ssm整合
ssm整合
一 先添加spring框架
1.创建一个maven项目
2.在pom.xml中添加spring jar包
<!-- Spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.18.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>4.3.18.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.3.18.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.3.18.RELEASE</version>
</dependency>
3.创建基本mvc结构
pojo层:
Items类
package com.test.pojo;
import java.util.Date;
public class Items {
private int id;
private String name;
private float price;
private String detail;
private String pic;
private Date createtime;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public float getPrice() {
return price;
}
public void setPrice(float price) {
this.price = price;
}
public String getDetail() {
return detail;
}
public void setDetail(String detail) {
this.detail = detail;
}
public String getPic() {
return pic;
}
public void setPic(String pic) {
this.pic = pic;
}
public Date getCreatetime() {
return createtime;
}
public void setCreatetime(Date createtime) {
this.createtime = createtime;
}
@Override
public String toString() {
return "Items{" +
"id=" + id +
", name='" + name + '\'' +
", price=" + price +
", detail='" + detail + '\'' +
", pic='" + pic + '\'' +
", createtime=" + createtime +
'}';
}
}
dao层
接口 IItemsDao
package com.test.dao;
import com.test.pojo.Items;
import java.util.List;
public interface IItemsDao {
public List<Items> selectItems();
}
实现类 ItemsDao
package com.test.dao.impl;
import com.test.dao.IItemsDao;
import com.test.mapper.ItemsMapper;
import com.test.pojo.Items;
import org.springframework.stereotype.Component;
import java.io.InputStream;
import java.util.List;
public class ItemsDao implements IItemsDao {
public ItemsDao()
{
}
public List<Items> selectItems()
{
return null;
}
}
service层
接口:IItemsService
package com.test.service;
import com.test.pojo.Items;
import java.util.List;
public interface IItemsService {
public List<Items> selectItems();
}
实现类:ItemsService
package com.test.service.impl;
import com.test.dao.IItemsDao;
import com.test.mapper.ItemsMapper;
import com.test.pojo.Items;
import com.test.service.IItemsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
public class ItemsService implements IItemsService {
private IItemsDao itemsDao;
public List<Items> selectItems()
{
return itemsDao.selectItems();
}
}
4.创建spring的配置文件
applicationContext-ioc.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"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
</beans>
5.在配置文件中添加注解扫描包
<?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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 设置注解 扫描 的包 -->
<context:component-scan base-package="com.test" />
</beans>
-
在mvc各层中添加注解
package com.test.dao.impl; import com.test.dao.IItemsDao; import com.test.mapper.ItemsMapper; import com.test.pojo.Items; import org.springframework.stereotype.Component; import java.io.InputStream; import java.util.List; @Component public class ItemsDao implements IItemsDao { public ItemsDao() { } public List<Items> selectItems() { return null; } }
@Service
public class ItemsService implements IItemsService {
@Autowired
private IItemsDao itemsDao;
public List<Items> selectItems()
{
return itemsDao.selectItems();
}
}
二.在spring中引入mybatis
1.导入mybatis jar包
<!-- 导入mybatis需要的jar包 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.37</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.4.6</version>
</dependency>
<dependency>
<groupId>com.mchange</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.5.2</version>
</dependency>
<!-- 配置日志信息-->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
2.导入spring整合mybatis架包
<!-- spring 整合 mybatis-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.3.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.18.RELEASE</version>
</dependency>
3.创建mapper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.test.mapper.ItemsMapper">
<select id="selectItems" resultType="Items">
select * from items;
</select>
</mapper>
4.创建mapper文件的代理接口
package com.test.mapper;
import com.test.pojo.Items;
import java.util.List;
public interface ItemsMapper {
public List<Items> selectItems();
}
5.创建mybatis配置文件
mybatis.xml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>
<!-- 设置日志的输出方法 -->
<settings>
<setting name="logImpl" value="STDOUT_LOGGING" />
</settings>
<!-- 给pojo下面的类设置别名-->
<typeAliases>
<package name="com.test.pojo"/>
</typeAliases>
<mappers>
<mapper resource="com/test/mapper/ItemsMapper.xml"/>
</mappers>
</configuration>
6. 创建db.properties文件
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123
7. 修改applicationContext-ioc.xml文件
