eclipse搭建SSM框架

62 阅读 0 评论
我是靠谱客的博主 舒心歌曲，最近开发中收集的这篇文章主要介绍eclipse搭建SSM框架，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

环境：eclipse 、Tomcat8.5、Maven3.6

1.新建maven项目

2.项目建立后上面有红叉

解决办法：

右键项目-->build path-- >configure and build-->在libraries那一栏下，选择ADD Libarry-->选择server Runtime-->选择tomcat然后finish-->apply然后关闭

3.pom.xml文件添加依赖

4.SSM配置：4个配置文件

web.xml配置

        将IOC容器对象存放到application域.
        ApplicationContext ioc = WebApplicationContextUtils.getWebApplicationContext(application);


        ServletContextListener监听器接口:
            监听ServletContext创建和销毁.
                如果监听到ServletContext创建(服务器启动),就会创建IOC容器(XmlWebApplicationContext).
                如果监听到ServletContext销毁(服务器停止,或卸载项目),就会销毁IOC容器.

spring-config.xml配置

springmvc-config.xml配置

	<mvc:resources mapping="/gif/**" location="/gif/" />
	<mvc:resources mapping="/jquery/**" location="/jquery/" />
</beans>

mybatis-config.xml配置

<?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>
	<!-- 原先的配置基本都被spring接管 -->
	<!-- 别名配置 把entity包中简单类起个别名（如User类的别名就是user） -->
	<typeAliases>
		<package name="entity" />
	</typeAliases>
</configuration>

5.将项目添加到tomcat运行没报错就是成功了

SSM例子

先看一下文件的目录

 

新建jsp文件

index.jsp实现跳转功能

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<a href="${pageContext.request.contextPath}/index.htm" }>index</a><br>
<a href="${pageContext.request.contextPath}/test.htm" }>test</a>
</body>
</html>

TestController控制层

package controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import service.TestService;

@Controller
public class TestController {
	@Autowired
	private TestService testservice;
	
	@RequestMapping("/test")
	public String testfun() {
		System.out.println("测试控制器TestController");
		testservice.insert();
		System.out.println("测试控制器TestController结束");
		return "account/index";//跳转到/WEB-INF/views/account下的index.jsp
	}
}

TestService和TestServiceImpl 业务层

package service;

public interface TestService {
	public void insert();
}

package service.impl;

import java.util.HashMap;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import dao.TestDao;
import service.TestService;

@Service
public class TestServiceImpl implements TestService {

	@Autowired
	private TestDao testdao;
	
	@Override
	public void insert() {
		// TODO Auto-generated method stub
		System.out.println("insert()方法");
		Map map=new HashMap();
		map.put("id", "1");
		map.put("username", "fan");
		map.put("password", "123");
		testdao.insertDao(map);
	}

}

DAO层

package dao;

import java.util.Map;

public interface TestDao {
	public void insertDao(Map map);
}

UserMapper.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="dao.TestDao">
    <insert id="insertDao">
        insert into user (
            id,username,password
        ) values (
            #{id},#{username},#{password}
        )
    </insert>
</mapper>

然后运行，可以在事先创建的简单数据库表里看见插入了我们在service层写进去的字段
