在MyBatis的select、insert、update、delete这些元素中都提到了parameterType这个属性。MyBatis现在可以使用的parameterType有基本数据类型和Java复杂数据类型
根据班级ID查询教师列表
xml文件
- <select id="selectTeacher" parameterType="int" resultType="com.myapp.domain.Teacher">
- select * from Teacher where c_id=#{id}
- </select>
java代码
- List<Teacher> tList = teacherMapper.selectTeacher(2);
- for (Teacher entityTemp : tList) {
- System.out.println(entityTemp.toString());
- }
- <select id="selectTeacher" parameterType="com.myapp.domain.Teacher" resultType="com.myapp.domain.Teacher">
- select * from Teacher where c_id=#{id}
- </select>
- java代码
- Teacher queryTeacher=new Teacher();
- queryTeacher.setId(2);
- List<Teacher> tList = teacherMapper.selectTeacher(queryTeacher);
- for (Teacher entityTemp : tList) {
- System.out.println(entityTemp.toString()); }
