标签：框架 int 书籍 list public SSM Book 整合 book
前言
刚学完SSM框架的时候，感觉整合还是很简单的，但是，等过了一段时间之后，再回过头来用SSM框架写项目的时候，感觉既熟悉又陌生，所以，本人就复习一下，并且写这一篇博客记录相关知识。
1.创建数据库
CREATE DATABASE `ssmbuild`;
USE `ssmbuild`;
DROP TABLE IF EXISTS `books`;
CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8
INSERT INTO books(bookID,bookName,bookCounts,detail)VALUES
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
2.创建项目
1）首先创建一个maven项目，添加web支持，在pom.xml中导入依赖
<dependencies>
<!--Junit-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<!--数据库驱动-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.47</version>
</dependency>
<!-- 数据库连接池 -->
<dependency>
<groupId>com.mchange</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.5.2</version>
</dependency>
<!--Servlet - JSP -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<!--Mybatis-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.5.2</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>2.0.2</version>
</dependency>
<!--Spring-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.1.9.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.1.9.RELEASE</version>
</dependency>
</dependencies>
2）创建相关包
ewen.dao
ewen.pojo
ewen.service
ewen.controller
在resource目录下，创建mapper、spring文件夹
3.mybatis 相关配置
1）创建mybatis-connfig.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>
</configuration>
2）创建jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456
3）创建实体类
private int bookID;
private String bookName;
private int bookCounts;
private String detail;
//get 、set 方法，构造函数
4）在dao包中创建BookMapper接口
public interface BookMapper {
public int insert(Book book);
public int delete(Book book);
public int update(Book book);
public Book queryByBookId(int id);
public List<Book> queryAll();
public Book queryByBookName(String bookName);
}
5）在mapper文件加下创建BookMapper.xml,编写SQL语句
<?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="ewen.dao.BookMapper">
<!--添加书-->
<select id="insert" resultType="int" parameterType="Book">
insert into books
(bookName,bookCounts,detail)
values
(#{bookName},#{bookCounts},#{detail});
</select>
<!--删除书-->
<delete id="delete" parameterType="int">
delete from books where bookID = #{bookID}
</delete>
<!--修改书-->
<update id="update" parameterType="Book">
update books set bookName = #{bookName}, bookCounts = #{bookCounts}, detail = #{detail}
where bookID = #{bookID}
</update>
<!--通过id查询书-->
<select id="queryByBookID" parameterType="int" resultType="Book">
select * from books where bookID = #{bookID}
</select>
<!--查询所有书-->
<select id="queryAll" resultType="Book">
select * from books
</select>
<!--根据书名进行查询-->
<select id="queryByBookName" resultType="Book" parameterType="String">
select * from books where bookName = #{bookName}
</select>
</mapper>
6）编写service层的接口和实现类
BookService接口：
public interface BookService {
public int insert(Book book);
public int delete(Book book);
public int update(Book book);
public Book queryByBookId(int id);
public List<Book> queryAll();
}
实现类：
public class BookServiceImpl implements BookService {
@Autowired
private BookMapper bookMapper;
public int insert(Book book) {
return bookMapper.insert(book);
}
public int delete(Book book) {
return bookMapper.delete(book);
}
public int update(Book book) {
return bookMapper.update(book);
}
public Book queryByBookId(int id) {
return bookMapper.queryByBookId(id);
}
public List<Book> queryAll() {
return bookMapper.queryAll();
}
}
4.spring整合mybatis
在spring文件夹下创建spring-dao.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.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<!--加载数据库连接的配置文件-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--配置c3p0连接池-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<!--配置连接池属性-->
<property name="driverClass" value="${jdbc.driver}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<!-- c3p0连接池的私有属性 -->
<property name="maxPoolSize" value="30" />
<property name="minPoolSize" value="10" />
<!-- 关闭连接后不自动commit -->
<property name="autoCommitOnClose" value="false" />
<!-- 获取连接超时时间 -->
<property name="checkoutTimeout" value="10000" />
<!-- 当获取连接失败重试次数 -->
<property name="acquireRetryAttempts" value="2" />
</bean>
<!--配置sqlSessionFactory对象-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--注入连接池-->
<property name="dataSource" ref="dataSource"/>
