mybatis学习笔记(六) -- maven+spring+mybatis从零开始搭建整合详细过程(下)

springmvc学习笔记(一) -- 从零搭建,基础入门

这一篇,在这些练习的基础上,将它们整合在一起!

搭建步骤如下

一、新建maven项目,配置环境,测试是否配置成功

二、整合spring+mybatis,添加ApplicationContext.xml文件,修改pom.xml,,并连接mysql,测试是否搭建成功

(如果想了解单独的mybatis项目,可参考mybatis学习笔记(一)-- 简单入门(附测试Demo详细过程)

三、整合springmvc,添加springmvc-servlet.xml文件,修改调整,测试是否搭建成功

附:第一,二步详细操作步骤可参考

Apply后,查看项目结构可以看到多了个WebContent

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

3、将WebContent下的两个文件复制到src/main/webapp下,然后将WebContent整个删掉

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

4、修改Deployment Assembly,只留下下面几个

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

新增/src/main/webapp,步骤Add->Floder->src->main->webapp->finish

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

5、测试,在src/main/webapp下,新建一个index.jsp文件

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>hello
</body>
</html>

修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

运行tomcat,访问:http://localhost:8888/SSM01/,页面显示“hello”

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

到此,第一步骤完成!!! 

二、整合Spring+MyBatis

1、修改pom.xml,加载项目需要的jar

pom.xml

2、数据库准备

新建数据表tb_book,添加测试数据

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

3、新建包和类

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

(1)添加实体类Book

package com.lmei.ssm.entity;

public class Book {

    private int id;
private String bookName; public int getId() {
return id;
} public void setId(int id) {
this.id = id;
} public String getBookName() {
return bookName;
} public void setBookName(String bookName) {
this.bookName = bookName;
} @Override
public String toString() {
return this.getId()+"\t"+this.getBookName();
}
}

(2)添加Dao,BookDao

package com.lmei.ssm.dao;

import java.util.List;
import com.lmei.ssm.entity.Book; public interface BookDao { public List<Book> getAllBook();
}

(3)添加service,BookService

package com.lmei.ssm.service;

import java.util.List;
import com.lmei.ssm.entity.Book; public interface BookService { public List<Book> getAllBook();
}

(4)添加impl,BookServiceImpl实现BookService

package com.lmei.ssm.impl;

import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service; import com.lmei.ssm.dao.BookDao;
import com.lmei.ssm.entity.Book;
import com.lmei.ssm.service.BookService; @Service
public class BookServiceImpl implements BookService{
@Resource
BookDao bookDao;
public List<Book> getAllBook() {
return bookDao.getAllBook();
}
}

(5)添加BookMapper

<?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.lmei.ssm.dao.BookDao">
<select id="getAllBook" parameterType="int" resultType="Book">
select * from tb_book
</select>
</mapper>

4、添加ApplicationContext.xm和db.propertiesl文件,并注册映射

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

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" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" 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
http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.3.xsd"> <!-- 引入db.properties属性文件 -->
<context:property-placeholder location="classpath:db.properties" /> <!--定义一个jdbc数据源,创建一个驱动管理数据源的bean -->
<bean id="jdbcDataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean> <!--创建一个sql会话工厂bean,指定数据源 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

</bean> <!--自动扫描映射接口-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 指定sql会话工厂,在上面配置过的 -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
<!-- 指定基础包,即自动扫描com.lmei.ssm.dao这个包下的所有接口类 -->
<property name="basePackage" value="com.lmei.ssm.dao"></property>
</bean> <!-- 创建一个sqlSession对象 -->
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
</bean> <!--自动扫描组件 -->
<context:component-scan base-package="com.lmei.ssm">
<context:exclude-filter type="aspectj" expression="com.lmei.ssm.dao.*"/>
</context:component-scan>
<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
</beans>

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc.username=root
jdbc.password=123456

5、添加测试类

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

TestMyBatisSpring

package com.lmei.ssm.test;

import static org.junit.Assert.assertNotNull;
import java.util.List;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext; import com.lmei.ssm.dao.BookDao;
import com.lmei.ssm.entity.Book; public class TestMyBatisSpring {
@Test
public void test() {
//初始化容器
ApplicationContext ctx=new ClassPathXmlApplicationContext("ApplicationContext.xml");
//获得bean
BookDao bookDao = ctx.getBean(BookDao.class);
//访问数据库
List<Book> books = bookDao.getAllBook();
for (Book book : books) {
System.out.println(book.getBookName());
}
assertNotNull(books);
}
}

Run As->JUnit Test

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

到此,第二步完成Spring+MyBatis+Mysql!!! 

