配合maven项目管理，完成SSM框架的搭建，对开发学习做笔记记录。
接上一篇博客笔记，做完maven的环境搭建和jar包依赖添加后
Spring和Mybatis的整合
配置jdbc.properties:
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://****:3306/demo?characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root
jdbc.initialSize=0
jdbc.maxActive=20
jdbc.maxIdle=20
jdbc.minIdle=1
jdbc.maxWait=60000
jdbc.testOnBorrow=true
jdbc.validationQuery=select 1<?xml version="1.0" encoding="UTF-8"?>

在这里我有一个疑惑,原文博客这里并没有配置事务注解，我测试了向数据库添加数据，也能成功，(我在写Hibernate是需要配置事务注解的)
不知道是不是，service实现类，bean 使用了注解的方式,还是其他什么的
这里我把事务注解加上
spring、mybatis 配置方式 可以看这篇博客：http://blog.csdn.net/qh_java/article/details/51601139

在controller包里添加控制类:
package com.test.demo.controller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import com.test.demo.pojo.User;
import com.test.demo.service.UserService;
@Controller
public class UserController {
@Resource
private UserService userService;
@RequestMapping("/showUser")
public String show(@RequestParam(value="id") Integer id, Model model){
System.out.println("id:"+id);
User user = userService.findUser(id);
model.addAttribute("user",user);
return"showUser";
}
}大致上的项目框架搭建就这样,不是过于详细,是慢慢在开发中去积累学习的过程.
先技术,再思想,实践出真知.
