SpringMVC+Ibatis框架搭建
阿新 • • 發佈：2019-01-25
這是一個很簡單的SpringMVC+Spring+Ibatis框架 ,下圖是檔案的基本配置
web.xml
在web.xml中配置兩個氫氣，一個是SpringMVC的DispacherServlet,一個是Spring的ContextLoaderListener。
DispacherServlet負責初始化的上下文是和SpringMVC有關的bean，比如handlerMapping,handlerAdapter,viewResolve,ContextLoaderListener負責初始化的上下文是Spring有關的bean,比如dao，service
<?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"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:com/springmvcibatis/config/ControllerApplicationContext.xml</param-value> </init-param> </servlet> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:com/springmvcibatis/config/IbatisApplicationContext.xml classpath*:com/springmvcibatis/config/ServiceApplicationContext.xml </param-value> </context-param> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
ControllerApplicationContext.xml
SpringMVC的相關配置和controller層的配置在這個檔案中
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-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"> <!-- HandlerMapping 解析url，找到執行該url的action--> <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/login.do">loginAction</prop> </props> </property> </bean> <bean id="loginAction" class="com.springmvcibatis.controller.UserAction"> <property name="methodNameResolver"> <ref local="methodNameResolver"/> </property> </bean> <!--檢視解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- webroot到一指定資料夾檔案路徑 --> <property name="prefix" value="/user/"/> <!-- 檢視名稱字尾 --> <property name="suffix" value=".jsp"/> </bean> <!-- 在url中對應具體的方法,通過m後面帶的引數來確定方法 --> <bean id="methodNameResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"> <property name="paramName"><value>m</value></property> <property name="defaultMethodName"><value>execute</value></property> </bean> </beans>
ServiceApplicationContext.xml
Service層的配置，向Service層中注入DAO
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="userService" class="com.springmvcibatis.service.UserService"> <property name="userDAO" ref="userDAO"></property> </bean> </beans>
IbatisApplicationContext.xml
Ibatis配置和DAO的配置，這個ibatis層配置知道怎麼配置，但裡面的具體原理還是不太清楚，有時間弄弄吧
<?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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<!--資料來源配置 這塊用 mysql資料庫 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/test" />
<property name="username" value="root" />
<property name="password" value="123456" />
</bean>
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation">
<value>classpath:com/springmvcibatis/config/SqlMapConfig.xml</value>
</property>
</bean>
<bean id="sqlMapClientTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate">
<property name="sqlMapClient" ref="sqlMapClient"></property>
</bean>
<bean id="userDAO" class="com.springmvcibatis.dao.UserDAOImp">
<property name="sqlMapClientTemplate" ref="sqlMapClientTemplate"></property>
</bean>
</beans>
SqlMapConfig.xml
每個dao對應的sql配置檔案就在這裡面集合，我這裡只有一個dao，所以也就一個這個檔案裡面只配置了一個sql檔案
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<sqlMap resource="com/springmvcibatis/pojo/UserSql.xml"/>
</sqlMapConfig>
UserSql.xml
每個dao對應的sql配置檔案,檔案裡面就是和增刪查改有關的
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-2.dtd">
<sqlMap>
<typeAlias type="com.springmvcibatis.pojo.User" alias="User"/>
<resultMap class="User" id="user">
<result property="id" column="id"></result>
<result property="username" column="username"></result>
<result property="password" column="password"></result>
</resultMap>
<select id="selectByName" parameterClass="java.lang.String" resultMap="user">

</select>
<select id="selectList" resultMap="user">

</select>
<!-- 插入一條並返回主鍵id -->
<insert id="insertUser" parameterClass="User" >
insert into user(username,password) values(#username#,#password#)
<selectKey resultClass="int" keyProperty="id">
select LAST_INSERT_ID() AS VALUE
</selectKey>
</insert>
<delete id="deleteUser" parameterClass="int">

</delete>

import com.springmvcibatis.service.UserService;
public class UserAction extends MultiActionController{
/**

public ModelAndView login(HttpServletRequest request,HttpServletResponse response){
String userName = request.getParameter("userName");

}
}
UserService.java
service層
package com.springmvcibatis.service;
import java.util.List;
import com.springmvcibatis.dao.UserDAO;
import com.springmvcibatis.pojo.User;
public class UserService {
private UserDAO userDAO;
public UserDAO getUserDAO() {
return userDAO;
}
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public boolean selectUserByName(String userName,String password){

}
}
return result;
}
public int insertUser(User user){
int id = userDAO.insertUser(user);
return id;
}
public int deleteUser(int id){
int result = userDAO.deleteUser(id);
return result;
}
}
dao介面
package com.springmvcibatis.dao;
import java.util.List;
import com.springmvcibatis.pojo.User;
public interface UserDAO {
public List<User> selectByName(String userName);
public int insertUser(User user);
public List<User> selectList();
public int deleteUser(int id);
}
dao的實現類，這個繼承了SqlMapClientDaoSupport，還有一個構造方法
package com.springmvcibatis.dao;
import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.springmvcibatis.pojo.User;
public class UserDAOImp extends SqlMapClientDaoSupport implements UserDAO{
public UserDAOImp(){
super();
}
public List<User> selectByName(String userName) {
List<User> list = (List<User>) getSqlMapClientTemplate().queryForList("selectByName", userName);
return list;
}
public int insertUser(User user) {
int id = (Integer) getSqlMapClientTemplate().insert("insertUser", user);
return id;
}
public List<User> selectList() {
List<User> list = getSqlMapClientTemplate().queryForList("selectList");
return list;
}
public int deleteUser(int id) {
int result = getSqlMapClientTemplate().delete("deleteUser", id);
return result;
}
}
User.java
pojo
package com.springmvcibatis.pojo;
public class User {
private int id;
private String username;
private String 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;
}
}
最近找工作找的挺鬱悶的，真的懷疑自己的能力了，工作還沒殺著落，昨天來將這個框架搭好了，已經快工作兩年了還搞大學時候的事情，哎，只怪以前沒有好好學習，現在也沒好好學習，這篇文章沒啥註釋，挺過意不去的，其實ibatis的原始碼自己也沒看，只知道怎麼用，裡面具體怎麼走的還真不知道。主要是給菜鳥看的，也是對自己成長的一個記錄，以後為圍繞這個框架添磚加瓦的，還有AOP，事物管理之類的給加上。何時才能找到工作！！！
