关于spring整合struts的出现问题

我applicationContext中的配置和action里面的内容如下：

<bean id="productService" class="com.store.serviceImpl.ProductServiceImpl">
    <property name="pdao" ref="productDao"/>
</bean
 <bean name="allproductAction" class="com.store.action.AllProductAction" scope="prototype">
    <property name="pservice" ref="productService"/>
</bean>
public class AllProductAction extends ActionSupport{
private ProductService pservice;
private List product;
private int productID;
public ProductService getPservice() {
return pservice;
}
public void setPservice(ProductService pservice)
{
this.pservice = pservice;
}
 public List<Product> getCommodity() {
    return product;
}

public void setCommodity(List<Product> product) {
    this.product = product;
}
public int getproductID() {
    return productID;
}

public void setproductID(int productID) {
    this.productID = productID;
}
public String execute() throws Exception {
    product = pservice.findAll();
    return SUCCESS;
}
}

为什么我运行之后会提示一下错误：

严重: Could not open template
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'allproductAction' defined in ServletContext resource [/WEB-INF/applicationContext-actions.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'pservice' of bean class [com.store.action.AllProductAction]: Bean property 'pservice' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

求大神指教啊！
