Spring与struts2不配合要如何整 呢？

Spring与struts2不配合要怎么整 呢？？
spring与hibernate 一起做测试的时侯是没问题的但是在整 合struts的时侯报这个空指针
java.lang.NullPointerException

我单独测Spring是没这个问题的 struts2-spring-plugin这个插件我也放到了lib目录里
Struts 和spring我都是用的注解配置的
这是Strutsr 配置
import java.util.Map;

import org.apache.struts2.convention.annotation.*;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;

import kq.service.LoginService;
import kqserviceimp.LoginServiceImp;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
@Component
@Namespace("/")
public class LoginAction extends ActionSupport{
  /**
* 
*/
private static final long serialVersionUID = 1L;
private String username;
  private String password;
  private LoginService loginservice=new LoginServiceImp();

public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Actions({
@Action(value="/login/log",results={
@Result(name="Success",location="WEB-INF/loginok.jsp"),
@Result(name="fail",location="WEB-INF/loginfail.jsp")
}),
@Action("/test/tx")
})
public String login(){
boolean t=loginservice.login(username, password);
if(t==true){
ActionContext actioncontext=ActionContext.getContext();
Map session=actioncontext.getSession();
session.put("username", username);
return "Success";
}
return "fail";
}
@Actions(
@Action(value="/ax/t",results={
@Result(name="null",location="/loginok.jsp")
}))
public String ok() {
return "null";
}
}
这是spring 的配置
import java.util.Properties;

import javax.annotation.Resource;
import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.Property;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean;

@Configuration
public class SpringConfig {
  private @Value("#{jdbcProperties.url}") String jdbcurl;
  private @Value("#{jdbcProperties.username}") String username;

  private @Value("#{jdbcProperties.password}") String password;
  @Bean(name="datasource")
  public DataSource dataSource(){
return new DriverManagerDataSource(jdbcurl,username,password);
  }
  @Bean(name="sessionFactory")
  public AnnotationSessionFactoryBean getsessionfactory(){
AnnotationSessionFactoryBean asFactoryBean=new 
AnnotationSessionFactoryBean();
asFactoryBean.setDataSource(dataSource());
Properties pro=new Properties();
pro.put("hibernate.dialect",org.hibernate.dialect.OracleDialect.class );
pro.put("hibernate.show_sql", true);
asFactoryBean.setHibernateProperties(pro);
asFactoryBean.setPackagesToScan("kq.bean");
return asFactoryBean;
  }
  @Bean(name="ht")
  public HibernateTemplate gethibernatetemplate(AnnotationSessionFactoryBean sessionfactory){
HibernateTemplate htp=new HibernateTemplate(sessionfactory.getObject());
return htp;
  }
}


[解决办法]
顶一下，看看debug调试，看那一行出现空指针之间不所需要的直输出一下看看传过来没。
[解决办法]
对用debug先看一下页面带过来值没有
