java - AutoConfigureMybatis注解是什么意思？
问题描述
该项目正在使用Spring Boot，其中一些pom.xml如下所示
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.2.RELEASE</version>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.2.0</version>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter-test</artifactId>
<version>1.3.2</version>
<scope>test</scope>
</dependency>
我的问题与此类似。我检查了它的描述，如果想要集成测试，Mybatis建议添加@AutoConfigureMybatis的成员。但是，我只想测试控制器。在另一个问题中，它还讨论了控制器测试以外的其他内容。
我的一个测试可以成功通过，但其他的会抛出异常
Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required
如果我删除@AutoConfigureMybatis注释并且@AutoWired ApplicationContext.The pass 的测试将在以下异常中失败。
java.lang.IllegalStateException: Failed to load ApplicationContext
堆栈跟踪信息显示了它尝试使用真实数据库访问信息的测试。但是，在同一类中获取请求测试已通过。不知道如何AutoConfigureMybatis工作，以及我的问题的原因是什么。

部分源代码。
在 TemplateControllerTest.java 中
@RunWith(SpringRunner.class)
@AutoConfigureMybatis
@WebMvcTest(TemplateController.class)
public class TemplateControllerTest {
@Autowired
private MockMvc mvc;
@Autowired
private ApplicationContext applicationContext;
@MockBean
private TemplateService templateService;
@MockBean
private DataPointService dataPointService;
private Template mockTemplate;
@Test
public void delTemplateTest() throws Exception {
mockTemplate = new Template();
mockTemplate.setTemplateId(1);
mockTemplate.setName("Test");
mockTemplate.setUserId(2);
given(templateService.queryTemplateById(1)).willReturn(mockTemplate);
given(templateService.delTemplate(1)).willReturn(1);
RequestBuilder requestBuilder = MockMvcRequestBuilders.delete("/template/destroy/1");
mvc.perform(requestBuilder).andDo(print())
.andExpect(status().isOk()).andExpect(jsonPath("$.code").value("200"));
}
在 TemplateController.java 中
@Transactional
@DeleteMapping("/destroy/{templateId}")
public BaseResponse destroy(@PathVariable Integer templateId) {
// I put a breakpoint here,but it did't get in
解决方案
问题是Transactional您的控制器方法上有注释（很可能您提到的 get 方法不是这种情况）。
您模拟了对服务的调用，但事务管理仍处于打开状态并应用于控制器，因此 spring 在调用方法之前尝试创建事务。
通常服务方法被标记为Transactional，如果你这样做，你就不会遇到这个问题。
