近期公司要开发新的项目，要用struts2+mybatis+spring框架，所以学习了下，来自己的博客发表下，希望能给大家带来帮助！
主要实现用户的增删改查操作

1、导入相应的jar包

2、配置web.xml主要是配置struts2和spring

web.xml文件内容如下：

<?xml version="1.0" encoding="utf-8"?> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 
  xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" 
  xsi:schemalocation="http://java.sun.com/xml/ns/javaee  
  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
  <welcome-file-list> 
    <welcome-file>index.jsp</welcome-file> 
  </welcome-file-list> 
 
  <!-- 加载spring的配置文件 --> 
  <listener> 
    <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> 
  </listener> 
  <!-- 配置spring配置文件加载的位置 --> 
  <context-param> 
    <param-name>contextconfiglocation</param-name> 
    <param-value>classpath:beans.xml</param-value> 
  </context-param> 
 
 
  <!-- 配置struts2 --> 
  <filter> 
    <filter-name>struts2</filter-name> 
    <filter-class> 
      org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class> 
  </filter> 
  <filter-mapping> 
    <filter-name>struts2</filter-name> 
    <url-pattern>/*</url-pattern> 
  </filter-mapping> 
 
 
</web-app>

3、配置spring配置文件，主要包括配置数据源、事务、mybaits等
beans.xml配置文件详细如下：

<?xml version="1.0" encoding="utf-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
  xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"  
  xmlns:context="http://www.springframework.org/schema/context" 
  xmlns:aop="http://www.springframework.org/schema/aop" 
  xmlns:tx="http://www.springframework.org/schema/tx" 
  xsi:schemalocation="http://www.springframework.org/schema/beans 
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
      http://www.springframework.org/schema/aop  
      http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
      http://www.springframework.org/schema/tx 
      http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 
      http://www.springframework.org/schema/context 
      http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 
   
  <!-- 采用注释的方式配置bean --> 
  <context:annotation-config /> 
  <!-- 配置要扫描的包 --> 
  <context:component-scan base-package="com.pdsu.edu"></context:component-scan> 
   
  <!--proxy-target-class="true"强制使用cglib代理  如果为false则spring会自动选择--> 
  <aop:aspectj-autoproxy proxy-target-class="true"/> 
   
  <!-- 数据库配置文件位置 --> 
  <context:property-placeholder location="classpath:jdbc.properties" /> 
   
  <!-- 配置dbcp数据源 --> 
  <bean id="datasource" class="org.apache.commons.dbcp.basicdatasource" destroy-method="close"> 
    <property name="driverclassname" value="${jdbc.driverclassname}" /> 
    <property name="url" value="${jdbc.url}" /> 
    <property name="username" value="${jdbc.username}" /> 
    <property name="password" value="${jdbc.password}" /> 
    <!-- 队列中的最小等待数 --> 
    <property name="minidle" value="${jdbc.minidle}"></property> 
    <!-- 队列中的最大等待数 --> 
    <property name="maxidle" value="${jdbc.maxidle}"></property> 
    <!-- 最长等待时间，单位毫秒 --> 
    <property name="maxwait" value="${jdbc.maxwait}"></property> 
    <!-- 最大活跃数 --> 
    <property name="maxactive" value="${jdbc.maxactive}"></property> 
    <property name="initialsize" value="${jdbc.initialsize}"></property> 
  </bean> 
   
  <!-- 配置mybitassqlsessionfactorybean --> 
  <bean id="sqlsessionfactory" class="org.mybatis.spring.sqlsessionfactorybean"> 
    <property name="datasource" ref="datasource" /> 
    <property name="configlocation" value="classpath:mybatis.xml"></property> 
  </bean> 
   
  <!-- 配置sqlsessiontemplate --> 
  <bean id="sqlsessiontemplate" class="org.mybatis.spring.sqlsessiontemplate"> 
    <constructor-arg name="sqlsessionfactory" ref="sqlsessionfactory" /> 
  </bean> 
   
