这是我在jsp中的表格。当我提交它时，可以在服务器日志中看到所有参数及其值，但是当我对对象执行println时，仅设置了最后一个（按字母顺序）。

只是将“ contactoModif.puesto”设置为该对象。其他的是空的。
这是我的对象：
public class ContactoPerfil {
private static final long serialVersionUID = 1L;
private int id=0;
private String nombre="";
private String fechaNac="";
private String lugarNac="";
private String empresa="";
private String puesto="";
private String direccion="";
private String localizacion="";
private String notas="";
public int getId(){
return id;
}
public String getNombre(){
return nombre;
}
public String getFechaNac(){
return fechaNac;
}
public String getLugarNac(){
return lugarNac;
}
public String getEmpresa(){
return empresa;
}
public String getPuesto(){
return puesto;
}
public String getDireccion(){
return direccion;
}
public String getLocalizacion(){
return localizacion;
}
public String getNotas(){
return notas;
}
public void setId(int id){
this.id = id;
}
public void setNombre(String nombre){
this.nombre = nombre;
}
public void setFechaNac(String fechaNac){
this.fechaNac = fechaNac;
}
public void setLugarNac(String lugarNac){
this.lugarNac = lugarNac;
}
public void setEmpresa(String empresa){
this.empresa = empresa;
}
public void setPuesto(String puesto){
this.puesto = puesto;
}
public void setDireccion(String direccion){
this.direccion = direccion;
}
public void setLocalizacion(String localizacion){
this.localizacion = localizacion;
}
public void setNotas(String notas){
this.notas = notas;
}
@Override
public String toString(){
//code
}
}
我尝试使用“ contactoModif.nombre”，“ contactoModif.empresa”和“ contactoModif.lugarNac”进行了相同的操作，只是设置了“ contactoModif.nombre”（另一时间是按字母顺序排列的，因为这是由struts2转换的最后一个）。
在行动中：
public class ContactosAction extends ActionSupport implements SessionAware,ServletRequestAware{
private ContactoPerfil contactoModif;
@Action(value="contactos-modificar",
results={
@Result(name="success", type="stream", params={"contentType","text/html","inputName","inputStream"}),
@Result(name="error", type="stream", params={"contentType","text/html","inputName","inputStream"})}
)
public String modificarContacto() throws Exception{
//code
}
public void setContactoModif(ContactoPerfil c){
this.contactoModif=c;
}
}
Struts版本：2.3.4
我需要帮助，这使我发疯，对于我来说，解决这个问题非常重要，如果我无法使用struts2的方式实现这一功能，我想我将使用html表单和getServletRequest（）。
最佳答案
好吧，我不知道为什么这种方式不起作用，但是我尝试了以下方法：
<label for="contactoModif.nombre">Nombre</label><br/>
<input type="text" class="large" name="contactoModif.nombre" value="<s:property value="contactoEditar.nombre"/>"/>
在行动中：
public ContactoPerfil getContactoModif(){
return contactoModif;
}
现在工作了，我收到了表单的所有字段，并且所有字段都存储在对象中。
我只是更改了字段并添加了“ get”方法（我认为只需要“ set”方法即可从表单中获取值），其余的代码是相同的。
PS：谢谢MohanaRao SV，感谢他们编辑我的代码以显示颜色并使其更加清晰。
