JAVA:ssm框架搭建

文章来源:http://www.cnblogs.com/hello-tl/p/8328071.html

环境简介 : jdk1.7.0_25/jdk1.8.0_31  tomcat-7.0.81  maven-3.3.9  MyEclipse-2013  spring-4.0.2 springMvc-4.0.2 mybatis-3.2.8

SSM(Spring+SpringMVC+MyBatis)框架集由Spring、SpringMVC、MyBatis三个开源框架整合而成,常作为数据源较简单的web项目的框架。

其中spring是一个轻量级的控制反转(IoC)和面向切面(AOP)的容器框架。
SpringMVC分离了控制器、模型对象、分派器以及处理程序对象的角色,这种分离让它们更容易进行定制。
MyBatis是一个支持普通SQL查询,存储过程和高级映射的优秀持久层框架。
 
0、创建一个maven项目
  1)图解
    右键->New->Project
    JAVA:ssm框架搭建
 
    出现以下界 选择 Maven Project  ->  Next

    JAVA:ssm框架搭建

    

    选择项目路径 -> Next

    JAVA:ssm框架搭建

    

    选择项目类型 webapp

    JAVA:ssm框架搭建

    

    填写 Group Id / Artifact Id -> Fubush

    JAVA:ssm框架搭建

    

    之后会出现一下

    JAVA:ssm框架搭建

    项目右键单击 properties 设置项目字符编码

    JAVA:ssm框架搭建

    

    设置包 完事之后  maven 项目就创建完毕

    JAVA:ssm框架搭建

 1、ssm jar包下载

  1) 下载ssm框架所需jar包

    pom.xml

  2) 创建几个必要的包

    JAVA:ssm框架搭建

     包的作用

dao 数据访问层(接口) 与数据打交道,可以是数据库操作,也可以是文件读写操作,甚至是redis缓存操作,总之与数据操作有关的都放在这里,也有人叫做dal或者数据持久层都差不多意思。为什么没有daoImpl,因为我们用的是mybatis,所以可以直接在配置文件中实现接口的每个方法。
dto数据传输层 刚学框架的人可能不明白这个有什么用,其实就是用于service层与web层之间传输,为什么不直接用entity(pojo)?其实在实际开发中发现,很多时间一个entity并不能满足我们的业务需求,可能呈现给用户的信息十分之多,这时候就有了dto,也相当于vo,记住一定不要把这个混杂在entity里面,答应我好吗?
service业务逻辑接口 写我们的业务逻辑,也有人叫bll,在设计业务接口时候应该站在“使用者”的角度。额,不要问我为什么这里没显示!IDE调皮我也拿它没办法~
controller控制器 springmvc就是在这里发挥作用的,一般人叫做controller控制器,相当于struts中的action。
mapper实体类 一般与数据库的表相对应,封装dao层取出来的数据为一个对象,也就是我们常说的pojo,一般只在dao层与service层之间传输。

2、配置ssm相关的xml文件

  xml文件注释齐全我这里就不解释  配置文件都在 resources 文件下

    文件都有:
       applicationContext.xml

      spring-dao.xml

      spring-db.xml

      spring-mvc.xml

      spring-tx.xml

      jdbc.properties

      log4j.properties

  最后还需要配置一下web.xml  src/main/webapp/WEB-INF/web.xml

  web.xml

  我们一共配置了8个配置文件我们来看一下结构图

    JAVA:ssm框架搭建

3、测试一下是否完成ssm框架的搭建 我们在网页上打印hello world

  com.helloTl.controller/MainController.java

package com.helloTl.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping; @Controller
@RequestMapping("/main")
public class MainController{ @RequestMapping(value = "/index")
public String index(){
return "main/index";
}
}

  src/main/webapp/WEB-INF/jsp/main/index.jsp

<html>
<body>
<h2>Hello World! hello-tl.com</h2>
</body>
</html>

  访问浏览器 http://localhost:8080/hello-tl.com/main/index

JAVA:ssm框架搭建

  出现以上情况表示ssm搭建成功