  <!-- 事务配置 --> 
  <bean id="transactionmanager" class="org.springframework.jdbc.datasource.datasourcetransactionmanager"> 
    <property name="datasource" ref="datasource" /> 
  </bean> 
   
  <!-- 使用annotation注解方式配置事务 --> 
  <tx:annotation-driven transaction-manager="transactionmanager"/> 
 
</beans>

4.jdbc配置文件详细

 jdbc.driverclassname=com.mysql.jdbc.driver 
jdbc.url=jdbc:mysql://localhost:3306/operationlog 
jdbc.username=root 
jdbc.password= 
jdbc.maxactive = 2 
jdbc.maxidle =5 
jdbc.minidle=1 
jdbc.initialsize =3 
jdbc.maxwait =3000

5、配置mybatis主配置文件：

<?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> 
  <typealiases> 
    <typealias alias="user" type="com.pdsu.edu.domain.user"/> 
  </typealiases> 
  <mappers> 
    <mapper resource="com/pdsu/edu/domain/sqlmappers/user.xml" /> 
  </mappers> 
</configuration>

6、配置user.xml文件

<?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.pdsu.edu.domain.user"> 
   
  <resultmap type="com.pdsu.edu.domain.user" id="userresult"> 
    <result property="id" column="id" jdbctype="integer" javatype="java.lang.integer" /> 
    <result property="username" column="username" /> 
    <result property="password" column="password" /> 
  </resultmap> 
  <select id="userlogin" parametertype="user" resultmap="userresult"> 
    select * from user  
    where  
      username=#{username} and password=#{password} 
  </select> 
 
  <select id="selectalluser" resultmap="userresult"> 
    select * from user 
  </select> 
 
  <select id="finduserbyid" parametertype="int" resultmap="userresult"> 
    select * 
    from user where id=#{id} 
  </select> 
 
  <insert id="insertuser" parametertype="user"> 
   <![cdata[ 
    insert into 
    user(username,password) values(#{username},#{password}) 
    ]]> 
  </insert> 
 
  <update id="updateuser" parametertype="user"> 
    update user set 
    username=#{username},password=#{password} where id=#{id} 
  </update> 
   
  <delete id="deleteuser" parametertype="int"> 
    delete from user where 
    id=#{id} 
  </delete> 
 
</mapper>

7、user实体的写法

public class user implements serializable { 
  private static final long serialversionuid = -4415990281535582814l; 
  private integer id; 
  private string username; 
  private string password; 
 
  public integer getid() { 
    return id; 
  } 
 
  public void setid(integer 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; 
  } 
 
  @override 
  public string tostring() { 
    return "user [id=" + id + ", password=" + password + ", username=" + username + "]"; 
  } 
 
  @override 
  public int hashcode() { 
    final int prime = 31; 
    int result = 1; 
    result = prime * result + ((id == null) ? 0 : id.hashcode()); 
    return result; 
  } 
 
  @override 
  public boolean equals(object obj) { 
    if (this == obj) 
      return true; 
    if (obj == null) 
      return false; 
    if (getclass() != obj.getclass()) 
      return false; 
    user other = (user) obj; 
    if (id == null) { 
      if (other.id != null) 
        return false; 
    } else if (!id.equals(other.id)) 
      return false; 
    return true; 
  } 
}

8、userdao的写法

public interface userdao { 
 
  public abstract void insertuser(user user); 
 
  public abstract void updateuser(user user); 
 
  public abstract void deleteuser(integer userid); 
 
  public abstract user finduserbyid(integer userid); 
 
  public abstract list<user> findall(); 
 
  public abstract user userlogin(user user); 
 
