[英]Testing non-blocking REST services with Spring MVC
我有一個 Spring MVC 應用程序。 我想測試這個控制器:
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("classpath:backoffice-servlet.xml")
public class TimeControllerTests {
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
@Test
public void should_OK() throws Exception {
mockMvc.perform(get("/time/2")
.contentType(APPLICATION_JSON))
.andExpect(status().isOk());
}
}
這是我的backoffice-servlet.xml
:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.bonanza.*" />
<mvc:annotation-driven />
</beans>
但是當我啟動應用程序時。 我收到此錯誤:
Error creating bean with name 'documentController': Unsatisfied dependency expressed through field 'documentService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'documentService': Unsatisfied dependency expressed through field 'documentRepo'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.bonanza.repositories.documents.DocumentRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
回購:
@Repository
public interface DocumentRepository extends JpaRepository<Document, Long> {
...
}
由於存儲庫是 Spring Data 存儲庫,因此應在 XML 配置文件中添加適當的初始化:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation="
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">
<context:component-scan base-package="com.bonanza.*" />
<mvc:annotation-driven />
<jpa:repositories base-package="<<REPOSITORY_PACKAGE_NAME>>"/>
</beans>
這是Spring Data 參考指南的鏈接。
如果不使用 Spring Boot,則可能還需要添加基礎 JPA 類 - dataSource、transactionManager、entityManagerFactory 並引用實體包。 配置取決於測試環境:使用真實/內存數據庫或其他選項。 對於事務管理,XML 配置中還需要<tx:annotation-driven />
。 這是Spring 參考指南中相應章節的鏈接。
這里可以找到實體管理器工廠/事務管理器 XML 配置的示例。
從這里采取的另一個例子:
<?xml version="1.0" encoding="UTF-8"?>
