使用IDEA搭建ssm框架

工具：IDEA 2018.1

jdk版本：jdk1.8.0_171

Maven版本：apache-maven-3.5.3

Tomcat版本：apache-tomcat-8.5.30

新建maven项目

项目基本展示

编写pom.xml文件,导入相关jar包

新建各种Package包，其中有：

在java文件下新建以下文件：

com.flyme.controller

com.flyme.mapper

com.flyme.po

com.flyme.service

com.flyme.service.impl

添加db.properties数据库配置、以及日志log4j.properties配置文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/examination_system
jdbc.username=root
jdbc.password=root

log4j.properties

添加Spring配置文件

在recources文件下新建spring文件夹，并且在其下新建下文件

添加springmvc配置文件

在resources/spring文件下，新建springmvc.xml文件

springmvc.xml

    <!--加载静态资源-->

    <!--开启注解注解驱动-->

    <!--视图解析器-->

        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

重新编写web.xml文件

web.xml

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--contextConfigLocation配置SpringMVC加载的配置文件（配置处理器，映射器等等）

        <init-param>

SSM框架就此已经搭建完成，下面进行测试

mybatis进行逆向工程

生产po、mapper相关文件，看图。

如何通过mybatis逆向工程生成，见链接。后续更新

测试类

mybatis框架测试

在src/test/java下面进行创建包com.flyme.service，在此下面进行创建CourseServiceImplTest测试类，以用来测试mybatis框架是否搭建成功。

CourseServiceImplTest.java

package com.flyme.service;

import com.flyme.po.Course;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;


public class CourseServiceImplTest {


    private ApplicationContext applicationContext;

    @Before
    public void setUp() throws Exception {
        applicationContext = new ClassPathXmlApplicationContext(new String[]{"spring/applicationContext-dao.xml",
                "spring/applicationContext-service.xml"});
    }

    @Test
    public void findById() throws Exception {

        CourseService courseService = (CourseService) applicationContext.getBean("courseServiceImpl");
        Course course = courseService.findById(1);
        System.out.println(course.toString());
    }

}

运行findById()方法，出现以下图，证明搭建成功

SpringMVC框架测试

AdminController.java

在src/main/java，com.flyme.controller包下面创建AdminController.java，以用来测SpringMVC框架是否搭建成功。

package com.flyme.controller;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@WebServlet("/myController")
public class AdminController extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doPost(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String name = req.getParameter("name");
        req.setAttribute("name", name);
        System.out.println(name);
        req.getRequestDispatcher("index.jsp").forward(req, resp);
    }
}

idex.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<form action="myController" method="post">
    <input name="name">
    return:${name}
    <input value="提交" type="submit">
</form>
</body>
</html>

运行项目

配置Tomcat

最后选择OK，即可。

浏览器输入 http://localhost:8010/ （因为笔者改动了端口号，灵活应用）

输入：“我是”

结果：

配置成功
