Answer 1

[com.rj0812.service.UserService] for property 'newscolService'

Answer 2

无法实例化这个'UserAddAction' 

Answer 3

我加入service后出现的这个情况，这个我的<bean id="userService" class="com.rj0812.service.imp.UserServiceImp">
<property name="userDao">
<ref bean="userDao"/>
</property>
</bean>
还有<bean id="userDao" class="com.rj0812.dao.imp.UserDaoImp">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>，这个是action中private UserService userService;
private static final long serialVersionUID = -4134661411623487672L;
private TUser user = new TUser();
public void setNewscolService(UserService userService) {
this.userService = userService;
}
public String execute(){
System.out.println(user.getFUserid());
System.out.println(user.getFUserpassword());
System.out.println(user.getFUsertype());
return SUCCESS;
}
public TUser getModel() {
// TODO Auto-generated method stub
return user;
}我还没有使用service呢，为什么就有错误了呢？

Answer 4

spring配置文件里的UserAction里的UserService属性不匹配吧？？
把 UserAction 源码和 spring配置文件贴出来看看。。

Answer 5

错误的含义是 不能把 com.rj0812.service.NewscolService 转换成
com.rj0812.service.UserService

Answer 6

public class UserAddAction extends ActionSupport implements ModelDriven<TUser>{
private UserService userService;
private static final long serialVersionUID = -4134661411623487672L;
private TUser user = new TUser();
public void setNewscolService(UserService userService) {
this.userService = userService;
}
public String execute(){
System.out.println(user.getFUserid());
System.out.println(user.getFUserpassword());
System.out.println(user.getFUsertype());
return SUCCESS;
}

Answer 7

private UserService userService
是否是把UserService 的包导入错了？？

Answer 8

import com.rj0812.service.UserService;package com.rj0812.service;import com.rj0812.bean.TUser;public interface UserService {
/*添加用户*/
public boolean doAddUser(TUser user);
}
就是这个包啊

Answer 9

package com.rj0812.action.user;import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.rj0812.bean.TUser;
import com.rj0812.dao.UserDao;
import com.rj0812.service.UserService;

Answer 10

lz全局查找 com.rj0812.service.NewscolService 
看看你是不是在什么地方配置了这个。。

Answer 11

请问你的qq号多少我加你qq行不？

Answer 12

我怀疑是你这里有问题：
public void setNewscolService(UserService userService) {
   this.userService = userService;
}
如果你把Service的实例化工作交给Spring的话，setter方法的名字应该写成：setUserService（）；因为Spring是根据setter 后面的名称为属性赋值的，写成别的Spring就找不到了！试试吧！
