标签： java spring maven spring-mvc glassfish

我想在Spring MVC框架中的NetBeans中编写一个简单的Web Store。但是当我在Glassfish上部署我的程序时，发生了以下错误：

Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.karans.webstore.models.Daoimp.UserDAOimp] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}. Please see server.log for more details`.

我的pom.xml是：

我的web.xml是：

MVC-调度员的servlet：

<?xml version="1.0" encoding="UTF-8"?>

 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd

    </property>
    <property name="suffix">

    </property>
</bean>

弹簧Datasource.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans

</bean>
<bean id="productcontroller" class="com.karans.webstore.controllers.productController">

    <property name="ProductDaoimp" ref="ProductDAOimp"></property>
</bean>

UserDAOimp：

package com.karans.webstore.models.Daoimp;

import com.karans.webstore.models.Dao.UserDAO;
import com.karans.webstore.models.User;
import org.springframework.beans.factory.annotation.Autowired;



import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;

public class UserDAOimp  implements UserDAO{
@Autowired


 JdbcTemplate template;
@Override
public User GetUsertByUsername(String username, String password) {
    User user=null;
    String sql = "select * from user where username=? AND password=?";
  user=(User) template.queryForObject(sql, new Object[]{username ,password},new BeanPropertyRowMapper(User.class));
    return  user;
}

}

其他课程都是这样的。 UserDAO的：

package com.karans.webstore.models.Dao;

import com.karans.webstore.models.User;


public interface UserDAO {
public User GetUsertByUsername(String username,String password); 


}

用户：

package com.karans.webstore.models;
public class User {



private int iduser;;
   private String username;
   private String password;

public void setIduser(int iduser) {
    this.iduser = iduser;
}

public int getIduser() {
    return iduser;
}

public void setPassword(String password) {
    this.password = password;
}

public String getPassword() {
    return password;
}

public void setUsername(String username) {
    this.username = username;
}

public String getUsername() {
    return username;
}


}

UserController中：

package com.karans.webstore.controllers;
import com.karans.webstore.models.Daoimp.UserDAOimp;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class userController {
@Autowired
UserDAOimp userdaoimp;
@RequestMapping(value="/login", method = RequestMethod.GET )
public String login(){


    return "login";
}

@RequestMapping( value="/loginfailed", method = RequestMethod.GET)
public String loginError(Model model){
    model.addAttribute("error", "true");
    return "login";
}

@RequestMapping( value = "/logout", method = RequestMethod.GET)
public String logout(Model model){
    return "login";
}   
}

等等。 如何解决问题？

将上下文侦听器添加到web.xml以便弹出加载contextConfigLocation：

 <listener> 
    <listener-class>org.springframework.web.context.ContextLoade‌​rListener</listener-‌​class> 
 </listener>

您也可以尝试更改web.xml文件并删除web.xml的context-param部分，并将Spring-Datasource.xml设置为init-param到dispatcher servlet，如下所示：

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/Spring-Datasource.xml</param-value>
        </init-param>
</servlet>
