基于ssm框架的个人博客（2）--基于maven的ssm框架的整合

        在基于ssm框架的个人博客（1）中，数据库相关的已经初步实现了（后续或许需要改进，但是实际项目的数据库一般都预先设计好了，不能随意改动吧）。在这个基础上，我们来整合一下ssm框架，其中，我使用Maven来构建并管理项目。

         Maven的好处很多，暂时我深有体会的是：maven管理jar包的方便，maven的一些命令是的项目管理方便，maven的插件（java编译插件、tomcat插件）使得我们项目配置变得简单。如果是大型项目，分布式架构，一些子模块的jar包管理变得复杂，但是如果是maven工程的话，依赖的继承使得jar包管理配置变得清晰，版本也能进行比较好的控制。

       Maven好处太多啦！细节的话，学了，用了才知道！现在说说ssm框架（springMVC+mybatis+spring），数据库访问框架使用的是mybatis，web层、service、dao层对象的创建与管理，交给spring负责，控制层使用springMVC。

       具体每个框架的使用，我不想过多介绍，能读这文章的应该是熟悉这些框架的，不熟悉也没事，可以了解到整个小型web项目的开发过程，这也是收获嘛！

项目结构：

下面直接上整合代码：

接着，数据库的操作，我是用mybatis的逆向工程来生成，如何生成，生成的内容，不多解释，直接看图：

理论上，现在ssm整合已经结束了，我们先来测试一下，没跑通，一切都是瞎搞！

现在我直接贴上我的测试代码：

package com.lailai.controller;

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


import com.lailai.service.findBlogService;
import com.lailai.service.impl.findBlogServiceImpl;


@Controller
public class findBlogController {
@Autowired
private findBlogService findBlogService;
@RequestMapping("aa")
public String ssd(){
findBlogService.findBlogByid(1);
return "success";
}
}

package com.lailai.service;

public interface findBlogService {
public void findBlogByid(int i);
}

package com.lailai.service.impl;

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


import com.lailai.entity.TBlogWithBLOBs;
import com.lailai.mapper.TBlogMapper;
import com.lailai.service.findBlogService;
@Service
public class findBlogServiceImpl implements findBlogService {
@Autowired
private TBlogMapper tBlogMapper;

@Override
public void findBlogByid(int i) {
System.out.println(tBlogMapper);
TBlogWithBLOBs selectByPrimaryKey = tBlogMapper.selectByPrimaryKey(new Integer(i));
System.out.println(selectByPrimaryKey.getContent());
}
}

测试的数据库内容：

浏览器访问地址：http://127.0.0.1:8080/mybolog/aa

跳转到success.jsp页面，打印success        （验证了springMVC的流程控制）

控制台输出：

org.apache.ibatis.binding.MapperProxy@4da27172     （验证spring的ioc，依赖注入）
好文章                    （验证了mybatis逆向工程生成的文件的可操作性）

。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

        综合起来，我们的ssm框架算是整合成功了，如果你还在为不能配好各种配置文件发愁，我觉得你应该先熟悉三个框架的独自配置，部分整合，最后再搞ssm整合。我觉得只要懂得配置文件的配置原理，不需要强记配置信息，不清楚的部分可以查阅资料。

        接下来恐怕就是要搞搞前端页面咯！这是我比较薄弱的一块，但是不会前端的后端程序员，可能会很麻烦哦！由于此博客系统的重点在使用，所以我不考虑页面的美观！最终我决定使用easyUI。

希望该文章帮助到了读者，希望关注我博客的朋友都有所收获，文章还在继续编辑ing......