}

9、userdao的实现

@repository 
public class userdaoimpl implements userdao { 
  private final string insert_user = "insertuser"; 
  private final string update_user = "updateuser"; 
  private final string delete_user = "deleteuser"; 
  private final string find_user_byid = "finduserbyid"; 
  private final string select_all_user = "selectalluser"; 
  private final string user_login = "userlogin"; 
  @autowired 
  private sqlsessiontemplate sqlsessiontemplate; 
 
  public void insertuser(user user) { 
    sqlsessiontemplate.insert(insert_user, user); 
  } 
 
  public void updateuser(user user) { 
    sqlsessiontemplate.update(update_user, user); 
  } 
 
  public void deleteuser(integer userid) { 
    sqlsessiontemplate.delete(delete_user, userid); 
  } 
 
  public user finduserbyid(integer userid) { 
    return sqlsessiontemplate.selectone(find_user_byid, userid); 
  } 
 
  public list<user> findall() { 
    return sqlsessiontemplate.selectlist(select_all_user); 
  } 
 
  public user userlogin(user user) { 
    return sqlsessiontemplate.selectone(user_login, user); 
  } 
}

10、userservice接口

public interface userservice { 
 
  // 添加用户 
  public abstract void adduser(user user); 
 
  public abstract void updateuser(user user); 
 
  public abstract void deleteuser(integer userid); 
 
  public abstract user finduserbyid(integer userid); 
 
  public abstract list<user> findalluser(); 
 
  public abstract user login(user user); 
 
}

11、userservice接口的实现

@service 
@transactional 
public class userserviceimpl implements userservice { 
 
  @autowired 
  private userdao userdao; 
 
  // 添加用户 
  public void adduser(user user) { 
    userdao.insertuser(user); 
  } 
 
  // 更新用户 
  public void updateuser(user user) { 
    userdao.updateuser(user); 
  } 
 
  public void deleteuser(integer userid) { 
    userdao.deleteuser(userid); 
  } 
 
  public user finduserbyid(integer userid) { 
    return userdao.finduserbyid(userid); 
  } 
 
  public list<user> findalluser() { 
    return userdao.findall(); 
  } 
 
  public user login(user user) { 
    return userdao.userlogin(user); 
  } 
}

12、配置struts2

<?xml version="1.0" encoding="utf-8" ?> 
<!doctype struts public "-//apache software foundation//dtd struts configuration 2.1//en" "http://struts.apache.org/dtds/struts-2.1.dtd"> 
<struts>  
   <constant name="struts.i18n.encoding" value="utf-8"/> 
      <!-- 指定默认编码集 ，作用于httpservletrequest的setcharacterencoding（）和freemarker，vilocity的输出 --> 
  <constant name="struts.configuration.xmlreload" value="true"/> 
      <!-- 当struts配置文件修改时是否自动加载 --> 
  <constant name="struts.devmode" value="true"/> 
      <!-- 开发模式下打印详细的错误信息 --> 
  <constant name="struts.ui.theme" value="xhtml"/> 
   
  <package name="user" namespace="/user" extends="struts-default"> 
    <action name="user_*" class="useraction" method="{1}"> 
      <result name="success" type="redirectaction">user_queryalluser.action</result> 
      <result name="input">/index.jsp</result> 
      <result name="userlist">/userlist.jsp</result> 
      <result name="adduser">/useradd.jsp</result> 
      <result name="updateuser">/userupdate.jsp</result> 
    </action> 
  </package> 
</struts>

13、useraction具体实现

@controller 
@scope("prototype") 
public class useraction extends actionsupport { 
  @autowired 
  private userservice userservice; 
  private user user; 
  private list<user> userlist; 
 
  public string execute() throws exception { 
    return null; 
  } 
 
  public string login() { 
    if (user != null) { 
      user user2 = userservice.login(user); 
      if (user2 != null) { 
        return success; 
      } 
    } 
    this.addfielderror("user.username", "用户名或密码错误!"); 
    return input; 
  } 
 
  public string addui() { 
    return "adduser"; 
  } 
 
  public string updateui() { 
    user = userservice.finduserbyid(user.getid()); 
    return "updateuser"; 
  } 
 
  public string add() { 
    userservice.adduser(user); 
    return success; 
  } 
 
  public string delete() { 
    userservice.deleteuser(user.getid()); 
    return success; 
  } 
 
  public string update() { 
    userservice.updateuser(user); 
    return success; 
  } 
 
  public user getuser() { 
    return user; 
  } 
 
  public void setuser(user user) { 
    this.user = user; 
  } 
 
  public string queryalluser() { 
    userlist = userservice.findalluser(); 
    return "userlist"; 
  } 
 
  public list<user> getuserlist() { 
    return userlist; 
  } 
 
  public void setuserlist(list<user> userlist) { 
    this.userlist = userlist; 
  } 
 
