Question

i CRUD App mache mit Hibernate Spring MVC und JS .. und jetzt hier arbeite ich .. eine Zeile in der DB in lösche meinen Code meine js

deleteRow : function() { 
    $("input:checkbox:checked").each(bindContext(function(index, item) { 
     var str = $(item).attr("id"); 
     str = str.substring(str.indexOf("_") + 1); 

     $.ajax({ 
      url : '/Spring3HibernateApp1/delete', 
      type : 'POST', 
      data : { 
       "id" : str, 
      } 
     }); 
     this.data.splice(str, 1); 
     this.deleteTable(); 
     this.display(); 
    }, this)); 
}, 

mein Controller

@RequestMapping(value = "/delete") 
public @ResponseBody void doPostDelete(@RequestBody String id,Employee employee){ 
    int idInt = Integer.parseInt(id); 
    employee.setEmpId(idInt-1); 
    employeeService.deleteEmployee(employee); 
} 

es tritt an die Steuerung und sagt jquery.min.js: 4 POST http://localhost:8080/Spring3HibernateApp1/delete 500 (Internal Server Error)

irgendwelche Vorschläge ??

Answer 1

HTTP 500 Fehler Mittelwert, dem Controller schlechter

Ihren Controller mit diesem

@RequestMapping(value = "/delete/{id}" method = RequestMethod.POST, produces = "application/json") 
    @ResponseBody 
    public void doPostDelete(@RequestBody Employee employee, @PathVariable("id") String id) { 
     int idInt = Integer.parseInt(id); 
     employee.setEmpId(idInt - 1); 
     employeeService.deleteEmployee(employee); 
    } 

und Ihren JavaScript-Code wie dieser

deleteRow : function() { 
    $("input:checkbox:checked").each(bindContext(function(index, item) { 
     var str = $(item).attr("id"); 
     str = str.substring(str.indexOf("_") + 1); 

     $.ajax({ 
      url : '/Spring3HibernateApp1/delete/' + id, // id is your patvariable 
      type : 'POST', 
      data : str // str must equal to employee json object 
     }); 
     this.data.splice(str, 1); 
     this.deleteTable(); 
     this.display(); 
    }, this)); 
},
