Spring+Struts2+MyBatis（mybatis有代理）整合增删改查
1.创建如下项目结构
2.在项目的WebRoot下的WEB-INF下的lib下添加自己的架包
3.在src下的com.bean包下创建UserInfo.java
package com.bean;
public class UserInfo {
private Integer id;
private String name;
private String password;
private String telephone;
private String isadmin;
public UserInfo() {
}
public UserInfo(Integer id, String name, String password, String telephone,
String isadmin) {
this.id = id;
this.name = name;
this.password = password;
this.telephone = telephone;
this.isadmin = isadmin;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getTelephone() {
return telephone;
}
public void setTelephone(String telephone) {
this.telephone = telephone;
}
public String getIsadmin() {
return isadmin;
}
public void setIsadmin(String isadmin) {
this.isadmin = isadmin;
}
@Override
public String toString() {
return "UserInfo [id=" + id + ", isadmin=" + isadmin + ", name=" + name
+ ", password=" + password + ", telephone=" + telephone + "]";
}
}4.在src下的com.dao包下创建UserInfoDao.java
package com.dao;
import java.util.List;
import com.bean.UserInfo;
/**
* mybatis映射文件的dao接口
* @author pc
*
*/
public interface UserInfoDao {
public List findAll();
//查所有
public UserInfo findUser(UserInfo user);
//条件查询
public void insertUser(UserInfo user);
//插入对象
public void updateUser(UserInfo user);
//修改对象
public void deleteUser(int id);
//条件删除
} 5.在src下的com.dao包下创建UserInfoDao.xml
<mapper namespace="com.dao.UserInfoDao">
<select id="findAll" resultType="user">
select * from userinfo
select>
<select id="findUser" resultType="user" parameterType="user">
select * from userinfo where name=#{name} and password=#{password}
select>
<insert id="insertUser" parameterType="user">
insert into userinfo values(seq_userinfo.nextval,#{name},#{password},#{telephone},#{isadmin})
insert>
<update id="updateUser" parameterType="user">
update userinfo set name=#{name},password=#{password},telephone=#{telephone},isadmin=#{isadmin} where id=#{id}
update>
<delete id="deleteUser" parameterType="int">
delete from userinfo where id=#{id}
delete>
mapper>6.在src下创建mybatis-config.xml
<configuration>
<typeAliases>
<typeAlias type="com.bean.UserInfo" alias="user"/>
typeAliases>
<mappers>
<mapper resource="com/dao/UserInfoDao.xml"/>
mappers>
configuration>7.在src下的com.dao.impl包下创建UserInfoDaoImpl.java

* @author pc
*
*/
public class UserInfoDaoImpl implements UserInfoDao {
private SqlSessionTemplate sqlSession;
/**
* 根据id删除
*/
public void deleteUser(int id) {
//获取代理对象
UserInfoDao dao=sqlSession.getMapper(UserInfoDao.class);
try {
dao.deleteUser(id); //调用代理对象映射的dao接口删除
sqlSession.commit(); //提交事务
System.out.println("删除成功");
} catch (Exception e) {
System.out.println("删除失败");
e.printStackTrace();
}
}
/**
* 查询所有
*/
public List findAll() {
//获取代理对象

try {
list=dao.findAll();
System.out.println("查询所有成功");
} catch (Exception e) {
System.out.println("查询所有失败");
e.printStackTrace();
}
return list;
}
/**

}else{
System.out.println("条件查询参数为空");
}
} catch (Exception e) {
System.out.println("条件查询失败");
e.printStackTrace();
}
return userinfo;
}
/**
*添加
*/
public void insertUser(UserInfo user) {
//获取代理对象
UserInfoDao dao=sqlSession.getMapper(UserInfoDao.class);
try {
if(user!=null){
dao.insertUser(user);
sqlSession.commit(); //提交事务
System.out.println("添加成功");
}else{
System.out.println("添加参数为空");
}
} catch (Exception e) {
System.out.println("添加失败");
e.printStackTrace();
}
}
/**
* 修改对象
*/
public void updateUser(UserInfo user) {
//获取代理对象
UserInfoDao dao=sqlSession.getMapper(UserInfoDao.class);
try {
if(user!=null){
dao.updateUser(user);
sqlSession.commit(); //提交事务
System.out.println("修改成功");
}else{
System.out.println("修改参数为空");
}
} catch (Exception e) {
System.out.println("修改失败");
e.printStackTrace();
}
}
public SqlSessionTemplate getSqlSession() {
return sqlSession;
}
public void setSqlSession(SqlSessionTemplate sqlSession) {
this.sqlSession = sqlSession;
}
} 8.在src下的com.service包下创建UserInfoService.java
package com.service;
import java.util.List;
import com.bean.UserInfo;
/**
* 服务接口
* @author pc
*
*/
public interface UserInfoService {
public List findAll(); //查所有
public UserInfo findUser(UserInfo user);//条件查询
public void insertUser(UserInfo user); //插入对象
public void updateUser(UserInfo user); //修改对象
public void deleteUser(int id); //条件删除
}
UserInfoService.java 9.在src下的com.service.impl包下创建UserInfoServiceImpl.java
package com.service.impl;
import java.util.List;
import com.bean.UserInfo;
import com.dao.UserInfoDao;
import com.dao.impl.UserInfoDaoImpl;
import com.service.UserInfoService;
public class UserInfoServiceImpl implements UserInfoService{
//引入数据层接口
UserInfoDao dao=new UserInfoDaoImpl();
/**
* 删除
*/
public void deleteUser(int id) {
dao.deleteUser(id);
}
/**
* 查所有
*/
public List findAll() {
return dao.findAll();
}
/**
* 条件查询
*/
public UserInfo findUser(UserInfo user) {
return dao.findUser(user);
}
/**
* 插入对象
*/
public void insertUser(UserInfo user) {
dao.insertUser(user);
}
/**
* 修改对象
*/
public void updateUser(UserInfo user) {
dao.updateUser(user);

/**
*
* @author pc
* ActionSupport可以最数据校验
*/
public class UserInfoAction extends ActionSupport {
/**
* 引用服务层对象
*/
private UserInfoService service=new UserInfoServiceImpl();
/**
* 对象用于接收请求中的值
* 必须创建setter和getter方法,代理对象才能获取或设置
*/
private UserInfo user;
/**
* 登录
* @return
*/
public String login(){
if(user!=null){
System.out.println("登录表单值接收到");
UserInfo userinfo=service.findUser(user);
if(userinfo!=null){
System.out.println("登录陈宫");
return SUCCESS;

System.out.println("注册表单值接收到");
service.insertUser(user);
System.out.println("action注册成功");
