首先，POJO

/*** @Title: Question.java* @Package com.test.model* @Description: TODO(POJO Question)* Copyright: Copyright (c) 2012 Company China Foreign Exchange Trade System and National Interbank Funding Center.* Building 24,1387 ZhangDong Road, Shanghai, China.* All Rights Reserved. * Company: Insigma HT* @author Ares* @date 2013-06-24 下午3:48:31** Revision History** Date Programmer Notes* --------- --------------------- --------------------------------------------* 2013-06-24 Ares initial*/ package com.test.model;import java.util.Date;/** * * @author Ares* @Describe TODO(POJO Question)* */ public class Question {private String id;private int qorder;private String qname;private String qcontent;private Date updateTime;public String getId() {return id;}public void setId(String id) {this.id = id;}public int getQorder() {return qorder;}public void setQorder(int qorder) {this.qorder = qorder;}public String getQname() {return qname;}public void setQname(String qname) {this.qname = qname;}public String getQcontent() {return qcontent;}public void setQcontent(String qcontent) {this.qcontent = qcontent;}public Date getUpdateTime() {return updateTime;}public void setUpdateTime(Date updateTime) {this.updateTime = updateTime;}}

?

繼續，Mapper

/*** @Title: QuestionDAO.java* @Package com.test.dao* @Description: TODO(Question Mapper)* Copyright: Copyright (c) 2012 Company China Foreign Exchange Trade System and National Interbank Funding Center.* Building 24,1387 ZhangDong Road, Shanghai, China.* All Rights Reserved. * Company: Insigma HT* @author Ares* @date 2013-06-24 下午3:48:31** Revision History** Date Programmer Notes* --------- --------------------- --------------------------------------------* 2013-06-24 Ares initial*/ package com.test.dao;import java.util.List;import org.apache.ibatis.annotations.Insert; import org.apache.ibatis.annotations.InsertProvider; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select;import com.test.model.Question;/** * * @author Ares* @Describe TODO(Question Mapper)* */ public interface QuestionDAO {/*** AddBy Ares* TODO(find all questions)*/@Select("SELECT * FROM Question")public List<Question> findAll();/*** AddBy Ares* TODO(find question by ID)*/@Select("SELECT * FROM Question WHERE ID = #{id}")public Question findByID(@Param("id")String id);/*** AddBy Ares* TODO(just save one question)*/@Insert("INSERT INTO Question VALUES(#{id},#{qorder},#{qname},#{qcontent},#{updateTime})")public void save(Question question);/*** AddBy Ares* TODO(save all questions in list)*/@InsertProvider(type=SqlProvider.class, method="saveAll")public void saveAll(List<Question> list);}

上面的Mapper中，saveAll方法使用了SqlProvider，這個是用作批量添加使用的。

/*** @Title: SqlProvider.java* @Package com.test.dao* @Description: TODO(SqlProvider)* Copyright: Copyright (c) 2012 Company China Foreign Exchange Trade System and National Interbank Funding Center.* Building 24,1387 ZhangDong Road, Shanghai, China.* All Rights Reserved. * Company: Insigma HT* @author Ares* @date 2013-6-24 下午3:48:31** Revision History** Date Programmer Notes* --------- --------------------- --------------------------------------------* 2013-6-24 Ares initial*/ package com.test.dao;import java.text.MessageFormat; import java.util.List; import java.util.Map;import com.test.model.Question;/*** @author Ares* TODO(SqlProvider)*/ public class SqlProvider {private static final String TABLE = "question";public String saveAll(Map<String, List<Question>> params){List<Question> list = (List<Question>)params.get("list");if(list!=null){StringBuffer sb = new StringBuffer("insert into ").append(TABLE).append(" values ");MessageFormat mf = new MessageFormat("(#'{'list[{0}].id}, #'{'list[{0}].qorder}, #'{'list[{0}].qname}, #'{'list[{0}].qcontent}, #'{'list[{0}].updateTime})");for (int i=0; i<list.size(); i++) {sb.append(mf.format(new Object[]{i})); if (i < list.size() - 1) { sb.append(","); } }System.out.println(sb.toString());return sb.toString();}return null;}}

接下來，把配置文件拿過來，

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN""mybatis-3-config.dtd"><configuration><typeAliases><package name="com.test.model"/></typeAliases><environments default="development"><environment id="development"><transactionManager type="jdbc" /><dataSource type="POOLED"><property name="driver" value="com.mysql.jdbc.Driver"/><property name="url" value="jdbc:mysql://localhost:3306/test?useUnicode=true"/><property name="username" value="root"/><property name="password" value="test"/></dataSource></environment></environments><mappers><package name="com.test.dao"/></mappers><!-- <mappers><mapper resource="com/test/model/Question.xml"/></mappers>--> </configuration>

最后，開始測試
