java - Retrieve an annotated field from a class in the view -

in current spring project, atributes entity classes have annotations indicate type of form control should used data input, this:

@column(name = "login", unique=true) @order(value=1) @input(name="login") private string login;  @column(name = "senha") @order(value=2) @input(type="password", name="senha") private string senha;  @column(name="nome") @order(value=3) @input(name="nome") private string nome;  @column(name="sobrenome") @order(value=4) @input(name="sobrenome") private string sobrenome;  @column(name="email") @order(value=5) @input(name="email") private string email; 

and have custom tags should read atributes of annotations , add page correct tag, that:

public class inputtag extends tagsupport {     /**      *       */     private static final long serialversionuid = 1l;      public void dotag() throws ioexception, nosuchfieldexception, securityexception {         jspwriter out = pagecontext.getout();         string name = this.getname();         string type = this.gettype();         string pattern = this.getpattern();          if(type == null) {             if(pattern == "") {                 out.println("<form:input path=\""+name+"\" class=\"form-control\"/>");             } else {                 out.println("<form:input path=\""+name+"\" class=\"form-control valida\" pattern=\""+pattern+"\"/>");             }         } else {             if(pattern == "") {                 out.println("<form:input path=\""+name+"\" type=\""+type+"\" class=\"form-control\"/>");             } else {                 out.println("<form:input path=\""+name+"\" type=\""+type+"\" class=\"form-control valida\" pattern=\""+pattern+"\"/>");             }         }     }     ... } 

the getter methods tag class have format:

private string getname() throws nosuchfieldexception, securityexception {     field field = null;     annotation annotation = field.getannotation(input.class);     input inputannotation = (input) annotation;     string name = inputannotation.name();     return name; } 

what need right it's way of store in variable field field want add page. know method if inside entity class (something getclass().getfield("<nome>")), how access information tag class?

the view mapped in controller way:

@requestmapping(value="cadastra") @preauthorize("haspermission(#user, 'cadastra_'+#this.this.name)") public string cadastra(model model) throws instantiationexception, illegalaccessexception {     model.addattribute("command", this.entity.newinstance());     return "private/cadastrar"; } 

and jsp code in moment it's (just basic structure):

<c:url value="/${entity}/cadastra" var="cadastra"/> <form:form method="post" action="${cadastra}" class="form" enctype="multipart/form-data">      <button type="submit" class="btn btn-lg btn-primary">cadastrar</button>  </form:form> 

anyone knows way accomplish this?
