MAVEN结构下SSH注解映射 JETTY|TOMCAT

相对与mybatis,很多同学会觉得hibernate现在用的少，不好用，其实不然，实习阶段遇到很多都是基于hibernate的项目，对于其优劣性有了基础的认识，
之前忙着没什么时间，当然也是懒啊，这几天正好利用空闲时间查阅参考资料 整理搭建了一套ssh的demo 希望对初入职场的小伙伴们有所帮助
1.相信大家已经搭建好了java的开发环境了，这边不做说明（百度很多教程）
2.这个demo搭建平台为eclipse,工作中用的多，当然其他idea也可参考，下面进入搭建正题：
   首先我们需要new一个基础的maven项目
  




group id 为包名 arifact id 为项目名



搭建之后的基础结构目录如下图所示



此时java resources 下目录结构是不完整的 来 我们对其进行手动添加，右击java resources即可java resources。
对了 添加 java时可能会出现报错（为什么不深究），其实它是存在的，可以先命名为javas,新建后对其改名。



强迫症患者可以调整顺序，哈哈，我也是。



至此，一个项目结构OK了，接下来我们添加必要的文件。
首先是web.xml的配置，相关说明已打注释

<?xml version="1.0" encoding="UTF-8"?>

pom.xml 选用maven的一个好处就是可以自动下载依赖包，如果下载过慢，也可以自己配置国内镜像，例如阿里巴巴的资源库

在resources下我们需要简历如下几个文件



config.properties为数据库配置信息

#mysql
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=true
sessionInfoName=sessionInfo
uploadFieldName=filedata
uploadFileMaxSize=20971520
uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid
uploadDirectory=attached
validationQuery=SELECT 1

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/hibernate?useUnicode=true&characterEncoding=gbk
jdbc.username=root
jdbc.password=root

log4j.properties是日志记录，file会在项目根目录下生成日志文件

log4j.rootLogger=INFO,A1,R

log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.Target=System.out

spring-mvc.xml,很多同学在配置的时候会发现静态资源加载不进去，在此我做了简单测试，古老的方法是控制层采用.do或者.action的后缀方法去识别，未免觉得不好，所以我们去掉后缀之后，必须在xml配置静态资源的加载，否则会被系统过滤。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"

spring.xml

<?xml version="1.0" encoding="UTF-8"?>

">

<!-- 引入属性文件 -->
<context:property-placeholder location="classpath:config.properties" />

<!-- 自动扫描dao和service包(自动注入) -->
<context:component-scan base-package="com.gyj.dao" />
<context:component-scan base-package="com.gyj.service" />

</beans>

然后我们在此目录下书写一些demo程序



User.java

package com.gyj.model;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

}
public void setName(String name){
this.name=name;

public String getPassword() {

public void setPassword(String password) {
this.password = password;
}

}

UserDao.java

package com.gyj.dao;

public void deleteUser(String userId){

}

/**

public User getUser(String userId){

}

UserService.java

package com.gyj.service;

import java.util.List;

import com.gyj.model.User;

public interface UserService {

public List<User> getUserList();

public void deleteUser(String userId);

public void saveOrUpdateUser(User user,String userId);

public User getUser(String userId);

}

UserServiceImpl.java 业务层接口实现

package com.gyj.service.impl;

import java.util.List;

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

import com.gyj.dao.UserDao;
import com.gyj.model.User;

@Override
public void deleteUser(String userId) {

}

@Override
public User getUser(String userId) {

return userDao.getUser(userId);
}

@Override
public void saveOrUpdateUser(User user, String userId) {

userDao.saveOrUpdate(user, userId);
}

}

controller代码

package com.gyj.controller;

import java.util.List;

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

import com.gyj.model.User;
import com.gyj.service.UserService;

@Controller
public class UserController {

@RequestMapping("/getUserList")
public String getUserList(Model model){
List<User> userlist = service.getUserList();
model.addAttribute("userlist", userlist);
return "UserList";
}

/**
* 根据id删除用户
*/
@RequestMapping("/deleteUser")
public String deleteUser(String userId){
service.deleteUser(userId);
return "redirect:/getUserList";
}

/**

@RequestMapping("/addOreditUser")
public String toAddUserPage(String userId,Model model){

}

/**

*/
@RequestMapping("/saveOrupdateUser")
public String saveOrUpdateUser(User user,String userId){
service.saveOrUpdateUser(user,userId);
return "redirect:/getUserList";
}
}

至此，框架已搭建完成，初始jdk可能默认1.5，同学们自行设置







在pom.xml我进行了jetty和tomcat的两中配置

jetty示例访问：



为什么要配置两种访问方式？

Jetty更轻量级。这是相对Tomcat而言的。具体就不阐述了，哈哈，我也是小白。

本文结束，亲测可行，希望对大家的工作学习之路有所帮助。
