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<UserInfo> 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

<?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
  <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

<?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd" >
  <configuration>
    <!-- mybatis映射文件的别名配置 -->
    <typeAliases>
      <typeAlias type="com.bean.UserInfo" alias="user"/>
    </typeAliases>

    <!-- 注册mybatis的映射文件 -->
   <mappers>
     <mapper resource="com/dao/UserInfoDao.xml"/>
   </mappers>
 </configuration>

7.在src下的com.dao.impl包下创建UserInfoDaoImpl.java

      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<UserInfo> findAll() {
       //获取代理对象
         UserInfoDao dao=sqlSession.getMapper(UserInfoDao.class);
          List<UserInfo> list=null;
          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;
      }

      /**
      * 条件查询
       */
      public UserInfo findUser(UserInfo user) {
          //获取代理对象
          UserInfoDao dao=sqlSession.getMapper(UserInfoDao.class);
          UserInfo userinfo=null;
          try {
              if(user!=null){
                  userinfo=dao.findUser(user);
                  System.out.println("条件查询成功");
              }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

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<UserInfo> 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);
    }


    public UserInfoDao getDao() {
        return dao;
    }
    public void setDao(UserInfoDao dao) {
        this.dao = dao;
    }

 * 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;

            }else{
                return ERROR;
            }


        }else{
            System.out.println("登录表单值没有接收到");
            return ERROR;

        }
    }

    /**
     * 注册
     * @return
     */
    public String register(){
        if(user!=null){
            System.out.println("注册表单值接收到");
            service.insertUser(user);
            System.out.println("action注册成功");
            return SUCCESS;

        }else{
            System.out.println("注册表单值没有接收到");
            return ERROR;

        }
    }

    public UserInfoService getService() {
        return service;
    }

    public void setService(UserInfoService service) {
        this.service = service;
    }

    public UserInfo getUser() {

  <!-- 中文乱码处理 -->
  <constant name="struts.i18n.encoding" value="UTF-8"/>


    <package name="default" namespace="/" extends="struts-default">


       <!-- method是对应action类的有返回值的方法名 -->
        <!-- 登录,注册,通配符设置,动态调用方法,*表示Login或register -->
        <action name="*" class="userAction" method="{1}">
          <result name="input">{1}.jsp</result>
          <result name="success">success.jsp</result>
