Java 本地开发环境搭建


项目搭建采用技术栈为:Spring+Spring MVC+Hibernate+Jsp+Gradle+tomcat+mysql5.6

搭建环境文档目录结构说明:

  1. 使用Intellj Idea 搭建项目过程详解
  2. 项目各配置文件讲解及部署
  3. 各层包功能讲解&项目搭建完毕最终效果演示图
  4. 项目中重要代码讲解
  5. webapp文件夹下分层详解
  6. 配置tomcat 运行环境
    7.福利彩蛋

1. 使用Intellj Idea 搭建项目过程详解


1.1 打开Intellj Idea

Intellj idea 截图

1.2 操纵 Intellj Idea 工具栏 新建项目

操纵idea 工具栏
使用Gradle创建项目
完善项目信息
设置Gradle
确定项目信息
选择New Window
初始化项目结构截图

需要说明的是,最初创建的项目视图是不完整的,包括webapp文件夹下没有web.xml,以及src包下缺少Java文件夹(放置java源代码文件),Resources文件夹(放置项目配置文件)。
我们继续做以下操作,使得项目的结构符合web 应用项目的层级标准。

操纵工具栏为项目添加 web.xml全局配置文件

出现如下视图:

新建 web.xml文件
设置web.xml文件存储位置

接下来:单击main文件夹按照如下操作:


手动创建src中main文件夹下java目录
输入java 文件夹名称

点击ok,再按照上图操作操作一遍,输入文件名为resources
最终的结构图如下图所示:

项目最终结构图

2. 项目各配置文件讲解及部署


完成了项目的初始化结构创建,接下来我们需要来创建配置文件。
首先是resources文件夹下的配置文件
2.1 resources下资源文件截图:(最终配置的结果)

3. 各层包功能讲解&项目搭建完毕最终效果演示图


3.1 项目中各层包功能讲解
项目中Java源代码层级结构如下图所示:

项目中Java源代码层级结构

对于www包中的各分层,我们对照上图重点说明:

controller:用于路由各种HTTP访问,其中可以实现对前台页面参数的对象化绑定,这个功能的实现是依赖于spring mvc中的参数绑定功能,以及返回向前端页面返回数据。也可以实现基于Restful 风格API的编写。
dao:用于实现对数据库的操作,包中的代码继承并实现自common中的dao 层代码,采用的是类的适配器模式实现的,这里的代码值得细细品味,可以说是整个项目的灵魂所在之处,稍后说明。
domain:项目中的所有实体类都存在于这个包中,其中的每个具体实体类与数据库表相对应。
dto:实现了序列化的数据传输层对象,可用于接收前台参数,前台参数被封装成dto 对象传输至后台。同时也负责对从数据库中查询数据的封装。
qo:模糊查询对象所在的包,用于封装QBC动态查询参数。
rowmapper:用于映射jdbcTemplate查询数据库返回对象的数据集,并将数据集依照以此对象为集合的实例进行封装。
schedulejob:定时任务类所在的包,在此包中的类上都要加上@Service注解,因为定时任务注解配置在service-applicationContext.xml中,包扫描组件的规则是只扫描类上有@Service注解的组件类。
service:业务逻辑层,所有的业务逻辑组件Bean都放置在这个保重,其中的类中的业务逻辑方法调用了dao实现类中的方法,并且每个有关于数据库操作的方法上都加上了@Transaction注解,用于实现对数据库操作的事务管理。@Transaction是Spring Framework对AOP 的另一种区别于拦截器的自定义注解实现。

4.项目中重要代码讲解


主要讲解一下Dao层中代码对适配器设计模式的应用:
4.1 首先看下commom层中 BaseDao.java

package com.fxmms.common.dao;

import com.fxmms.common.ro.Dto;
import com.fxmms.common.ro.DtoResultWithPageInfo;
import com.fxmms.common.ro.PageQo;
import org.hibernate.Criteria;
import org.springframework.stereotype.Repository;

import java.io.Serializable;
import java.util.List;
import java.util.Map;

/**
 *
 * @param <T>
 * @usage  数据库公共操作接口
 */
@Repository
public interface BaseDao<T> {

 /**
  *
  * 
  * @param id
  * @usage 根据id获取数据库中唯一纪录,封装成java对象并返回
  * @return T
  */
 public T getById(Serializable id);

 /**
  * 
  * 
  * @param id
  * @usage 根据id懒加载数据库中唯一纪录,封装成java对象并返回
  * @return T
  */
 public T load(Serializable id);

