spring单元测试dao层

除了要junit的包4.0以上的，还要spring-test的包

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>4.2.4.RELEASE</version>
    <scope>test</scope>
</dependency>

然后在测试类上使用RunWith和ContextConfiguration注解，还有方法上要加Test注解。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring/applicationContext-*.xml"})
public class TestSearchItemMapper {

    @Autowired
    private SearchItemMapper searchItemMapper;

    @Test
    public void testGetItemList() {
        List<SearchItem> searchItemList = searchItemMapper.getItemList();

        for (SearchItem s : searchItemList) {
            System.out.println(s);
        }
    }

}
