我的UserDao是接口,我只贴实现
UserDaoImp.java

import com.zhaoshg.test.model.U
* @author kaiming..cn
public class UserDaoImp extends SqlMapClientDaoSupport implements UserDao {
public User getUserByUsername(String username) {
return (User) getSqlMapClientTemplate().queryForObject("getUserByUsername", username);
UserServiceImp.java,也只贴实现
package com.zhaoshg.test.
import mons.lang.StringU
import com.zhaoshg.test.dao.UserD
import com.zhaoshg.test.model.U
public class UserServiceImp implements UserService {
private UserDao userD
* (non-Javadoc)
* com.zhaoshg.test.service.UserService#getUserByUsername(java.lang.String)
public User getUserByUsername(String username) {
if (username == null || StringUtils.isBlank(username))
return userDao.getUserByUsername(username);
public UserDao getUserDao() {
return userD
public void setUserDao(UserDao userDao) {
this.userDao = userD
在看看我的action
UserAjaxAction.java

return userS
public void setUserService(UserService userService) {
this.userService = userS
这里代码差不多了.
我启动是没错的.但是访问这个action的时候/ajax/userNameValidate就开始报上面的错了.
希望各位帮忙
问题补充：songfantasy 写道还有我感觉你的配置文件放的很乱。不清晰。最好就是统一管理配置文件。
songfantasy 写道发现个问题，web.xml很有问题。
#&&&& &context-param&&
#&&&&&&&& ¶m-name&contextConfigLocation&/param-name&&
#&&&&&&&& ¶m-value&&
#&&&&&&&& classpath:/spring/applicationContext.xml&
#&&&&&&&& classpath:/spring/applicationContext-resources.xml&
#&&&&&&&& &/param-value&&
#&&&& &/context-param&&
#&&&& &listener&&
#&&&&&&&& &listener-class&org.springframework.web.context.ContextLoaderListener&/listener-class&&
#&&&& &/listener&
把这段放入web.xml最上面，不要把struts2的配置放在最上面。struts2已经由spring管理，不能放在Spring前面。
这个也试过了,不行...
问题补充：songfantasy 写道在src下加上log4j吧。
有log4j的配置文件
问题补充：songfantasy 写道实在不行，在Action中 ajax/userNameValidate而你配置文件中& 却是validateUserName
在Action中加上个断点，看是否进入了Action。单步调试。跟踪。
进不去action.我看了下,错误应该是包的依赖关系出了问题,或者包有冲突,我打算用直接在lib下面加jar包的方法,看看是哪些包有问题.
