struts2+ibatis+spring框架整合(一)

公司面试要我做一个struts2+Myibatis整合的实例user表信息给出，有增删改查的操作。

开发技术 struts2+ibatis+spring jsp+java

一.创建web项目导入必需的jar文件

二.创建并编写配置文件，配置文件比较多。可能有点繁琐。

1.创建并编写ApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location">
<value>/WEB-INF/configs/sqlServer.properties</value>
</property>
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>${jdbc.driver}</value>
</property>
<property name="url">
<value>${jdbc.url}</value>
</property>
<property name="username">
<value>${jdbc.user}</value>
</property>
<property name="password">
<value>${jdbc.pwd}</value>
</property>
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:com/test/sqlMapper/mybatis_config.xml" />
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="loginDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="com.test.dao.ILoginDao"/>
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>
<bean id="loginAction" class="com.test.action.LoginAction">
<property name="loginDao" ref="loginDao"></property>
</bean>
</beans>

2.配置数据源当然要有个数据源属性文件了sqlServer.properties

jdbcjdbc.url=jdbc:sqlserver://localhost:1433;DatabaseName=login
jdbc.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbc.user=sa
jdbc.pwd=

我的数据库密码为空pwd当然也要空了。

3.mybatis的配置文件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>
<typeAliases>
<typeAlias alias="userinfo" type="com.test.entity.UserInfo"/>
</typeAliases>
<mappers>
<mapper resource="com/test/sqlMapper/loginMapper.xml"/>
</mappers>
</configuration>

4.在mybatis_config.xml中的中有个映射文件loginMapper.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.test.dao.ILoginDao">
<resultMap type="userinfo" id="userMap">
<id property="id" column="id"/>
<result property="username" column="username"/>
<result property="password" column="password"/>
</resultMap>
<select id="getUser" parameterType="String" resultMap="userMap">
select * from userinfo where username=#{userName}
</select>
</mapper>

5.接下来就是web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<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>

好了所有的配置文件都已经配置好了
三.该写JAVA文件了接口，实体辅助类，还有action

1.写接口 ILoginDao.java

package com.test.dao;
import java.util.List;
public interface ILoginDao {
public List getUser(String userName);
}

2.实体辅助类UserInfo.java

package com.test.entity;
public class UserInfo {
private int id;
private String username;
private String password;
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;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}

3.action 类 LoginAction.java

package com.test.action;
import java.util.List;
import com.test.dao.ILoginDao;
public class LoginAction {
private ILoginDao loginDao;
private String username;
private String password;
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;
}
public ILoginDao getLoginDao() {
return loginDao;
}
public void setLoginDao(ILoginDao loginDao) {
this.loginDao = loginDao;
}
public String execute(){
String userName = getUsername();
String password = getPassword();
System.out.println("userName:"+userName+"\n"+"password:"+password);
List list = loginDao.getUser(userName);
if(list.size()>0){
return "success";
}else{
return "error";
}
}
}

四.该写页面了页面有三个如下

1. login.jsp

<body>
<s:form action="login" method="post">
<s:textfield name="username" label="用户名："></s:textfield>
<s:textfield name="password" label="密码："></s:textfield>
<s:submit value="提交"></s:submit>
</s:form>
</body>

2.success.jsp 就几个字登陆成功
3.error,jsp 就几个字登录失败

五.创建数据库 login 创建表 userinfo 里面就三个字段 id username password 数据库我已经传到这文章里边了，下载后可以直接用

六.好了快启动tomcat看看成功了
