需要在config.xml中注册Java接口
要用class=
查
public interface PeopleMapper {
@Select("select * from people")
List getPeopleList();
}增 可以先开启事务自动提交
public static SqlSession getSqlSession(){
return sqlSessionFactory.openSession(true);
}
}
Mapper.java
```java
public interface PeopleMapper {
@Select("select * from people")
List getPeopleList();
@Insert("insert into people(id, name, age, address) VALUES (#{id},#{name},#{age},#{address})")
int addPeople(People people);
}test
public class PeopleDAOtest {
[@Test](https://my.oschina.net/azibug)
public void print() {
SqlSession sqlSession = MybatisUtils.getSqlSession();
PeopleMapper peopleMapper = sqlSession.getMapper(PeopleMapper.class);
List people = peopleMapper.getPeopleList();
for (People p :people){
System.out.println(p);
}
sqlSession.close();
}
[@Test](https://my.oschina.net/azibug)
public void add(){
SqlSession sqlSession = MybatisUtils.getSqlSession();
PeopleMapper peopleMapper = sqlSession.getMapper(PeopleMapper.class);
peopleMapper.addPeople(new People(6,"圣迭戈",456,"啥地方"));
print();
}
}因为已经自动提交了，所以不需要sqlSession.commit();
删
注解@Param 只能用于基本数据类型 传入的参数只能和sql语句中参数一样 
多个参数 
样例
public interface PeopleMapper {
@Delete("delete people from people where id=#{uid}")
int delPeople(@Param("uid") int i);
}test
public class PeopleDAOtest {
@Test
public void del(){
SqlSession sqlSession = MybatisUtils.getSqlSession();
PeopleMapper peopleMapper = sqlSession.getMapper(PeopleMapper.class);
peopleMapper.delPeople(6);
print();
}
}改
Mapper.java
public interface PeopleMapper {
@Update("update mybatis.people set name=#{name} ,age=#{age} ,address=#{address} where id=#{id}")
int updateP(People people);
}test
public class PeopleDAOtest {
@Test
public void update(){
SqlSession sqlSession = MybatisUtils.getSqlSession();
PeopleMapper peopleMapper = sqlSession.getMapper(PeopleMapper.class);
peopleMapper.updateP(new People(5,"圣迭戈",456,"啥地方"));
print();
}
