小编dar*_*one的帖子

我正在进行下一个测试:

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/META-INF/spring/applicationContext.xml" })
public class FloorServiceTest {

    @Autowired
    private FloorService floorService;

    @Test
    public void testFloorService() {

        floorService.findById((long)1);

    }
}

用文件applicationContext.xml夹下的文件/APP/src/main/resources/META-INF/spring/

但似乎没有正确地自动装配bean:

  org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.confloorapp.services.FloorServiceTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.confloorapp.services.FloorService com.confloorapp.services.FloorServiceTest.floorService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.confloorapp.services.FloorService] found for dependency: expected at least …

我想使用 PuTTY 程序连接我的串口，但这是不可能的，当我点击“打开”时什么也没有发生。在 Mac OS X 和 VirtualBox 的 Windows 7 下，我只听到“哔哔哔”的声音

当组合框值发生变化时，我想获得组合框的旧值。

我尝试过类似的事情：

Private Sub ComboBox1_Change()
        Application.EnableEvents = False
        newVal = ComboBox1.Value
        Application.Undo
        oldVal = ComboBox1.Valu
End Sub

或者

Private Sub ComboBox1_Change()
        Application.EnableEvents = False
        newVal = ComboBox1.Value
        ComboBox1.Undo
        oldVal = ComboBox1.Valu
End Sub

但它似乎不起作用......

谢谢

我试图从数据库中的对象做一个简单的加载,但我得到错误"无法初始化代理 - 没有会话",任何想法？谢谢

org.hibernate.LazyInitializationException: could not initialize proxy - no Session

public class UserFormValidator implements Validator {

    return UserForm.class.equals(clazz);

public UserDAO getUserDAO() {
    return userDAO;
}

public void setUserDAO(UserDAO userDAO) {
    this.userDAO = userDAO;
}

@Override

}

如果我使用@Autowired,这个servlet中的服务为null,它使用context.getBean(); 此外,使用/ floorOperationWS /的映射没有完成,我必须在web.xml中定义映射.

package com.confloorapp.services.endpoint;

import java.io.IOException;
import java.util.Date;
import java.util.Enumeration;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;



@WebServlet(value = "/floorOperationWS/")
public class UpdateFloorEventServlet extends HttpServlet {


    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        ApplicationContext context = WebApplicationContextUtils.getWebApplicationContext(getServletContext());


            FloorService floorService = (DoorService)context.getBean("floorService");

}



}

这里是applicationContext.xml
