ps1:我更改了原始变量名,因此可能存在一些不一致性。
PS 2:我读到:
TestContext框架不会对
测试实例被实例化。因此@Autowired的使用
构造函数对测试类没有影响
地址:
这与我的问题有关吗?您的上下文中似乎没有
entityManagerFactory
。添加如下内容:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="dataSource" p:persistenceXmlLocation="META-INF/persistence.xml" />
足够了,因为默认情况下回滚为true
从上的Spring参考:
在TestContext框架中,事务由TransactionalTestExecutionListener管理,默认情况下通过@TestExecutionListeners注释配置,即使您没有在测试类上显式声明@TestExecutionListeners
将您的“测试类”DeviceController测试放入包中,例如org.example.controller,它将位于/src/test/java中。在您的文件夹/src/test/resources中,它表示org.example.controller,并将DeviceController-context.xml放入其中
DeviceController测试-context.xml文件应如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<context:property-placeholder location="classpath:*application-default.properties, classpath*:{your application name}-local.properties" />
<bean class="{your class with you want use to @Autowired}[org.example.yService]" />
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class DeviceControllerTest {
private static final Log LOG = LogFactory.getLog(DeviceControllerTest .class);
@Autowired
private YService yService;
@Test
public void test() {
//some actions TODO
}
}
这种结构更“好”,因为您总是知道用于某些特定“测试”的上下文,并且不需要在“测试类”中设置测试类上下文的位置.请发布完整的堆栈跟踪。异常堆栈跟踪的重要部分被切断。@Ralph我添加了完整的堆栈跟踪。@kamaci:您没有
实体管理工厂
;我更新了答案
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class DeviceControllerTest {
private static final Log LOG = LogFactory.getLog(DeviceControllerTest .class);
@Autowired
private YService yService;
@Test
public void test() {
//some actions TODO
}
}