 /**
  * 
  * 
  * @param columnName
  *            
  * @param value
  *
  * @usage 根据列名,以及对应的值获取数据库中惟一纪录,封装成Java对象并返回
  *          
  * @return
  */
 public T getByUniqueKey(String columnName, Object value);

 /**
  * 
  * 
  * @param nameValuePairs
  *        
  * @return T
  */
 public T getUniqueResult(Map<String, Object> nameValuePairs);

 /**
  * 
  * 
  * @param columnName
  *            
  * @param value
  *      
  * @param sort
  *            
  * @param order
  *            asc/desc
  * @return List<T>
  */
 public List<T> getListByColumn(String columnName, Object value,
                                   String sort, String order);

 public List<T> getListByColumn(String columnName, Object value);

 /**
  * ͨ
  * 
  * @param nameValuePairs
  *            
  * @param sort
  *            
  * @param order
  *            asc/desc
  * @return List<T>
  */
 public List<T> getListByColumns(Map<String, Object> nameValuePairs,
                                    String sort, String order);

 public List<T> getListByColumns(Map<String, Object> nameValuePairs);

 /**
  * 
  * 
  * @return List<T>
  */
 public List<T> getAll();

 /**
  * 
  * 
  * @param t
  * @return Serializable id
  */
 public Serializable save(T t);

 /**
  * 
  * 
  * @param t
  */
 public void update(T t);

 /**
  * 
  * 
  * @param t
  */
 public void delete(T t);
 
 /**
  * QBC
  * @return
  */
 public Criteria createCriteria();
 
 /**
  * @param <E>
  * @param <D>
  * @param criteria
  * @param pageNo
  * @param pageSize
  * @param dtoClazz
  * @return
  */
 public <E, D extends Dto> DtoResultWithPageInfo<D> queryPageListByCriteria(
            Criteria criteria, int pageNo, int pageSize, Class<D> dtoClazz);
 

 /**
  * @param <E>
  * @param <D>
  * @param criteria
  * @param qo
  * @param class1
  * @return
  */
 public <E, D extends Dto> DtoResultWithPageInfo<D> queryPageListByCriteriaWithQo(PageQo qo, Class<D> dtoClazz);

}

其中定义了一些对数据库的抽象公共操作方法,代码中有注释,可以对照理解。

4.2 看下HibernateTemplateDao.java对BaseDao.java的抽象实现

import com.fxmms.common.dao.BaseDao;

后续介绍,现在暂时有个印象。
在www中的dao层有与各具体类(数据表)相对应的数据库操作实现:

上图声明了三个具体类对应的接口声明:AdminDao、MacDao、TaskDao。
对应三个接口有三个具体的实现类:AdminDaoImpl、MacDaoImpl、TaskDaoImpl。
我们以与Admin类相关的dao层操作为例:

}

AdminDaoImpl.java

package com.fxmms.www.dao.hib;

import com.fxmms.common.dao.hib.HibernateTemplateDao;
import com.fxmms.www.dao.AdminDao;
import com.fxmms.www.domain.Admin;

/**
 * Created by mark on 16/11/2.
 * @usage 使用适配器模式,将common层中定义的公共访问数据库方法实现嫁接到Admin类的接口中。
 */
public class AdminDaoImpl extends HibernateTemplateDao<Admin> implements AdminDao {

    @Override
    protected Class<?> getEntityClass() {
        // TODO Auto-generated method stub
        return Admin.class;
    }
}

可以看到,在具体类相关的数据库操作实现类中,我们只需要实现HibernateTemplateDao<T>中抽象方法protected Class<?> getEntityClass();即可。
给我们的感觉就是这个方法的实现是画龙点睛之笔。
回过头去看,在HibernateTemplateDao类中所有与数据库操作有关的方法:
例如:

 @Override
 @SuppressWarnings("unchecked")
 public T getByUniqueKey(String columnName, Object value) {
  return (T) getSession().createCriteria(getEntityClass())
    .add(Restrictions.eq(columnName, value)).uniqueResult();
 }

getEntityClass()方法最终都会被具体的类所实现。这个设计真的是很巧妙。

webapp下有res文件夹,用于存储静态文件,WEB-INF文件夹下有view文件夹用于放置应用中jsp页面。

6.配置tomcat 运行环境


项目搭建已经完毕,接下来需要做的就是配置项目的运行环境了,这里我们采用tomcat来充当应用服务器。
6.1 去官网下载tomcat 8.0http://tomcat.apache.org/download-80.cgi
6.2 配置 tomcat 服务器:
点击Edit Configurations

装载开发版(exploded)应用war包,此步骤有两种方式:
第一种方式:选择Deploy at the server startup下方的+,入下图所示:
