1.引入相关依赖
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
<scope>test</scope>
</dependency>
2.新建java单元测试文件加上spring配置文件的注解
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration({"classpath*:spring/*.xml"}) public class MapperTest { @Autowired private ProductTypeMapper mapper; @Test public void testProductType(){ ProductTypeExample example = new ProductTypeExample(); List<ProductType> list = mapper.selectByExample(example); System.out.println(list); } }
