基本说明：        

        说明：我们可以将MonsterMapperjava接口方法在对应的MonsterlMapper.xml文件中实现外，也可以直接组织MonsterMappere.java接口中声明的方法，直接使用注解来实现，可以作为一种补充的机制在项目中使用.

1、编写了 MonsterAnnotation.java 接口

public interface MonsterAnnotation {@Insert("INSERT INTO mybatis_monster_ (monster_id,age,birthday,email,gender,name,salary)\n" +"        VALUES (#{monster_id},#{age},#{birthday},#{email},#{gender},#{name},#{salary})")public void addMonster(Monster monster);@Delete("DELETE FROM mybatis_monster_ WHERE monster_id=#{monster_id}")public void delMonster(Integer monster_id);@Update(" UPDATE mybatis_monster_ SET age=#{age},birthday=#{birthday},email=#{email},gender=#{gender},name=#{name},salary=#{salary}\n" +"        WHERE monster_id=#{monster_id}")public  void updateMonster(Monster monster);@Select("SELECT * FROM mybatis_monster_ WHERE monster_id=#{monster_id}")public Monster findById(Integer monster_id);@Select("SELECT * FROM mybatis_monster_")public List<Monster> findAllMonster();
}

2、将Monster.Annotation 注册到mybatis-config.xml文件中

 <mappers>
<!--        这里引入或者说注册我们的MonsterMapper.xml文件--><mapper resource="com/bin/mybatis/mapper/MonsterMapper.xml"/><mapper class="com.bin.mybatis.mapper.MonsterAnnotation"/>
<!--        <package name="com.bin.mybatis.mapper"/>--></mappers>

3、测试

  @Testpublic void testAnotation() {Monster monster = new Monster();monster.setAge(200);monster.setBirthday(new Date());monster.setEmail("123@qq.com");monster.setGender(1);monster.setSalary(8928.00);monster.setName("大树精");MonsterAnnotation annotation = sqlsession.getMapper(MonsterAnnotation.class);annotation.addMonster(monster);}
