(4)jdbc.properties(数据源属性文件)

数据源连接信息的源出处，目前配置了三种数据库Oracle，DB2和Mysql

# Database Connectivity
# Oracle
#driver = oracle.jdbc.driver.OracleDriver
#url = jdbc:oracle:thin:@localhost:1521:oracl
#username = scott
#password = tiger  

# DB2
#driver = com.ibm.db2.jcc.DB2Driver
#url = jdbc:db2://192.168.1.2:50000/mydb
#username = root
#password = root  

# Mysql
driver = com.mysql.jdbc.Driver
url = jdbc:mysql://localhost:3306/mydb?useUnicode=true&characterEncoding=utf-8
username = root
password = 1234
initialPoolSize = 1
minPoolSize = 1
maxPoolSize =10

(5)log4j.properties(log4j框架属性文件)

# log4j.properties
log4j.rootLogger=warn,console  

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout

(6)sqlMapConfig.xml(Ibatis框架配置文件)

该文件主要负责指定sql映射文件，即与model层对象对应的映射文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
  <!-- 配置settings -->
  <settings lazyLoadingEnabled="true" useStatementNamespaces="false"/>  

  <!-- 配置sql映射文件 -->
  <sqlMap resource="com/archie/model/User.xml"/>
</sqlMapConfig>

6.Java代码编写

根据包目录，可以看出分成model层,dao层,service层和web层,另外附加test层,用于java环境测试

(1)model层(User.java+User.xml)

   User.java代码

package com.archie.model;  

public class User {  

    private int id;
    private String username;
    private String password;   

    public User(){  

    }  

    public User(int id){
        this.id = id;
    }  

    public User(int id, String username){
        this.id = id;
        this.username = username;
    }  

    public User(String username, String password) {
        this.username = username;
        this.password = password;
    }  

    public User(int id, String username, String password){
        this.id = id;
        this.username = username;
        this.password = password;
    }  

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
}

User.xml代码

(model层对象的sql映射文件,被dao层调用,本质是sql语句集合,所有相关的sql均于此)

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="User">  

    <typeAlias alias="User" type="com.archie.model.User"/>  

    <select id="findAllUser" resultClass="User" >
        select * from t_user
    </select>
    <select id="findUserByID" resultClass="User" parameterClass="int">
        select * from t_user where id=#id#
    </select>  

    <select id="getTotalCount" resultClass="int">
        select count(*) from t_user
    </select>  

    <select id="searchUsers" resultClass="User" parameterClass="User">
        select * from t_user
        <dynamic prepend="where">
            <!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 -->
            <isNotEmpty prepend="and" property="username">
                (username like '%$username$%')
            </isNotEmpty>
            <isNotEmpty prepend="and" property="password">
                (password like '%$password$%')
            </isNotEmpty>
        </dynamic>
    </select>  

    <select id="findUserByNameAndPassword" resultClass="User" parameterClass="User">
        select * from t_user where username=#username# and password=#password#
    </select>  

    <insert id="insertUser" parameterClass="User">
        insert into t_user(id,username,password) values(null,#username#,#password#)
    </insert>  

    <update id="updateUser" parameterClass="User">
        update t_user
        set username = #username#,
            password=#password#
        where id=#id#
    </update>  

    <delete id="deleteUser" parameterClass="int">
        delete from t_user where id=#id#
    </delete>  

    <delete id="deleteUserByLike" parameterClass="User">
        delete from t_user
        <dynamic prepend="where">
            <!-- 模糊查询，用$表示文本替换，而用#表示替换PrepareStatement中的?号 -->
            <isNotEmpty prepend="and" property="username">
                (username like '%$username$%')
            </isNotEmpty>
            <isNotEmpty prepend="and" property="password">
                (password like '%$password$%')
            </isNotEmpty>
        </dynamic>
    </delete>  

</sqlMap>

(2)dao层(数据服务层,BaseDao.java+UserDao.java)

