(1)web.xml文件(Tomcat使用)

服务器根据配置内容初始化spring框架，springmvc框架和log4j日志框架

(2)springmvc-servlet.xml(Springmvc框架配置文件)

该文件是springmvc框架配置文件，也是它的核心文件

    </property>    
  </bean> -->   
    
</beans>

(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

log4j.appender.file.layout=org.apache.log4j.PatternLayout  
log4j.appender.file.layout.ConversionPattern=[%d] [%t] (%F:%L) %-5p %c - %m%n

log4j.appender.ROLLING_FILE_RSS.layout.ConversionPattern=%d - %c:%L - %-5p %c %x - %m%n 

(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");

(3)service层(业务服务层,UserService.java)

   UserService.java代码如下

package com.archie.service;  
  
import java.util.List;

@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);  
        }  
    }  
}