将之前在mybatis文件中配置的数据源 交给spring来管理，并创建sqlSessionFactory对象
<?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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 设置注解 扫描 的包 -->
<context:component-scan base-package="com.test" />
<!-- 导入db.properties文件 -->
<context:property-placeholder location="classpath:db.properties"></context:property-placeholder>
<!-- 创建一个连接池对象 -->
<bean id="comboPooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}" />
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- 创建sqlSessionfactory对象-->
<bean id="sqlSessionfactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="comboPooledDataSource"/>
<property name="configLocation" value="classpath:mybatis.xml"/>
</bean>
</beans>
8.修改dao层
package com.test.dao.impl;
import com.test.dao.IItemsDao;
import com.test.mapper.ItemsMapper;
import com.test.pojo.Items;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.io.InputStream;
import java.util.List;
@Component
public class ItemsDao implements IItemsDao {
@Autowired
private SqlSessionFactory sqlSessionFactory;
public ItemsDao()
{
}
public List<Items> selectItems()
{
SqlSession sqlSession= sqlSessionFactory.openSession();
ItemsMapper itemsMapper= sqlSession.getMapper(ItemsMapper.class);
List<Items> itemsList= itemsMapper.selectItems();
return itemsList;
}
}
9.在pom.xml文件中添加mapper.xml文件的路径
在build标签中添加
<resources>
<resource>
<!-- 将Mapper的映射文件拷贝出来 -->
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
10.测试
@Test
public void fun()
{
ClassPathXmlApplicationContext classPathXmlApplicationContext=new ClassPathXmlApplicationContext("/applicationContext-ioc.xml");
IItemsService itemsService= classPathXmlApplicationContext.getBean("itemsService",IItemsService.class);
System.out.println(itemsService.selectItems());
}
三 给mapper接口创建代理，替代原dao层的功能
1.在applicationContext-ioc.xml文件中 添加
<!-- 配置映射文件的扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.test.mapper"/>
</bean>
-
修改service代码
将之前的
@Autowired
private IItemsDao itemsDao;
修改为
@Autowired
private ItemsMapper itemsMapper;
完整代码如下
package com.test.service.impl;
import com.test.dao.IItemsDao;
import com.test.mapper.ItemsMapper;
import com.test.pojo.Items;
import com.test.service.IItemsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class ItemsService implements IItemsService {
@Autowired
private ItemsMapper itemsMapper;
public List<Items> selectItems()
{
return itemsMapper.selectItems();
}
}
- 原来的dao层可以删除
- 测试代码不变
四.在spring中引入springmvc
1.导入jar包
<!-- 导入SpringMvc 需要的jar包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.18.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.3.18.RELEASE</version>
</dependency>
2.创建springmvc.xml的配置文件
<?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"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 1. 扫描包 控制层 -->
<context:component-scan base-package="com.test.action" />
<!-- 2. 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 3 开启注解-->
<mvc:annotation-driven></mvc:annotation-driven>
</beans>
3. 在web.xml 添加 DispatcherServlet
<!-- 配置 DispatcherServlet -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
4.在web.xml 添加 spring容器的加载监听器
让springmvc中的DispatcherServlet帮我们启动spring的相关配置文件
配置在DispatcherServlet的前面
<!-- 配置spring...xml文件的路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-ioc.xml</param-value>
</context-param>
<!-- 配置context 加载的监听器 -->
<!-- 加载spring 的容器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
5.创建控制层的类和方法 并加入注解
package com.test.action;
import com.test.pojo.Items;
import com.test.service.IItemsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/items")
public class ItemsAction {
@Autowired
private IItemsService itemsService;
public IItemsService getItemsService() {
return itemsService;
}
public void setItemsService(IItemsService itemsService) {
this.itemsService = itemsService;
}
@RequestMapping("/selectItemsList")
public ModelAndView selectItemsList()
{
//调用service的查询方法 返回一个list
List<Items> itemsList= itemsService.selectItems();
//组装ModelAndView 对象
ModelAndView modelAndView=new ModelAndView();
modelAndView.addObject("itemsList",itemsList);
modelAndView.setViewName("showItems");
//将数据存入 request，并转发到 WEB-INF/showItems.jsp页面
return modelAndView;
}
}
6.创建视图页面
根据之前配置的试图解析器中的前缀，需要将jsp文件创建在 WEB-INF文件夹下
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%--
Created by IntelliJ IDEA.
User: Administrator
Date: 2019\6\26 0026
Time: 10:36
To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<c:forEach var="items" items="${itemsList}" >
${items.name}<br/>
</c:forEach>
</body>
</html>
7.执行
http://localhost:8080/testssm/items/selectItemsList
五.相关配置文件附录:
