
criteres.put("nat_obj_code", "DdP"); 
modelView.addObject("docs_perf", objectifDao.lireParCritere(criteres)); 
criteres.clear(); 
criteres.put("nat_obj_code", "ODD"); 
modelView.addObject("odds", objectifDao.lireParCritere(criteres)); 
criteres.clear(); 
criteres.put("nat_obj_code", "PRO"); 
modelView.addObject("produits", objectifDao.lireParCritere(criteres)); 
modelView.addObject("action", request.getContextPath().concat("/elaboration/savePtaEtDetails")); 
modelView.addObject("pta_formulaire", new Pta()); 
return modelView;

在控制目標：

@RequestMapping(value = "/savePtaEtDetails", method = RequestMethod.POST) 
    public ModelAndView savePtaEtDetails(@ModelAttribute("pta_formulaire") Pta pta, @RequestParam String exercice, @RequestParam int objectif, 
             @RequestParam String structure) { 

     System.out.println("eeeeeeeeeeeeeeee"); 

     return new ModelAndView("redirect:/accueil"); 

    }

在運行時提交表單時，然後我得到了錯誤The request sent by the client was syntactically incorrect。那麼，什麼是錯的？

我發現它:)解決的辦法是不設置在「主」實體的構造函數的屬性：

public Exer(String exer_code) { 
     super(); 
    } 

public Structure(String code) { 
     super(); 
    } 

public Objectif(String code) { 
     super(); 
    }
