SSM整合最新版,spring4.2,springmvc4.2,mybatis3.2整合
**目前网站开发常使用的三层框架体系结构:
ssh和ssm即(spring,struts2,hibernate)和(spring,springmvc,mybatis),但是目前使用较多的是ssm,可能是由于struts2的严重漏洞导致大家对于ssh框架失去了信心,
Struts2 官方对于安全问题的处理让人担忧，竟然会直接演示攻击方法，多少个站长彻夜将自己的网站升级，然而 Hibernate 我估计是很多掌握不了其内部的逻辑，瞬时态，持久态，托管态，延时加载，事务边界，在加上对于SQL调优的不利因素，所以也渐渐的不流行
而spring自家的springmvc无需第三方类库支持,可以实现无缝连接,配合mybatis完全可以满足大部分企业对于网站开发的要求,而且性能也很不错,学习成本也较低
,但是两者都有其是使用场景,并不能说谁取代谁,就目前来看,ssm略占上风,但是ssh在校园开发,小型企业开发中使用较多,建议稍微了解一下,会使用就好,ssh和ssm的学习可以参照我的csdn文章学习**
整合第一步导入jar包
jar包包含：c3p0数据库连接池
aop联盟
spring和springmvc
以及mybatis和spring-mybatis整合包
二级缓存包
第二步dao开发:逆向工程自动生成mapper和实体类：
2.1数据库,关系,测试数据,用户自己添加:
2.2,逆向工程的使用教程地址:
http://blog.csdn.net/do_bset_yourself/article/details/51276517
生成结构如下:
第三步service开发,这里只做测试,service没有实际意义:
package com.leige.service;
import com.leige.domain.Student;
public interface StudentService {
//根据id查找学生
public Student selectStudent(Integer id);
}
第四步:spring mvc的controler开发
package com.leige.controler;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.leige.domain.Student;
import com.leige.service.StudentService;
/**
* @author 都市桃源
* springmvc写controler,实现Controler接口
*
*/
@Controller
@RequestMapping("/student")
public class StudentControler implements org.springframework.web.servlet.mvc.Controller{
@Autowired
private StudentService studentService;
@RequestMapping("/search.action")
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
//获取参数值
Integer sid=Integer.valueOf(request.getParameter("sid"));
//调用业务层,查找
Student stu=studentService.selectStudent(sid);
ModelAndView modelAndView=new ModelAndView();
//设置错误信息
if(stu!=null){
modelAndView.addObject("student",stu);
}else{
modelAndView.addObject("msg","查询不到,sorry");
}
//返回消息页面
modelAndView.setViewName("index");
return modelAndView;
}
}
第五步:view开发,制作简单显示
<body>
<h1>
${msg}
h1>
<p style="color: red;">姓名:${student.name}p>
<p style="color: red;">sid:${student.sid}p>
<p style="color: red;">age:${student.age}p>
body>第六步,各个层次整合开发,配置文件处理
**配置文件在项目路径下新建一个sourcefolder,也是在classpath下,里面放置各种配置文件:
如下:**
6.1.web.xml中配置spring的监听器,加载spring配置文件,配置springmvc的前端控制器,处理用户请求
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

6.2.springmvc配置,详细解释都在配置文件中:springmvc.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"/>
<property name="suffix" value=".jsp" >property>
bean>
beans>**6.3spring配置:这里建议将service,dao,transaction的配置分开,这样可以增加程序的可读性,
建议不要使用include,避免后期维护配置文件麻烦**
6.3.1:spring配置文件dao配置:applicationContext-dao.xml:

beans> 第七步:二级缓存配置,注意mybatis的二级缓存使用,需要在mapper.xml文件中指定,如果想要使对象支持磁盘缓存,建议实现序列化接口:
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
<diskStore path="F:\cache"/>
<defaultCache
maxElementsInMemory="3000"
eternal="false"
timeToIdleSeconds="3600"
timeToLiveSeconds="3600"
overflowToDisk="true"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="100"
memoryStoreEvictionPolicy="LRU"
/>
<cache name="userCache"
maxElementsInMemory="3000"
eternal="false"
overflowToDisk="true"
timeToIdleSeconds="3600"
timeToLiveSeconds="3600"
memoryStoreEvictionPolicy="LFU"
/>
ehcache>第八步:测试,根据controler中的注解,得知访问url是http://localhost/SSM/student/search.action?sid=1:
测试结果:
最后再强调一句,这里只是初级的整合,并没用真正的设计业务管理,事务管理仅供初级新手学习,也作为一个整合的初级模板,大家也可以在这个基础上,添加自己想要的业务管理\
