基于ssm架構的個人部落格（2）--基于maven的ssm架構的整合

        在基于ssm架構的個人部落格（1）中，資料庫相關的已經初步實作了（後續或許需要改進，但是實際項目的資料庫一般都預先設計好了，不能随意改動吧）。在這個基礎上，我們來整合一下ssm架構，其中，我使用Maven來建構并管理項目。

         Maven的好處很多，暫時我深有體會的是：maven管理jar包的友善，maven的一些指令是的項目管理友善，maven的插件（java編譯插件、tomcat插件）使得我們項目配置變得簡單。如果是大型項目，分布式架構，一些子子產品的jar包管理變得複雜，但是如果是maven工程的話，依賴的繼承使得jar包管理配置變得清晰，版本也能進行比較好的控制。

       Maven好處太多啦！細節的話，學了，用了才知道！現在說說ssm架構（springMVC+mybatis+spring），資料庫通路架構使用的是mybatis，web層、service、dao層對象的建立與管理，交給spring負責，控制層使用springMVC。

       具體每個架構的使用，我不想過多介紹，能讀這文章的應該是熟悉這些架構的，不熟悉也沒事，可以了解到整個小型web項目的開發過程，這也是收獲嘛！

接着，資料庫的操作，我是用mybatis的逆向工程來生成，如何生成，生成的内容，不多解釋，直接看圖：

基于ssm架構的個人部落格（2）--基于maven的ssm架構的整合

理論上，現在ssm整合已經結束了，我們先來測試一下，沒跑通，一切都是瞎搞！

現在我直接貼上我的測試代碼：

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());

}

}

測試的資料庫内容：

基于ssm架構的個人部落格（2）--基于maven的ssm架構的整合

浏覽器通路位址：http://127.0.0.1:8080/mybolog/aa

跳轉到success.jsp頁面，列印success        （驗證了springMVC的流程控制）

控制台輸出：

[email protected]     （驗證spring的ioc，依賴注入）

好文章                    （驗證了mybatis逆向工程生成的檔案的可操作性）

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

        綜合起來，我們的ssm架構算是整合成功了，如果你還在為不能配好各種配置檔案發愁，我覺得你應該先熟悉三個架構的獨自配置，部分整合，最後再搞ssm整合。我覺得隻要懂得配置檔案的配置原理，不需要強記配置資訊，不清楚的部分可以查閱資料。

        接下來恐怕就是要搞搞前端頁面咯！這是我比較薄弱的一塊，但是不會前端的後端程式員，可能會很麻煩哦！由于此部落格系統的重點在使用，是以我不考慮頁面的美觀！最終我決定使用easyUI。

希望該文章幫助到了讀者，希望關注我部落格的朋友都有所收獲，文章還在繼續編輯ing......
