方法一：1.petMapper.xml

<select id="selectAll" parameterType="Map" resultType="Pet">select * from pet limit #{startIndex},#{pageSize} </select>

2.PetDao.java

public List<Pet> selectAll(int currentPage,int pageSize) throws IOException{SqlSession sqlSession = MyBatisUtil.getSqlSession();Map<String,Integer> map=new HashMap<String, Integer>();map.put("startIndex", (currentPage-1)*pageSize);map.put("pageSize",pageSize);List<Pet> pets=sqlSession.selectList("com.mybatis.entity.PetMapper.selectAll",map);return pets;}

3.測試類

public static List<Pet> selectAll(int currentPage,int pageSize) throws IOException {PetDao petDao=new PetDao();List<Pet> pets=petDao.selectAll(currentPage,pageSize);return pets;}public static void main(String[] args) throws IOException, ParseException {PetDao petDao=new PetDao();List<Pet> pets=petDao.selectAll(1, 2);for(Pet pet:pets) {System.out.println(pet);}}

方法二? 1.PetMapper.xml

<select id="getAll" resultType="Pet">select * from pet </select>

2.PetDao.java?

public List<Pet> getAll(int currentPage,int pageSize) throws IOException{SqlSession sqlSession = MyBatisUtil.getSqlSession();RowBounds rowBounds=new RowBounds((currentPage-1)*pageSize,pageSize);List<Pet> pets=sqlSession.selectList("com.mybatis.entity.PetMapper.getAll",null,rowBounds);return pets;}

3.測試類

public static List<Pet> getAll(int currentPage,int pageSize) throws IOException {PetDao petDao=new PetDao();List<Pet> pets=petDao.getAll(currentPage, pageSize);return pets;}public static void main(String[] args) throws IOException, ParseException {PetDao petDao=new PetDao();List<Pet> pets=petDao.getAll(1, 2);for(Pet pet:pets) {System.out.println(pet);}}
