SpringMVC Junit4测试 "No ServletContext set"

讲真搞了一整天,虽然知道引发错误的是什么,但不能不使用它.

如果不进行测试(没有测试用例)则可以正常运行,由此可推出 Junit 没有生成 ServletContext

MyTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:springmvc-servlet.xml"  })
public class MyTest {

    @Resource
    TestService ts;
    @Test
    public void testSelect() {
        System.out.println("■■■■T■■■E■■■S■■■T■■■C■■■O■■N■■■S■■■O■■■L■■■E■■■■");
        System.out.println();
        System.out.println(ts.test());
        System.out.println();
        System.out.println("■■■■T■■■E■■■S■■■T■■■E■■■N■■D■■■I■■■N■■■G■■■!■■■■");
    }
}

Service实现类,接口就不贴了

@Service("testService")
public class TestServiceImpl implements TestService {

    @Override
    public String test() {
        return "cow cow";
    }

}

如果Config类没有@EnableWebMvc是正常运行的,也就是说
@EnableWebMvc 与 src/test/java 目录中的类有冲突,没有测试类能编译通过能在Tomcat运行,有测试类则不能用@EnableWebMvc 原因技术有限无法明白
这种情况隐约感觉跟配置或注解有关,拜托了各位

结贴了 真是技术有限无法实现 , 若真如此贴所示 Junit无法启动 web容器那也就说的通了,**无法启动也就 no servletContext**
参考 junit能否启动web项目设置的web listener?

额 柳暗花明又一村 ,
刚准备关闭问题 就找到了解决方案

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = { "classpath:applicationContext.xml","classpath:springmvc-servlet.xml" })
public class MybatisTest {
    //Test methods
}

一开始测试方向就错了 应该是测试 web context 所以需要使用注解

@WebAppConfiguration("src/main/resources") : 注解在类上,用来声明加载的ApplicationContex 是一个WebApplicationContext ,它的属性指定的是Web资源的位置,默认为 src/main/webapp ,自定义修改为 resource
这下能混合测试了。

关于springmvc junit中MockMVC测试controller 报空指针错误
controller中通过@RequestMapping拼接http访问url,请求方式是post, @ResponseBody注解的方法中传入两个参数,第一个用于url路径拼接,使用@PathVariable注解标识,第二个参数是一个自定义request对象,其中包含两个Integer字段以及一个 自定义类对象,类对象中包含3个String字段,再junit Test中定义一个MockMVC对象,调用Perform方法, post(url)并将参数通过.param传递,传递类对象时,通过变量名.字段传入,运行时报错空指针异常 如图![图片说明](https://img-ask.csdn.net/upload/201804/05/1522938220_69481.jpg) debug时进入了jar包中的.class文件,怀疑是不是注解使用不正确,哪位大佬可以帮忙解答一下,非常感谢!

Spring相关包引用 ![图片说明](https://img-ask.csdn.net/upload/201910/31/1572536093_691501.png) 本人在网上查询了很多方法,都说使用<mvc: resources .../>这个映射需要在其前面加上<mvc: annotation-driven />。但是我的项目里一开始配置springmvc的时候就已经有annotation-driven这个注解了,仍然无法访问静态资源。很是纳闷。然而使用<mvc: default-servlet-handler />这个注解就可以访问静态资源。再次发出问题,主要是想解决为什么annotation-driven这个注解不起作用,希望有过类似经验或者知道的朋友指导一下,甚是感激。小白,暂时没有币,还望不介意。