   BaseDao.java(公共Dao,其他Dao均继承它)

package com.archie.dao;  

import javax.annotation.PostConstruct;
import javax.annotation.Resource;  

import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;  

import com.ibatis.sqlmap.client.SqlMapClient;  

public class BaseDao extends SqlMapClientDaoSupport {  

    @Resource(name="sqlMapClient")  //通过bean名称注入
    private SqlMapClient sqlMapClient;  

    @PostConstruct  //完成sqlMapClient初始化工作
    public void initSqlMapClient(){
        super.setSqlMapClient(sqlMapClient);
    }
} 

UserDao.java(user数据服务层)

package com.archie.dao;  

import java.util.List;  

import org.springframework.stereotype.Component;
import com.archie.model.User;  

@Component  //将UserDao类注入到bean里面
public class UserDao extends BaseDao {  

    public boolean addUser(User user) throws Exception{
        User bean = (User)getSqlMapClientTemplate().insert("insertUser", user);
        return bean != null ? true : false;
    }  

    public boolean deleteUser(int id) throws Exception{
        int result = getSqlMapClientTemplate().delete("deleteUser", id);
        return result > 0 ? true : false;
    }  

    public User getUserById(int id) throws Exception{
        return (User)getSqlMapClientTemplate().queryForObject("findUserByID", id);
    }  

    @SuppressWarnings("unchecked")
    public List getAllUsers() throws Exception{
        return getSqlMapClientTemplate().queryForList("findAllUser");
    }  

    public boolean updateUser(User user) throws Exception{
        int result = getSqlMapClientTemplate().update("updateUser", user);
        return result > 0 ? true : false;
    }  

    public User getUserByNameAndPassword(User user) throws Exception{
        return (User)getSqlMapClientTemplate().queryForObject("findUserByNameAndPassword", user);
    }  

    public int getTotalCount() throws Exception{
        return (Integer)getSqlMapClientTemplate().queryForObject("getTotalCount");
    }  

    @SuppressWarnings("unchecked")
    public List getUsersByLike(User user) throws Exception{
        return getSqlMapClientTemplate().queryForList("searchUsers", user);
    }  

    public int deleteUserByLike(User user) throws Exception{
        int result = getSqlMapClientTemplate().delete("deleteUserByLike", user);
        if (result > 0) {
            System.out.println("模糊删除成功！");
        }else {
            System.out.println("没有匹配的记录1");
        }
        return result;
    }
}  

(3)service层(业务服务层,UserService.java)

   UserService.java代码如下

package com.archie.service;  

import java.util.List;  

import javax.annotation.Resource;  

import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;  

import com.archie.dao.UserDao;
import com.archie.model.User;  

@Component  //将UserService类注入到bean里面
@Transactional  //注入事务管理
public class UserService {  

    @Resource(name="userDao")  // 通过名称注入到bean里面
    private UserDao userDao;  

    public User login(User user) throws Exception{
        return userDao.getUserByNameAndPassword(user);
    }  

    public void addUser(User user) throws Exception{
        userDao.addUser(user);
    }  

    public void deleteUser(int id) throws Exception{
        boolean bool = userDao.deleteUser(id);
        if (!bool) {
            System.out.println("删除的记录不存在！");
            throw new RuntimeException();
        }
    }  

    public User getUserById(int id) throws Exception{
        User user = userDao.getUserById(id);
        if (user == null) {
            return null;
        }
        return userDao.getUserById(id);
    }  

    public void updateUser(User user) throws Exception{
        userDao.updateUser(user);
    }  

    public int getTotalCount() throws Exception{
        return userDao.getTotalCount();
    }  

    @SuppressWarnings("unchecked")
    public List getUsersByLike(User user) throws Exception{
        return userDao.getUsersByLike(user);
    }  

    public int deleteUserByLike(User user) throws Exception{
        return userDao.deleteUserByLike(user);
    }  

    public void insertUsers(List<User> list) throws Exception{
        for (int i = 0; i < list.size(); i++) {
            if (i > 3) {
                System.out.println("列表太长，中断事务");
                throw new RuntimeException("中断事务异常,当列表长度大于3的时候故意抛出，看看事务是否回滚");
            }
            User user = list.get(i);
            userDao.addUser(user);
