1.通过for each标签拼接sql（数量较少的时候使用）

　　a.拼接values（）

　　public int addPersons(@Param("persons") List<Person> persons);//接口

<insert id="addPersons"> insert into person(username,email,gender) VALUES <foreach collection="persons" item="person" separator=";"> (#{person.username},#{person.email},#{person.gender}) </foreach> </insert><!--类似的效果 insert into person(username,email,gender) VALUES("zhangsan","zhangsan@163.com","F"),("lisi","lisi@163.com","F"),... -->

　　b.拼接insert sql语句（需设置属性allowMultiQueries=true）

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mybatis?allowMultiQueries=true //需设置属性
jdbc.username=root
jdbc.password=123

public int addPersons(@Param("persons") List<Person> persons);//接口

<insert id="addPersons"> insert into person(username,email,gender) VALUES <foreach collection="persons" item="person" separator=","> (#{person.username},#{person.email},#{person.gender}) </foreach> </insert><!--类似的效果 insert into person(username,email,gender) VALUES("tom","zhangsan@163.com","F"); insert into person(username,email,gender) VALUES("jerry","lisi@163.com","F");...-->

2.基于Session的ExecutorType进行批量添加

先定义一条插入一条记录的方法

public int addPerson(User user); //接口

<insert id="addPerson" parameterType="user"> insert into t_user(username,address) VALUES (#{username},#{address}) </insert>

在java代码中使用

public void testBatchForExecutor() { SqlSession sqlSession = this.getSqlSessionFactory().openSession(ExecutorType.BATCH); //通过session设置ExecutorType开启批量添加，类似jdbc的addBatch操作 PersonMapper personMapper = sqlSession.getMapper(PersonMapper.class); for (int i = 0; i <10000 ; i++) { personMapper.addPerson(new User("jerry","bj")); } sqlSession.commit(); sqlSession.close(); }
