测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-biz.xml")
public class AuthorTest {
    @Resource
    private AuthorService authorService;

    @Test
    public void addAuthor(){
        Author author= new Author();
        author.setName("张茹娟");
        author.setIntro("宠辱不惊，看庭前花开花落，去留无意，望天上云卷云舒。");
        author.setCreateAt(new Date().getTime());
        author.setUpdateAt(new Date().getTime());
        author.setUpdateBy("超级管理员");
        author.setCreateBy("超级管理员");
        int num = authorService.addAuthor(author);
        System.out.println(num);
    }
    @Test
    public void findAuthor(){
        Author author = authorService.findAuthor(2L);
        System.out.println(author);
    }
    @Ignore
    public void updateAuthor(){
        Author author= new Author();
        author.setId(1);
        author.setName("沈红");
        author.setIntro("人生恰如三月花，倾我一生一世念。来如飞花散似烟，醉里不知年华限。");
        author.setUpdateAt(new Date().getTime());
        author.setUpdateBy("超级管理员");
        int num = authorService.updateAuthor(author);
        System.out.println(num);
    }
    @Ignore
    public void deleteAuthor(){
        int num = authorService.deleteAuthor(2L);
        System.out.println(num);
    }
}

service和impl

@Service("authorService")
public interface AuthorService {
    Author findAuthor(Long id);
    int updateAuthor(Author author);
    int addAuthor(Author author);
    int deleteAuthor(Long id);
}

@Service
public class AuthorServiceImpl implements AuthorService {
    @Resource
    private AuthorDao authorDao;
    @Override
    public Author findAuthor(Long id) { return authorDao.findAuthor(id); }
    @Override
    public int updateAuthor(Author author) {return authorDao.updateAuthor(author); }
    @Override
    public int addAuthor(Author author) {return authorDao.addAuthor(author); }
    @Override
    public int deleteAuthor(Long id) {return authorDao.deleteAuthor(id); }
}

Dao层

@Repository("authorDao")
public interface AuthorDao {
    Author findAuthor(Long id);
    int updateAuthor(Author author);
    int addAuthor(Author author);
    int deleteAuthor(Long id);
}
