Question

Sto cercando di inviare un oggetto JSON a un controller in primavera 3.

sto ottenendo il seguente errore:

mio controller :

@RequestMapping(value = MappingConstants.RULE_ASSIGNMENT, method = RequestMethod.POST) 
public String saveRuleAssignment(@RequestBody RuleAssignmentCO ruleAssignment) { 

    return MappingConstants.REDIRECT + MappingConstants.RULE_ASSIGNMENT; 
} 

mio jQuery javascript:

ruleAssignment = { 
    titleId: titleId, 
    typeId: typeId, 
    seriesId: seriesId 
      } 

    jQuery.ajax({ 
    url: 'ruleAssignment', 
    type: 'POST', 
    dataType: 'json', 
    data: ruleAssignment, 
     contentType: 'application/json', 
     success: function(result) { 
     console.log('here'); 
     } 
    }); 

Answer 1

jQuery non codifica oggetti JavaScript in JSON automaticamente, è necessario farlo manualmente con JSON.stringify():

jQuery.ajax({ 
    url: 'ruleAssignment', 
    type: 'POST', 
    dataType: 'json', 
    data: JSON.stringify(ruleAssignment), 
    contentType: 'application/json', 
    success: function(result) { 
     console.log('here'); 
    } 
}); 

Nota che alcuni browser non supportano JSON.stringify() come metodo built-in, in questo caso è necessario json2.js per la portabilità.
