eclipse maven 搭建【SSH】项目

一、新建maven项目

选中maven-aechetype-webapp

group Id一般为公司域；Artifact Id相当于项目名称；version不需要更改；Package不使用默认，手动清空

Finish

项目结构如图报错是因为没有加入servlet API 暂时不用管。

二、配置pom.xml

  1　　　　<properties>

  4

保存，Maven会自动联网去下载所有需要的jar包，只写jar的名字，不用记住，只要去Maven中央仓库去搜索，Maven中央仓库地址：http://search.maven.org/完成之后，多了很多jar，并且都放到了配置的本地仓库中，以后要再使用相同版本的jar时候，就不需要联网下载了。

三、修改项目结构

因为构建的MSSH项目的结构并不是一个标准的Maven结构，我们需要手动新建几个Source Folder

这是标准的maven项目结构

src/main/java:存放java源文件

src/main/resources:存放项目配置文件，如spring.xml,hibernate.cfg.xml。。。

src/test/java:存放test的java文件

src/test/resources:存放test时候所需的配置文件

配置Source Folder的output folder

同步项目的jdk版本

设置web.xml的路径

further configuration available若没有出现可以先去掉dynamic web module的勾 apply之后再打上勾就会出现此选项设置路径为src/main/webapp

四、编写配置文件

web.xml

 1 xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

hibernate.hbm2ddl.auto=update

spring.xml

扫描com.shi包下的文件

struts.xml

使用零配置，扫描com.shi包下的文件

xml version="1.0" encoding="UTF-8"?>
DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">

    <constant name="struts.i18n.encoding" value="utf-8" />
    <package name="defaultPackage" namespace="/" extends="struts-default">

五、使用

 
   User

 
   UserDao

 
   UserManager

 
   UserAction
