Idea创建spring+springMVC+mybatis+jsp项目

1.创建maven项目。

选择本地安装的maven和对应的setting.xml。

如果没有配置archetypeCatalog这个参数，在maven生成骨架的时候将会非常慢，有时候直接卡住。archetypeCatalog表示插件使用的archetype元数据，不加这个参数时默认为remote，local，即中央仓库archetype元数据，由于中央仓库的archetype太多了所以导致很慢，指定internal来表示仅使用内部元数据。

2.pom.xml添加依赖

    <dependency>
          <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc
      </artifactId>
      <version>5.0.8.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>5.0.8.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.aspectj</groupId>
      <artifactId>aspectjrt</artifactId>
      <version>1.8.12</version>
    </dependency>
    <dependency>
      <groupId>org.aspectj</groupId>
      <artifactId>aspectjweaver</artifactId>
      <version>1.8.12</version>
    </dependency>
    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.27</version>
    </dependency>
    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>druid</artifactId>
      <version>1.1.10</version>
    </dependency>

3.在main文件夹下创建java、resources文件夹

将java文件夹设置为Source Root

将resources文件夹设置为Resources Root

4.在java下创建项目的结构

5.在resources文件夹下创建applicationContext.xml文件：配置包扫描

<?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 http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.cxb.ssm" use-default-filters="true">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:exclude-filter>
    </context:component-scan>

</beans>

同上创建spring-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.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <context:component-scan base-package="com.cxb.ssm" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:include-filter>
    </context:component-scan>

    <mvc:annotation-driven/>

</beans>

接下来配置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">
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <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:spring-servlet.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

6.创建HelloService，返回字符串，暂未连接数据库。

package com.cxb.ssm.service;

import org.springframework.stereotype.Service;

@Service
public class HelloService {

    public String hello(){
        return "hello springMvc!";
    }
}

7.创建HelloController

package com.cxb.ssm.controller;

import com.cxb.ssm.service.HelloService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class HelloController {

    @Autowired
    HelloService helloService;

    @RequestMapping("/hello")
    public String hello(){
        return helloService.hello();
    }
}

8.配置tomcat项目

9.配置完成，启动项目

启动成功会有下面的页面出现，这就是index.jsp

测试访问helloController   http://localhost:8081/ssm_war/hello

自此spring、springmvc配置完成。

**********************************************************************************************************************************

整合jsp

**********************************************************************************************************************************

10.在pom.xml中导入jsp依赖

    <!--jsp-->
    <dependency>

    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

13.创建IndexController

package com.cxb.ssm.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {

    @RequestMapping("/helloJsp")
    public  String index(){
        return "hello";
    }
}

14.在jsp文件夹下创建hello.jsp

<html>
<body>
<h2>Hello JSP!</h2>
</body>
</html>

15.重启项目访问

http://localhost:8081/ssm_war/helloJsp

JSP整合成功！

*****************************************************************************************************

整合Mybatis

19.创建ssm数据库

-- --------------------------------------------------------
-- 主机:                           127.0.0.1
-- 服务器版本:                        5.6.40 - MySQL Community Server (GPL)
-- 服务器操作系统:                      Win64
-- HeidiSQL 版本:                  8.2.0.4675
-- --------------------------------------------------------

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET NAMES utf8 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;

-- 导出 ssm 的数据库结构
CREATE DATABASE IF NOT EXISTS `ssm` /*!40100 DEFAULT CHARACTER SET utf8 */;
USE `ssm`;


-- 导出  表 ssm.book 结构
CREATE TABLE IF NOT EXISTS `book` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '图书ID',
  `name` varchar(100) NOT NULL COMMENT '图书名称',
  `stock` int(11) NOT NULL COMMENT '馆藏数量',
  `remark` varchar(50) DEFAULT NULL COMMENT '备注',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1004 DEFAULT CHARSET=utf8 COMMENT='图书表';

-- 正在导出表  ssm.book 的数据：~1 rows (大约)
DELETE FROM `book`;
/*!40000 ALTER TABLE `book` DISABLE KEYS */;
INSERT INTO `book` (`id`, `name`, `stock`, `remark`) VALUES
	(1001, '数据库设计', 100, '人民出版社'),
	(1002, '面向对象程序设计', 260, '重庆出版社'),
	(1003, '高并发的处理', 500, '忠县出版社');
/*!40000 ALTER TABLE `book` ENABLE KEYS */;
/*!40101 SET SQL_MODE=IFNULL(@OLD_SQL_MODE, '') */;
/*!40014 SET FOREIGN_KEY_CHECKS=IF(@OLD_FOREIGN_KEY_CHECKS IS NULL, 1, @OLD_FOREIGN_KEY_CHECKS) */;
/*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */;

20.创建Book相关的，实现数据库的查询与页面数据的渲染

Book：

package com.cxb.ssm.vo;

public class Book {

    private  Integer id;
    private  String name;
    private Integer stock;
    private String remark;

    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 getStock() {
        return stock;
    }

    public void setStock(Integer stock) {
        this.stock = stock;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }

    @Override
    public String toString() {
        return "Book{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", stock=" + stock +
                ", remark='" + remark + '\'' +
                '}';
    }
}

BookMapper：

package com.cxb.ssm.dao;

import com.cxb.ssm.vo.Book;

import java.util.List;

public interface BookMapper {

    List<Book> getAllBook();
}

BookService：

package com.cxb.ssm.service;

import com.cxb.ssm.vo.Book;

import java.util.List;

public interface BookService {
    List<Book> getAllBook();
}

BookServiceImpl：

package com.cxb.ssm.service.impl;

import com.cxb.ssm.dao.BookMapper;
import com.cxb.ssm.service.BookService;
import com.cxb.ssm.vo.Book;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class BookServiceImpl implements BookService {

    @Autowired
    private BookMapper bookMapper;

    @Override
    public List<Book> getAllBook() {
        return bookMapper.getAllBook();
    }
}

BookController：

package com.cxb.ssm.controller;

import com.cxb.ssm.service.BookService;
import com.cxb.ssm.vo.Book;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
public class BookController {

    @Autowired
    private BookService bookService;

    @RequestMapping("/getAllBook")
    public String getAllBook(Model mod){
        List<Book> books = bookService.getAllBook();
        mod.addAttribute("books",books);
        return "book";
    }
}

bookMapping.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="com.cxb.ssm.dao.BookMapper">
    <select id="getAllBook" resultType="com.cxb.ssm.vo.Book">
        select * from book;
    </select>
</mapper>

book.jsp：

<%@ 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"%>

<html>
<head>
    <title>Book List</title>
</head>
<body>
<table style="margin-top:5px;">
    <thead>
    <tr>
        <th class="center">库存</th>
        <th class="center">名称</th>
        <th class="center">备注</th>
    </tr>
    </thead>
    <tbody>
    <!-- 开始循环 -->
    <c:forEach items="${books}" var="book" varStatus="vs">
        <tr>
            <td class='center' style="width: 30px;">${book.stock}</td>
            <td class='center'>${book.name}</td>
            <td class='center'>${book.remark}</td>
        </tr>
    </c:forEach>
    </tbody>
</table>


</body>
</html>

21.启动项目，测试

http://localhost:8081/ssm_war/getAllBook

数据查询成功，自此spring、springmvc、mybatis、jsp整合完成！
