SSM整合XML版(Maven Project)
一、使用IntelliJ IDEA 创建Maven管理的JAVA Web项目
①新建项目，选择Maven Module
在本地磁盘用户的。.m2目录下生成settings文件：
Maven工程搭建完毕！！！
② 开发步骤：
自动从本地仓库下载Jar包：

③ 由于Maven对oracle数据库的不支持，我们需要将Oracle装载到本地仓库，
让Maven使用Oracle
1、配置Maven3.3.9 bin到环境变量
然后可以通过cmd命令行 mvn -version测试有没有测试成功！！！
2、定位到Oracle安装目录的jdbc文件夹
④搭建分层架构---实现添加学生
实体类UserInfo:
package cn.wj.entity;
/**
* Created by WJ on 2017/1/16.
*/
public class UserInfo {
private Integer id;
private String name;
private Integer age;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
dao接口： 无需dao实现类，通过代理生成
public interface IUserInfoDao {
public void add(UserInfo info);
}
service层：
public interface IUserInfoService {
public void add(UserInfo info);
}
service实现类：
public class UserInfoServiceImpl implements IUserInfoService {
private IUserInfoDao dao;
public void add(UserInfo info) {
dao.add(info);
}
public IUserInfoDao getDao() {
return dao;
}
public void setDao(IUserInfoDao dao) {
this.dao = dao;
}
}
控制器类：controller
public class UserInfoController implements Controller {
private IUserInfoService service;
public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
String uname=httpServletRequest.getParameter("uname");
Integer uage=Integer.valueOf(httpServletRequest.getParameter("uage"));
UserInfo info=new UserInfo();
info.setName(uname);
info.setAge(uage);
service.add(info);
return new ModelAndView("/welcome.jsp");
}
public IUserInfoService getService() {
return service;
}
public void setService(IUserInfoService service) {
this.service = service;
}
}
由于是整合MyBatis，需要书写核心配置文件：
小配置：UserInfoDao.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="cn.wj.dao.IUserInfoDao">
<select id="add" parameterType="UserInfo">
insert into userinfo values(SEQ_Num.nextval,#{name},#{age})
</select>
</mapper>
MyBatis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> <package name="cn.wj.entity"/> </typeAliases> <mappers> <package name="cn.wj.dao"/> </mappers> </configuration>
applicationContext.xml：进行植入dao、service、controller、事务管理器、数据源、sessionFactory
index.jsp页面：
<body>
<form action="${pageContext.request.contextPath }/userAction.do" method="post">
用户名：<input name="uname"/> <br/><br/>
年龄:<input name="uage"/><br/><br/>
<input type="submit" value="add"/>
</form>
</body>
Web.xml:进行配置中央调度器
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<!-- 1.针对Spring配置：读取配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 注册ServletContext监听器，创建容器对象，并且将ApplicationContext对象放到Application域中 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 针对SpringMVC的配置：：：：：：中央调度器：本质上一个serlvet 配置的关于SpringmVC组件 -->
<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:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!-- 解决乱码的过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
实现效果：
注：若出现此类异常--org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)