Springmvc在线程池中无法使用Service
问题:我在项目中使用线程池新建了线程列队,controller请求后把耗时任务交给列队处理, 列队中需要service注入,但是在Test中测,子线程无法使用service的方法,代码如下: TaskQueueHandler.java ``` public interface TaskQueueHandler { String getTaskName(); int doInvoke(); } ``` TaskSerialQueueService.java ... ``` @PostConstruct public void init(){ serviceThreadStatus=service.submit(new Thread(new Runnable() { @Override public void run() { while (running){ try{ TaskQueueHandler taskQueueHandler= tasks.take(); if(taskQueueHandler!=null){ try{ taskQueueHandler.doInvoke(); }catch (Exception e){ log.error(taskQueueHandler.getTaskName()+" doInvoke Error!",e.getCause()); } } }catch (InterruptedException e){ running=false; } } } })); } /** * 往列队中添加新任务 * @param taskQueueHandler * @return */ public synchronized boolean addTask(TaskQueueHandler taskQueueHandler){ if(!checkServiceIsActive()){ activeService(); } boolean success= tasks.offer(taskQueueHandler); if(!success){ log.warn(taskQueueHandler.getTaskName()+"任务列队添加失败!"); } return success; } ``` ... WxPayNotifyTask.java ``` public class WxPayNotifyTask implements TaskQueueHandler{ private String orderNo; public WxPayNotifyTask(String mOrderNo){ this.orderNo=mOrderNo; } @Override public String getTaskName() { return WxPayNotifyTask.class.getSimpleName(); } private OrderService orderService; @Override public int doInvoke() { System.out.println("orderNo="+orderNo); orderService= (OrderService)SpringUtils.getBean("orderService"); try{ OrderBean orderBean=orderService.queryByOrderNo(orderNo); System.out.println(orderBean.toString()); }catch (Exception e){ e.printStackTrace(); } return 0; } } ``` 测试代码中调用 ``` @Autowired private TaskSerialQueueService taskQueueService; taskQueueService.addTask(new WxPayNotifyTask("379991638464417792")); ``` 测试发现报错信息如下 ``` org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: interrupt at org.springframework.jdbc.datasource.DataSourceTransactionManager.doBegin(DataSourceTransactionManager.java:289) at org.springframework.transaction.support.AbstractPlatformTransactionManager.getTransaction(AbstractPlatformTransactionManager.java:377) at org.springframework.transaction.interceptor.TransactionAspectSupport.createTransactionIfNecessary(TransactionAspectSupport.java:461) at org.springframework.transaction.interceptor.TransactionAspectSupport.invokeWithinTransaction(TransactionAspectSupport.java:277) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:96) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.interceptor.ExposeInvocationInterceptor.invoke(ExposeInvocationInterceptor.java:92) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.framework.CglibAopProxy$DynamicAdvisedInterceptor.intercept(CglibAopProxy.java:673) at com.superior.chalk.service.order.OrderServiceImpl$$EnhancerBySpringCGLIB$$d45a5b10.queryByOrderNo(<generated>) at com.superior.chalk.task.WxPayNotifyTask.doInvoke(WxPayNotifyTask.java:27) at com.superior.chalk.task.queue.TaskSerialQueueService$1.run(TaskSerialQueueService.java:35) at java.lang.Thread.run(Thread.java:745) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.sql.SQLException: interrupt ``` 最后发现如直接在test中使用 new WxPayNotifyTask("379991638464417792").invoke()是可以使用service的,但是在子线程中能获取到service但调用service的方法就报错。 先谢谢各位大佬帮忙分析分析!

junit测试可以加载web.xml中的servlet么?如何加载?
【问题背景】: 1、spring+springMVC+hibernate项目。 2、编写测试用例暂未用到其他测试框架。 3、基于controller写的测试用例。 4、已在base测试类中spring运行器并加载spring配置文件,运行测试用例可获取到对应bean。 ``` @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"classpath:aop/applicationContext.xml"}) ``` 【问题】:在用例执行过程中,调用dao的方法中有调用外部配置在web.xml中servlet解析xml,但是此处未能加载到该servlet,导致用例执行失败。报错 ``` 无法加载spring上下文 ``` 已测试将该servlet配置到spring的bean中,但执行依旧不行。 【求助】 请问junit测试过程中是否可以通过加载web.xml来加载启动其中的servlet呢?如果可以怎么配置使用呢?

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

漫话:什么是平衡(AVL)树?这应该是把AVL树讲的最好的文章了
这篇文章通过对话的形式,由浅入深带你读懂 AVL 树,看完让你保证理解 AVL 树的各种操作,如果觉得不错,别吝啬你的赞哦。 1、若它的左子树不为空,则左子树上所有的节点值都小于它的根节点值。 2、若它的右子树不为空,则右子树上所有的节点值均大于它的根节点值。 3、它的左右子树也分别可以充当为二叉查找树。 例如: 例如,我现在想要查找数值为14的节点。由于二叉查找树的特性,我们可...
