只需在填充时将最后一个参数从表单设置为操作，为什么？

标签： java forms struts2 setter populate

这是我在jsp中的表单。当我提交它时，在服务器日志中我可以看到所有参数及其值，但是当我执行对象的println时，只是设置了最后一个（按字母顺序）。

<s:form action="contactos-modificar" method="POST" name="editarContacto">
    <s:hidden name="contactoModif.id" value="%{contactoEditar.id}"/>
    <div id="top">
        <label for="contactoModif.nombre">Nombre</label><br/>
        <s:textfield cssClass="large" name="contactoModif.nombre" value="%{contactoEditar.nombre}" />
    </div>

    <div id="izq">
        <label for="contactoModif.lugarNac">Lugar de nacimiento</label><br/>
        <s:textfield cssClass="large" name="contactoModif.lugarNac" value="%{contactoEditar.lugarNac}" />
        <br/>
        <label for="contactoModif.empresa">Empresa</label><br/>
        <s:textfield cssClass="large" name="contactoModif.empresa" value="%{contactoEditar.empresa}"/>
        <br/>
        <label for="localizacion">Localización</label><br/>
        <s:textfield cssClass="large" name="contactoModif.localizacion" value="%{contactoEditar.localizacion}"/>
    </div>

    <div id="dcha">
        <label for="contactoModif.fechaNac">Fecha de nacimiento</label><br/>
        <s:textfield cssClass="large" name="contactoModif.fechaNac" value="%{contactoEditar.fechaNac}"/>
        </br>
        <label for="contactoModif.puesto">Puesto</label><br/>
        <s:textfield cssClass="large" name="contactoModif.puesto" value="%{contactoEditar.puesto}"/>
        <br/>
        <label for="contactoModif.direccion">Dirección</label><br/>
        <s:textarea cssClass="direccion" name="contactoModif.direccion"><s:property value="contactoEditar.direccion"/></s:textarea>
    </div>

    <div id="bot">
        <label for="contactoModif.notas">Notas</label><br/>
        <s:textarea cssClass="notas" name="contactoModif.notas"><s:property value="contactoEditar.notas"/></s:textarea>
        <br/>

        <s:submit cssClass="submit" value="Guardar cambios"/>
    </div>

Just＆＃34; contactoModif.puesto＆＃34;被设置为对象。其他的都是空的。

这是我的目标：

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
}

}

我试过＆＃34; contactoModif.nombre，＆＃34; contactoModif.empresa＆＃34;和＆＃34; contactoModif.lugarNac＆＃34;同样的事情发生了，只是＆＃34; contactoModif.nombre＆＃34;设置了（另一次是按字母顺序排列的最后一个，因为它是由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，它让我发疯，对我来说解决这个问题非常重要，如果我不能使用struts2方式，我想我会使用html表单和getServletRequest（）。

1 个答案:

答案 0 :(得分：1)

嗯，我不知道为什么这样做不起作用，但我尝试了这个：

<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;
}

现在它可以工作，我收到表单的所有字段，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”方法来获取表单中的值），其余的代码是相同的。

PS：谢谢MohanaRao SV，编辑我的代码以显示颜色并使其更清晰。
