Java Can';在Junit测试中使用Spring注入DAO
我试图在Junit测试中使用HSQL内存数据库。我有一个实体模型:Java Can';在Junit测试中使用Spring注入DAO,java,spring,hibernate,junit,dependency-injection,Java,Spring,Hibernate,Junit,Dependency Injection,我试图在Junit测试中使用HSQL内存数据库。我有一个实体模型: package com.project.model.db; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name="users") public class User {
package com.project.model.db;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="users")
public class User {
@Id
@GeneratedValue
private Integer id;
...
还有一把刀
package com.project.dao.impl;
...
@Repository
public class UserDaoImpl
...
我的测试上下文(在src/test/resources/test context.xml下)全文如下:

但是当我运行测试时,我得到一个注入的UserDaoImpl的空指针异常。我不知道这是为什么?您正在使用Mockito JUnitRunner来运行测试-您需要使用SpringJunitRunner(不确定确切的类名是什么)。我同意,您使用了错误的运行程序,因为Mockito运行程序不理解相同的注释,并且无法初始化Spring应用程序上下文。Mockito runner基本上可以理解
@Mock
和@InjectMock
注释,但不能使用springI进行集成测试。我创建了一个runner,它可以同时执行这两个功能。。。春天和莫基托。听起来不仅仅是我需要它。我不知道它的好处。你是否想做单元,集成,验收。。。但并非所有测试都在同一时间进行。除非您可以轻松地将模拟添加到现有的spring应用程序上下文中(这在Scala和cake模式中非常容易;p)
package com.project.dao.impl;

import com.project.model.db.User;

@RunWith(MockitoJUnitRunner.class)
@ContextConfiguration({ "classpath:/test-context.xml" })