<!--配置mybatis核心配置文件-->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<!--开启别名-->
<property name="typeAliasesPackage" value="ewen.pojo"/>
<!-- 扫描sql配置文件:mapper需要的xml文件 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean>
<!--用扫描包的形式配置mapper，动态实现Dao接口，注入到spring容器中 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--注入sqlSessionFactory对象-->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!--给出需要扫描的dao接口-->
<property name="basePackage" value="ewen.dao"/>
</bean>
</beans>
5.Spring整合service层
在spring文件夹下创建spring-service.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.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<!--配置service扫描，扫描service包下所有使用注解的类型-->
<context:component-scan base-package="ewen.service"/>
</beans>
6.配置springMVC
1）web.xml
<?xml version="1.0" encoding="UTF-8"?>
<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_4_0.xsd"
version="4.0">
<!--配置核心控制器-->
<servlet>
<servlet-name>ssm</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--加载总的核心配置文件-->
<init-param>
<param-name>ContextConfigLocation</param-name>
<param-value>classpath:spring/spring-*.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ssm</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--解决乱码问题-->
<filter>
<filter-name>encodingFilter</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>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
2）Spring-mvc.xml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-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!--配置包扫描器-->
<context:component-scan base-package="ewen.controller"/>
<!--配置springmvc的注解驱动-->
<mvc:annotation-driven/>
<!--配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
到这里框架就整合好了,整个项目的架构如图：
下面写一个简单的增删改查操作
前端页面简单使用bootstrap
1.书籍列表页面allBook.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>书籍列表</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- 引入 Bootstrap -->
<link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">
<div class="row clearfix">
<div class="col-md-12 column">
<div class="page-header">

<button type="submit" class="btn btn-primary">查询</button>
<span style="color: red">${error}</span>
</form>
</div>
</div>
<div class="row clearfix">
<div class="col-md-12 column">
<table class="table table-hover table-striped">
<thead>
<tr>
<th>书籍编号</th>
<th>书籍名字</th>
<th>书籍数量</th>
<th>书籍详情</th>
<th>操作</th>
</tr>
</thead>
<tbody>
<tbody>
<c:forEach var="book" items="${list}">
<tr>
<td>${book.getBookID()}</td>
<td>${book.getBookName()}</td>
<td>${book.getBookCounts()}</td>
<td>${book.getDetail()}</td>
<td>
<a class="btn btn-default" href="${pageContext.request.contextPath}/book/toUpdate?id=${book.getBookID()}">更改</a>
|
<a class="btn btn-default" href="${pageContext.request.contextPath}/book/delete/${book.getBookID()}">删除</a>
</td>
</tr>
</c:forEach>
</tbody>
</table>
</div>
</div>
</div>
</body>
2.插入书籍页面

</div>
<button type="submit" class="btn btn-default">更改</button>
</form>
</div>
</div>
</div>
</body>
4.BookController
@Controller
@RequestMapping("/book")
public class BookController {
@Resource
private BookService bookService;
//查询所有书籍
@RequestMapping("/list")
public String list(Model model){
List<Book> list = bookService.queryAll();
model.addAttribute("list",list);
return "allBook";
}
//到添加页面
@RequestMapping("/toInsert")
public String toInsert(){
return "insert";
}
//添加书籍
@RequestMapping("/insert")
public String insert(Book book){
bookService.insert(book);
return "redirect: /book/list";
}
//到更新页面
@RequestMapping("/toUpdate")
public String toUpdate(Model model, int id){
Book book = bookService.queryByBookId(id);
model.addAttribute("book",book);
return "update";
}
@RequestMapping("/updateBook")
public String updateBook(Book book){
bookService.update(book);
return "redirect:/book/list";
}
@RequestMapping("/delete/{bookID}")
public String delete(@PathVariable("bookID") int id){
Book book = bookService.queryByBookId(id);
bookService.delete(book);
return "redirect:/book/list";
}
@RequestMapping("/queryByBookName")
public String queryByBookName(String bookName,Model model){
Book book = bookService.queryByBookName(bookName);
System.out.println(book);
List<Book> list = new ArrayList<Book>();
list.add(book);
if(book == null){
list = bookService.queryAll();
model.addAttribute("error","数据库无此书");
}
model.addAttribute("list", list);
return "allBook";
}
}
基于这个，还可以添加更多功能，有时间还会持续更新的。
