MyBatis+Spring 事务管理
在网上查了MyBatis+Spring的结合,真的是太多太多了,可是没有几个代码是完整的..这两项整合花了我两天时间,终于被我整合完成...其实也很简单,原 因:JAR包的问题... 由于Ibatis被改名为MyBatis,所以,网上很多都是有关Ibatis而MyBatis却很少很少... 本文以MyBatis3.0.6 + Spring3.0.6为例结合(一定要这个版本才行):出处：http://kinglixing.blog.51cto.com/3421535/723870
实体类:Emp.java
package com.lixing.scm.entity; public class Emp { private String id; private String name; private String sex; private int age; private String phone; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } } 定义实体内操作接口:EmpMapper.java
package com.lixing.scm.test.mapper; import java.util.List; import java.util.Map; import com.lixing.scm.entity.Emp; public interface EmpMapper { void insertEmp(Emp emp); List<Emp> getAllEmp(); Emp getById(String id); void deleteEmp(String id); void updateEmp(Map<String,Object> map); } 定义实体类操作接口的映射文件:EmpMapper.xml