}

14、登录页面的实现

<%@ page language="java" import="java.util.*" pageencoding="utf-8"%> 
<%@ taglib prefix="s" uri="/struts-tags"%> 
<% 
string path = request.getcontextpath(); 
string basepath = request.getscheme()+"://"+request.getservername()+":"+request.getserverport()+path+"/"; 
%> 
 
<!doctype html public "-//w3c//dtd html 4.01 transitional//en"> 
<html> 
 <head> 
  <base href="<%=basepath%>"> 
   
  <title>用户登录</title> 
  <meta http-equiv="pragma" content="no-cache"> 
  <meta http-equiv="cache-control" content="no-cache"> 
  <meta http-equiv="expires" content="0">

  <s:head/> 
 </head> 
  
 <body> 
  <center> 
    <h1>用户登录</h1> 
    <s:a action="user_addui" namespace="/user">添加新用户</s:a> 
    <s:form action="user_login" namespace="/user" method="post"> 
      <s:textfield label="用户名" name="user.username"></s:textfield> 
      <s:password label="密码" name="user.password"></s:password> 
      <s:submit value="登录"></s:submit> 
    </s:form> 
  </center> 
 </body> 
</html>

15、添加页面

<%@ page language="java" import="java.util.*" pageencoding="utf-8"%> 
<%@ taglib prefix="s" uri="/struts-tags"%> 
<!doctype html public "-//w3c//dtd html 4.01 transitional//en"> 
<html> 
 <head> 
   
  <title>添加新用户</title> 
   
  <meta http-equiv="pragma" content="no-cache"> 
  <meta http-equiv="cache-control" content="no-cache"> 
  <meta http-equiv="expires" content="0">   
 
 </head> 
  
 <body> 
  <center> 
    <h1>添加新用户</h1> 
    <s:form action="user_add" namespace="/user" method="post"> 
      <s:textfield label="用户名" name="user.username"></s:textfield> 
      <s:password label="密码" name="user.password"></s:password> 
      <s:submit value="提交"></s:submit> 
    </s:form> 
  </center> 
 </body> 
</html>

16、修改页面

<%@ page language="java" import="java.util.*" pageencoding="utf-8"%> 
<%@ taglib prefix="s" uri="/struts-tags"%> 
<!doctype html public "-//w3c//dtd html 4.01 transitional//en"> 
<html> 
 <head> 
   
  <title>修改用户</title> 
   
  <meta http-equiv="pragma" content="no-cache">

    <h1>修改用户</h1> 
    <s:form action="user_update" namespace="/user" method="post"> 
      <s:hidden name="user.id"></s:hidden> 
      <s:textfield label="用户名" name="user.username"></s:textfield> 
      <s:password label="密码" name="user.password"></s:password> 
      <s:submit value="提交"></s:submit> 
    </s:form> 
  </center> 
 </body> 
</html>

17、列表页面

<%@ page language="java" import="java.util.*" pageencoding="utf-8"%> 
<%@ taglib prefix="s" uri="/struts-tags"%> 
<!doctype html public "-//w3c//dtd html 4.01 transitional//en"> 
<html> 
 <head> 
   
  <title>用户列表</title> 
   
  <meta http-equiv="pragma" content="no-cache"> 
  <meta http-equiv="cache-control" content="no-cache"> 
  <meta http-equiv="expires" content="0">   
 
 </head> 
  
 <body> 
  <center> 
    <h2>用户列表</h2> 
    <h3><s:a action="user_addui" namespace="/user">添加新用户</s:a> </h3> 
    <table width="90%" border="1"> 
      <tr> 
        <th>用户id</th>
