Mybatis批量插入返回成功的数目

Mybatis批量插入返回影响的行数

环境:

• postgresql 9.6.5
• spring 4.1
• mybatis3
• junit4
• log4j

ThesisMapper.xml:

    <insert id="insertList" parameterType="java.util.List">

        insert into public.thesis
        (name)
        values
        <foreach collection="list" item="t" index="index" separator=",">
            (
            #{t.name}
            )
        foreach>
    insert>

Mapper.java 借口:

public interface ThesisMapper {
    int insertList(List thesisList);
}

服务类:
ThesisService:

public int insertList(List thesisList) throws Exception {
    return thesisDao.insertList(thesisList);
}

测试父类:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring-mvc.xml", "classpath:spring-mybatis.xml" })
@WebAppConfiguration
public class BaseTest {

    @Autowired
    protected WebApplicationContext wac;

    @Test
    public void test() {}

}

测试类:

public class UserOpsTest extends BaseTest {

    @Autowired
    private ThesisService ts;

    @Test
    public void insertListTest() {
        List thesisList = new ArrayList();

        Thesis t1 = new Thesis();
        Thesis t2 = new Thesis();
        Thesis t3 = new Thesis();

        t1.setName("qq1");
        t2.setName("ww2");
        t3.setName("asd");

        thesisList.add(t1);
        thesisList.add(t2);
        thesisList.add(t3);

        try {
            System.out.println(ts.insertList(thesisList));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

日志输出:

[DEBUG] ==>  Preparing: insert into public.thesis ( name) values ( ? ) 
  [DEBUG] ==> Parameters: qq1(String), ww2(String), asd(String)
  [DEBUG] <==    Updates: 3
  3

返回结果既为所求.