三、整合springmvc

1、修改实体类Book

package com.lmei.ssm.entity;

import java.io.Serializable;

public class Book implements Serializable {
private static final long serialVersionUID = 1L;
private int id;
private String bookName; public int getId() {
return id;
} public void setId(int id) {
this.id = id;
} public String getBookName() {
return bookName;
} public void setBookName(String bookName) {
this.bookName = bookName;
} @Override
public String toString() {
return "id:" + getId() + ",bookName:" + getBookName() ;
} }

2、在WEB-INF下新建一个文件夹view,然后在里面新建hello.jsp文件,用来测试springmvc是否搭建成功

路径webapp/WEB-INF/view/hello.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%-- <%@ page isELIgnored="false" %> --%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<p>${message}</p>
</body>
</html>

3、新建一个controller,HelloWorld.java

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

HelloWorld.java代码:

package com.lmei.ssm.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping; //@Controller是为了让Spring IOC容器初始化时自动扫描到;
//@RequestMapping是为了映射请求路径
@Controller
@RequestMapping("/Hello")
public class HelloWorld {
@RequestMapping("/SayHello")
public String SayHello(Model model) {
model.addAttribute("message", "Hello Spring MVC!");
System.out.println(model.containsAttribute("message")); //是否成功赋值
return "hello";
}
}

4、添加springmvc-servlet.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"
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-4.3.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd"> <!-- 自动扫描包,实现支持注解的IOC -->
<context:component-scan base-package="com.lmei.ssm" /> <!-- Spring MVC不处理静态资源 -->
<mvc:default-servlet-handler /> <!-- 支持mvc注解驱动 -->
<mvc:annotation-driven /> <!-- 视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
id="internalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/view/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean> </beans>

5、修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0"> <welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list> <!-- Spring容器启动监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:ApplicationContext.xml</param-value>
</context-param> <servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<!--Spring mvc配置文件路径 -->
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:springmvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> <!--编码过滤器 -->
<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>

之前在测试过程中,不小心把<url-pattern>/ 写错成 /*,导致springmvc把*.jsp,*.sql,*.txt都当做txt处理,访问页面时,直接在浏览器加载了jsp源码。

导致测试页面hello.jsp中的${message}一直取不到Controller传过来的值。

<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

6、测试,项目右键->Run As->Run On Server->Tomcat...

运行成功后,访问:http://localhost:8888/SSM01/Hello/SayHello

控制台输出:输出true,表示${message}赋值成功

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

浏览器输出:

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

到此,SpringMVC搭建成功 !!!

继续整合!!!

7、在controller包下,新建一个BookController

package com.lmei.ssm.controller;

import java.util.List;

import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.lmei.ssm.entity.Book;
import com.lmei.ssm.service.BookService; @Controller
@RequestMapping("/Book")
public class BookController { @Resource
BookService bookService; @RequestMapping("/getAllBook")
public String getAllBook(Model model) {
List<Book> books = bookService.getAllBook();
for (Book book : books) {
System.out.println(book.getBookName());
} model.addAttribute("books", books);
return "Book/index";
}
}

8、在WEB-INFO/view下新建一个文件夹Book,然后在文件夹内添加index.jsp

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

Book/index.jsp代码:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>图书管理</title>
</head>
<body>
<div>
<h3 class="title"><span>图书管理</span></h3>
<table border="1" width="30%" class="tab">
<tr>
<th>编号</th>
<th>书名</th>
</tr>
<c:forEach var="book" items="${books}">
<tr>
<td>${book.id}</td>
<td>${book.bookName}</td>
</tr>
</c:forEach>
</table>
</div>
</body>
</html>

9、测试

运行服务器,在浏览器访问:http://localhost:8888/SSM01/Book/getAllBook

springmvc学习总结(二) -- maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

到此,完成SpringMVC+Spring+MyBatis的整合!!!
