maven web 应用配置

内容简介：maven web 应用配置

太久没有使用 java 有点生疏了，所以特意使用eclipse，通过maven 配置一下java web工程（本文仅用做个人查阅之用）。

安装jdk和eclipse

jdk的下载可以在360软件管家等地方下载，eclipse可以在官网下载（java ee版本）

eclipse自动补全

Windows -> Preferences -> Java -> Editor -> Content Asist -> Auto activation triggers for Java

添加.abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

eclipse maven 源配置

新建一个xml文件：

<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">  
        <mirrors>  
        <mirror>  
            <id>alimaven</id>  
            <mirrorOf>central</mirrorOf>  
            <name>aliyun maven</name>  
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
        </mirror>  

        <mirror>  
            <id>ui</id>  
            <mirrorOf>central</mirrorOf>  
            <name>Human Readable Name for this Mirror.</name>  
            <url>http://uk.maven.org/maven2/</url>  
        </mirror>  

        <mirror>  
            <id>jboss-public-repository-group</id>  
            <mirrorOf>central</mirrorOf>  
            <name>JBoss Public Repository Group</name>  
            <url>http://repository.jboss.org/nexus/content/groups/public</url>  
        </mirror>  
    </mirrors>  
</settings>

下图箭头输入的文件就是上面输入的文件路径

启动web服务

由于用了maven，所以不是以前那种安装一个tomcat，然后点击run。

而是先在run configuration配置，如下图：

请注意默认是写tomcat:run，图上配置是使用了插件（默认是tomcat6运行）

然后在工程右击，run as -> maven build即可启动服务

使用tomcat7运行

首先在工程的pom.xml文件的build标签加入一段代码，如下表：

<build>  
    <finalName>test</finalName>
    <plugins>  
             <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.1</version>
                <configuration>
                    <port>8080</port>
                    <path>/</path>
                    <uriEncoding>UTF-8</uriEncoding>
                    <finalName>test</finalName>
                    <server>tomcat7</server>
                </configuration>
            </plugin>
        </plugins>  
  </build>

path: 配置项目URL根目录

port：端口

finalName: 应该是工程名字

配置一个简单spring mvc工程

在pom.xml文件加入依赖，完整内容如下表：

修改web.xml文件配置：

<!DOCTYPE web-app PUBLIC  
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>  
  <display-name>Archetype Created Web Application</display-name>

     <!-- Spring的log4j监听器 -->  
    <listener>  
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>  
    </listener>  

    <!-- 核心控制器 -->  
    <servlet>  
        <servlet-name>springMVC</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <init-param>  
            <param-name>contextConfigLocation</param-name>  
            <param-value>/WEB-INF/applicationContext.xml</param-value>  
        </init-param>  
        <load-on-startup>1</load-on-startup>  
    </servlet> 
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  
    <servlet-mapping>  
        <servlet-name>springMVC</servlet-name>  
        <url-pattern>/</url-pattern>  
    </servlet-mapping>  
</web-app>

WEB-INF/applicationContext.xml文件配置：

<?xml version="1.0" encoding="UTF-8"?>  
<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"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
                        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 
                        http://www.springframework.org/schema/mvc 
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 
                        http://www.springframework.org/schema/context 
                        http://www.springframework.org/schema/context/spring-context-4.0.xsd 
                        http://www.springframework.org/schema/aop 
                        http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 
                        http://www.springframework.org/schema/tx 
                        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
    <!-- 设置使用注解的类所在的jar包 -->
    <context:component-scan base-package="controller" />
</beans>

新建一个包，名字叫做controller。在这个包下面新建一个文件Welcome.java，代码如下：

package controller;

import org.springframework.stereotype.Controller;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class Welcome {

    @RequestMapping("/welcome")
    public @ResponseBody String index(){
        return "welcome to visit !";
    }

}

然后启动服务，访问 http://127.0.0.1:8080/welcome 即可看到效果。
