eclipse 創建maven 項目 動態web工程完整示例

 

 

eclipse maven工程自動添加依賴設置

maven工程可以在線搜索依賴的jar包,還是非常方便的

但是有的時候可能還需要設置下

eclipse不能在線搜索jar包 報錯

如果搜索不到內容,或者有報錯信息(index downloads are disabled ,search results may be incomplete)

windows  preference   maven   勾選上

然后  windows  show views

rebuild一下

就可以搜索了

注意這個地方的scope,暫且不管

我們輸入spring-webmvc,找到我們需要的,單擊一下就好了

還有就是,version只要是存在的版本,我們可以手動寫的

添加了之后,順手更新了下項目(注意,不是必須要做的哈,只是我手欠了)不過你早晚或許都會需要更新下

 

然后捏

尼瑪,報錯了....

想了一下不應該啊,都修改好了的

回頭一看

我的jdk版本,還有eclipse的一些配置,都尼瑪改回來了,還原了....

腫么了這是?

忘記設置了!!!!!

maven update project后版本還原,jdk還原了!

Maven 3.0 source和target的默認設置都是1.5，與運行Maven時的JDK版本無關，除非在項目的POM文件中顯示的指定一個版本，否則每次更新后都會使用編譯器默認的source/target版本1.5。

所以,把原來修改過的東西修改回去先......

然后pom.xml中顯示的指定這一段

<build>  

    <plugins>  

        <plugin>  

            <groupId>org.apache.maven.plugins</groupId>  

            <artifactId>maven-compiler-plugin</artifactId>  

            <version>3.3</version>  

            <configuration>  

                <!-- 指定source和target的版本 -->                 

                <source>1.8</source>  

                <target>1.8</target>  

            </configuration>  

        </plugin>  

    </plugins>  

</build>

(如果有build標簽了,就是plugins這一段)

然后在更新下  update project

剛才的錯誤就沒了

我們剛才引入了spring-context  spring-webmvc發現多了好幾個

這就是maven好處,它所依賴的包,會自動下載的...

我們再繼續添加一個mybatis-spring

最后的結果就是這樣子

HelloWorld.java

package springmvcMaven;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.FileSystemXmlApplicationContext;

public class HelloWorld {

public static void main(String[]args){

        ApplicationContext ctx = new FileSystemXmlApplicationContext("src/helloWorld.xml");

        HelloWorldSpringBean helloWorldSpringBean = (HelloWorldSpringBean)ctx.getBean("myHelloWorld");

helloWorldSpringBean.show();

    }

}

HelloWorldSpringBean.java

package springmvcMaven;

public class HelloWorldSpringBean {

private String hello;

public String getHello(){

return hello;

    }

public void setHello(String hello){

this.hello=hello;

    }

public void show(){

        System.out.println("--message--"+getHello());

    }

}

helloWorld.xml  在src的根目錄下

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

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

<bean id="myHelloWorld" class="springmvcMaven.HelloWorldSpringBean">

<property name="hello">

<value>hello World spring!</value>

</property>

</bean>

</beans>

項目的結構就是這樣子

右鍵  run as,打印信息成功

spring跑通 

現在開始測試一下springmvc的情況

為了接下來的項目的規范性,我們重新規划下項目的結構以及配置文件

這個是最新的結構

說白了新建了幾個包,用於區分不同的功能划分,controller用於控制跳轉,domain用於存放JavaBean,dao用於操作數據庫相關,service用於相關接口的實現

mapper用於mybatis的xml文件

另外還有兩個配置文件

ApplicationContext.xml

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

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<context:component-scan base-package="com.noteless.bbs.domain" />

</beans>

springmvc.xml設置了自動掃描的controller的類包,並且設置了視圖解析

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

<beans xmlns="http://www.springframework.org/schema/beans"

<property name="suffix" value=".jsp" />

</bean>

</beans>

web.xml 中指定了配置文件的路徑,以及配置了servlet

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

<web-app version="3.0"

xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet>

<servlet-mapping>

<servlet-name>bbs</servlet-name>

<url-pattern>*.do</url-pattern>

</web-app>

controller里面新建一個LoginController.java

package com.noteless.bbs.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

public class LoginController {

@RequestMapping(value="/welcome")

public String toLoginPage(HttpServletRequest request){

return "welcome";

}

}

在views下面新建了一個歡迎頁面

welcome.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>標題</title>

</head>

<body>

歡迎光臨!

<br>

歡迎光臨!

</body>

</html>

我們啟動server,然后運行項目

可以看到springmvc的配置也沒有問題

接下來是鏈接數據庫,以及配置mybatis

剛才引用了一些包但是還遠遠不夠,此處不再一一介紹沒一個引用的包的作用以及何時引入了,貼出來我用到的包,

有了這些包就可以開始我們后續的項目了

注意;如果是項目搭建初期,如果有報錯,我建議,先看看常用的或者必須要用到的一些包是不是缺失,都弄過來

如果還有報錯,再去看具體的原因

當然如果你非常熟悉的話,看一眼報錯就知道缺什么包那就最好了,估計你要是還在看我的文章,說明你不牛...

配置數據庫以及配置mybatis

這個工程示例,是接着我的之前的文章中的示例寫的,功能一樣,結構不一樣(之前的沒用maven)

一些javaBean類以及service 都直接拿過來用了

有興趣的翻一下其他的文章

現在的結構為:

   其實,這幾個文件是最重要的哈,還有jar包..

把接口  javaBean挪過來之后,配置處理好之后,測試一下,可以執行通過

這樣一個完整的springmvc+mybatis+maven的項目就搭建完成了

哦,對了,還有一個log4j,它的使用也很簡單

應用jar包

並且配置下配置文件即可

具體的可以參考我的工程直接eclipse導入即可了

springmvcmybatisMaven-002.rar      http://pan.baidu.com/s/1sknL8rb

防止鏈接失效,代碼都貼出來吧..

一下就是所有的代碼,建議下載我的工程,導入eclipse慢慢研究
